How the image converter works
Your image is decoded onto an HTML canvas and re-encoded in the format you choose, entirely inside your browser. No file is ever sent anywhere, so you can convert screenshots, photos or signed scans even on a plane.
Choosing the right output format
- JPG — the universal choice for photographs. Tiny files, supported everywhere, but no transparency.
- PNG — lossless with full transparency support. Best for logos, screenshots and UI graphics.
- WebP — modern format that is typically 25–35% smaller than JPG at the same quality. Supported by every current browser.
Converting in batches
Drop in as many files as you like — each one is converted with the same output format and appears in the results list with its own download link. Transparent areas are flattened onto white when the target is JPG, and preserved for PNG and WebP.
Typical conversions
- Screenshot.png (1.8 MB) → screenshot.webp (240 KB) for a faster-loading help article.
- avatar.webp → avatar.png for a legacy system that rejects WebP uploads.
- logo with transparency → JPG with a white background for a print vendor that only accepts JPG.
Frequently asked questions
How do I convert an image to WebP?
Drop your image in, pick WebP as the output format and click convert. The converted file is ready to download in a second or two, and the whole conversion happens locally in your browser.
Which format produces the smallest file?
WebP usually wins: the same photo is often 25–35% smaller than JPG at similar quality. JPG is next, while PNG is the largest because it stores images losslessly.
What happens to transparency when converting to JPG?
JPG does not support transparency, so transparent areas are flattened onto a white background. Convert to WebP instead if you need to keep transparency.
Does converting lose quality?
Converting between lossy formats (JPG, WebP) re-encodes the image, so a little quality is lost each time. Converting to PNG is lossless, so no further quality is lost from that point on.
