HEIC to PDF
Turn iPhone HEIC photos, with JPGs or PNGs mixed in if you like, into one PDF or a PDF per photo. Nothing is uploaded.

Photos are decoded and the PDF is built on your device. Nothing is uploaded.
A 12-megapixel phone photo is 4032 × 3024 px. For documents and email, 2000 px keeps the PDF several times smaller and still prints sharply at A4.

Frequently asked questions
How do I convert HEIC photos to PDF on Windows or a PC?
Open this page in Chrome, Edge or Firefox, drop the HEIC files in and press Convert. Windows can’t open HEIC files without an extra codec from the Microsoft Store, but that doesn’t matter here: the page decodes the photos itself with a WebAssembly build of libheif, so nothing needs installing and the PDF opens anywhere.
Can I combine several HEIC photos into one PDF?
Yes. Add as many as you like, arrange them with the arrows, and choose One PDF, a page per photo. The pages follow the order in the list. If you need them apart instead, choose A separate PDF for each photo and download them one at a time or as a ZIP.
Which page size and orientation should I choose?
For documents, forms and anything that may be printed, use A4 (or US Letter in the US and Canada) with Automatic orientation: each page turns landscape for a landscape photo, so the image fills as much of the page as it can without being cropped or stretched. Fit to image makes every page exactly the photo’s size, with no white border unless you add a margin; at 1 pixel per point, a 12-megapixel photo gives a page about 56 × 42 inches, which viewers and printers scale down to fit.
Why is my PDF so large, and how do I make it smaller?
A PDF of photos is about the size of the images inside it, and HEIC is roughly twice as efficient as the JPEG images a PDF holds, so expect the PDF to be larger than the HEIC files. To cut it down, set Image size to 2000 px and Image quality to Medium; for ten phone photos that typically takes the PDF from tens of megabytes to a few, while text and detail stay sharp on screen and on A4 paper.
Will the quality or orientation of my photos change?
Photos stay upright: the rotation stored by the camera is applied before the page is made, for HEIC and for JPG. At High quality the re-compression is not visible in normal photos. Choose Original to keep JPG and PNG data exactly as it is where possible; a HEIC is always decoded first, because PDF can’t hold HEIC images, and is stored as a 95% quality JPEG.
Are my photos uploaded?
No. Decoding, resizing and building the PDF all happen in your browser. The HEIC decoder, about 3 MB, is downloaded once when you add your first HEIC photo; your photos and the finished PDF never leave your device.
About this tool
iPhones save photos as HEIC, a format that takes about half the space of JPEG but that plenty of software won’t open, and no browser except Safari can display. When a form, a school or an office asks for a PDF, those photos need converting. This tool takes a batch of HEIC or HEIF files, decodes them on your device and puts them into a PDF, either all together with one photo per page or as a separate PDF for each photo.
You control how the pages look. A4 and US Letter pages hold the photo scaled to fit inside the margins, centred and never cropped, and Automatic orientation turns each page to match its photo. Fit to image makes each page the exact shape of the photo, which suits a portfolio or photo album. Margins run from none to one inch, and a live page preview next to every photo shows the result before you convert.
Mixed batches work too: JPG, PNG and WebP images can sit between the HEIC photos, which is handy when some pictures came from another phone or a scanner. Rotation stored by the camera is applied, so nothing ends up sideways. Photos are decoded one at a time to keep memory use low on phones, and a file that can’t be read, such as some Live Photo sequences, is flagged by name instead of stopping the rest.
The size settings matter for photos. At full resolution each 12-megapixel photo adds a few megabytes to the PDF; setting the image size to 2000 pixels and the quality to Medium typically makes the PDF several times smaller while it still prints sharply on A4. Everything runs in your browser with a WebAssembly build of libheif and the pdf-lib library, so your photos are never uploaded.
