Fair questions
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.
Will it overwrite my originals?
Never. Output goes to a folder you choose, or next to originals with a _compressed suffix.
Is there an API or CLI?
Not in the app — it's a desktop tool. The MIT source exposes the pure-Node compression pipeline if you want to script it.
Does it phone home?
No. Zero network calls, zero telemetry, no account. You can verify that in the source.
