Frequently asked questions
How do I reduce a PDF to 500KB?
Upload the PDF and click Compress. ADPDF tries lossless compression first, then stronger levels until the file is under 500KB.
What if my PDF stays above 500KB?
Long scanned files may not fit. Split the PDF and keep only the pages the portal needs, then compress again.
Will the text still be readable?
Yes. Stronger levels turn pages into images at a readable quality that most portals accept.
Is my document uploaded anywhere?
No. Compression runs entirely in your browser.
