Converting HEIC to PDF free takes one step here: drop your iPhone photos anywhere on this page. They are assembled into a single PDF in the order you dropped them, using the page size you pick above, and your photos stay completely private. No upload, no photo cap, no signup.
The two-step problem, solved in one
The usual dance: convert HEIC to JPG on one site, then combine JPGs to PDF on another. That's two uploads of your documents to two strangers' servers. This page does both steps in one private pass: current-generation HEIC decoding (iOS 18+ photos included) feeding directly into PDF assembly. Mixed batches work too. HEIC, JPG and PNG together become one document.
FAQ
What order do pages come out?
The order you drop or select the photos.
Is quality kept?
Photos are embedded at high quality (92), so text in document photos stays perfectly readable while the PDF stays email-able. Need smaller? Run the photos through compress first, then PDF them.
Are my documents private?
They never leave your device. That matters, because photos of documents are exactly the files that shouldn't tour the internet.
