Why reduce PDF file size?
Large PDFs are slow to upload, share, and store. Compressing them makes email attachments smaller, saves cloud storage, and speeds up document sharing—without sacrificing readability when done right.
How this online PDF compressor works
Our tool processes your PDF entirely in your browser (no file uploads to a server). It converts each page into a high‑resolution image, then re‑compresses that image using JPEG with an adjustable quality slider. The result is a new PDF that keeps visuals sharp while often reducing the file size by 50–80%.
- Totally private: Your files never leave your device.
- Fast & efficient: Works even with multi‑page PDFs.
- Quality control: Slide to balance size and clarity.
Tips for best results
- Set quality to 80‑90% for near‑original sharpness with noticeable size reduction.
- For documents full of text, try 85‑95% to keep letters crisp.
- If your PDF is still large, slightly lower the slider—few will notice the difference.
- Remember: this tool rasterizes pages, so selectable text is lost. For archival purposes, keep the original uncompressed PDF as well.
Use the compressor above whenever you need a smaller, share‑ready PDF in seconds. It’s free, unlimited, and requires no software installation.
