- Email attachments: Fit PDFs within email size limits (typically 25MB).
- Faster uploads: Share documents more quickly on portals, forms, and cloud storage.
- Web publishing: Smaller PDFs load faster when embedded on websites.
- Storage savings: Reduce space used by document archives.
- Print submission: Many print services have file size limits for uploads.

Frequently Asked Questions
How much can I reduce a PDF file?
Results vary based on content. Image-heavy PDFs (scans, photos) can be reduced by 50-80%. Text-only PDFs are already small and compress less (10-30%).
Will compression make text blurry?
No. Text and vector graphics are preserved at full quality. Only embedded raster images are compressed.
Can I compress scanned PDFs?
Yes. Scanned PDFs are essentially images and compress very well — often 60-80% reduction.
Can I compress multiple PDFs at once?
Yes. Upload multiple files and compress them all with the same settings.
Is it free?
Yes. Completely free with no watermarks and no sign-up required.
Is my data secure?
Yes. All uploads use TLS encryption. Files are automatically deleted after processing.
