Convert HEIC photos to PDF

Turn iPhone HEIC photos into a single PDF in your browser. Reorder pages, pick page size, no signup.

Files are processed entirely in your browser. Nothing is uploaded to any server.

About this tool

iPhones and iPads default to HEIC — High Efficiency Image Container — because it stores photos at roughly half the file size of JPEG with equivalent visual quality. The problem is that Windows, most web services, and many PDF workflows don't recognise the format at all. HEIC to PDF solves this by converting your iPhone photos into a universally readable PDF document right inside the browser.

You can drop a single photo or a batch of them. Once the files are loaded, drag the thumbnails to set the page order, then choose whether each page should be A4, US Letter, or fitted to the exact image dimensions. The conversion decodes the HEIC data locally using a WebAssembly library, so it works even in browsers that have no native HEIC support.

The resulting PDF is a clean document you can email, upload to any service, or print. Because no files are sent to a server, images you'd rather keep private — medical photos, legal documents, personal records — stay on your device throughout the process.

How it works

  1. 1

    Drop your HEIC photos

    Drag one or more .heic / .heif files onto the page.

  2. 2

    Reorder & size

    Drag thumbnails to reorder. Pick A4, Letter, or fit-to-image.

  3. 3

    Download PDF

    Click Make PDF to download a single document.

Frequently asked questions

Why isn't HEIC supported natively in Windows?
Most browsers can't decode HEIC. We decode it locally with a WASM library — still no upload.
Does it preserve image quality?
Yes. We embed images at full resolution; downscale is opt-in.
How many photos can I combine?
Hundreds, depending on size. Very large batches run in a Web Worker so the UI stays responsive.
Can I mix HEIC with JPG/PNG?
Yes — drop them all in. They're combined in the order you set.
Files uploaded?
No. The conversion runs entirely in your browser.
