Compress PDF
Shrink file size by repacking the document and dropping hidden metadata.
Read the step-by-step guide →About this tool
Smaller PDFs upload faster, fit email limits and open quickly in a browser. Our compressor repacks the document with object streams and removes hidden metadata such as producer, keywords and title.
This is a lossless repack: text stays sharp and images are not degraded. Text-heavy PDFs shrink the most. Scans that are already JPEG-compressed shrink very little, so for those reduce the scan resolution at the source.
How it works
- Upload a PDF within the free size limit.
- Press Start — the file is repacked.
- Download the compressed PDF and compare the reported sizes.
Frequently asked questions
How much smaller will it get?
Typically 5–25% for text PDFs exported by older tools, and very little for scans that are already compressed. The result screen shows the exact before and after.
Is page content removed?
No. Only the internal structure is optimised; every page, font and image stays.
Can I compress a password-protected PDF?
Unlock it first — encrypted files cannot be repacked.
