How to Convert HEIC to PDF on Windows 10 and 11 (2026 Guide)

You copied a folder of photos off an iPhone, double-clicked one on your Windows PC, and nothing useful happened. Maybe the Photos app offered to sell you something. Maybe File Explorer showed a blank icon where the thumbnail should be. Either way, the file ends with .heic and Windows is refusing to deal with it.

This guide covers three ways to turn those files into PDFs on Windows 10 and Windows 11 — including one that skips the codec problem entirely — and explains why Windows behaves this way in the first place.

Why Windows can't open your HEIC files

HEIF is a container format. The pictures inside it can be compressed several different ways, and the method Apple uses is HEVC, also known as H.265. Microsoft's own developer documentation is explicit about this:

"HEIF is a container, similar to TIFF, that can use different compression methods. The default compression method is the High-Efficiency Video Codec (HEVC). HEIF files that are compressed with HEVC typically use the .heic file extension. […] The HEVC and AV1 codecs might not be available on all PCs."

So opening a .heic file on Windows takes two separate pieces:

• HEIF Image Extensions — free in the Microsoft Store. This teaches Windows the container.
• HEVC Video Extensions — around $0.99. This is the actual decoder. HEVC is patent-encumbered, and Microsoft passes the licensing cost on.

Without the second one, the first is not enough: the HEIF extension can open the box but cannot read what is inside. That is the whole reason a fresh Windows install shows you a blank thumbnail instead of your photo.

There is also a free variant called HEVC Video Extensions from Device Manufacturer, which some PC makers license on your behalf. It is not listed in Store search results, and whether it installs depends on your hardware — so it is worth a try, but not something to count on.

Method 1: Convert in your browser (no codec, no install)

Modern browsers do not depend on the Windows codec at all. That is what makes this the shortest path on a PC that cannot open HEIC.

1. Open heictopdf.dev in Chrome, Edge, or Firefox.
2. Drag your .heic files onto the page, or click Select HEIC Files and pick them in the file dialog. Files up to 50MB each are accepted, which is well beyond what any iPhone produces.
3. Conversion starts on its own. Each photo is decoded and written into a PDF page sized to the image.
4. Click Download PDF next to each finished file.

The conversion runs inside the browser tab. Nothing is uploaded, there is no server that receives your photos, and the finished PDFs are discarded from memory after 10 minutes. For work documents, ID scans, or anything you would rather not hand to a website, that difference matters more than the convenience.

It also means the result is identical whether you do it on a locked-down work laptop, a shared family PC, or a machine where you have no rights to install anything.

Method 2: Microsoft Print to PDF (after installing the codec)

If you have already paid for the HEVC extension — or your PC came with the manufacturer version — Windows can do this without any third-party software. Microsoft Print to PDF has shipped with Windows since Windows 10 and is enabled by default.

1. Install HEIF Image Extensions and HEVC Video Extensions from the Microsoft Store, then restart File Explorer (or just sign out and back in).
2. Select your HEIC photos in File Explorer. Right-click and choose Print.
3. In the print dialog, set Printer to Microsoft Print to PDF.
4. Pick a layout on the right. Full page photo gives one image per page; the contact-sheet layouts fit several per page.
5. Click Print, then choose where to save the PDF.

Two things to watch. The print dialog adds its own page margins, so the image will not fill the page edge to edge. And selecting multiple photos here produces one PDF containing all of them — handy if that is what you wanted, annoying if you needed separate files.

Method 3: Turn several photos into one PDF

Expense reports, insurance claims, and rental applications usually want a single document rather than eleven attachments.

1. Add all the photos at once on heictopdf.dev.
2. Wait for at least two to finish. A Combine into one PDF panel appears above the list.
3. Put the pages in order using the arrows next to each file. The list order is the page order.
4. Click Combine and download the single multi-page PDF. Up to 30 pages.

Each page is sized to its own image, so a mix of portrait and landscape shots will not get squashed into one shared page shape. Merging reuses the images already decoded in step 2, so it finishes almost instantly rather than reprocessing everything.

Common Windows problems and how to fix them

Thumbnails are blank in File Explorer

Normal before the codecs are installed. If they are still blank afterwards, the thumbnail cache is stale: run Disk Cleanup, tick Thumbnails, and clear it. Explorer rebuilds the cache on the next folder visit.

The Photos app says it needs an extension

That prompt links to the paid HEVC package. You do not have to buy it to get a PDF — Method 1 works without any of it.

OneDrive turned my photos into JPG

Some import paths — OneDrive camera upload, the Photos import wizard, and iCloud for Windows depending on its settings — silently convert HEIC to JPEG on the way in. If you need the untouched originals, copy them off the phone with File Explorer instead of letting a sync client do the import.

The photo is very large

Convert it anyway. There is no need to shrink a 48MP shot first: the converter resamples the image as it reads it, so a large original costs no more than a small one and still comes out as a compact PDF. The 50MB ceiling exists to catch corrupt input, not real photos — a 48MP HEIC is usually under 12MB.

The upload portal says my PDF is too big

Unlikely with a PDF from here — pages are written at 200dpi A4, which normally lands well under a megabyte per page. If you are hitting a limit, it is probably because you merged many photos into one document; split them into separate PDFs instead.

The PDF looks softer than the original photo

Expected, and deliberate. The image is resampled to 200dpi at A4 and re-encoded as a high-quality JPEG, which is the right trade when the PDF exists to be uploaded or printed rather than archived. Your original HEIC is untouched if you need the full-resolution file.

Frequently asked questions

Can Windows 11 open HEIC without extra software?

Not reliably. The container support is there, but .heic files from an iPhone are HEVC-compressed, and the HEVC decoder is a separate Store package that usually costs about $0.99. A browser sidesteps the whole thing.

Do I have to pay $0.99 to convert HEIC to PDF?

No. The fee buys you the ability for Windows itself to display HEIC. If your goal is a PDF, a browser-based converter does not need the Windows codec at all.

Is it safe to convert photos on a website?

It depends entirely on whether the site uploads them. Many converters do, process the file on a server, and keep it for some retention window. heictopdf.dev does the work in your browser — there is no upload endpoint and no server that could receive the file.

How do I convert a whole folder at once?

Select every file in the folder with Ctrl+A and drop them all onto the converter. They queue up one at a time so the tab stays responsive, and you can then either download them individually or merge them into one PDF.

What is the difference between HEIC and HEIF?

HEIF is the container. HEIC is the common case of that container using HEVC compression, which is what iPhones produce. A HEIF file compressed with AV1 instead uses the .avif extension. Both .heic and .heif work with the converter.

The short version

Windows makes HEIC harder than it needs to be, and the fix Microsoft offers costs a dollar and a Store account. If all you need is a PDF for a form, an application, or an email attachment, open heictopdf.dev, drop the files in, and download the result. No codec, no install, no upload.
