Shrinkray on Web Browser
Runs in any modern browser — nothing to install, works the same on any machine you log in from.
Setup on Web Browser
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 Web Browser — 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.
