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 it really possible to compress any PDF to under 100KB?
Most text-based PDFs can be reduced to under 100KB using Strong mode. Scanned or image-heavy PDFs may not reach 100KB without visible quality loss, but the tool will achieve the smallest possible size.
Is the PDF compressor free?
Yes, completely free with no signup, no watermark, and no upload. All processing happens in your browser.
Are my files uploaded to a server?
No. Your PDF is processed entirely in your browser using WebAssembly. It never leaves your device.
What's the difference between Light and Strong mode?
Light mode uses lossless structural compression (5-20% smaller, text stays searchable). Strong mode rasterizes each page as JPEG for maximum size reduction — best for reaching aggressive targets like 100KB.
