Frequently Asked Questions
Can I compress a PDF to 500KB?
Yes. Using our high compression setting, most PDFs can be reduced to 500KB or smaller. The amount of reduction depends on the original content — documents with many images see the most dramatic shrinkage.
What types of PDFs compress best to 500KB?
Image-heavy PDFs and scanned documents compress most effectively. Text-only PDFs are already quite small and may already be under 500KB.
Will text in my PDF remain readable at 500KB?
Yes. Text content is preserved perfectly. Only embedded images are re-encoded at lower quality. The text remains sharp and fully searchable.
Is there a limit on how many PDFs I can compress?
No. You can compress as many PDFs as you need, one at a time. There are no daily limits or account requirements.
