Frequently asked questions
Is my JPG file uploaded anywhere?
No. The conversion runs inside your browser using WebAssembly. Your JPG file never leaves your device, which also makes it fast and safe for private files.
Can I convert multiple JPG files to ICO at once?
Yes. Add as many files as you like; they are converted one after another and you can download everything as a single ZIP.
Does converting reduce quality?
ICO is a lossy format. Quality defaults to 100, which has no visible loss; lower it under Advanced options to shrink files.
