How to Convert HEIC to JPG (Free, No Upload)

· Alex Chen, Image Optimization Engineer

TL;DR

HEIC is the format your iPhone saves photos in by default, and it takes up about half the space of an equivalent JPEG. The trade-off is compatibility: outside Safari, most browsers and many apps can't open it, so you convert to JPG when you need a photo to work everywhere. echloe converts HEIC to JPG in your browser, so the photos never leave your device.

What is HEIC, and why does my iPhone use it?

HEIC is Apple's name for HEIF images encoded with HEVC. Apple switched iPhones to it in 2017 with iOS 11, and every iPhone 7 and later captures HEIC unless you change the setting. The reason is storage: a HEIC photo is roughly half the size of a JPEG at the same visual quality, and it can hold 10- and 12-bit color for better HDR.

Why won't my HEIC files open?

Because support is thin once you leave Apple's world. Among browsers, only Safari opens HEIC natively. Photoshop can read it but won't save back to it. Discord doesn't accept it at all, and Facebook quietly converts your upload to JPEG or WebP. The gap is real enough that AP exam takers once failed submissions because their phones uploaded HEIC by default, which pushed the College Board to tell students to send JPEGs instead.

That is the whole case for converting: JPG opens everywhere, HEIC doesn't.

How do I convert HEIC to JPG without losing quality?

A HEIC-to-JPG conversion decodes the original image and re-encodes it as JPEG. JPEG is lossy, so pick a quality level in the 80-90 range. That is high enough that the difference is invisible and low enough that the file stays small. For a batch of photos, convert them all at once rather than one at a time.

Steps that work in any browser:

  • Open the converter and drop in your .heic files (a whole folder is fine).
  • Set output to JPG and quality around 85.
  • Convert and download.

Does converting upload my photos somewhere?

It depends on the tool. Many online converters send your images to a server, which matters if the photos are personal. echloe runs the conversion locally with WebAssembly, so the files stay in your browser and never upload. It's free for up to 15 images a day, with no account needed, so converting a set of iPhone photos to JPG is a drop-and-download job.

Key takeaways

  1. HEIC is iPhone's default since iOS 11; it's about half the size of JPEG at equal quality.
  2. Only Safari opens HEIC natively in the browser, so convert to JPG for everything else.
  3. Use JPEG quality 80-90 to keep photos sharp while shrinking the file.
  4. A local, in-browser converter keeps personal photos off third-party servers.
