HEIC to PDF Converter

This HEIC to PDF converter turns iPhone and iPad photos saved as .heic into a single PDF, one photo per page, in the order you choose. It is for the everyday case of a photographed document — a receipt, an ID, a signed form, pages of notes — that has to be sent as a PDF from a computer that cannot even open HEIC files.

HEIC is the format iPhones have used for photos by default since iOS 11. It stores images with HEVC compression inside a HEIF container, which makes photos roughly half the size of JPG — but a PDF cannot contain HEVC images, so a HEIC photo can never go into a PDF as it is. Every HEIC to PDF converter has to decode the photo and store it again in a format PDF supports. This one says exactly how: each photo is decoded, drawn on a canvas at its full size (up to 16.7 megapixels), and encoded once as JPG at quality 92, then placed in the PDF. At that quality the re-encode is very hard to see, but it is one lossy step, and we would rather tell you than claim otherwise. It also makes the PDF larger than the HEIC files — often about twice the size — because JPG needs more bytes than HEVC for the same picture.

Decoding happens on your device. Chrome, Edge and Firefox cannot open HEIC at all, and Safari's own decoder returns only a file's main image, so every browser uses the same HEIC decoder (the heic2any library, about 1.3 MB), downloaded the first time you convert — that is a download of code to your browser, not an upload of your photo. It applies the photo's rotation, so portrait shots come out upright, and if one HEIC file holds several images, as some burst and edited photos do, each becomes its own page. If it cannot read a file, Safari's built-in decoder is tried, which gives the main image only.

iPhone and iPad browsers cannot draw an image larger than 16.7 megapixels (4096 × 4096). Recent iPhones take 24-megapixel photos (5712 × 4284), so any photo over that limit is drawn at the largest size that fits — 4729 × 3547 for a 24 MP photo — on every device, and the result names each photo that was reduced.

What is not carried over: the photo's EXIF metadata — capture date, camera, and GPS location — does not survive the re-encode, which is usually what you want in a document you are sending to someone. Depth maps, Live Photo motion and HDR gain maps are also dropped; the PDF holds a standard 8-bit photo.

JPG and PNG files from the same camera roll can be added too. Those are placed in the PDF without any re-encoding: JPG byte for byte, PNG losslessly.

Page size "Fit to image" makes each page the photo's own size at 96 pixels per inch, which for a 12-megapixel iPhone photo (4032 × 3024 px) is a 42 × 31.5 in page — fine on screen, awkward to print. Very large images are scaled down so no page exceeds 200 in (14,400 pt) on a side, the largest page size PDF viewers accept. For printing or submitting, choose A4 or US Letter: each photo is scaled down to fit inside the margin and centred, and "Auto" orientation gives landscape photos a landscape page.

Nothing is sent to a server: you can confirm in your browser's developer tools under Network that no request carries your photos.

1. Each file's leading bytes are read: an ISO-BMFF ftyp box with a HEIC brand (heic, heix, mif1 and related) marks a HEIC file; JPG and PNG are recognised by their own signatures. AVIF and other files are refused with a message naming what they are. 2. HEIC is decoded by heic2any, loaded only when needed, in every browser; every image in the file is decoded, with its rotation applied. If heic2any cannot read the file, the browser's own decoder is tried (Safari only), which returns the main image only. 3. Each decoded image is drawn on a canvas at full resolution — or, above 16,777,216 pixels, at the largest same-shape size under that — and encoded as JPG at quality 0.92 with canvas.toBlob. 4. JPG files are embedded unchanged; PNG files are stored losslessly. 5. Each image gets a page: Fit to image = pixels × 0.75 pt (96 DPI) plus the margin; A4 (595.28 × 841.89 pt) or Letter (612 × 792 pt), landscape when Auto and the photo is wider than tall, with the photo scaled by min(available width ÷ width, available height ÷ height, 1) and centred. 6. Pages follow the list order. One file is saved as its own name with .pdf (IMG_0042.HEIC → IMG_0042.pdf); several as images.pdf.
