Frequently Asked Questions
Will compressing my PDF reduce text readability?
No. Vector text elements, TrueType glyphs, and mathematical paths remain uncompromised. Compression focuses on optimizing raster streams, metadata caches, and internal structural dictionaries.
Can I compress password-protected PDF documents?
You must first unlock the PDF using our Unlock tool, then compress the document and optionally re-lock it.
Is there an artificial file size limit?
No arbitrary limits are imposed. The only limit is the available RAM memory on your computer or phone.
