Your files never leave your device
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
Questions
What counts as large text?
WCAG: 18pt (24px) regular, or 14pt (approximately 18.67px) bold. Below that, the stricter 4.5:1 (AA) and 7:1 (AAA) thresholds apply. Bold 16px body copy is still normal text under the spec, which is a common surprise.
Why does my contrast look fine to me but fail AA?
WCAG contrast is a formula on relative luminance, not a perception test. Thin light-grey type on white often looks acceptable to a young eye in a bright room and still fails 4.5:1. The ratio is the spec; your eye in this room is not.
Do my files get uploaded anywhere?
No. This tool runs entirely in your browser using the Canvas and File APIs. The file you choose is read into memory on your own machine, processed there, and offered back as a download. Nothing is sent to a server, which is also why it keeps working with your network off.
Is it actually free, or is there a catch?
Actually free, with no account and no limit, because it costs nothing to run — the work happens on your device rather than on our hardware. That is different from generating with an AI model on Versely, which does cost credits; there is no free tier for generation.
These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist — video from a prompt, a voice, a score — runs a model, and that costs credits.
