Shrinkray on Linux
Build from the open source or run the desktop build on Linux — same pay-once license, no telemetry.
Setup on Linux
Download the installer
Download the latest Shrinkray installer from the GitHub Releases page (https://github.com/bensblueprints/image-compressor-mvp/releases) — or build it yourself from the MIT source.
Install
Run the installer — one click, no terminal, no account to create.
Run it locally
Shrinkray runs 100% on your machine — no account, no telemetry, and it keeps working with the Wi-Fi off.
What works offline: everything. Shrinkray is a desktop app — once it's installed, no feature needs a connection to us.
Shrinkray on Linux — honest answers
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/image-compressor-mvp. $19 gets you the signed installer, 1-click setup and updates.
Is the compression as good as TinyPNG?
It uses sharp/libvips with mozjpeg-grade encoders — the same engines behind most professional pipelines. At equal quality settings, results are comparable; you also get AVIF, which typically beats PNG/JPG sizes outright.
