Convert HEIC to JPG securely in your browser

Standardize your Apple photos to the universally compatible JPG format without compromising security.

Deep-Dive Guide & Information

Format Definition

HEIC (High Efficiency Image Container) is Apple's modern image format, introduced with iOS 11 to replace JPEG. Built on the High Efficiency Video Coding (HEVC) standard, it allows iPhones and iPads to capture high-quality photos at roughly half the file size of an equivalent JPG. HEIC supports features like 16-bit color depth, transparency (alpha channel), and embedded image sequences (such as Live Photos).

Why Convert?

Despite its technological superiority, HEIC suffers from a major drawback: compatibility. Most Windows PCs, Android devices, older Smart TVs, and web platforms (including email clients and social media networks) cannot render HEIC natively. Converting HEIC to JPG ensures your images can be viewed, shared, and edited on any device, anywhere in the world, without requiring specialized software.

How It Works Locally

On Apple devices where the browser can already decode HEIC natively, we use that built-in decoder directly. Everywhere else, we lazily load heic2any, a JavaScript/WebAssembly library, the first time you add a HEIC file. Either way, the decoded image is drawn onto a canvas at its original orientation, then re-encoded as a JPEG blob, ready for instant download.

Impact on Image Quality

While JPEG is a lossy format (meaning some visual data is discarded to minimize file size), our converter lets you control the quality setting. By default, we use an 80% compression quality which strikes an ideal balance, reducing file size significantly while keeping visual quality virtually indistinguishable from the original. No pixels are scaled down unless you manually apply a resize constraint.

Guaranteed Privacy & Data Safety

We believe your photos are your business. This tool is built entirely on a client-side execution model. This means that when you select or drag-and-drop a file, the processing is performed in your browser's local sandbox. No data, metadata, or image bytes ever touch our servers or any external API.

Browser Support & Performance

HEIC decoding is a resource-intensive operation because standard web browsers do not natively support the HEVC codec. It is fully supported in Google Chrome, Microsoft Edge, Mozilla Firefox, and Safari on modern hardware. Because decoding occurs in memory, converting extremely large images (over 50MP) or massive batches simultaneously might experience throttling on devices with limited RAM, such as older mobile phones.

Frequently Asked Questions

What is HEIC, and why did Apple switch to it?
HEIC stands for High Efficiency Image Container. Apple switched to it in 2017 to save storage space on iPhones. It compresses images much more efficiently than JPG, saving about 50% of the storage space while preserving equal or better visual quality.
Will I lose my metadata (location, date, camera info) during conversion?
Visual orientation is preserved, so photos never come out sideways. However, converting through a canvas — the same technique every browser-based tool uses — does not carry over EXIF metadata like GPS location, capture date, or camera settings. If you need that metadata kept, convert a copy and keep the original HEIC file as your archive.
Why does converting HEIC feel slower than other formats?
Because HEIC uses the highly complex HEVC codec, browsers must decode it programmatically using Javascript/WASM rather than the browser's native hardware-accelerated image decoders. This requires intensive CPU work, especially for high-resolution iPhone photos.
