About this tool

Compress PDF matches reduce pdf file size online free, make pdf smaller for email, compress scanned pdf, and shrink pdf without losing quality. ScanText offers two modes that run entirely in your browser: Light, a lossless structure optimization that cleans up file overhead without touching image data, and Balanced, which re-encodes scanned pages at 92%+ JPEG quality to cut size noticeably on photo-heavy documents while keeping text legible. Pick Light for PDFs that are mostly text — contracts, reports, exported documents — where every byte of precision matters. Pick Balanced for multi-page scans, photographed receipts bundled into one file, or anything an email server is rejecting for being too large. No signup, no sending files to ad-heavy portals that hold your document hostage behind a download timer.
