About Compress PDF

Large PDFs fail email limits and slow down form uploads. Compress PDF recompresses pages so the file gets smaller while staying readable for typical office and school use.

Photo-heavy scans shrink the most. Text-heavy PDFs may shrink less—that is expected. Always preview before you send the smaller file.

Compress PDF targets megabyte limits when the page set is already correct. It is not a substitute for deleting irrelevant pages—split first if half the file is unused.

Scanned image PDFs shrink more dramatically than text-heavy born-digital PDFs. Always preview sharpness of stamps, signatures, and small type after compression.

Practical tips

If one page is huge, it is usually a high-resolution scan—compress that source scan first when possible.
Compare readability of fine print after compression.
Merge first, then compress once, to avoid repeated quality loss.
Keep the original file until the recipient confirms the compressed copy is fine.
If one page is the problem, fix that scan (resize/compress image) and rebuild.
Keep an uncompressed master for your records.
