An insurance form, an expense report, or a school portal asks for "one PDF with all your photos." Drop your iPhone HEIC files in — get back a single multi-page PDF (one image per page), or a separate PDF per photo if that's what you need. Conversion happens in your browser; nothing is uploaded.
PDF isn't just "another image format." It's the format the world uses to bundle a stack of photos into one paginated document — and that's exactly the job HEIC can't do on its own.
Insurance claims, mortgage applications, school enrollments, expense reports, government forms — almost all of them ask for "one PDF" containing receipts, IDs, photos of damage, or supporting evidence. Sending twelve HEICs as separate attachments either gets bounced or makes the reviewer hate you.
Unlike JPG (trivial to edit and re-save), a PDF carries a clear audit trail. Once you've submitted it, the recipient sees exactly the pages you submitted, in order, with timestamps embedded by their system. For anything that might end up in a dispute or audit, that matters.
Drop 1.heic, 2.heic, 3.heic in that order; you get a PDF with page 1 / page 2 / page 3 in that order. No random naming, no "sort by upload time vs. file name" guesswork at the receiving end.
iOS Files app print-to-PDF, macOS Preview, Adobe Acrobat, an online combiner, or this in-browser tool. Same goal — one PDF — but very different costs.
| Method | Install Needed | Bulk Support | Speed | Privacy | Ease of Use | Best For |
|---|---|---|---|---|---|---|
iOS Files → Print → Save as PDF | Built-in (iPhone only) | Yes (multi-select) | Fine for small batches | Local | Many taps, easy to mis-order | 10 photos straight off the iPhone |
macOS Preview → Print → Save as PDF | Built-in (Mac only) | Yes (open all, then print) | Slow on large batches | Local | Moderate — relies on Print dialog tricks | A few photos already on a Mac |
Adobe Acrobat "Combine Files" | Yes (paid subscription) | Yes | Fast once installed | Local with cloud fallback | Heavyweight for one-off jobs | Pros who already have Acrobat |
Upload-based online PDF combiners | No | Sometimes — daily caps common | Bottlenecked by upload speed | Files sent to a third-party server | Easy | One-off, non-sensitive batches |
This browser-based converterRecommended | No | Yes + combine into one PDF, no daily cap | Runs on your CPU — scales with your machine | Files never leave your device | Drop, choose page size, download | Anyone with sensitive submissions (insurance, ID, finance) |
About size: PDF embeds each photo as a JPG inside the document, so the quality slider you see in Advanced Settings controls how small each page gets. Default quality 90 plus the 2048 px Max-dimension cap typically lands a 30-photo combined PDF in the 8–15 MB range — well under most inbox and form-upload limits.
Three steps. Three decisions you might want to make in Advanced Settings — combine on/off, page size, orientation. Default settings are right for ~95% of submissions.
Drag-and-drop one photo or up to a hundred. The order you drop them is the order they appear as pages in the final PDF. The picker also accepts .heif — same format, different extension — and decodes it identically.
Default is one combined PDF, fit-to-image (no margins), auto orientation per page. For paper-printable submissions, switch Page size to A4 or US Letter. For one-PDF-per-image (rare), uncheck "Combine all pages into one PDF" in Advanced Settings.
Combined mode produces one .pdf file named heic-to-pdf-{timestamp}.pdf. Per-file mode produces a ZIP containing IMG_1234.pdf, IMG_1235.pdf, and so on, each preserving the original filename.

Built for real submission workflows: 30 receipt photos for a quarterly expense report, 20 inspection photos for a property claim, 15 identity documents for a visa file. Drop the batch, walk away, download one PDF.
Conversion uses your browser's CPU and memory. 50 HEIC photos become 50 PDF pages without ever leaving your machine — no upload progress bar, no "server timed out, please try again" after eight minutes of waiting.
iPhone photos at full 4032×3024 produce PDFs around 1.2 MB per page — a 50-page submission would land at 60 MB and bounce off most email systems and many web upload forms. We default to 2048 px on the long side here (still beautiful at viewing size) so a typical 30-photo PDF stays well under 25 MB.
Some online tools cap combined-PDF generation at 5 or 10 pages, then ask you to upgrade. Here it's just a checkbox: 100 HEIC photos in, one 100-page PDF out, no daily limit, no signup, no watermark stamped on every page.
Yes — that's the default mode. Drop multiple HEIC files in, leave "Combine all pages into one PDF" checked, and download a single multi-page PDF. The order of pages matches the order you dropped the files in. If you need separate PDFs (one per HEIC), uncheck the combine option in Advanced Settings; the result will arrive as a ZIP with one .pdf per image.
Default "Fit to image" gives you a PDF where each page is exactly the photo's aspect ratio with no margins. That's the right answer if the recipient is a web form or an internal review system. Pick A4 if you're in Europe / most of the world and the document might be printed on paper; pick US Letter for the United States. Both add a small white margin and center the photo.
On default "Auto" each page picks its orientation per image — landscape photos get landscape pages, portrait photos get portrait pages. If you specifically need every page in the same orientation (for a report that's strictly portrait, for example), pick Portrait or Landscape and every page will use that — landscape photos may letterbox into a portrait page.
Two reasons. First, this page caps the Max-dimension at 2048 px on the long side by default, which loses no visible quality at PDF viewing sizes. Second, photos inside a PDF are JPG-compressed at quality 90 — visually indistinguishable from the source for any photograph. If you need print-grade resolution, raise Max-dimension to Original and Quality to 95 in Advanced Settings.
Not in this tool. Adding a password in the browser is technically possible but it's a meaningfully different feature with security implications — easy to do wrong. If you need encryption, generate the PDF here, then run it through a desktop tool you trust (Preview's password export on Mac, or Acrobat) to add the password. We'd rather omit a feature than ship a misleading one.
PDF doesn't carry standard EXIF blocks the way JPG does, so the kind of metadata that identifies a specific iPhone, GPS coordinates, or shutter speed is dropped during conversion. The PDF only contains the visible pixels — what you see is what you'd send. For privacy-sensitive submissions, that's a feature, not a bug.
Yes — universally. PDF (ISO 32000) has been the world's portable document standard since 1993. macOS Preview, Windows Edge / Adobe Reader, iPhone Files / Mail, Android Drive / Adobe Reader — all open the PDFs this tool produces without any conversion. That's the whole point of using PDF as your delivery format.
Both. HEIC and HEIF share the same container and the same HEVC encoding — HEIC is just Apple's brand name for HEIF images. This tool decodes .heic and .heif identically and produces the same PDF output either way.
The conversion runs entirely inside your browser using JavaScript, WebAssembly, and the bundled jsPDF library. Nothing is uploaded to HeicToPng or any third party — you can disconnect WiFi after the page loads and keep converting offline. For documents containing IDs, financial records, medical photos, or anything else you wouldn't email a stranger, that's the only sensible default.
Drop your iPhone photos in. One combined PDF, downloaded in seconds.
