Compress PDF
Reduce PDF file size for forms, reports and documents you need to email or upload.
What it does
Reduce the size of a PDF so it is easier to upload, email or read on a mobile connection. Choose a compression level that balances a smaller download against the detail you need in photos, scans and small text.
How to use it
Upload one PDF
Drop or browse for the document you want to compress. The tool accepts one PDF up to 50MB.
Choose a preset
Select Low, Medium, or High compression to control how aggressively the server rebuilds and optimizes the PDF structure.
Compress and download
Run the compression for 1 credit, compare before and after sizes, then download the optimized PDF.
Best for
Email attachments
Shrink client packets, invoices, or reports before sending them through email systems with size limits.
Portal uploads
Prepare PDFs for application portals, vendor systems, or marketplaces that enforce maximum upload sizes.
Document archives
Optimize forms, statements, and administrative PDFs before storing or sharing them with teammates.
Mobile sharing
Create lighter PDFs that are easier to send over chat, mobile networks, or field workflows.
Client deliverables
Clean up metadata and rebuild PDFs into a more compact output before sharing final files.
Tips for best results
- Start with Medium and compare the result with the original.
- Check small print and scanned signatures at full size.
- Keep the original when image detail matters for later printing.
Why use Compress PDF?
Practical advantages built around real creation, selling, and operations workflows.
Simple single-file compression
Upload one PDF, choose a compression preset, and download an optimized PDF with before-and-after file size details.
Quality presets
Pick Low, Medium, or High optimization depending on whether you want light cleanup or a stronger PDF rebuild.
Transparent limitations
The optimizer removes metadata and rewrites PDF structure; image-heavy PDFs may shrink less unless images were inefficiently embedded.
