How to reduce a PDF's size for an online form

A simple way to get certificates and documents under the size an online form asks for, on your phone, without uploading them anywhere.

Scan documents, ID cards, books and receipts with your phone camera into clean PDFs. Tips for light, angle and file size.

Turn scanned pages into an editable Word document with OCR, and get the best results with clear scans.
