How to use Compress PDF
Compress PDF shrinks a heavy PDF so it fits an email attachment limit or an upload form. Supported embedded images are recompressed inside your browser without turning pages into pictures.
Step by step
- 1Pick a compression level — Balanced suits most documents.
- 2Drop the PDF (scans and image-heavy files shrink the most). Compare the Before and After page thumbnails.
- 3Download the compressed PDF, or try a stronger level if it is still too big.
What to expect
- Image-heavy PDFs may shrink substantially; text-only files and already optimized images may gain little.
- Selectable text, vector drawings and links stay intact. Unusual image formats and masked images are left unchanged.
- Processing time depends on image size and your device. Digitally signed documents should retain their original copy.
Common use cases
- Preparing a contract, invoice or report before sending it.
- Assembling scanned pages into a single tidy document.
- Extracting just the pages a colleague or portal actually needs.
- Fixing a PDF that a scanner or printer produced badly.
