Optimize & clean up PDFs
Make documents smaller, searchable and tidier — compress, OCR scans, drop to grayscale and strip hidden data.
Optimize & scan — all tools
Compress PDF Server
Shrink file size while keeping it readable.

The Optimize tools improve a PDF without changing what it says. Compress shrinks the file for email; OCR makes a scan searchable and selectable; Grayscale drops colour to save space; and Remove Metadata strips the hidden document info before you share.
Compression, OCR and grayscale run on Ream’s hardened server and the files are deleted immediately after; removing metadata happens right in your browser. Everything is free, with no sign-up.
Frequently asked questions
How much smaller can compression make my PDF?
Scanned documents often shrink by 50–80%; PDFs that are mostly typed text shrink less, because there was little image data to remove.
What does OCR do to a scan?
OCR PDF recognises the text in a scanned image so it becomes searchable and selectable, and it can straighten skewed pages.
Why convert a PDF to grayscale?
Grayscale removes colour, which can cut the file size and gives cleaner black-and-white printing.
Does removing metadata change the visible document?
No — Remove Metadata only strips hidden information such as author, software and timestamps. The pages look identical.
