Frequently asked questions

Is ConvertLocal really free? +<br>Yes — no sign-up, and no watermark on what you convert or resize.

Do you store or see my files? +<br>No. The converter and image tools run inside your browser using WebAssembly and Canvas. Your file is never uploaded to a server.

What formats are supported? +<br>Video: MP4, MOV, WebM, MKV, and GIF. Audio: MP3, WAV, OGG, FLAC, AAC, and M4A. Images: JPG, PNG, and WebP.

Can I resize or convert images too? +<br>Yes — the Image Tools tab resizes, compresses, and converts between JPG, PNG, and WebP, entirely in your browser.

How does the AI image generator work? +<br>It sends your prompt to an image generation API and returns a picture — no sign-up needed. Free anonymous use is limited to roughly one image every 15 seconds; that's a limit set by the image API itself, not this site.

Is there a file size limit? +<br>No hard limit, but since your device does the work, very large files will simply take longer.
