Frequently Asked Questions
Which input formats work?
WAV, M4A, OGG, FLAC, AAC and MP3 are shown. Other formats may work if the engine can decode them.
Will quality change?
Converting to MP3 at a lower bitrate than the source reduces quality. 320 kbps keeps the most.
What is the maximum file size?
500MB is a refusal limit, not a guaranteed processing limit. Files over 500MB are refused. A file at or below 500MB is not guaranteed to process successfully. Reliable processing limits vary by tool, file, and device, and have only been verified for the cases in the test record (for example, trimmer segment processing at 492 MB and full audio transcode at 99 MB). A full-video re-encode at 500 MB has not been tested.
Does my file get uploaded anywhere?
This build is designed so processing runs in your browser, without sending your file to a server. In testing, tool runs made no requests outside this site. When you first use a tool, your browser loads the processing engine from this site itself; your file itself is not sent anywhere.
