Compress PDF to 500KB when a portal, job application, or government form enforces a strict size cap. Use stronger compression and verify readability after download.
500 KB caps often appear on government and university portals—compress early in your workflow.
Multi-page documents may need splitting before aggressive compression to stay readable.
Secure Server-Side
Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.
How to use this tool
Upload your PDF, apply strong compression, check file size after download, and re-run with adjusted settings if needed.
Worked example
Example: compress a one-page scanned ID from 1.2 MB to under 500 KB for a visa application portal.
When to use this
- Government or university forms with strict caps.
- Job portals limiting resume scan size.
- Mobile upload flows with low size thresholds.
Common examples
- 12 MB scanned contract → Balanced compression often targets email-friendly sizes; text-only PDFs may barely shrink.
- Image-heavy brochure at 25 MB → Strong compression for upload portals; review text readability after download.
- Born-digital 2-page invoice at 400 KB → compression may show little gain; organize or split instead if still too large.
- 15 MB marketing PDF → Balanced mode for email; verify logos after download.
- Scanned 80-page packet at 45 MB → Strong mode for portal upload limits.

How it works
Upload a PDF and choose Basic, Balanced, or Strong compression. The browser uploads your file directly to private temporary storage using a short-lived link. A secure Ghostscript container compresses the PDF, then you receive a temporary download link. Original and compressed files are automatically deleted within one hour.
Limitations
Files upload to a secure server for compression and are auto-deleted within one hour. Scanned PDFs may not shrink much without OCR.
Privacy and file handling
Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.
