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.
