How this conversion works
Everything happens locally in your browser, using the HTML5 Canvas API — the image is read, drawn onto a canvas and re-exported in the new format without ever being sent to a server. That means instant conversion and full privacy.
About PNG and JPG
Since JPG doesn't support transparency, transparent areas in the original image are filled with a white background.
Frequently asked questions
Is my image uploaded to a server?
No. Conversion happens entirely in your browser using the Canvas API — the image never leaves your computer.
Is there a size limit?
Yes, the limit is 20MB per image, to avoid browser slowdowns with very large files.
