Your documents, your privacy
Core page editing runs in your browser. Compression uses our server: your PDF is uploaded temporarily. Results remain in server memory for up to 20 minutes. Use HTTPS for encrypted transport. Limited service analytics help improve reliability.

Make room for what matters.
Use a PDF up to 10 MB. Scanned PDFs often compress more than text documents. The achievable size depends on the document and settings.
HOW IT WORKS
Three simple steps.
- 01Choose a PDF, then select a target size, image quality, resolution and color setting.
- 02Accept temporary server processing, then start compression and follow its progress.
- 03Download your result. Server results expire after 20 minutes.

Frequently asked questions
Will it reduce a PDF by 50%?
Not necessarily. Every PDF is different. We show the actual reduction and preserve the original if compression would make it larger.
How long will I wait?
Follow the upload and processing progress on this page. Processing time depends on document complexity and service demand.
Can compression reduce image quality?
Yes. Lower image quality or resolution can reduce detail. Choose Good or Best when image quality matters. Target sizes are not guaranteed.
Options and limitations
Choose 50, 100, 200, 300 or 500 KB, or 1, 2 or 5 MB. To compress a PDF to 200 KB, select 200 KB, choose Medium/Good/Best quality and 72/144/288/720 PPI, then review readability and the target-achieved result. Targets are best-effort: lowering quality or resolution can remove image detail. Here KB means 1,024 bytes; the 1 MB preset targets 1,000 × 1,024 bytes.
