PDF Compressor
Reduce PDF file size by re-rendering each page as a JPEG image at configurable DPI and quality. Shows before/after file size so you can judge the tradeoff. Useful for shrinking scanned documents and image-heavy PDFs before email or upload.

How it works
Each PDF page is rendered to a canvas at the chosen DPI, then saved as a JPEG image and embedded into a new PDF. This is the same method used by most popular online PDF compression services.
Tips
- All processing happens locally in your browser — no files are uploaded.
- Best results on scanned documents, photo PDFs, and image-heavy reports.
- Text-only PDFs may actually get larger — plain text compresses far better than JPEG-encoded text.
- 72 DPI + 50% quality gives the smallest file; 150 DPI + 85% quality retains near-print sharpness.
- After compression, text is no longer selectable or searchable — the pages become images.
- Supports PDF files up to 100 MB.
