Turn iPhone photos into a PDF document
HEIC to PDF conversion is what you need when a website, an employer or a landlord asks for “a PDF” and all you have are photos taken with your iPhone. Phone cameras have replaced the scanner for most people: receipts for an expense report, a signed contract, a passport page, proof of address. The problem is that these photos are saved as HEIC, and many upload forms accept only PDF – often just a single file.
This converter turns your HEIC photos into a clean PDF directly in your browser. Nothing is uploaded: the photos are decoded on your own device with a WebAssembly build of the open-source libheif library, and the PDF is assembled locally. That matters when the pages contain personal data such as ID numbers, salary details or bank information.
Merge several photos into one PDF
The default setting, “All photos in one PDF”, puts every photo you add on its own page of a single document. Typical uses:
- Receipts and expense reports – photograph each receipt and send one tidy PDF to accounting.
- Rental and job applications – combine ID, payslips and references into one attachment.
- Multi-page forms and contracts – photograph each page and submit them as a single document.
- School and university paperwork – certificates, transcripts or handwritten assignments.
If you need each photo as a separate document instead, switch to “One PDF per photo” and every photo becomes its own PDF file.
A4 or fit to photo: choosing the page size
| Page size | What it does | Best for |
|---|---|---|
| Fit to photo | Each page has exactly the size and shape of the photo, no margins | Viewing on screen, portfolios, photo collections |
| A4 | The photo is placed on a standard A4 page | Printing, official submissions, office workflows |
As a rule of thumb: if someone will print the document or file it with other paperwork, choose A4. If it will only be viewed on a phone or computer, “Fit to photo” looks cleaner.
Converting HEIC to PDF on iPhone, Android and computer
On a computer (Windows, Mac, Linux, ChromeOS): drag your HEIC files onto the drop zone or use “Choose photos”. Pick PDF, choose your layout and click “Download PDF”.
On iPhone or iPad: tap “Choose photos” and select the pictures from your Photos library or the Files app. The finished PDF lands in Files › Downloads, ready to attach to a mail or upload to a portal.
On Android: if you received HEIC photos from an iPhone user, choose them with the file picker and convert them the same way.
The converter also accepts JPG, PNG, WebP, AVIF, GIF and BMP, so you can mix HEIC photos with screenshots or older JPG scans in the same PDF – a simple way of converting JPG to PDF as well.
Quality and file size
Each photo is first converted to a high-quality JPG and then embedded in the PDF without any additional re-compression. Text on receipts and printed forms stays readable, and full resolution is kept. If an upload form has a strict size limit, lower the JPG quality slider (range 50–100, default 92) before creating the PDF; for most documents a value around 80 is still perfectly legible.
Tip: photograph documents in good daylight, flat on a dark surface and straight from above. The cleaner the photo, the better the PDF looks – no matter which settings you choose.
Need another format?
A PDF is ideal for documents, but not for photos you want to edit or share in a chat. For that, use the HEIC to JPG converter or, for lossless editing, HEIC to PNG. Got a whole folder of HEIC images? Our guide to batch conversion explains how to handle hundreds of files at once.
