Compress PDF

SecurePDF can reduce PDF file size by 40-90% depending on the content. PDFs with high-resolution images compress the most, while text-heavy documents see smaller reductions.

Light compression preserves nearly all visual quality. Heavy compression reduces image resolution but keeps text sharp. You can preview the result before downloading.

Yes, SecurePDF offers free PDF compression with no signup required. Free users can compress files up to 100 MB, 20 operations per day.

Files are encrypted with AES-256 at rest and processed in an isolated worker, then auto-deleted within 1 hour (Free) or 24 hours (Pro / Teams). We only read them long enough to run the operation you requested.

Batch compression is available for Pro users. Free users can compress one file at a time.

Two modes: Light (fast, minimal quality loss — best for sharing and email) and Heavy (maximum size reduction, trades visible quality for smallest file).
