Windows refusing to open your iPhone photos? Convert them to JPG here in the browser — no Microsoft Store codec, no install, no account.

Why Windows struggles with these files

Windows 10 and 11 can show HEIC thumbnails, but actually decoding one needs the HEVC Video Extensions, and on most machines Microsoft charges for that in the Store. Some laptops come with it pre-installed from the manufacturer, which is why a colleague's PC opens the same photo that yours will not. Meanwhile Photoshop, older Office versions and a lot of upload forms simply refuse the format.

Your browser has no such problem: Chrome, Edge and Firefox can decode HEIC in a page. That is the whole trick here — no codec purchase, no admin rights, nothing installed.

The three ways, honestly compared
  1. This page. Drag the photos in, they convert, you save them. Free, no install, works on a locked-down work laptop, and nothing is uploaded.
  2. Buy the HEVC extension from the Store. Worth it if you want Explorer and the Photos app to open HEIC natively forever. It costs money and needs the Store, which plenty of managed machines block.
  3. Email them to yourself from the iPhone. Mail converts to JPG on the way out if you send at a smaller size — but it quietly shrinks the photo, and it is slow for more than a handful.

For a folder of holiday photos the first one is the fastest: select the whole lot, and once more than one has converted a Save all button appears.

Nothing leaves your device. The conversion runs inside this page using your browser's own image engine, so your photos are never uploaded to us or to anyone else — there is no server here to upload them to. That also means it keeps working on a bad connection, and it costs nothing per file.

If Windows still will not cooperate

Once they open, old scans and faded prints can be repaired and enlarged with PicReviver, and ScanReviver turns a stack of photos into one PDF.

Converting straight from the iPhone instead of a Windows PC? HEIC to JPG on iPhone covers that. Got a whole folder to get through? Bulk HEIC to JPG handles the lot in one pass.

Common questions

Do I need the HEVC codec from the Microsoft Store?

No. Your browser decodes the photo itself, so nothing has to be bought or installed.

Will this work on a locked-down work laptop?

Yes, as long as you can open a web page. There is nothing to install and no admin rights are involved.

Are the photos uploaded to a server?

Nothing at all. Your photos are converted inside your browser and never sent anywhere, so there is no file on our side to delete, share or train on.

How many can I do at once?

As many as you can select. They convert one after another and a Save all button appears once more than one is ready.

Does it work in Edge as well as Chrome?

Yes — Edge, Chrome and Firefox all decode HEIC in the page. Very old versions of any of them may not, so update if a file refuses.

Does converting reduce the quality?

Converting is not lossless — HEIC and JPG both throw away detail, so you are re-encoding once. The JPGs come out at quality 0.92, which is high enough that you would struggle to see the difference on a photo, and the file usually lands somewhere between the same size and twice the size of the HEIC.

Can I go the other way, JPG back to HEIC?

No, and it would not help you: HEIC is the format Windows struggles with. If you want smaller files, convert to WebP on the WebP page instead.
