iPhone photos are usually HEIC files. Many websites, older Windows PCs, and some printers still expect JPEG. You do not need to send the pictures to a server to make that change.
This page is the practical version of that job: drop the photos in, pick a size, and download JPEGs. The decoder runs on your device.
What you are converting
A HEIC file is a photo stored in the HEIF container, almost always with HEVC compression. Apple uses it because the same picture takes less space than a JPEG. The file name ends in .heic or, less often, .heif.
A JPEG is the older format that almost every app, form, and printer already accepts. Converting does not invent detail. It redraws the picture into a format other software can open.
Convert a photo
- Open HEIC to JPEG on the phone or computer that has the files.
- Drop the HEIC files onto the page, or choose them from the photo library.
- Leave the preset on Original if you want the full photo, or choose Web or Small if you need a smaller file.
- Download one JPEG, or a ZIP if you added several.
You can add up to 30 photos. Files that are not HEIC or HEIF are skipped. Anything over 50 MB is skipped so the browser does not run out of memory.
Which preset to use
Original keeps the full pixel size and encodes the JPEG at 92% quality. That is the right choice when you want a print, an archive copy, or the closest match to the phone photo.
Web limits the longest side to 2048 pixels and uses 80% quality. That is enough for a website, a slide, or a large email attachment.
Small limits the longest side to 1280 pixels at 70% quality. Use it for chat apps and forms that reject large uploads.
You can also set the longest side and the quality yourself. Moving either control switches the preset to Custom. Press Convert again so the photos already in the list are rebuilt with the new settings.
JPEG at a high quality is often larger than the HEIC you started with. HEIC is simply a more efficient way to store the same picture. If the JPEG is too big, lower the quality or the longest side. Do not expect a high-quality JPEG to be smaller than the original HEIC.
What stays in the file
The picture is rotated so it stays upright. For JPEG, date and camera details are copied unless you turn that off. Location is left out unless you turn Include location on. PNG and WebP do not carry those details.
Live Photos contribute the still frame only. The short motion clip is not included.
Why doing it locally matters
A photo of a face, a document, or a house is not something to upload just to change the file type. The conversion on this site uses a HEIC decoder in the browser. The bytes of the photo are not sent to heictojpegconvert.app.
That also means a very large batch is limited by the memory of your device. Convert the set, download the ZIP, then clear the list before starting another.
Frequently asked questions
Will the JPEG look the same as the HEIC?
At Original, the JPEG is very close. It is a new encode, so it is not a bit-for-bit copy. If you need the smallest file, use Small and accept a little less detail.
Can I convert HEIC to JPG specifically?
Yes. JPG and JPEG are the same format. The downloaded file uses the .jpg extension.
Does this work on Windows, Mac, and iPhone?
Yes, in a current Chrome, Edge, Firefox, or Safari. On iPhone, choose the photos from the library. On Android, an installed copy of the site can also receive shared HEIC files.
