Frequently asked questions
How do I reduce a PDF to 300 KB?
Drop it here and press Compress. Each page is redrawn at the highest quality that keeps the whole file under 300 KB. Scanned documents usually shrink the most.
Will the text stay selectable?
No. To get large savings, pages are saved as optimised images. That's ideal for certificates and ID proofs; keep your original if you need to copy text.
Is my PDF uploaded?
No. The PDF is read and rebuilt inside your browser. Nothing is sent to a server.
