Compress PDF
Compress PDF files for email, uploads, and storage. Reduce file size while keeping text readable and choosing the right quality tradeoff.
What this tool is best for
Use Compress PDF when the file is too large to send, upload, or store comfortably, but still needs to remain readable and presentation-safe.
Why people use it
- Targets one of the strongest commercial PDF intents: making oversized files small enough for email and web submission.
- Gives users a clearer quality-versus-size choice than generic export menus.
- Works well for scan-heavy PDFs where image compression creates the biggest savings.
What to watch for
- Compression gains vary widely; text-heavy PDFs may shrink less than image-heavy scan files.
- Aggressive compression can soften images, so users may need to choose a lighter setting for print-sensitive documents.
Supported inputs
single PDF or small batches, scan-heavy PDFs, upload-ready documents
Common outputs
smaller PDF files, lighter email attachments, web-friendly documents
About This Tool
Compress PDF is the page users need when a document is ready to go, but the file size blocks the next step. That next step is usually practical: attaching a PDF to email, uploading it to a portal, fitting under a procurement limit, or reducing storage cost across recurring scan workflows.
The best compression tools do not just “make files smaller.” They help users choose the right tradeoff for the job. A board pack that needs to look polished on-screen should not be treated the same way as a scan archive that only needs to stay legible. This page gives users a more direct answer to queries like “reduce PDF size” by framing compression as a quality decision, not just a button press.
Compression is especially valuable for scan-heavy PDFs, image-first reports, and exported presentations where large embedded assets make the file cumbersome. Text usually remains crisp, while images and background detail are where the tradeoff shows up. That is the part users want explained before they trust an online compressor.
If the PDF is broken rather than oversized, route users to Repair PDF. If the issue is privacy, not size, Remove Metadata or Sanitize PDF is the better next step.

Frequently Asked Questions
How much can I reduce the file size?
Compression results vary based on the PDF content. Image-heavy PDFs can often shrink much more than text-only PDFs.
Will compression affect text quality?
Text usually remains sharp and readable. Images, scans, and background graphics are where quality tradeoffs are most visible.
Which compression level should I choose?
Use lighter compression for print-sensitive files and stronger compression when email or upload size limits matter more than image detail.
Can I compress multiple PDFs at once?
Yes, you can upload and compress up to 10 PDF files simultaneously.
Should I compress before or after merging PDFs?
Merge first if you need one final packet, then compress the merged PDF so the final deliverable meets size limits.
