Quality and compatibility

Codec support differs between formats and devices. Re-encoding can reduce quality or increase file size depending on resolution, bitrate and compression settings. Test the downloaded file in its intended player or editor.

Performance and limitations

Media encoding is computationally demanding. Short files below 100 MB are recommended. Browser memory, battery, available storage and device speed affect completion time. DRM-protected or damaged files are unsupported.

Important: Keep the source file, respect copyright and confirm timing, sound, captions and playback before publishing.

Frequently asked questions

Yes. It is free, requires no account and adds no watermark or spoken branding.

Are my media files uploaded?

No. Processing runs inside your browser and selected files are not sent to SolvePilot servers.

Does it work on phones?

Yes, but video encoding uses significant memory. Short files work best, and a desktop is more reliable for larger media.
