Will converting to JPG reduce the quality of my photo?

Slightly, because both HEIC and JPG are lossy and the image is re-encoded. At the default quality of 82 the difference is invisible at normal viewing sizes. If you are archiving or printing, raise the slider to 95 or above, or convert to PNG instead for a lossless result.

Why won't Windows open my iPhone photos?

Because Windows does not ship a HEIC decoder by default. Microsoft offers a codec extension through the Microsoft Store, and some versions charge for it. Converting the file to JPG sidesteps the problem entirely, and the result opens on any version of Windows without extra software.

Is it safe to convert HEIC photos online?

It depends entirely on whether the site uploads them. Most converters do: your photo is transmitted to a server, processed there, and stored for some retention period. This page does not upload anything — the decoding happens in your browser, and the Uploaded readout under each result measures the page's own outbound traffic so you can confirm that rather than trust it.

What happens to the date, location and camera settings?

Most of that EXIF metadata is not carried across. If the capture date or GPS coordinates matter to you, keep the original HEIC alongside the JPG — this tool never alters or removes your original file.

Can I convert a Live Photo?

You will get the still frame. A Live Photo is a HEIC image plus a separate short video file, and JPG has no way to hold the motion part.

How many photos can I convert at once?

As many as your device's memory allows. No limit is imposed here because there is no server doing the work and no bandwidth being paid for. Several hundred photos at once may exhaust memory on a phone; on a laptop it is generally fine.

Is there a file size limit?

No. Upload limits exist because transferring and storing large files costs money, and neither happens here. The practical ceiling is how much memory your browser can allocate for the image.

Will there be a watermark?

No. Nothing is added to the image, and there is no paid tier that removes anything.

Do I need to create an account?

No. There is no account system at all, because there is no server holding files that would need one.

Can I stop my iPhone producing HEIC files in the first place?

Yes. In Settings → Camera → Formats, choose Most Compatible instead of High Efficiency. New photos will be saved as JPG. Existing HEIC files are unaffected, so you will still need to convert those.

Does this work without an internet connection?

Often, but it is not guaranteed. The page and the HEIC decoder are downloaded the first time you use the tool, and your browser normally caches them, so later conversions can work offline. There is no offline app bundled here, so treat it as a convenience rather than a promise.

Why is the JPG sometimes larger than the HEIC?

Because HEIC is a more efficient format. At matched visual quality it is roughly half the size of JPG, which is exactly why Apple adopted it. A JPG that is larger than its HEIC source is not a failed conversion — it is the size cost of using an older, more compatible format.

How do I convert HEIC to JPG?

To convert a HEIC photo to JPG, drop the file onto this page and download the JPG it returns. The conversion runs inside your own browser using WebAssembly, so the photo is never uploaded to a server, there is no file size limit, and no account is required. Your original HEIC file is left untouched on disk.

How to do it

Open the converter. Open this page in any modern browser on Windows, macOS, Android, iPhone or iPad. Nothing needs installing.
Add your HEIC photos. Drag them onto the panel, or click to choose them. You can add as many as you like at once — there is no upload, so there is no queue and no size cap.
Adjust quality if you need to. The quality slider defaults to 82, which is visually indistinguishable from the original at normal viewing sizes. Lower it to fit an upload limit, raise it for printing.
Download the JPG. Each converted photo gets its own download link. The Uploaded readout beside the result shows how many bytes left your browser: on a successful conversion it reads 0 B.

Why are my iPhone photos HEIC?

Since iOS 11, iPhones have saved photos as HEIC by default. It is a genuinely better format: roughly half the file size of a JPG at the same visual quality, with support for 16-bit colour and transparency. Apple switched because it saves an enormous amount of storage across a billion devices.

The problem is everywhere else. Windows needs a codec extension to show HEIC thumbnails, plenty of Android phones cannot open the files at all, and a long tail of web forms, printing services, CMS uploaders and older desktop software simply reject them. That is usually the moment people go looking for a converter.

What does this converter actually do?

HEIC stores its image data using HEVC compression. The converter decodes that data back to raw pixels, then re-encodes those pixels as a JPG.

Both steps run inside your browser as WebAssembly. The file is read from disk into memory, transformed, and handed back to you as a download. It never touches a network connection — which you can watch on the Uploaded readout under each result. That number is measured live from the page’s own outbound requests, not simply printed as a reassurance.

Which quality setting should I use?

Uploading to a web form or emailing — the default of 82 is right. Small, and indistinguishable from the original on screen.
Printing or archiving — use 95 or above, or convert to PNG for a lossless copy.
Squeezing under an upload limit — drop toward 60 and watch the Smaller by readout until the size fits.

Every change re-runs the conversion from your original file, so you can move the slider as many times as you like without compounding quality loss.

Is JPG the right target, or should I pick something else?

JPG is the right answer when compatibility is the goal — it is the one image format that every piece of software written in the last thirty years can open.

If the destination is a website you control, WebP is a better choice: our measurements show WebP landing around 40% smaller than JPG at comparable quality, and it is supported by every current browser. If you need a lossless copy for editing or archiving, PNG will do it, at a substantially larger file size.
