How to convert HEIC to PDF
HEIC to PDF turns HEIC and HEIF photos — the format iPhones and iPads use when the camera is set to High Efficiency — into one PDF, with one photo per page in the order you see on screen. It runs in your browser: the photos are read on your device and are not uploaded.
1. Add your photos
Tap Add HEIC photos and choose one or more files. You can add more whenever you like; each new batch goes to the end of the list. On a computer you can also drop files onto the page.
The app checks what each file really is, not what it is called. Photos named .heic, .heif, .HEIC or .hif open, and so does a real HEIC that ended up with a .jpg name. A JPG, PNG or WebP image is turned away on its card, with a link to the app made for it: JPG to PDF, PNG to PDF or, for other formats and mixed sets, Image to PDF. On iPhone and iPad, where the photo library can hand over a HEIC as a JPG, a JPG gets a card that lets you continue with it or pick the original HEIC from Files; iPhone photos to PDF explains why. HEIC vs HEIF explains which files count as HEIC.
2. Let the photos open
Safari can read HEIC by itself. Chrome, Edge and Firefox can’t, so there the app downloads a HEIC decoder — about 0.5 MB — when you add your first HEIC, and not before. The decoder works in the background, so the page doesn’t freeze while photos open.
On a desktop computer with an Apple M-series chip, a 12-megapixel iPhone-style photo took about 0.8 seconds to open in Chrome and 0.2 seconds in Safari’s engine. Phones are slower, and we have not timed this on a real iPhone.
If a file is damaged or cut off, its card says it couldn’t be opened and offers Try again and Remove. It never becomes a blank page, and your other photos keep working.
3. Order and turn the photos
The number on each card is its page number in the PDF. Drag a card to move it — on a touch screen, press and hold it first — or use the card’s More menu. Combining HEIC photos into one PDF covers sorting a long list.
An iPhone photo records which way is up, and the app applies that once, so most photos already stand upright on their cards. If one still lies on its side, tap Rotate 90° clockwise on its card, once for each quarter turn.
4. Choose the page
Page setup in the toolbar sets the page for the whole PDF: A4 or Letter, with orientation and margin, or Fit to image, where every page takes its photo’s shape with no margin. On A4 and Letter each photo is scaled to fit and centred; it is never cropped or stretched. The same panel holds the quality choice, Quality first or Smaller file.
5. Save the PDF
Tap Save PDF. The PDF is made and handed to your browser in one step, and Cancel stops the work, including a photo that is still opening. When it’s done, the strip at the bottom shows the number of pages and the real file size. If your browser doesn’t start the download by itself, use Download PDF. Download again gives you the same file once more without rebuilding it. Share appears only where your browser can share files, and closing the share sheet without choosing anything is not an error. On iPhone and iPad the button says Prepare PDF instead: the PDF waits in the strip, with Save or share to send it to Files or another app and Open PDF to view it.
What happens to each photo
A PDF can’t hold HEVC, the compression inside a HEIC file, so every photo is encoded again and stored as a high-quality JPG. JPG is a lossy format and less efficient than HEVC, which is why a PDF of HEIC photos is usually larger than the photos themselves: with Quality first, a 1.1 MB, 12-megapixel photo made a 1.9 MB PDF in Chrome and a 2.6 MB PDF in Safari’s engine.
Wide-colour iPhone photos are converted to standard sRGB colours on the way. Orientation, colour and quality explains what that changes and when Smaller file helps.
Location, dates, camera details and file names from your photos are not written into the PDF.
