SnapOtter

SnapOtter is an open-source, self-hostable suite of 200+ tools for working with images, video, audio, and PDFs. Convert formats, compress, resize, transcribe audio, OCR scans, remove backgrounds, sign documents, and chain tools into repeatable pipelines. A layer-based image editor is built in.

Everything runs on your own hardware. Your files never touch a third-party service, so private documents and unreleased media stay private. No upload quotas, no per-file pricing, no account required. It works fully offline.

Install it in one command with Docker, or run the 3-container Compose stack (app + Postgres + Redis) for production.

It's for anyone tired of pasting sensitive files into random online converters: developers, privacy-conscious teams, homelabbers, and small businesses that want their own file toolkit.

Dual-licensed under AGPLv3 and a commercial license.
