How to use the pdf compressor
- Choose or drop a PDF.
- Pick Standard or Strong compression.
- Select Compress PDF and download the smaller file.
Standard or strong?
Standard rewrites the file more efficiently: it recompresses internal data, packs objects together and drops unused resources. Text, links and quality are untouched, and typical savings are 5–40%.
Strong saves every page as a JPEG picture. It can cut a scanned document or a photo-heavy brochure by 70–90%, but the text is no longer selectable or searchable. Use it when size matters more than editing.
Why a PDF sometimes won’t shrink
Many PDFs are already well compressed. If the result would be bigger than the original, the tool keeps your original and tells you, so you never download a worse file.
Examples
About 2–5 MB
