Frequently Asked Questions
How much can a PDF usually be compressed?
It depends on the document type, but scanned and image-heavy files often show the largest reductions. Text-heavy PDFs may shrink less because they are already relatively efficient.
Will compression make my document blurry?
The tool is designed to balance file size and readability, but stronger compression can reduce image quality more noticeably, especially in scanned pages or graphics-heavy files.
When should I compress a PDF?
Compress a PDF when it is too large for email, cloud upload limits, website delivery, or quick mobile viewing.
Should I merge before or after compressing?
If you are creating one final document from several PDFs, it often makes sense to merge first and compress the finished combined file afterward.
