Convert HEIC to PDF

iPhone saves photos as HEIC by default — smaller than JPG and invisible to most browsers and printers. This turns those photos into a PDF or into JPGs without uploading them anywhere: the conversion runs in the tab you already have open.

How it works

1. Add your HEIC photosDrop HEIC, JPG, PNG or WEBP files together. HEIC files are the ones that usually arrive sideways — the grid shows each one upright before the PDF is made.
2. Check the order and the way upPages follow the order shown, so drag a photo earlier or later if it is in the wrong place. Turn any that arrived sideways with the arrows on it.
3. Create the PDFOne page per photo is created, sized to the photo itself. Or download as JPGs when you need images rather than a document.

Why iPhone photos come out as HEIC

Apple switched the default camera format to HEIC (also called HEIF) because it stores the same picture in roughly half the size of a JPG. That saving is real — a photo that would be 5 MB as JPG is about 2.5 MB as HEIC — which is why iCloud can hold twice as many.

The trade is compatibility. Chrome, Firefox, Windows Photos and many printers still cannot open HEIC, and nothing outside the Apple world expects it. Most people discover this when they try to attach a photo to an email, upload it to a portal, or print it — the file is there, it looks fine on the phone, and nothing else will take it.

How page size is decided

Each photo becomes one page, sized to the photo's own pixel dimensions measured in points (1/72 inch). Nothing is cropped and no white margin is added, so a 3000 x 4000-pixel photo becomes a page about 106 x 141 cm — the proportions are exact, just very large.

That is fine for keeping screenshots sharp and awkward for a printer that expects A4. If you need document-sized pages, resize the images first: A4 at 150 dpi is about 1240 x 1754 pixels and at 300 dpi about 2480 x 3508. Resize to one of those and the pages come out exactly A4 — and the file becomes far smaller too.

Keeping quality and fixing orientation

HEIC photos are re-encoded as high-quality JPG when they go into the PDF, through a canvas at 92% quality. That is one small, one-time conversion — not a second compression after a first — and for photographs it is visually lossless. PNG photos are still embedded as PNG with no conversion.

Orientation is read from the photo and written as the page's rotation, the same way Images to PDF handles it: a photo that looks upright on the phone comes out upright in the PDF, and the arrows on each thumbnail settle any that the file stored mirrored.
