Compress PDF
Honest note: This tool removes unused data and optimizes the PDF structure. For heavy image-based PDFs, size reduction may be modest (5-30%). For text-heavy PDFs, results are typically better. Deep image recompression requires server-side processing, which would mean uploading your file. We don't do that.

Frequently Asked Questions
How much can I reduce a PDF file size?
Results vary. Text-heavy PDFs with unused metadata can see 10-40% reduction. Image-heavy PDFs may see 5-20% with this browser-based tool, since deep image recompression requires server-side processing.
Will compression reduce PDF quality?
No. This tool removes unused objects and optimizes file structure without touching visible content. Text, fonts, and images remain unchanged.
What is the best way to compress a PDF?
Use the Strong compression setting for maximum reduction. If your PDF was created from scanned images, the reduction may be modest since the images are already compressed within the file.
Why is my compressed PDF similar in size?
If the PDF was already optimized or consists mainly of compressed images, there is little unused data to remove. This is a known limitation of client-side compression, and we are upfront about it.
Can I compress a PDF without losing text quality?
Yes. This tool does not alter text or fonts. Text remains fully readable and searchable after compression.
