PDF Compressor
Try a privacy-friendly structural optimization for a PDF, compare the new size with the original and download the result if it helps.
How to use it
- Choose one PDF up to 50 MB.
- Select Optimize PDF and wait while the browser rewrites the file.
- Compare the original and output sizes. If the new file is larger, you can keep the original instead.
- Download the optimized PDF if it is useful.
Limitations
- This is best-effort structural optimization, not image recompression. Embedded photos and scans are not downsampled.
- The output can be the same size or larger than the input. Compare before using it.
- Password-protected or damaged PDFs may not open. Forms, signatures and advanced PDF features may not be preserved.
- Files are processed in your browser and are limited to 50 MB.
Frequently asked questions
Will it always make my PDF smaller?
No. Results depend on the file. Scans and photos often cannot be reduced by structural optimization alone.
Are PDFs uploaded?
No. The file is read and rewritten in your browser.
Can I compress scanned PDFs?
This tool does not downsample page images. Use a trusted PDF app with image-quality controls for scanned documents.
