How to compress a PDF
Drop your PDF, pick a compression level, and click Compress. The tool rasterizes each page to a JPEG and re-packages it - image-heavy PDFs shrink the most.
High compression rasterizes each page to a JPEG - smallest file, lower text sharpness.
Step-by-step
- 1Drop your PDF. Add the file you want to compress.
- 2Pick a quality. Choose low, medium, or high compression.
- 3Download. Click Compress. Save the smaller PDF.
How much smaller will my PDF be?
It depends on the content. Image-heavy PDFs (scans, brochures) often shrink 60–90%. Text-only PDFs may shrink less because text is already compact. The tool shows the before/after size so you can decide whether to save the result.
Which level should I pick?
Medium is the safe default. Low keeps sharp text with modest savings. High squeezes hardest - best for scans where text sharpness isn't critical.
Does it work for scanned PDFs?
Yes, scans compress especially well because they're already images. Text-searchability may be lost during rasterization - use the Extract Text tool first if you need to preserve it.
