Frequently asked

How much smaller can the PDF get?

Typically 30-70%, depending on content. Image-heavy PDFs compress best.

Will quality suffer?

Pick from Low / Medium / Max compression. Medium is the sweet spot for most documents.

Is the PDF uploaded anywhere?

No. Compression happens in your browser. Big files never leave your device.

Any file size limit?

Most online compressors cap at 10-50MB for free users. We don't. Compress 500MB if your browser can handle it.

Does it strip metadata?

Yes - author, creator, and producer fields are removed for privacy. Title is preserved.
