Phone photos are rotation-tagged and 4–8 MB each. Converting to PDF keeps them readable and lets you compress the whole document afterwards to hit upload limits.
In practice: (1) Shoot documents flat, avoid shadows, then convert. (2) Use the compressed preset after conversion for forms with size limits. (3) HEIC photos must be converted to JPG first.
Frequently asked questions
Do you support HEIC?
Convert HEIC to JPG/PNG before uploading — browsers cannot read HEIC in an upload form.
How do I reduce photo PDFs to a few hundred KB?
Convert, then run Compress PDF with the Strong preset; photos resample efficiently.
