Common Use Cases
Job applicants
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.
Online form submitters
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.
Email senders
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.
FAQ
Is the online PDF compressor free?
Yes, completely free with no signup, no watermark, and no upload. All processing happens in your browser.
Are my PDFs uploaded to a server?
No. Your PDF is processed entirely in your browser using WebAssembly. It never leaves your device.
Will compression reduce quality?
Light mode uses lossless structural compression (5-20% smaller, text stays searchable). Strong mode rasterizes each page as JPEG for maximum size reduction.
What's the maximum PDF size?
Up to 50MB per file. Processing happens in your browser, so very large files may be slow.
