Convert HEIC to PDF — turn iPhone photos into a document
Drop a HEIC photo below and get a single-page PDF at the photo’s native resolution. Ideal for portals, claims, and forms that refuse anything but PDF. Runs in your browser.
Your file is processed entirely in your browser. Nothing is uploaded.
Most people converting HEIC to PDF are not doing photography, they are doing paperwork. You photographed a signed contract, a receipt, an ID card, a utility bill, or a damaged parcel with your iPhone, and the system on the other end — an insurer, an HR portal, a bank, a school, an expense tool — accepts PDF and nothing else. The photo is fine; the container is wrong. This tool fixes that in one step, wrapping your photo in a proper single-page PDF that every document system on earth will accept.
Two libraries do the work, both running inside your browser. libheif, compiled to WebAssembly, decodes the HEVC image out of its HEIF container — necessary because PDF has no notion of HEIC and no PDF reader can display one. The decoded image is then re-encoded as a high-quality JPG and embedded by pdf-lib into a PDF page sized exactly to the photo’s pixel dimensions, so nothing is cropped, letterboxed, or scaled down. Given that this conversion is most often used on contracts, medical documents, and identity papers, it matters that no copy is ever uploaded: the entire pipeline runs on your device.
How to convert HEIC to PDF in 4 steps
- 1
Select your HEIC photo
Drop the .heic or .heif file into the dropzone above, or click to browse. Photos taken directly with an iPhone or iPad camera work without any preparation.
- 2
Let libheif decode it
The HEVC image is unpacked in a background worker. This is the step that Windows and Android cannot do without extra codecs, and it happens here entirely in your browser.
- 3
pdf-lib builds the page
The decoded photo is embedded at a high quality setting into a PDF page matching its exact dimensions. No cropping, no white margins, no forced A4 letterboxing.
- 4
Download your PDF
Save the file and upload it wherever PDF is required. If you need to combine several photos into one document, convert each one and then use our Merge PDF tool.
Why a portal wants PDF and not a photo
It looks arbitrary until you see it from the receiving side. A PDF is a self-describing document: it carries its own page geometry, its own physical dimensions in points, and a structure that archival systems, e-signature platforms, and print queues all know how to handle without guessing. An image file carries none of that. A JPG or HEIC has pixel dimensions and, if you are lucky, an EXIF DPI tag that nobody trusts — so a document management system has no reliable way to know whether it is looking at an A4 page, a receipt, or a screenshot. PDF also has a stable long-term archival story (PDF/A is an ISO standard used by public administrations worldwide), supports multiple pages in one file, and can be digitally signed. HEIC adds a second problem on top: it is not merely the wrong container, it is a container most document systems cannot even decode, because HEVC licensing keeps it out of the server-side software stack. Converting to PDF solves both issues at once — the right structure and a universally readable image inside it.
When should you convert HEIC to PDF?
Filing an insurance claim
Claim portals almost always want PDF documentation. Photograph the damage or the paperwork with your phone, convert each shot to PDF, and upload without a rejection.
Submitting an expense report
Expedia, Expensify, SAP Concur, and most in-house expense tools accept PDF receipts. A photographed receipt converted to PDF goes straight through the approval workflow.
Sending a signed document
You printed a contract, signed it, and photographed it with your iPhone. Converting to PDF produces the format the other party expects and can archive properly.
Uploading identity or proof-of-address documents
Banks, landlords, and public services routinely require PDF for ID cards, passports, and utility bills. Converting locally means the document is never handled by a third-party server.
Frequently asked questions
- Can I put several photos into one PDF?
- Not in a single pass with this tool — it produces one page per photo. Convert each HEIC to PDF, then use our Merge PDF tool to combine them in whatever order you like. A dedicated multi-photo-to-PDF pipeline is on the roadmap.
- What page size does the PDF use?
- The page is sized to your photo’s exact pixel dimensions, not forced into A4 or Letter. Nothing is cropped and no white borders are added. Most PDF readers and printers will scale that page to fit the paper when you print it.
- Will the text in my photographed document be searchable?
- No. The PDF contains a photograph of your document, not text. Making the words searchable requires OCR, which is a different technology — we do not run OCR today. The document is perfectly readable by a human, just not by a text search.
- How large will the PDF be?
- Roughly the size of a high-quality JPG of the same photo, typically 2 to 5 MB for a 12-megapixel iPhone shot, plus a few hundred bytes of PDF structure. If you need it smaller for an upload limit, run the result through our Compress PDF tool.
- Is my document uploaded anywhere?
- No, and for this conversion that is the point. The decoding, the JPG encoding, and the PDF assembly all happen inside your browser. Contracts, medical records, and identity documents never leave your device, which is not something a server-based converter can honestly promise.
