How does Pixlush process HEIC files in the browser?

Apple's HEIC format relies on the advanced HEVC (H.265) video compression standard, which is why it achieves such incredibly small file sizes compared to JPG. However, web browsers do not natively support decoding HEVC image data directly through the standard HTML canvas.

To solve this, Pixlush loads a highly optimized WebAssembly (WASM) decoder when you use this tool. This decoder runs securely in your browser's memory, reads the binary HEIC data, extracts the raw pixel arrays (including any alpha transparency layers), and then encodes those pixels into a standard, lossless PNG file. This entire complex operation happens in milliseconds using your device's local CPU.

Why Convert HEIC to PNG?

HEIC (High Efficiency Image Container) is the modern default format used by iPhones and iPads to save storage space without sacrificing visual quality. However, the wider digital ecosystem has not fully adopted it yet. Many professional design tools, older Windows versions, Android devices, and social media platforms still reject HEIC uploads. Converting your photos to PNG solves these compatibility issues while offering several unique advantages:

• Universal Compatibility: PNG is one of the most widely supported image formats on the internet. It works flawlessly across every web browser, operating system, and image editor in existence.
• Preserve Transparency (Alpha Channels): Unlike JPG, which fills empty space with solid white pixels, PNG fully supports transparency. If your HEIC file contains transparent layers (such as a subject cut out using iOS 16's background removal feature), our converter will correctly map that transparency into the resulting PNG file.
• Lossless Quality: PNG is a "lossless" format. This means that when we convert the raw pixel data from your HEIC file, we do not apply any further destructive compression. Your converted photo will maintain the absolute highest possible visual fidelity.
• Perfect for Designers: Because it is lossless and supports transparency, PNG is the preferred format for web graphics, logos, UI elements, and digital art. If you are importing an iPhone photo into Figma or Photoshop, PNG is often the ideal intermediary format.

The Safest Way to Convert iPhone Photos

The photos you take on your iPhone are deeply personal. Furthermore, they contain hidden EXIF metadata that reveals exactly when and where the photo was taken (GPS coordinates), as well as the specific device you used.

When you use traditional online converters, you are uploading these personal memories and location data to an unknown third-party cloud server. This is a significant and unnecessary privacy risk. You have no guarantee that your photos are immediately deleted or that the metadata isn't being harvested.

Pixlush eliminates this risk entirely. By leveraging on-device WebAssembly processing, your HEIC files are converted locally on your computer or phone. Your photos never leave your device, they never touch a network connection, and nobody else ever sees them. It's the ultimate combination of web-app convenience and desktop-software security.
