HEIC to PDF Converter
This free HEIC to PDF converter turns iPhone HEIC photos into a proper PDF — one photo per page, in your order — entirely in your browser. Add one photo or a whole set: mark sheets photographed on a phone, receipts, ID proofs. Your photos are never uploaded, which matters for pictures this personal: the conversion happens on your own device.
Nothing leaves your device. Your photos are converted locally in your browser. The heic2any conversion library loads from the jsDelivr CDN (cdn.jsdelivr.net) because browsers cannot read HEIC on their own — only the library travels over the internet, never your photos. HEIC decoding is heavy work: a large photo can take several seconds, and converting many at once is slower still.
How to use this converter
- Click the drop box (or drag your HEIC photos onto it). The box confirms how many photos you chose and their total size.
- Check the list — remove any photo you added by mistake with its ✕ button.
- Choose the page size and margins, and set the output file name.
- Press Convert to PDF. Each photo shows its status as it converts — HEIC decoding takes a few seconds per photo.
- Press Download .pdf to save the finished document.
How it works
HEIC (High Efficiency Image Coding) is the format iPhones and iPads save photos in by default. It squeezes a photo into roughly half the bytes of a JPEG at the same quality — a real saving on a phone — but it has one big drawback: outside Apple's own apps, support is patchy. Windows needs extra codecs, many websites refuse HEIC uploads, and a PDF, which every device on earth can open, is usually the safest way to send the photos on. That is the gap this converter fills.
Browsers cannot decode HEIC by themselves, so the page loads heic2any, an open-source converter library, from the jsDelivr CDN. For every photo you add, heic2any decodes the HEIC data into an ordinary JPEG image inside your browser tab. The tool then takes each decoded photo, works out whether it is taller or wider, turns the PDF page to match, and fits the photo inside the page with your chosen margin:
The pages are assembled by the jsPDF library stored on this website, one photo per page, and the finished PDF downloads straight from your browser. No photo is uploaded at any point — the only network traffic is the one-time download of the converter library itself.
| Situation | What to expect |
|---|---|
| Ordinary iPhone photos (.heic) | Convert cleanly, full quality |
| Several photos at once | One PDF, one photo per page, in your order |
| Very large photos (48 MP) | Convert, but allow several seconds each |
| Some multi-photo sequences / depth variants | May fail — the tool names the file; the rest still convert |
| Files that are really JPEGs renamed to .heic | Rejected with a clear message |
Two practical notes. First, speed: HEIC decoding is genuinely heavy arithmetic, done here by your own device, so patience is part of the bargain — converting twenty large photos can take a minute or two, and the status list shows progress photo by photo. Second, honesty about failures: a small minority of HEIC files use features the converter library cannot yet read. When that happens the tool tells you exactly which file failed and still builds the PDF from the others, and the FAQ below gives the standard workaround — export that one photo as JPEG from the Photos app and add the JPEG to a PDF with our PNG to PDF-style image tools.
Worked example
A father photographs his daughter's three documents for a school admission form — aadhaar card, birth certificate and a passport photo page — on his iPhone, and the school's portal accepts only a single PDF.
Step 1: He AirDrops the three HEIC photos to his laptop and drops them into the box. The tool confirms: ✓ Chosen: 3 photos.
Step 2: He keeps the defaults — A4 pages, narrow margins — and presses Convert to PDF.
Step 3: The list ticks through the three photos: converted, converted, converted.
Step 4: He presses Download .pdf and saves heic-to-pdf.pdf.
The result is one 3-page PDF — one document per page, the right way up, sharp enough to print — uploaded to the portal without a single photo leaving his laptop for a stranger's server.
FAQ
Are my photos uploaded to a server?
No. Your HEIC photos are converted and packed into a PDF entirely in your browser — personal photos never leave your phone or computer. The heic2any conversion library is loaded from the jsDelivr CDN because browsers cannot read HEIC on their own; only that library travels over the internet, never your photos.
What is a HEIC file?
HEIC is the photo format iPhones and iPads have used by default since iOS 11. It stores high-quality photos in about half the space of JPEG, which is why Apple chose it — but many Windows PCs, websites and upload forms still cannot open it. Converting HEIC photos to a PDF (or to JPEG first) is the standard way to share them with everyone.
Can I convert several HEIC photos into one PDF?
Yes — that is the main job of this tool. Add as many HEIC photos as you like and they become one PDF, one photo per page, in the order you added them. It is the quickest way to turn a set of phone photos — documents, receipts, ID proofs — into a single file you can send or upload.
Why did one of my photos fail to convert?
Most ordinary HEIC photos convert fine. Failures usually involve unusual variants — for example some multi-photo sequences, depth-photo editions, or files from newer cameras with features the converter library does not yet understand. The tool names the file that failed and still builds the PDF from the rest. For a failed file, opening it in the Apple Photos app and exporting it as JPEG, then converting that, is a reliable workaround.
Will the PDF keep my photos' quality?
Each photo is decoded at its full resolution and placed on its PDF page at 92% JPEG quality, which is visually identical for photographs. The page turns landscape automatically for wide photos, and portrait for tall ones, so phone photos in either hand position come out the right way up and properly fitted.
