What makes this converter different
- Nothing is uploaded. Other converters send your file to a server, queue it, and keep a copy for hours. Here the work happens in your browser with WebAssembly, so private videos, voice memos and documents never leave your computer.
- No limits, no sign-up, no watermark. There is no server to pay for, so there is no reason to cap file size or count.
- Real ffmpeg quality. Video and audio use the same ffmpeg encoders professionals use (x264, LAME, libvpx, FLAC), not a stripped-down web codec.

Frequently asked questions
Is it safe to convert WEBP to ICO here?
Yes. The conversion runs entirely inside your browser using WebAssembly. Your file is never uploaded to a server, so nothing can leak, be stored or be seen by anyone. You can even disconnect from the internet after the page loads.
How long does WEBP to ICO conversion take?
Video encoding in the browser runs at roughly 0.5–2× real time depending on your CPU and resolution. A 1-minute 1080p clip takes about 1–2 minutes. Long or 4K videos can take a while; a desktop computer is much faster than a phone.
Is there a file size limit?
There is no server-side limit because there is no server. The practical limit is your device memory: browsers can handle files up to about 2 GB. Very large videos work better on a desktop than a phone.
Will the quality drop?
ICO is a lossy format, so a small amount of detail is discarded. At the default Medium setting the difference is invisible or inaudible for almost all content. Choose High for master copies or Small for messaging and web use.
Can I convert several WEBP files at once?
Yes. Drop or select as many files as you like; they are converted one after another and each gets its own download button.
