What is compressing a PDF?
Make an oversized PDF smaller so it fits an email, upload form or archive. This tool re-renders each page to an image locally in your browser and rebuilds the PDF at an adjustable quality — especially effective for scans and image-heavy PDFs. Nothing is uploaded.
How to use it
Select or drop in a PDF.
Drag the quality slider (lower = smaller file).
Compare the before/after size and click Download.
Good to know
This approach turns pages into images, so text is no longer selectable or searchable — ideal for "view / print / send" cases.
Text-only PDFs are already small, so compression gains are limited and may not be needed.
Frequently Asked Questions
Is my PDF uploaded?
No. Compression runs entirely in your browser. Your file is never sent to a server or stored.
How does it compress? Is the text kept?
This tool re-renders each page to an image and rebuilds the PDF — best for scanned or image-heavy PDFs. The trade-off is that pages become images, so selectable text loses its selectability. If you must keep the text, use a different method.
How much smaller can it get?
It depends on the original and the quality setting; scanned PDFs often shrink to a fraction of their size. Lower quality means a smaller file and more visible loss.
