Compress PDF
Shrink PDFs by re-saving structure or rasterizing pages to JPEG (best for scans).
Runs locally — nothing is uploaded
How to use
- 1
Upload your PDF
Select or drop a PDF file. The tool shows the original file size before compression.
- 2
Choose a mode and settings
Re-save & tidy keeps text selectable (size may shrink slightly or grow). Strong rasterizes pages to JPEG — pick size/quality and optional grayscale; a quick estimate runs first.

Compare and download
Review original vs compressed size and percentage saved. Download the smaller file, or keep the original if the result is larger.
Frequently Asked Questions
Re-save & tidy rewrites PDF structure without changing page content; size may shrink slightly or occasionally grow, and text stays selectable. Strong renders each page as a JPEG — useful for scans, but text is no longer selectable.
Long text PDFs with shared fonts are already small per page. Full-page JPEGs can cost more. The tool samples pages first and warns before processing; try Smallest size and grayscale, or keep the original.
No. Compression runs on your own device inside the browser — the file you shrink never leaves your machine.
Strong mode — Balanced or Smallest size, with grayscale when color is not needed — usually shrinks image-heavy scans the most.
