HEIC to PDF converter
Most people converting HEIC to PDF are not making a photo album — they are sending a photographed document to somewhere that only accepts PDF. This tool is built for that case.

Why this conversion keeps coming up
Landlords, universities, HR departments, tax portals and insurance claims all tend to accept exactly one file type: PDF. Meanwhile the easiest way to capture a signed form or a receipt is to photograph it with a phone, which produces HEIC. The gap between those two facts is why this page exists.
Everything runs locally, which matters more than usual here. A photographed document is often a passport page, a bank statement or a payslip — the last category of file you want passing through an anonymous upload form.
Getting a document photo that reads well
- Shoot square-on, in even light
Standing over the page with the phone parallel to it avoids the keystone distortion that makes text look drunk. Diffuse daylight beats a ceiling light directly overhead, which throws your own shadow across the page.
- Fill the frame with the page
Cropping in the Photos app before converting means more of your pixels are spent on the text and less on your desk. It also produces a much smaller PDF.
- Leave the size setting on Original
Downscaling is the fastest way to make small print unreadable. Only cap the size if the recipient has an upload limit you are hitting.
- Check the result before sending
Open the PDF and zoom to 100%. If you cannot comfortably read the smallest line of text, neither can the person processing your application.
Do you need a real scan instead? If the document has to be flat, straight and high contrast, the iPhone's built-in scanner does a better job than any converter. Open Notes, create a note, tap the camera icon and choose Scan Documents. It corrects perspective, removes shadows and exports straight to PDF — skipping HEIC entirely.
One PDF per photo, or one PDF for everything?
This tool writes one PDF per image, which is what you want when each file is a separate receipt. For a multi-page document — a six-page contract photographed page by page — convert them all, then merge. On a Mac, open the first PDF in Preview, show the sidebar with ⌘+⌥+2, and drag the others in. On Windows, Microsoft Edge can print several PDFs into one, or use any offline merge utility. Merging in the browser is possible but requires holding every page in memory at once, which falls over on large batches.
Keeping the file small enough to email
Photos are large and mail servers are fussy — 10 MB is a common attachment ceiling and 25 MB is usually the maximum anywhere. A single full-resolution page lands around 2–4 MB. If a batch pushes past the limit, cap the size at 2000 px, which is still well above the 150–200 DPI that document scanning normally targets.
Common questions
- Can I combine several HEIC photos into one PDF?
- This tool creates one PDF per photo. To merge them, convert them all and then combine the results in Preview on macOS, Edge on Windows, or any offline PDF merge tool. Merging in the browser needs every page in memory simultaneously, which is unreliable for large batches.
- What page size does the PDF use?
- A4, with the image scaled to fit and centred, keeping its aspect ratio. Portrait photos produce portrait pages and landscape photos produce landscape pages, so nothing is rotated unexpectedly.
- Is the text in my PDF searchable?
- No. The PDF contains a photograph of text, not text itself. Making it searchable requires OCR, which is a separate step — Adobe Acrobat, macOS Preview's text recognition, or Google Drive's built-in OCR when you open the file with Google Docs.
- Are my documents uploaded anywhere?
- No. The image is decoded and the PDF is assembled entirely inside your browser tab. This matters particularly here, since photographed documents are usually personal or financial.
