Image Format Converter
Convert PNG, JPG and WebP images in your browser
Turn a PNG into a WebP, a WebP into a JPG, or anything into a PNG, with a quality slider for the lossy formats. The image is decoded and re-encoded by your own browser and never uploaded.
Everything on this page is processed in your browser. Nothing is uploaded.
What this tool does
Browsers already decode and encode PNG, JPG and WebP, so changing an image's format needs no server and no install. This tool draws your image onto a canvas and asks the browser to write it back out in the format you pick, reporting the size before and after so you can see what the change costs or saves. JPG has no transparency, so a transparent source is flattened onto white rather than turning black.
How to use it
- Choose an image from your device.
- Pick PNG, JPG or WebP, and a quality for the lossy formats.
- Check the size comparison and download the converted file.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- Is my image uploaded?
- No. It is decoded, redrawn and re-encoded by your browser, and the download link points at a file held in the page. Nothing is sent to a server.
- Which format should I pick?
- WebP is usually the smallest for photos and screenshots and every current browser reads it. Use PNG when you need transparency or exact pixels, and JPG when something older has to open the file.
- Why did my transparent background turn white?
- JPG has no alpha channel. The tool fills the canvas with white before drawing, so transparent areas stay light instead of going black. Convert to PNG or WebP to keep transparency.
