Turn HEIC photos into perfect PDFs

Windows does not include native HEIC support out of the box. The format relies on the HEVC (H.265) codec, which Microsoft only ships through an optional Microsoft Store extension — one most users never install. Even on Windows 11, HEIF codec support can vanish after a clean OS reinstall. The easiest fix is to use a HEIC to PDF converter before sharing photos with Windows users, rather than asking recipients to hunt down codec packages themselves.

It depends entirely on whether the tool uploads your files to a server. Many free online converters do transmit your photos to external servers where they are processed, stored temporarily, and potentially logged — a serious risk if your images contain personal, medical, or financial information. This HEIC to PDF converter processes everything locally inside your browser using JavaScript. Your files never leave your device. You can confirm this yourself: open your browser’s developer tools, watch the Network tab, and you will see zero upload traffic during conversion.

Minimally, and only if you choose it. The converter decodes your HEIC to a full-resolution bitmap, then re-encodes it as JPEG inside the PDF at your chosen quality level. At High (92%), the result is visually indistinguishable from the original — perfect for printing or archiving. At Medium (70%), the PDF is roughly 40% smaller, with only very slight compression artifacts visible at extreme zoom. For any archival or print use, always select High quality.

Yes — batch HEIC to PDF conversion is fully supported. Drop an entire folder of photos onto the upload area in one go. You can then choose to convert each file into its own individual PDF, or merge all photos into a single multi-page PDF document. Both modes process every file in one pass with a shared progress bar, so you can walk away and return when it is finished.

No account, no email, no registration of any kind. There is no sign-up form, no confirmation step, and no “enter your email to download” gate. Open the page, convert your HEIC files, download the PDF — that is the complete workflow. Because everything runs in your browser, there is nothing to create an account for.

HEIC is Apple’s modern photo format (iOS 11+, 2017), while JPEG has been the internet’s photo standard since the early 1990s. Key differences: File size — HEIC files are ~50% smaller than an equivalent JPEG at the same visual quality, so your iPhone stores nearly twice as many photos per gigabyte. Features — HEIC can store Live Photos, burst sequences, depth maps, and 10-bit wide-colour data in a single container; JPEG supports none of these. Compatibility — JPEG opens natively on every platform ever made; HEIC requires special codec support outside Apple’s ecosystem. For sharing, PDF or JPEG is always the safer choice.

Yes. The converter is fully responsive and runs in Safari on iOS and iPadOS 15 or later. Open it on your iPhone, select HEIC photos from your Camera Roll using the file picker, convert them, and save the PDF to Files or share via AirDrop, email, or Messages — all without leaving the browser. Note that on iOS, drag-and-drop is not supported in Safari, but the tap-to-browse button works perfectly.

Your files exist only in your browser’s memory while the page is open. They are never written to disk by the tool and never sent to any server. The moment you close or refresh the tab, the browser releases that memory — there is no cache, no session storage, and no server log to clear. If you need to convert the same files again, simply reload the page and start fresh.
