iPhones shoot HEIC by default, and half the internet's upload forms still refuse it. Converting to JPG makes those photos usable everywhere — and since these are usually personal photos with embedded location data, converting them locally instead of uploading them to a converter site is the privacy-sane choice.
One honest caveat this page leads with rather than buries: browsers differ on HEIC. Safari (and most browsers on Apple devices) decode HEIC natively; Chrome and Firefox on Windows or Linux typically do not. The tool checks your browser when you drop a file and tells you plainly if it can't decode it, instead of failing halfway.

This is Convert Image Format preconfigured for this task — open the full tool for every option.
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
HEIC decoding is licensed at the operating-system level. Apple platforms ship a decoder, so Safari can hand the browser decodable pixels. Most Windows and Linux browsers ship without one. The tool tests your actual browser rather than guessing.
Meaningfully, yes. Phone photos routinely embed GPS coordinates and timestamps. Uploading them to a converter service hands all of that to a third party. Here the photo is decoded and re-encoded in your tab, and the JPG output carries no EXIF metadata.
The fastest local options: on iPhone, share the photo — iOS converts to JPG automatically in many share paths; or open this page in Safari on a Mac. We'd rather point you there than silently upload your photo to a server.
Technical guidance for choosing settings and reviewing the result.
There is no quality percentage that makes every image exactly 1 MB or 100 KB. A reliable target-size workflow measures real encodes, preserves the best result under the limit, and tells you when resizing is necessary.
