How it works
Reads the image with the browser decoder and writes a new file with the Canvas encoder, so nothing travels over the network.
Frequently asked questions
- Is the transparency preserved?
- PNG, WebP and AVIF keep the alpha channel. JPG does not, so transparent areas are filled with the background colour you choose.
- Are my images uploaded to a server?
- No. The whole conversion runs inside this page using the Canvas API of your browser.
