Your iPhone’s photos are HEIC files by default, so when a form asks for a PDF of a photo, a signed document, an ID, a receipt, the file sitting in your Photos app usually isn’t in the right format at all. Grabio turns that HEIC straight into a PDF right on your iPhone, no app to install.

Most people don’t realize their iPhone photos are saved as HEIC until a form specifically rejects the upload for not being a PDF.

How to Convert HEIC to PDF on iPhone

This comes up constantly with photographed documents: a signed contract page, a receipt for an expense report, an ID photo for a portal that only accepts PDF uploads. The photo itself is fine, it just needs to be wrapped into a PDF first.

Convert HEIC to PDF on iPhone: FAQ

Can I combine several HEIC photos into one PDF?

Grabio’s Photo to PDF option works on one photo at a time. If you need multiple photos combined into a single multi-page PDF, convert each one first, then use Grabio’s merge PDF option to combine them into one file.

Will the PDF still look sharp?

Yes, the PDF keeps your photo’s original resolution, it’s simply wrapped in a PDF container rather than re-compressed.

Do I need to convert the HEIC to JPG first?

No, Grabio’s Photo to PDF action reads the HEIC file directly and produces the PDF in one step, there’s no need for a separate conversion first.
