Put the file down. The tools come to it.
Every job runs inside this tab. Your file never uploads, so there is no queue, no size limit and nothing to delete afterwards.

Why nothing leaves your computer
A merge, a compression, a trim: each one is code that runs in your own browser tab. That is not a privacy promise you have to take on trust; it is how the tools are built. Close the tab and there is nothing of yours anywhere but where it started.
The honest trade is that your machine does the work. A twenty-minute video takes real time. But there is no upload to sit through first, no watermark on the way out, and no upgrade to remove the limit.
- 0 supload time, because there is no upload
- No capon file size or how many at once; your device memory is the only ceiling
- 1 tabis the whole product; chain tools without re-downloading in between
