Service terms
What the service does, and its limits
What the service does, what it accepts, and the limits it runs under. The legal terms are on the terms and conditions page, and what happens to your file is on the privacy page.
What the service does
Every file is routed into one of five pipelines by its content, not its extension, so a
PNG saved as photo.mp4 is still handled as an image.
| Pipeline | Formats | What is removed |
|---|---|---|
| Text | TXT, MD, JSON, CSV, code | Zero-width characters, Unicode tag blocks, bidi controls, homoglyphs |
| Image | PNG, JPEG, WebP, AVIF, HEIC | C2PA, XMP, EXIF including GPS, PNG text chunks |
| Document | PDF, DOCX, ODT, SVG, HTML, Markdown | Document properties, embedded provenance, hidden characters in the body |
| Video | MP4, MOV, M4V, 3GP, WebM, MKV | Provenance and generator boxes, without re-encoding |
| Audio | MP3, FLAC, WAV, OGG, Opus, M4A | Tag blocks, without re-encoding |
AVI, WMV, FLV, MPEG-TS, RealMedia, WMA and raw AAC have no parser here. They are refused with a clear message rather than written back damaged.
Limits
These exist so a single visitor cannot exhaust a small server. They are enforced on the server, and the interface reads them from it, so you are never offered something that will then be refused.
| Limit | Value |
|---|---|
| Documents and text, per file | 25 MB |
| Images, per file | 10 MB |
| Audio, per file | 10 MB |
| Video, per file | 50 MB |
| Files accepted at once | 10 |
| Audio or video processed at a time | 1 |
| Longest clip for the optional logo eraser | 120 seconds |
A second audio or video clean while one is running is refused rather than queued, so a burst of uploads cannot stack minutes of work onto the server. Requests are also rate limited per address.
Fair use
Use it for your own files. Automated bulk submission, scripted hammering of the endpoints and anything that degrades the service for other people are not welcome, and access may be rate limited or withdrawn. Higher-volume and automated access is not offered today. If that changes it will be announced here.
Availability
This is a free service on a small server, offered without an uptime guarantee. Limits and supported formats may change as it is tuned. Nothing here is a commercial commitment.
What the service does not do
Worth stating alongside the capabilities, because the boundary matters more than the feature list:
- It does not remove SynthID or any watermark carried in the pixels or audio.
- It does not remove a moving logo. The optional eraser only covers a fixed region.
- It does not run pixel-watermark removal, which needs a GPU backend that is not installed.
- It does not store your files, keep an account, or send anything to a third party.
A cleaned file is a file with its records removed. It is not a guarantee of anonymity, and the site will keep saying so.
Common questions
What file size can I upload?
25 MB for documents and text, 10 MB for images, 10 MB for audio and 50 MB for video, with up to 10 files accepted at once. The limits are enforced on the server and the interface reads them from it.
What file formats are supported?
Text and code, PNG, JPEG, WebP, AVIF and HEIC images, PDF, DOCX, ODT, SVG, HTML and Markdown documents, MP4, MOV, M4V, 3GP, WebM and MKV video, and MP3, FLAC, WAV, OGG, Opus and M4A audio. AVI, WMV, FLV and MPEG-TS are not supported.
Is there a limit on how many files I can clean?
There is no total quota. Up to 10 files are accepted at once, and one audio or video file is processed at a time so a burst cannot overload the server.
