Supports PDF files
Compress your resume PDF to fit email attachment limits (often 5-10MB). Strong mode can shrink a scanned resume to under 100KB for online form uploads.
Government portals, scholarship applications, and visa forms often cap PDF size at 100KB or 1MB. Hit the target with Light or Strong mode — no upload required.
Shrink large PDF reports before attaching to Gmail, Outlook, or Slack. Recipients get the same content in a fraction of the size — no quality loss in Light mode.
This tool uses lossless structural compression. It re-serializes the PDF to reduce size without degrading content.
Results vary. Already-optimized PDFs may see little reduction, while verbose PDFs can shrink significantly.
Light mode uses lossless structural compression (best for text PDFs, 5-20% smaller). Strong mode rasterizes each page as a compressed JPEG image (best for scanned/image PDFs, up to 80% smaller, but text becomes non-searchable).
No. PDF compression runs entirely in your browser using WebAssembly. The maximum file size is 50MB per file; very large files may be slow.
