Questions
Are my files uploaded?
No. The page loads its code once, then reads and processes your files inside the browser tab. Nothing is sent to a server; you can confirm it in your browser's network panel while a file is processed.
Why can't I upload HEIC photos to a form?
Most portals accept only JPG, PNG or PDF. Converting the photos to one PDF here solves that for document uploads; use HEIC to JPG if the form wants images.
Can I do this on the iPhone itself?
Yes. Open this page in Safari, tap the box and choose photos. Safari may hand the page JPGs instead of HEIC; the result is the same PDF.
Will the PDF be small enough to upload?
Each page keeps the photo at near full quality, so a 12 MP photo makes a page of a few megabytes. If the form has a limit, use Image to PDF under a size limit instead.
