One photo or a whole document — in one PDF
PDF is the universal “send it and it looks the same everywhere” format, which is why it’s the natural choice for documents you capture with your phone: receipts, contracts, handwritten notes, ID copies, or a few related pictures you want to keep together. SnapHEIC takes the HEIC photos straight off your iPhone and assembles them into a single, multi-page PDF — each photo becomes one page, in the order you add them.
Built in your browser — unlike the big PDF sites
Here’s the key difference from tools like iLovePDF, Smallpdf or Adobe: those services upload your files to their servers to do the work. When your photos are a passport, a bank statement, or a signed agreement, that’s exactly what you don’t want. SnapHEIC decodes every HEIC and builds the PDF entirely on your device using WebAssembly and an in-browser PDF engine. Your files are never uploaded, there’s no sign-up, and there’s no watermark stamped on the output. You can confirm nothing is sent anywhere by opening your browser’s DevTools → Network tab while you build the PDF, or simply by switching on airplane mode first.
| SnapHEIC | Most online PDF converters | |
|---|---|---|
| Files uploaded to a server | No — stays on your device | Yes |
| Sign-up / account | No | Often required |
| Watermark on output | No | Sometimes (free tiers) |
| File / page limits | No server limit | Common on free tiers |
| Cost | Free | Free tier, then paid |
How the conversion works
Your iPhone saves photos as HEIC — a container built on the HEVC codec that Apple has used by default since iOS 11. When you drop HEIC files in here, each one is decoded in memory and drawn at full resolution, then embedded into a PDF page sized to fit it. (If a photo is a Live Photo, only the still frame is used — the PDF is a document, not a video.) The pages are stitched together and saved as one file that downloads straight to your device. Because the images are re-encoded during the process, EXIF metadata such as GPS location is removed — so the PDF you email won’t quietly reveal where each photo was taken.
Will it look good when printed?
Yes. Each photo is embedded at its full original resolution with no downscaling, so the PDF prints as sharply as the source allows. A standard 12-megapixel iPhone photo (about 4032×3024 pixels) prints crisply at letter or A4 size — comfortably above the ~300 DPI that looks clean on paper. In other words, print quality is limited only by your original photo, never by the converter.
Common uses
- Expense reports: snap several receipts, combine into one PDF to submit.
- Document scanning: photograph each page, then merge into a single PDF.
- Applications & forms: bundle ID photos and supporting images together.
- Sharing a set of pictures: one attachment instead of a dozen image files.
