What is a HEIC file and why will nobody open it?
Since 2017 an iPhone saves photos as HEIC (High Efficiency Image Container) instead of JPG. The file is about half the size of a JPG at the same quality, which is great for storage and terrible the moment the photo leaves the Apple world. A Windows laptop shows a blank icon. An older Android phone says the file is unsupported. An exam portal, HR system or government form rejects the upload outright, because it wants JPG or PDF.
That is the moment people search for HEIC to PDF. A PDF is the safest format there is: it opens on every phone, laptop and printer, and it can hold several photos as pages of one document. This HEIC to PDF converter reads the iPhone file directly, so you do not need to change any camera setting, email the photo to yourself or install anything.
This HEIC to PDF maker online is free, needs no account, adds no watermark and has no limit on how many photos you convert. And because the HEIC is decoded inside your browser, the photo is never uploaded to a server.
Can I convert HEIC to PDF without changing my iPhone settings?
Yes. Many guides tell you to switch Camera settings to Most Compatible so future photos are JPG. You do not need to do that here, and it would not help with photos you have already taken. Leave the camera as it is; this page handles HEIC and HEIF files as they come off the phone, including photos taken in portrait mode and burst shots.
What happens to Live Photos?
A Live Photo is a still HEIC picture plus a short video clip. Only the still image is used; the PDF page shows the photo exactly as it appears in your library, and the movement clip is left out. If you have edited the Live Photo to use a different key frame, that key frame is what you get.
How the HEIC to PDF converter works, and why nothing is uploaded
Browsers on Windows and Android cannot read HEIC on their own, so most online converters upload your photo to a server, decode it there, and send back a PDF. This page takes a different route. The first time you add a HEIC file, it loads a small decoder (about 1 MB, built with WebAssembly) into your browser tab. From then on the decoding happens on your own device. The photo never leaves your phone or computer.
That matters for the kinds of photos people convert: a picture of a passport, a signed form, a prescription, a child's school certificate. There is no copy on any server, no expiring download link, no account attached to the file. Close the tab and nothing remains.
The one-time decoder download is why the very first conversion takes a few seconds longer. After that, converting a batch of ten photos is as fast as any other image format.
HEIC to PDF converter offline
Once the page and the decoder have loaded, no internet is used. A weak or metered connection does not slow anything down, and you could switch off Wi-Fi and still convert. If you searched for a HEIC to PDF converter download because you wanted that privacy from a desktop program, this gives you the same result without installing anything.
HEIC to PDF on iPhone and iPad, without an app
Open this page in Safari on the iPhone, tap Select image files, and choose Photo Library. Select the photos you want, tap Add, put them in order, and tap Convert to PDF. The PDF appears in the Files app under Downloads, ready to share into Mail, WhatsApp or a form's upload button. That is how you convert an iPhone photo to PDF on the phone itself, without an app, in under a minute.
Convert HEIC to PDF on iPad the same way; the larger screen makes dragging pages into order easier. If your photos live in iCloud and have not been downloaded, iOS fetches the full-resolution versions when you select them, which can take a moment on a slow connection.
People also ask about iPhone photo to PDF in Notes: the Notes app can scan a paper document into a PDF using the camera, but it cannot turn photos already in your library into a PDF, and it forces its own cropping and colour processing. For existing photos this page is the direct route; for scanning paper pages with the camera, LovePDF's Scan to PDF tool does the same job in the browser and also accepts HEIC.
How to save a HEIC to PDF and transfer it
After you tap Convert to PDF, Safari asks whether to download; tap Download and the file goes to Files, then Downloads. From there, long-press it to share, AirDrop it to a Mac, attach it to an email, or pick it from a website's upload button. The PDF is what you transfer; the original HEIC stays untouched in your library.
Best iPhone photo to PDF app: do you need one?
No. App store converters often add a watermark, limit you to a few files, or charge a subscription for batch mode, and several of them upload your photos. Add this page to your home screen from Safari's share menu and it opens like an iPhone photo to PDF app, with none of those catches.
HEIC to PDF on Windows 10, Windows 11 and PC
Windows does not open HEIC files unless you install an extension, and even then the Photos app's Print to PDF handles one image at a time. Here you skip both steps: open this page in Edge, Chrome or Firefox, drag the HEIC files from Explorer or click Select image files, and click Convert to PDF. The decoder runs in the browser, so HEIC to PDF on Windows 11 works the same as on Windows 10, and on any PC that can run a modern browser.
The usual way HEIC photos reach a PC is by cable, AirDrop to a Mac, iCloud for Windows, or an email or chat app. If a chat app already converted them to JPG on the way, that is fine too; JPG, PNG and WebP go in the same batch.
How to turn HEIC to PDF on Mac or MacBook
A Mac can preview HEIC natively, and the Preview app can export one photo as a PDF, but combining several into one document with a chosen page size means more clicks than most people want. Here is how to convert HEIC to PDF on Mac: open this page in Safari or Chrome, drag the iPhone photos in from Finder or the Photos app, and click Convert to PDF. It works the same on a MacBook, iMac or Mac mini.
How to go from HEIC to PDF on Android and Chromebook
Someone sends you an iPhone photo and your Android phone cannot open it. Save the file, open this page in Chrome, pick it with Select image files, and convert. Chromebooks work the same way. Because the decoding happens in the browser, it does not matter that the device itself has no HEIC support.
HEIC to PDF without losing quality, in the page size you need
An iPhone photo is typically 4032 by 3024 pixels. The decoder produces the full-size image and those pixels are placed in the PDF as they are, so there is no quality loss on the way. If you later need the picture back, PDF to JPG at 300 dpi returns the same detail.
Page size decides what the PDF looks like. Same size as the image makes each page exactly the shape of the photo, with no white space; it is the best choice for photos viewed on a screen. A4 or US Letter fits the photo onto a standard sheet for printing or for forms that require a fixed page size; Orientation on Automatic turns the page to match each photo. Margin adds a white border of your choice, or none.
Colour and orientation are handled too. HEIC photos carry a rotation flag, so a photo taken in portrait comes out upright rather than sideways, and wide-colour photos are converted to the standard colour space a PDF viewer expects.
HEIC to PDF small size: hitting an upload limit
A full-resolution iPhone photo makes a PDF of roughly 1 to 3 MB per page. Many portals cap uploads at 100 KB, 200 KB or 500 KB. Convert here first, then open the result in Compress PDF and type the limit in the target size field; it tries stronger settings until the file fits and shows you the final size. That pair is your HEIC to PDF converter and compressor. Page size and margin do not change the file size; only compression does.
HEIC to PDF merge: several iPhone photos in one document
Select all the photos at once and each one becomes a page of a single PDF, in the order shown in the list. That is the HEIC to PDF converter and merge feature in one step: five photos of a five-page contract become one five-page PDF. Photos are listed in the order you picked them; drag rows or use the arrows to change it before converting.
You can mix in other formats. A HEIC from the iPhone, a JPG from an Android phone and a PNG screenshot go into the same PDF. The image to PDF page covers every format together, JPG to PDF has tips for camera photos, and PNG to PDF covers screenshots.
If you already have a PDF, for example a typed cover letter, convert the photos here and then merge the PDF files into one document.
Changing HEIC to PDF one photo at a time
For a single photo, select just that one and convert; you get a one-page PDF. If you need each photo as its own PDF rather than pages of one file, convert them one at a time, or convert them together and then split the PDF into separate pages.
HEIC to PDF or JPEG: which should you choose?
Pick PDF when you are uploading to a form or portal, sending several photos as one file, printing at a fixed page size, or sharing a document that should not be edited. Pick JPEG when the destination is a photo field (a profile picture, a passport photo box) or an app that only accepts images.
LovePDF does not offer a direct HEIC file to JPG converter. If you need JPEGs, the quickest route is a HEIC to PDF to JPG detour: convert the photos to PDF here, then run the PDF through PDF to JPG, which exports every page as a JPG, PNG or WebP at the resolution you choose. On an iPhone you can also share a photo to Files and it is usually converted to JPG on the way.
Any browser or PDF app can open the result, so you do not need a special HEIC to PDF viewer. Need to write on the page, add a date or place a signature? Edit PDF lets you type and draw on any page in the browser.

Best free HEIC to PDF converter: what to look for
Whether you pick a website or a HEIC to PDF converter app, check four things: does it read HEIC without asking you to change camera settings, does it keep full resolution, can it put several photos into one PDF, and does it upload your photos. This page passes all four, and it is free online with no sign up, which is rarer than it should be.
