From your file to your next task
- Choose your files. Check the thumbnail, name and size before you continue.
- Pick an output. Each row lists formats that match the actual source type.
- Convert and download. Get each result or collect completed local files in a ZIP. If a file fails, retry the remaining files without repeating successful conversions.
Check your output before using it
- Play the beginning, middle and end of the result; check audio sync and duration.
- Check additional audio or subtitle tracks separately; conversion may not preserve every stream.

The method, explained
Choose MP4 for compatible playback, WebM for web delivery, GIF for a silent animation or compression for a smaller-file workflow.
Convert a short MOV recording to MP4, then compare its playback with the original.
What to keep in mind
Maximum 20 MB per batch. Processing uses ApyHub and may take a few minutes. GIF uses the first ten seconds at 480 × 270. Codec compatibility and preservation of additional tracks depend on the source. Download links are temporary; save results promptly. Videos are not included in local ZIP downloads.
Common questions
Where is my video processed?
With your consent, videos pass through private ClarityKit upload storage and ApyHub in the USA or Ireland. Our upload chunks are removed after submission; abandoned uploads are removed during later upload activity. Provider source-file retention has not been confirmed. Use non-sensitive videos only.
Does conversion guarantee a smaller file?
No. File size depends on codec, content and settings. Re-encoding can lose quality, and compression may not reduce an already efficient file. Review the result before deleting your original.
