About This Tool
How Browser-Side PDF Compression Works
Unlike server-side compressors that re-encode embedded fonts and images individually, this tool renders each PDF page as an image at your chosen quality, then assembles a new PDF from those images. This is highly effective for scanned PDFs and PDFs full of high-resolution images.
Trade-offs
- Pros: Massive size reduction for image-heavy PDFs (often 70-90% smaller)
- Cons: Text becomes part of the image — it won’t be searchable or selectable after compression
For text-heavy PDFs where you need to preserve searchable text, use the high-quality setting (which keeps text legible) or use a desktop tool like Ghostscript.
Quality Presets
- High — 150 DPI, JPEG quality 85. Slight visual softening, big size drop.
- Medium — 100 DPI, JPEG quality 75. Recommended balance.
- Low — 72 DPI, JPEG quality 60. Visible compression, smallest files.
Frequently Asked Questions
Will text remain searchable after compression?
No u2014 this tool rasterizes pages to JPEG, which means text becomes part of the image. For text-preserving compression, use desktop tools like Ghostscript or qpdf. Use this tool when size reduction matters more than text searchability.
Why is the compressed file larger than the original?
If your PDF is already optimized (vector graphics, small fonts, minimal images), rasterizing it to JPEGs can produce a larger file. This tool excels at compressing scanned PDFs and image-heavy documents. Skip it if your PDF is already lean.
What's the best quality setting?
Medium (100 DPI) is the sweet spot for most documents u2014 readable on screen, significantly smaller. Use High for documents you'll print. Use Low only for archive copies or where size is critical.
