Compress PDF
Shrink a PDF's file size.
Best for scanned/image PDFs. Pages are rasterized, so selectable text is flattened to an image.
Compress a PDF
Shrink a PDF's file size by re-rendering its pages as compressed JPEG images at a resolution and quality you choose. This is especially effective for scanned and image-heavy PDFs.
How it works
- Each page is rasterized to a JPEG
- Lower quality and DPI mean smaller files
- Great for scans and image-heavy documents
- Runs entirely in your browser
Important trade-off
Because pages are rasterized to images, selectable text and vector sharpness are lost. For text documents you want to keep selectable, avoid heavy compression.
Private & Processed Locally
Compression happens entirely in your browser; your file is never uploaded.
Frequently Asked Questions
Common questions about the Compress PDF.
How does it compress?
Pages are rasterized to JPEG at a quality and resolution you choose, which greatly reduces size for image-heavy PDFs.
Does it affect text?
Because pages become images, selectable text is flattened. Use lighter settings for text documents.
Are my files uploaded?
Yes. Everything is processed entirely in your browser and your files are never uploaded to a server.
