About Compress PDF

Large PDFs are a headache — email services reject them, mobile sharing is slow, and cloud storage fills up fast. iLoveConvert's free PDF compressor re-encodes images inside your PDF at optimized quality levels, dramatically reducing file size without visible degradation. No watermarks. No upload. No waiting for a server.

Most online PDF compressors send your sensitive documents to cloud servers, where privacy is uncertain. Our tool compresses entirely in your browser using PDF-lib, so financial statements, legal contracts, and personal documents stay completely private.

Frequently Asked Questions

How much can PDF compression reduce file size?

Typical results: 30–70% smaller. PDFs heavy with high-res photos compress most. Text-only PDFs compress less since text is already efficient.

Does compression affect text quality?

No. Text in PDFs is vector-based and is not affected by image compression. Only embedded images are re-encoded.

What is the maximum PDF size I can compress?

No server-side limit — the limit is your device's RAM. Most files up to 200 MB process fine on modern devices.

Can I compress a password-protected PDF?

Unlock the PDF first using our Unlock PDF tool, then compress it.

Will there be a watermark on the output?

Never. iLoveConvert is 100% free with no watermarks, ever.
