Why HEIC
iPhones save photos as HEIC to use about half the space, but many upload forms, Windows apps and printers only accept JPG. Government and exam portals almost always list JPG or JPEG, and many Windows PCs can't open HEIC without extra extensions from the Microsoft Store.
How to convert HEIC to JPG
- Get the .heic files onto the device you are using — copied over a cable, e-mailed, or sent as a document on WhatsApp or Telegram.
- Drop them on the box above. JPG is already selected as the output.
- Leave the quality at 80%, or raise it for near-original quality, then download each photo or all of them as a ZIP.
What changes in the conversion
The picture looks the same, but hidden metadata such as the location and the camera details is removed. That is good for privacy when you share the photo, but keep the original if your gallery app needs the date taken. A Live Photo converts to its still image. Photos sent on WhatsApp as ordinary photos are already JPG, so only files sent as documents, or copied straight from the iPhone, usually need this tool.
Batch conversion
Drop a whole set — each photo is converted and you can save them one by one or as a ZIP.
Stop it at the source
On the iPhone, Settings → Camera → Formats → Most Compatible makes new photos JPG from the start. When you copy photos to a computer over a cable, Settings → Photos → Transfer to Mac or PC → Automatic converts them on the way.
Next steps
If the converted photo is for a form, bring it under the size limit with Compress image to 50 KB or crop it with Passport size photo. To send several as one document, use JPG to PDF.
