FAQ

Is it really free?

Yes. The compressor is free with no signup — it's how most people first meet SourceBack.

Will it hit the exact size?

It reaches your target while keeping text selectable where possible; if a target is only reachable by rasterising, it tells you and lets you choose.

Are my files kept?

No — uploads and results auto-delete within 12h.
