FAQ
No. All features (convert, trim, extract audio, add watermark, denoise, vocal separation) run entirely in your browser — no upload needed, ever. Formavide has no servers that process your files. See our Privacy Policy for details.
Your files are never uploaded, so nothing is stored on our side — there is nothing to retain or expire. Everything stays on your device until you delete it yourself.
Input — reads virtually any format: MP4, MOV, AVI, MKV, WebM, MP3, WAV, M4A, OGG, FLAC, Opus, AAC, AIFF and more. Output — converts to: MP4, AVI, MOV, MKV (video) / MP3, M4A, WAV, OGG, FLAC (audio). You can also extract audio from video files.
Files up to 500MB are supported. For best performance, we recommend files under 200MB. Larger files may require more memory.
Local processing has no fixed duration cap — practical limits come from your device memory and performance. Mobile browsers have tighter limits for some features (e.g. local convert max 3 minutes); for long videos, a desktop browser is recommended.
All local tools are free to use with daily usage limits. Pro removes the limits and comes in two one-time tiers — no subscription, no auto-renewal: Quarterly Pass ($9.99, valid 90 days) or Lifetime ($39.99, web version, yours forever).
Full refund within 30 days of purchase, no reason required — request it from your Orders page. This applies to both tiers (Quarterly Pass and Lifetime). The license is revoked automatically once the refund is processed.
Processing speed depends on your device. Large files with high resolution will take longer. On mobile devices, processing may be slower.
Chrome and Edge provide the best experience with multi-threaded processing. Other browsers use single-threaded mode which is slightly slower.
No. Local features are available without an account — just open your browser and start. A free account is optional and unlocks higher daily usage limits.
Yes, Formavide works on mobile browsers. Processing may be slower than on desktop due to device limitations.
After the initial page load, most features work without an internet connection since processing is local.
Yes. Upload a video, then choose an image (PNG/JPG/WebP) or enter text as a watermark. You can adjust size, opacity, rotation (for text), and select multiple positions at once. In single-position mode, you can drag the watermark on the preview to place it precisely. All processing is done in your browser.
The local AI watermark remover is in development — when it ships, removal will run entirely in your browser with no upload. Meanwhile, you can use the watermark tool to add image or text watermarks to protect your own content.
It runs entirely in your browser via ONNX Runtime — your audio never leaves your device. Quick mode uses Spleeter AI (2-stems, ~30MB model); Pro mode uses Demucs AI (4-stems, ~173MB model) for more detailed separation.
