How to Convert Image Formats

Understanding when to use PNG, JPG, or WebP helps you optimize images for any use case — from web performance to print quality.

Image format conversion is one of the most common tasks in digital media. Each format has distinct strengths: JPG excels at compressing photographs with minimal visible quality loss, PNG preserves transparency and is ideal for graphics with sharp edges, and WebP delivers both lossy and lossless compression with smaller file sizes than either JPG or PNG. Choosing the right format depends on your content type, where it will be displayed, and whether you need transparency.

Converting between formats is straightforward but involves important tradeoffs. When converting from PNG to JPG, you lose transparency — any transparent areas become white. Converting from JPG to PNG does not improve quality since the lossy compression from the original JPG is already baked in, but it does give you a lossless file going forward. WebP offers the best of both worlds for web use, supporting both transparency and efficient compression.

PNG (Portable Network Graphics)

PNG is a lossless format that preserves every pixel perfectly. It supports full alpha transparency, making it the go-to format for logos, icons, graphics, screenshots, and any image where you need transparent backgrounds. The downside is larger file sizes compared to JPG or WebP, especially for photographs. PNG is ideal when quality and transparency matter more than file size — design assets, print-ready graphics, and images that will be edited further.

JPG / JPEG (Joint Photographic Experts Group)

JPG uses lossy compression to dramatically reduce file sizes, making it the standard format for photographs and web images. A quality setting of 80-95 is typically indistinguishable from the original to the human eye while cutting file size by 80% or more. JPG does not support transparency — transparent areas are filled with a solid color (typically white). JPG is best for photographs, social media uploads, email attachments, and any scenario where small file size matters more than pixel-perfect accuracy.

WebP

WebP is a modern format developed by Google that supports both lossy and lossless compression, along with transparency. WebP files are typically 25-35% smaller than equivalent JPG files and 26% smaller than equivalent PNG files with comparable quality. All modern browsers support WebP. It is the preferred format for web optimization, combining the photograph-friendly compression of JPG with the transparency support of PNG in a smaller package.

Image Conversion Use Cases

Web Optimization

Convert large PNG screenshots and graphics to WebP or JPG to reduce page load times. WebP typically delivers 25-35% smaller files than JPG with the same visual quality, improving Core Web Vitals scores and user experience on your website.

Transparency Needs

Convert JPG product photos to PNG after removing backgrounds, or convert to WebP to maintain transparency with a smaller file. PNG and WebP both support alpha channels, essential for logos, product images on custom backgrounds, and overlay graphics.

Email Compatibility

Many email clients have limited format support and strict file size limits. Converting images to JPG ensures maximum compatibility across all email platforms and keeps attachment sizes manageable for recipients with slow connections.

E-commerce Listings

Online marketplaces like Amazon, eBay, and Etsy have specific image format requirements. Convert product photos to the required format with optimal quality settings to meet listing requirements while maintaining sharp, professional-looking images.

Print Preparation

Print workflows often require specific formats. Convert web-optimized WebP or JPG images to high-quality PNG for print use where lossless quality matters. While TIFF is the traditional print standard, high-resolution PNG provides excellent results for most print applications.

Social Media

Each social platform handles image formats differently. Instagram compresses JPG uploads aggressively, while Twitter preserves PNG quality for images under 900px. Converting to the optimal format for each platform ensures your images look their best when posted.

Frequently Asked Questions

Is my image uploaded to a server?

No. All conversion happens in your browser using the HTML5 Canvas API. Your image never leaves your device — completely private and secure.

What is the difference between PNG and JPG?

PNG uses lossless compression and supports transparency, making it ideal for logos, graphics, and screenshots. JPG uses lossy compression for much smaller file sizes, best for photographs and web images. PNG preserves every pixel perfectly; JPG sacrifices some quality for dramatically smaller files.

What is WebP and why should I use it?

WebP is a modern image format developed by Google. It produces files 25-35% smaller than JPG and 26% smaller than PNG with comparable quality. WebP supports both lossy and lossless compression plus transparency. All major browsers support WebP, making it the best choice for web optimization.

Does converting JPG to PNG improve image quality?

No. Converting JPG to PNG does not restore quality lost during JPG compression. The lossy compression artifacts from the original JPG are permanent. However, converting to PNG ensures no further quality loss occurs if the image is saved again, since PNG is lossless.

What happens to transparency when I convert to JPG?

JPG does not support transparency. When you convert a PNG or WebP image with transparent areas to JPG, the transparent regions are filled with white. If you need to preserve transparency, use PNG or WebP instead.

What JPG quality setting should I use?

For most uses, 85-92 provides an excellent balance of quality and file size. Quality above 95 produces diminishing returns with much larger files. For web use, 80-85 is often sufficient. For archival or print purposes, use 95-100. Below 70, compression artifacts become noticeable in detailed areas.

Can I convert GIF or BMP images?

Yes. The tool accepts any image format your browser can display, including GIF, BMP, TIFF, and SVG. You can convert these to PNG, JPG, or WebP for broader compatibility and smaller file sizes. Note that animated GIFs will be converted as a single static frame.

Which format produces the smallest file size?

For photographs, WebP typically produces the smallest files, followed by JPG, then PNG. For graphics with flat colors and sharp edges, WebP lossless and PNG are often comparable, both smaller than JPG. The actual size depends on image content, dimensions, and quality settings.

Does converting images change their dimensions?

No. Format conversion preserves the original width and height of your image exactly. Only the encoding format and compression change. If you need to resize an image, use a dedicated resizing tool.

Is there a file size limit?

No enforced limit. The tool handles any image size your browser can process. Very large images (50+ megapixels) may take a moment to process depending on your device.

Does it work on mobile?

Yes, fully responsive. Works on iPhone, Android, iPad, and any device with a modern browser. The Canvas API used for conversion is supported on all modern mobile browsers.

How many images can I convert?

Unlimited. Since everything runs client-side with no server, there are no daily limits or usage caps. Convert as many images as you need, one at a time.

How do I convert an image to PNG for free?

Upload your image to this page, select PNG as the output format, and click Convert. The result preserves full quality with lossless compression. Download instantly — no signup, no watermarks, no limits.

How do I convert HEIC photos from my iPhone to JPG?

iPhones save photos in HEIC format by default. If your browser supports HEIC display (Safari does natively, Chrome on some systems), upload the HEIC file here and convert to JPG or PNG. If your browser cannot open the HEIC file, change your iPhone settings: go to Settings > Camera > Formats and select "Most Compatible," which saves future photos as JPG.

What is the best image format for websites?

WebP is the best format for websites in most cases — it produces files 25-35% smaller than JPG with comparable quality, and all modern browsers support it. Use WebP for photographs and complex images. Use PNG only for images requiring transparency (logos, icons) or pixel-perfect text. Use SVG for simple graphics and icons (not supported by this converter since SVG is vector-based).

How do I convert PNG to JPG without losing quality?

Some quality loss is inherent when converting from lossless PNG to lossy JPG — that is the fundamental tradeoff. To minimize visible loss, set JPG quality to 95-100. At quality 95, the difference is virtually invisible to the human eye while still achieving significant file size reduction compared to PNG. Note that transparent areas in PNG will become white in JPG since JPG does not support transparency.

Why is my PNG file so much larger than the JPG version?

PNG uses lossless compression — every pixel is preserved exactly, resulting in larger files. JPG uses lossy compression — it discards subtle visual data that humans rarely notice, achieving 5-10x smaller files for photographs. A 5 MB PNG photo might become 500 KB as a JPG at quality 85. The tradeoff is that JPG introduces minor compression artifacts, especially around sharp edges and text.

Can I convert images in bulk?

This tool processes one image at a time, but conversion is instant — upload, convert, download, repeat. For batch converting hundreds of images, command-line tools like ImageMagick or ffmpeg are more efficient. On Mac, the built-in sips command can batch-convert in Terminal.

Does converting to WebP preserve transparency?

Yes. WebP supports both lossy and lossless compression with full alpha channel transparency — making it a superior replacement for both JPG (smaller files) and PNG (transparency support with smaller files). Converting a transparent PNG to WebP typically reduces file size by 26% or more while preserving the transparency perfectly.

What image format should I use for email attachments?

JPG at quality 80-85 for photographs — keeps file sizes small enough to avoid email size limits (most providers cap at 20-25 MB). PNG for screenshots, documents, and graphics with text — text stays sharp. Avoid WebP for email attachments since some older email clients cannot display it.

How do I convert an image for use in Microsoft Word or PowerPoint?

PNG and JPG both work in Microsoft Office. Use PNG for images with text, logos, or graphics that need sharp edges. Use JPG for photographs to keep your document file size manageable. If inserting many photos into a PowerPoint, JPG at quality 85 prevents the file from becoming bloated while maintaining good visual quality.

Complete Image Format Comparison Guide

Understanding the strengths and tradeoffs of each image format helps you choose the right one for every situation.

JPG (JPEG) — The Universal Photograph Format

JPG is the most widely supported image format on the planet. Every device, browser, app, and operating system can open JPG files. It uses lossy compression, meaning some data is discarded to reduce file size — but at quality 85-95, the loss is invisible to the human eye. JPG is ideal for photographs, product images, social media posts, and any image where file size matters more than pixel-perfect precision. It does not support transparency or animation. Use JPG when you need maximum compatibility and small file sizes.

PNG — Lossless Quality with Transparency

PNG preserves every pixel exactly — no compression artifacts, no quality loss, no matter how many times you save it. It supports full alpha transparency (smooth edges, semi-transparent areas) and is the gold standard for logos, icons, screenshots, text-heavy images, and graphics. The tradeoff is file size: PNG files are typically 5-10x larger than equivalent JPGs for photographs. Use PNG when you need perfect quality, transparency, or sharp text.

WebP — The Modern Web Standard

Developed by Google, WebP combines the best of both formats: lossy compression smaller than JPG, lossless compression smaller than PNG, and full transparency support. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. It is the recommended format for websites because it loads faster and saves bandwidth. The only downside is limited support in older software — some desktop apps and email clients cannot open WebP files yet.

When to Convert vs. When to Keep the Original

Convert when changing the delivery context: web-optimized images should be WebP, email attachments should be JPG, logos for print should be PNG. Keep the original format when there is no benefit to converting — a JPG that needs to stay as a photo does not benefit from becoming PNG (it just gets bigger). Never convert JPG to PNG expecting better quality — the lossy data is already gone.

Image Conversion for Web Performance and SEO

Image format and file size directly impact page load speed, Core Web Vitals, and search engine rankings.

Why Image Format Matters for SEO

Google uses page speed as a ranking factor, and images are typically the largest files on a web page — often accounting for 50-80% of total page weight. Converting images from PNG to WebP can reduce page size by 30-50%, directly improving Largest Contentful Paint (LCP), one of the three Core Web Vitals that Google measures. Faster pages rank higher, get more traffic, and convert better.

Recommended Formats by Website Element

Hero images and banners: WebP at quality 80-85 (large images benefit most from smaller file sizes). Product photos: WebP at quality 85-90 for the best quality-to-size ratio. Thumbnails: WebP at quality 75-80 (small display size hides compression). Logos and icons: PNG for transparency or SVG for scalability. Blog post images: WebP at quality 80 balances quality and speed. Background images: WebP at quality 70-75 (backgrounds are less scrutinized).

Serving Different Formats with the Picture Element

Modern web development uses the HTML <picture> element to serve WebP to browsers that support it and JPG as a fallback. This means you often need the same image in two formats. Convert your source images to both WebP and JPG, then let the browser choose. This approach gives you the smallest possible file size for modern browsers while maintaining compatibility with older ones.

Image Conversion for WordPress, Shopify, and CMS Platforms

Most CMS platforms now support WebP uploads directly. WordPress has supported WebP since version 5.8. Shopify automatically converts uploaded images to WebP when serving them. If your platform does not auto-convert, manually converting your images to WebP before uploading is the fastest way to improve page speed without installing plugins or changing your hosting configuration.
