About PDF Compressor

PDF Compressor shrinks PDF file size so documents fit email limits, form uploads, and faster downloads. People searching "compress PDF", "reduce PDF size", or "PDF compressor online" need smaller files without rewriting the whole document.

Upload a PDF, choose a compression level, and download the result. Stronger compression removes more image detail and can soften scanned pages - preview important pages before deleting the original.

Already-optimized text PDFs shrink less than image-heavy scans. If size barely changes, the file may already be efficient or mostly vector text. Keep a master copy for print-quality needs.

Benefits of PDF Compressor

Smaller email attachments Stay under common size caps.
Faster uploads Forms and portals accept the file more easily.
Readable output goal Compression aims to keep text usable.
No desktop software Compress in the browser.

Frequently asked questions

Will compression blur text?

Mild levels usually keep text clear; aggressive levels hurt scanned pages more than pure text PDFs.

Why did size barely change?

Text-only PDFs are often already small; scans and embedded images shrink more.

Is compression lossless?

Typical PDF compression for size is lossy on images - keep originals when quality is critical.

Password-protected PDFs?

Multiple files at once?
