How to convert HEIC to PDF — free, on Windows, without uploading your photos
Updated
HEIC is the compact photo format iPhones use by default, and it's awkward to share with anyone outside Apple's world. This tool decodes your .heic photos and lays them into a single PDF — one photo per page — entirely in your browser. No upload, no signup, and you can reorder pages and pick a page size before saving.
When a PDF beats individual images
Converting iPhone photos to JPG is the right move when you want editable image files. But a lot of the time what you actually need is a single, tidy document: a set of receipts for an expense claim, pages of a contract you photographed, a child's artwork to email to grandparents, or images that have to arrive in a specific order. For all of those, a PDF is the better container — it holds many photos in one file, preserves their order, and opens identically on every device and in every email client without anyone needing a HEIC codec.
This tool takes one or many .heic files and lays them into a PDF, one photo per page, in the order you choose. Because HEIC is an Apple-default format that Windows and older software often can't read, doing the conversion and the PDF assembly in one local step saves you a two-hop dance through some other converter.
Convert HEIC photos to a PDF in three steps
- Drop your .heic photos into the box at the top (or click to browse). Add as many as you need — each becomes one page.
- Set the order and layout. Drag the tiles to reorder pages. Choose "Fit to photo" for borderless pages sized to each image, or A4 / Letter / Legal with a margin for a standard printable look.
- Click Build PDF. Each photo is decoded and placed into the document, and a single PDF downloads. That's it.
No account, no watermark, no page cap. Everything happens on your machine, so the practical limit is just your device's memory.
Your photos stay on your device
The photos people turn into PDFs are often exactly the sensitive kind — scanned IDs, bank letters, medical forms, signed contracts. Uploading those to an anonymous "free converter" means handing the originals, GPS metadata and all, to a server you can't see. This tool doesn't do that.
The HEIC files are decoded in your browser by a WebAssembly build of the open-source libheif library, assembled into a PDF with SwissArmyPDF's local PDF engine, and delivered to you as a download. Nothing is transmitted; close the tab and it's all gone. The only record kept is an anonymous counter noting that the tool ran — never anything from your files.
Getting the best result
- Order matters for documents. If you photographed a multi-page contract, drag the tiles so the pages run 1, 2, 3 before building — the PDF follows the tile order exactly.
- "Fit to photo" vs a paper size. Fit-to-photo gives borderless pages that match each image's shape — best for a photo album feel. A4/Letter with a margin is better if the PDF will be printed on standard paper.
- iCloud downloads. If a photo came via iCloud and hasn't finished downloading, it can be an empty placeholder — make sure it's fully on your device first.
- Big batches. Hundreds of full-resolution photos at once use a lot of RAM. On an older phone or laptop, build in groups and merge the PDFs afterward.
