// frequently asked
How much does this cost?

Nothing. The compressor is free with no sign-up — the same auto-delete and no-account model as the other tools, just a simpler job.

Will text and images still look sharp?

Compression targets your chosen file size while preserving readability; very aggressive targets may show more visible loss.

Is there a page limit?

Up to 200 pages per file.
