HEIC to PDF Converter — Free, Private, In-Browser

Open the converter

This HEIC to PDF converter turns an iPhone HEIC photo into a clean, single-page PDF entirely inside your browser. Nothing is uploaded to a server, there is no signup, and the file is ready to download in seconds.

iPhones save photos as HEIC because the format is roughly half the size of an equivalent JPG. That works fine inside Apple, but the moment you need to attach the photo to a contract, email it to a client, or upload it to a portal, you usually want a PDF — every operating system, browser, and printer opens PDFs without arguing about codecs.

The conversion runs locally: the HEIC is decoded by a WebAssembly module, re-encoded as a JPEG at the quality you choose, and embedded into a single-page PDF using pdf-lib. The PDF page is sized to match the photo's pixel dimensions, so no detail is lost and nothing is stretched. Your file never leaves your device.

Use the quality slider to balance fidelity against file size, and use the max-dimension control to downscale a 4032×3024 iPhone photo to something that fits an email attachment limit or a portal's upload cap.

How it works

  1. Drop a .heic or .heif file onto the converter. HEIC to PDF is auto-selected.
  2. Optionally tweak quality (default 90%) and max-dimension to control output size.
  3. Download the resulting single-page PDF — same pixel dimensions as the photo, embedded as JPEG inside the PDF.

Why use this tool

Most "HEIC to PDF" sites upload your photo to their server, run a conversion, and serve a link back. That works, but it puts your photo on someone else's disk. This tool runs the whole pipeline in your browser, so the bytes never leave your device. It also installs as a PWA — once you've visited it, you can convert offline.

Frequently asked questions

Is this HEIC to PDF converter free?

Yes. The tool is free, has no signup, no watermark, and no daily limit. The whole conversion runs locally inside your browser.

Is HEIC supported on Windows or Android?

Natively, support is limited. Windows can install the HEIF Image Extensions for previewing, but most apps still struggle. Android support depends on the OEM. Converting to PDF gives you something every device, browser, and printer can open.

Can the iPhone export a HEIC to PDF natively?

You can hand-roll it by opening the photo in Files, choosing Print, and pinch-zooming the preview to share as PDF — but it is fiddly, embeds the photo at print-page dimensions, and is awkward in batches. This tool keeps the original pixel dimensions and outputs a single-page PDF in one click.

Is my photo uploaded to a server?

No. The HEIC is decoded with a WebAssembly module in your browser, re-encoded as JPEG, and embedded into a PDF using pdf-lib — entirely on your device. Nothing is uploaded.

Can I make a multi-page PDF from many HEICs?

Yes — drop multiple iPhone photos onto the Image to PDF tool. HEIC files are auto-decoded and stacked into a single multi-page PDF. The dedicated HEIC to PDF tool here keeps it focused on a single photo for the cleanest one-page output.
