Why video is taking longer
Every other tool on slimdocs shares one assumption: your file fits comfortably in memory, gets processed in a couple of seconds, and is handed straight back. That assumption is what lets us promise nothing is ever written to disk, and it holds fine for a 40 MB PDF or a 12-megapixel photo.
Video breaks it. A few minutes of phone footage is easily a gigabyte, and transcoding it is not a two-second job — it is a sustained workload that has to stream through the encoder rather than sit in RAM. Building that properly means a different processing pipeline with progress reporting and resumable jobs, and doing it without weakening the privacy guarantee that the rest of the site rests on.
Rather than ship a video tool that silently caps you at ten seconds of footage or quietly parks your file on a disk somewhere, these are listed here as what they are: not ready yet. The rest of the toolkit works today.
Frequently asked questions
When will the video tools be available?
They are in development. Each one will appear here as a working tool the moment it is ready — there is no waitlist or sign-up to join.
Why not use a browser-based encoder in the meantime?
In-browser transcoding works for very short clips but falls over on real footage, and it drains battery and memory on phones. A server pipeline that handles a full-length video properly is the better answer, so that is what is being built.
Will video tools be free too?
Yes, on the same terms as everything else here: free, no account, and no daily cap.
What can I use today instead?
The PDF, image and developer tools on this site are all fully working. If you need to shrink a video right now, a desktop tool such as HandBrake is the honest recommendation until these ship.
