HEIC to JPG Converter

Why HEIC files don't open on Windows or Android

Apple introduced HEIC (High Efficiency Image Container) with iOS 11 in 2017. The format uses the HEVC codec to store photos at roughly half the file size of JPG with equal or better visual quality — which is why your iPhone switched to it automatically.

The catch is compatibility. HEVC decoding requires a licensed codec that Microsoft doesn't include in Windows by default (it's available as a paid add-on from the Microsoft Store). Android support depends entirely on the device manufacturer — some phones handle it, most don't. Web browsers, most email clients, and the vast majority of image editors still expect JPG or PNG.

Converting to JPG solves it permanently. JPG has been universally supported by every device, browser, operating system, and app for the past 30 years.

How to convert HEIC to JPG

1. 1

   Drop your HEIC files

   Drag HEIC photos onto the converter, or click to browse your device. Up to 10 files at once are supported.

2. 2

   Adjust quality if needed

   The default 92% quality is indistinguishable from the original for most uses. Lower it to 80% for smaller file sizes suitable for email or web.

3. 3

   Wait for conversion

   Conversion runs locally in your browser using JavaScript — no upload or server round-trip required.

4. 4

   Download your JPG files

   Save files individually or click Download All to get a ZIP archive of all converted images.

Your photos never leave your device

Most online converters work by uploading your photos to a remote server, processing them, then sending them back. That means your private photos — often personal moments, family pictures, or sensitive documents — pass through infrastructure you know nothing about.

This converter works differently. It uses a JavaScript library called heic2any that runs the entire conversion inside your browser tab. No file is ever transmitted — not even a thumbnail. We have no server that could receive your images, because the conversion never leaves your device. Close the tab and everything is gone from memory.

JPG quality settings explained

JPG compression works on a scale from 1% to 100%. Higher means better quality and larger files; lower means more compression and smaller files. The relationship isn't linear — the difference between 90% and 100% is barely visible, but the file size difference can be 3–4x.

92% (default): Indistinguishable from the original for almost all use cases. This is what most professional tools and cameras use as their standard.

80–85%: Noticeably smaller files. Some compression artifacts become visible on close inspection, but perfectly fine for email attachments, web uploads, or sharing on social media.

95–100%: Near-lossless quality at significantly larger file sizes. Only useful if you're doing further editing or need archival quality. For pure lossless output, use HEIC to PNG instead.

HEIC vs JPG — when to convert

Keep HEIC on your iPhone — it genuinely saves storage without visible quality loss. Convert to JPG when you need to:

• →Share a photo with someone on Windows or Android
• →Upload to a website, form, or CMS that rejects HEIC
• →Attach to an email (many clients won't preview HEIC)
• →Open in photo editing software like Photoshop or GIMP
• →Post on social media platforms that don't support HEIC
