Frequently asked questions
Will my PDF definitely reach 50 KB?
Only very small, text-only PDFs can get that small. A page with images, color or scans will stay larger. The tool shows you the actual result so you can see if it's close enough.
Does compression affect how text looks?
Yes. Each page gets re-rendered as an image, so text is no longer selectable or searchable. This trade-off is what makes heavy compression possible.
What if my file gets bigger after compression?
If a PDF is already well-optimized, the tool keeps the original unchanged and tells you it couldn't improve it.
How large a file can I compress?
Files up to 100 MB are accepted, with a limit of 5 files at once.
