HEIC To PDFTurn A HEIC Photo Into A Text-Searchable PDF
HEIC To PDF creates exactly one PDF page per converted photo.
Drop the HEIC photo destined for OCR into the upload field first.
Save the resulting single-page PDF file to your device before adding a text layer separately in another application.
Adding a Text Layer for Search
Open a separate OCR application.
Feed the downloaded PDF into it.
Nothing reloads when the reset control is used; the current upload simply clears, leaving the page ready to prepare another HEIC for OCR.
Checking the Final Document

Count the pages in the downloaded PDF.
Continue with HEIC to PDF Quality or Convert HEIC to PDF on iPhone.
