About converting JFIF to ICO
Converting JFIF to ICO re-encodes the image in the ICO format using your browser's canvas, so you can switch formats without extra software.

Frequently asked questions
How do I convert JFIF to ICO?
Drag your JFIF image into the tool above and press Convert. FileTinker re-encodes it as ICO in your browser, then you download the result.
Will converting JFIF to ICO reduce the quality?
Converting to ICO re-encodes the image. PNG is lossless, JPG and WebP use light compression to keep files small; FileTinker uses a high-quality setting so the difference is hard to see.
What happens to transparency when I convert to ICO?
JPG has no transparency, so any transparent areas are filled with white. PNG and WebP keep transparency intact.
Are my images uploaded anywhere?
No. Conversion happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
