Frequently Asked Questions

How much can it shrink my file?
It depends on the PDF content; image-heavy PDFs typically shrink more.
Does text quality degrade?
No, compression primarily optimizes the file structure and doesn't affect text quality.
Will this significantly shrink a PDF full of photos?
Not dramatically — the tool optimizes the file's internal structure and strips unnecessary metadata rather than recompressing images. For PDFs made bloated mainly by large embedded photos, expect a modest size reduction.
Is any of my PDF's content changed?
No — every page, image and piece of text stays exactly as it was. Only the underlying file structure is optimized.
Is there a file size limit for compression?
There's no limit enforced by the tool itself. Since compression happens in your browser, the practical limit is your device's available memory.
