Why convert JFIF to ICO?
JFIF (C-Cube Microsystems, 1992) is best for jpeg files saved with the jfif container extension, and ICO is lossless, so every pixel is preserved exactly. Converting JFIF to ICO makes sense when you need favicons and windows icons — universal (favicons) support, tiny files.
Questions
Is ICO smaller than JFIF?+
ICO files are typically tiny where JFIF files are same as jpg, so in most cases yes. The result depends on the image.
Do my files get uploaded during the conversion?+
No. The JFIF is decoded and re-encoded by your own browser. Open your Network tab and watch it stay empty.
Can I convert several JFIF files at once?+
Yes. Drop a whole batch, convert them together and download the results as a single ZIP.
Is there a file size or daily limit?+
No limits and no account. The only real ceiling is your device's memory, since everything runs locally.
What happens to EXIF and GPS data?+
It's removed. Writing a fresh ICO drops camera, date and location metadata, which is usually what you want before sharing.
Does this cost anything?+
No. There is no server bill to pass on, so converting JFIF to ICO is free and always will be.
