Common questions
What is the difference between fit and fill?
Fit keeps the whole picture visible and fills unused space with your chosen background color. Fill scales the picture to cover the canvas and trims overflowing edges from the center. Neither mode stretches the picture.
Can I resize several videos and keep audio?
Yes. The same canvas settings apply to each video in sequence. Video is re-encoded and original audio tracks are preserved; an error is shown if all audio tracks cannot be kept.
Are my videos uploaded?
No. Videos are processed in your browser without registration. Reloading or closing the page clears your current files and results.
Which formats and file sizes are supported?
Supported containers include MP4, MOV and WebM; codec support depends on your browser. The limit is 500 MiB per file and 1 GiB of source files per batch. Process large files in smaller batches.
