Optimize PDF Tools — Smaller Files That Still Open
Two things go wrong with PDFs more than anything else: they're too big to send, or they stop opening. Both have practical fixes that don't require replacing the document.
Compression targets the real weight — embedded photographs — while leaving text and line art untouched, so the file gets smaller without looking worse. Repair rebuilds a damaged file's internal structure and salvages every page it can still read.

| Use this | When it is the right choice |
|---|---|
| Compress PDF | Email or a portal rejects the file, or scanned pages make the document far heavier than it needs to be. |
| Repair PDF | A download was interrupted, or the viewer reports the file as damaged or unreadable. |
| PDF Analyzer | You want to know which pages or images are responsible for the file's size before compressing. |
Frequently asked questions
How small can a PDF get?
It depends on what's inside. Image-heavy scans routinely shrink by 60-90%. Text-only documents are already efficient and change little, because there's no waste to remove.
Can repair recover a partially downloaded PDF?
Often yes. Pages that made it into the file are usually readable even when the index is broken, and repair rebuilds a fresh document from them.
Does compressing break links or forms?
No. Links, annotations and form fields are part of the page content and are preserved; compression only re-encodes large images.
