HEIC to JPG Converter - Convert iPhone Photos Online

Convert HEIC and HEIF photos from your iPhone to universally supported JPG files, up to 20 at a time. Free and fully browser-based: your photos never leave your device.

Files are converted locally in your browser and are never uploaded to any server.

90% is a good balance of quality and file size. Use 100% for archiving, 70-80% for web use.

Why iPhones Shoot HEIC and How to Convert It to JPG

Since iOS 11 (2017), iPhones save photos in HEIC (High Efficiency Image Container), Apple's implementation of the HEIF standard. HEIC files are roughly half the size of an equivalent JPG at the same visual quality, which is why Apple adopted it. The catch: many Windows PCs, older Android devices, web forms, and content management systems still cannot open HEIC files. Converting to JPG solves that instantly, because JPG has been the universal photo format since the 1990s.

This converter handles up to 20 photos per batch and runs entirely in your browser. If your browser can decode HEIC natively (Safari on recent macOS and iOS can), the tool uses that fast path. Otherwise it falls back to a WebAssembly decoder that is downloaded on demand. Either way, nothing is uploaded: family photos, ID documents, and work screenshots all stay on your device, which is a real privacy advantage over server-side converters.

The quality slider controls JPG compression. At 90% quality, a typical 12-megapixel iPhone photo of around 2 MB in HEIC becomes a JPG of 3-5 MB, since JPG compresses less efficiently. Dropping to 75% often halves that JPG size with barely visible differences on screens, which is the sweet spot for email attachments and web uploads. Note that JPG does not support transparency or the 10-bit color some HEIC files carry, and Live Photo motion data is not preserved, only the still frame.

A tip for iPhone users who want to avoid the problem altogether: in Settings, Camera, Formats you can switch from High Efficiency to Most Compatible, which makes the camera shoot JPG directly, at the cost of roughly double the storage per photo. And if you email a photo from the Photos app, iOS usually converts it to JPG automatically. For the HEIC files you already have, this tool is the fastest route. After converting, you can shrink results further with the Image Compressor or change dimensions with the Image Resizer, both free on ToolForte.

How the HEIC to JPG Converter Works

  1. 01Select up to 20 HEIC or HEIF photos from your iPhone, iPad, or computer.
  2. 02Set the JPG quality with the slider: 90% is a good default for most uses.
  3. 03Click Convert. Each file shows its own progress and resulting JPG size.
  4. 04Download each converted JPG. Nothing is uploaded: conversion happens in your browser.

Converting iPhone HEIC Photos to JPG

iPhones have saved photos as HEIC since iOS 11 because it stores the same image in about half the space of JPG. The downside is compatibility: many Windows programs, web forms, and older devices cannot open HEIC. This tool converts each photo locally in your browser, using your browser's native decoder when available and a WebAssembly fallback otherwise, so your photos never leave your device. JPG output works everywhere but does not keep transparency or Live Photo motion data.

When to Use This Tool

Use it whenever a website, client, or application refuses your iPhone photos: job application portals, insurance claim forms, marketplace listings, older photo printing kiosks, or Windows colleagues who see broken thumbnails. It is also handy before emailing photos to someone whose device you do not know. Because everything runs locally, it is safe for private photos, ID documents, and anything else you would not upload to a random conversion site.

Common Use Cases

  • Convert iPhone photos so a job or government web form accepts them
  • Shrink and convert photos before emailing, then compress further → Compress Images Online
  • Make photos viewable for Windows users without extra codecs

Tips

  • Files are converted one at a time; keep the tab open until every file shows a download button.
  • If a file fails, check that it is really a HEIC/HEIF photo and not a renamed video or PDF.
  • To stop your iPhone producing HEIC at all, switch Settings, Camera, Formats to Most Compatible.

Frequently Asked Questions

Are my photos uploaded to a server?→
No. The conversion runs entirely inside your browser using JavaScript and WebAssembly. Your photos never leave your device, which you can verify by loading the page and then switching off your internet connection: conversion still works.
What is a HEIC file exactly?→
HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard, using HEVC compression. It stores photos at roughly half the file size of an equivalent JPG, which is why Apple made it the default camera format in iOS 11 back in 2017.
Why is my JPG larger than the original HEIC?→
HEIC compresses more efficiently than JPG, so a 2 MB HEIC often becomes a 3-5 MB JPG at 90% quality. Lower the quality slider to 70-80% to get smaller files with barely visible quality loss on screens.
What quality setting should I choose?→
90% is a good all-round default. Use 100% only for archiving, since it produces much larger files. For email attachments and web uploads, 70-80% typically halves the file size compared to 90% with differences most people cannot see.
Can I convert 50 photos at once?→
The tool accepts up to 20 files per batch to keep memory use stable, since each photo is decoded in your browser. For more photos, convert in batches of 20, or set your iPhone camera to Most Compatible mode (Settings, Camera, Formats) to shoot JPG directly in the future.
