Right-click compress: make videos, images and audio smaller, entirely on your own computer.
Free and open source, for Windows, macOS and Linux.
Test versions (0.1.x). rc-compress is in early development. It works, but expect rough edges; installed copies update themselves (Settings → About → Check for updates).
From the latest release:
| Your system | File |
|---|---|
| Windows 10/11 | rc-compress_<version>_x64.exe |
| Mac with Apple Silicon (M1 or newer) | rc-compress_<version>_aarch64.dmg |
| Mac with Intel | rc-compress_<version>_x64.dmg |
| Linux (Ubuntu, Debian) | rc-compress_<version>_amd64.deb |
| Linux (any) | rc-compress_<version>_amd64.AppImage |
The downloads aren't signed yet: Windows may show "Windows protected your PC" (More info → Run anyway), and macOS may say the app is damaged or from an unidentified developer (right-click the app → Open).

Shrinks videos, images, audio and PDFs, with full control over format, quality, size, resolution and more, or one click with a preset. HDR is kept (or removed, or boosted), and many files can be compressed at once.
-
Nothing is uploaded: every file is compressed on your computer. The only network use is checking for updates.

Coming: the right-click menu on macOS and Linux.
rc-compress is a fork of compressO by Code For Real, which does the compressing (with FFmpeg and other open-source tools; see THIRD_PARTY_NOTICES.md). Thank you to its authors. Everything compressO does, rc-compress does too, including its command line tool (Settings → CLI).
AGPL-3.0, like compressO.
How the project is built and checked: CLAUDE.md and AGENTS.md. Run the app with
pnpm install and pnpm tauri:dev. More in docs/.
