About this tool
This converter changes an image's file format between the three formats that matter for the web: PNG (lossless, supports transparency), JPG (small files for photos, no transparency) and WebP (modern, small, supports transparency). Pick a target format, set the quality for JPG or WebP, and choose a background colour if you're converting a transparent image to JPG. The image is decoded and re-encoded with the Canvas API in your browser and is never uploaded.
Benefits & use cases
- One tool for every common image format change.
- Switch to WebP or JPG to shrink files for a website.

- Match the exact format a platform or piece of software requires.
Frequently asked questions
Which formats can I convert between?
You can open JPG, PNG, WebP, GIF, BMP and AVIF, and save as PNG, JPG or WebP.
Are my files uploaded?
No. Conversion happens in your browser with the Canvas API and nothing is sent to a server.
How is transparency handled?
PNG and WebP keep transparency. When converting to JPG, transparent areas are filled with the background colour you choose.
Does converting reduce quality?
Converting to PNG is lossless. Converting to JPG or WebP re-compresses the image, so use a high quality setting for the best result.
