Shrink PDF Online
- Secure processing
- Automatically deleted
- No signup
- Files are uploaded privately, processed on a secure server, and not retained for later use.
- Uploaded and generated files are automatically deleted within one hour.
Shrink PDF online when attachments bounce or portals reject large files. Compress image-heavy scans and brochures in your browser, then download a smaller file for sharing.
Shrinking works best on image-heavy scans; born-digital text PDFs may show little gain.
Try balanced compression first—aggressive settings can blur small text on scanned pages.
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, choose a compression level, preview if available, then download the shrunk file.
Worked example
Example: shrink a 12 MB scanned contract to under 5 MB for an email attachment without losing readable text.
When to use this
- Email attachments over provider size limits.
- Upload portals with strict file-size caps.
- Sharing brochures or photo-heavy reports.
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.
Important notice
Compression runs on a secure server with Ghostscript. Your file is uploaded privately and automatically deleted within one hour. Already-optimized PDFs may not shrink much. Maximum 50 MB and 200 pages.
