Convert Format
Convert Format changes an image between JPG, PNG and WebP right in your browser. Switch a screenshot to JPG to shrink it, convert to PNG for lossless quality, or move to WebP for the best size-to-quality ratio — with a background colour option when flattening transparency into JPG.

Is converting the right move?
Changing format is the answer to a compatibility problem. It is a poor answer to a size problem.

- It came off an iPhone and nothing opens itHEIC to JPG
What you may lose on the way
- Transparency
PNG and WebP carry an alpha channel; JPG does not. Convert a logo with a transparent background to JPG and the background becomes solid white, permanently.
- Animation
GIF and WebP can hold multiple frames. Converting an animated image to JPG or PNG keeps one frame and discards the rest.
- Quality, if it was lossy already
Converting JPG to JPG re-encodes it, adding a second generation of loss on top of the first. Going to PNG stops further loss but cannot restore what the first encode removed.
Which format for which job
| Format | Best for | Avoid when |
|---|---|---|
| JPG | Photographs, anything with smooth gradients | You need transparency, or the image is flat graphics and text |
| PNG | Logos, screenshots, line art, anything needing transparency | It is a photograph — PNG files will be several times larger |
| WebP | Almost everything web-facing; smaller than both at similar quality | A very old application has to open it |
| GIF | Short looping animation where universal support matters | Still images, or anything with more than 256 colours |

Your file, and what the page does
Your file is never uploaded. Convert Format reads it into this browser tab and processes it with your browser's own Canvas engine on your own device. There is no upload endpoint in the application and no copy on any server — closing the tab discards it.
Because the result is rebuilt from pixels, the source file's EXIF metadata does not survive into it. Camera model, timestamp and any GPS coordinates recorded by your phone are simply not present in the output — a side effect of how canvas encoding works, and a useful one before posting a photo publicly.
What the page does send or fetch
- Ads on the page
- The site is funded by advertising, so the page loads Google AdSense. That carries the usual web basics — IP address, browser, referring page — as on any ad-supported site.
- An anonymous usage counter
- When Convert Format finishes we record that the tool ran, whether it succeeded and how long it took. No file data, no identifier, no cookie.
Your file is not on that list. How this works.
