How to Convert HEIC to PNG
Upload Your HEIC Files
Drag and drop your iPhone or iPad HEIC photos into the converter, or click to browse your files. You can select multiple photos at once for batch conversion.
Automatic Lossless Conversion
Your HEIC files are decoded and re-encoded to PNG right inside your browser using WebAssembly. No quality slider needed — PNG is always lossless.
Download Your PNG Files
Download each converted PNG individually or grab them all at once as a ZIP archive. Your original HEIC files remain untouched.
What Is the HEIC Format?
HEIC (High Efficiency Image Container) is the default photo format on Apple devices since iOS 11 and macOS High Sierra. It uses the HEVC (H.265) codec to compress images, delivering roughly 50% smaller file sizes compared to JPEG while preserving the same perceptual quality. Apple adopted HEIC to save storage space on iPhones and iPads without sacrificing the visual detail that users expect from their camera roll.
Despite its efficiency, HEIC poses a compatibility challenge. Windows 10 requires a paid codec from the Microsoft Store, most Linux image viewers cannot open it natively, and many web platforms refuse HEIC uploads altogether. This makes converting to a universal format like PNG essential for sharing or editing on non-Apple systems.
PNG (Portable Network Graphics) is a lossless raster format that preserves every pixel of your image with zero compression artifacts. Unlike JPG, PNG also supports full alpha-channel transparency — making it the preferred choice for graphic designers, web developers, and anyone who needs pixel-perfect accuracy or transparent backgrounds.
HEIC vs PNG — Format Comparison
| Feature | HEIC (Input) | PNG (Output) |
|---|---|---|
| Compression | Lossy (HEVC codec) | Lossless (Deflate) |
| Transparency | Limited support | Full alpha channel |
| Browser support | Safari only | All browsers |
| Windows support | Requires paid codec | Native support |
| File size (typical photo) | 1.5–3 MB | 5–15 MB |
| Editing flexibility | Limited tool support | All editors (Photoshop, GIMP, Canva…) |
| Color depth | Up to 10-bit | Up to 16-bit per channel |
Why Convert HEIC to PNG?
While JPG is the most common conversion target, there are several scenarios where PNG is the better choice:
- •Graphic design work — PNG preserves sharp edges on text, logos, and illustrations without the blurring artifacts that JPG introduces around high-contrast boundaries.
- •Transparent backgrounds — If you want to remove the background from an iPhone photo later, PNG keeps the alpha channel intact, whereas JPG flattens it to a solid white.
- •Lossless archiving — PNG stores every pixel without quality loss, making it ideal for archival purposes when you cannot afford any degradation over repeated edits.
- •Screenshots and UI mockups — iPhone screenshots saved as HEIC convert beautifully to PNG because both formats excel at rendering flat colors and crisp lines.
- •Print preparation — Professional print workflows often require lossless source files. PNG provides a universally accepted lossless format that any prepress application can import.
- •Web development — When building websites or apps, developers frequently need PNG assets with transparency for icons, overlays, and UI elements sourced from iPhone photos.
Real-World File Size Examples
Below are typical file sizes when converting iPhone photos from HEIC to PNG. Since PNG is lossless, files are larger than the compressed HEIC originals.
| Source | HEIC Size | PNG Size |
|---|---|---|
| iPhone 15 photo (12 MP) | 2.1 MB | 9.4 MB |
| iPhone 15 Pro photo (48 MP) | 5.8 MB | 28.5 MB |
| iPad screenshot (2732×2048) | 0.8 MB | 2.3 MB |
| iPhone selfie (12 MP, Portrait) | 1.9 MB | 8.7 MB |
Sizes are approximate and vary depending on scene complexity. Photos with fine detail (landscapes, textures) produce larger PNGs than images with flat, uniform areas.
Your Privacy Is Built In
Every HEIC-to-PNG conversion happens entirely inside your browser using WebAssembly. Your photos are decoded and re-encoded in local memory — they are never uploaded to a server, never stored in a cloud, and never seen by anyone but you. There is no network request involved in the conversion itself.
This architecture means you can use AwesomeToolkit on sensitive photos — medical images, legal documents, personal memories — with complete confidence. Even if your internet connection drops mid-conversion, the process continues because it runs on your own device. When you close the tab, all data is discarded from memory.
Free HEIC to PNG Converter — Lossless iPhone Photos Online — Frequently asked questions
Why convert HEIC to PNG instead of JPG?
PNG is a lossless format — it preserves every detail of your photo with no compression artifacts. It also supports transparency. Choose PNG when image quality is critical or when you need a transparent background.
Are my photos sent over the internet?
No! HEIC → PNG conversion happens entirely in your browser using WebAssembly. Your photos never leave your device and do not pass through our servers.
Can I convert multiple HEIC files at once?
Yes, our tool accepts multiple HEIC files at once. Select or drag and drop as many photos as you want — all are converted in one click.
Will the PNG be larger than the original HEIC?
Yes, PNG files are typically larger than HEIC because PNG is lossless and HEIC uses advanced compression. If file size matters more than quality, use our HEIC to JPG converter instead.
How to open HEIC files on Windows?
The easiest way is to convert your HEIC file to PNG using AwesomeToolkit. Conversion happens entirely in your browser with no installation required. Your photo instantly becomes compatible with Windows, Android, and all standard applications.
Does HEIC to PNG preserve the original resolution?
Yes, absolutely. The conversion preserves the exact pixel dimensions of your original HEIC file. A 4032×3024 iPhone photo will produce a 4032×3024 PNG with every pixel intact.
Can I use PNG files on social media?
Most social platforms accept PNG uploads, though they often re-compress images internally. PNG is ideal when you need to edit or composite the image before posting. For direct sharing where file size matters, JPG may be more practical.
Is there a file size limit for conversion?
Free users can convert HEIC files up to 50 MB each. Pro users enjoy a higher limit. Since conversion runs in your browser, very large files depend on your device's available memory.
Does converting HEIC to PNG preserve EXIF metadata?
The visual content is fully preserved. Some EXIF metadata (GPS location, camera settings) may not transfer to the PNG output, which can actually be a privacy benefit when sharing photos online.
What is the difference between HEIC and HEIF?
HEIF (High Efficiency Image File Format) is the standard, and HEIC is Apple's specific implementation using HEVC compression. In practice, .heic and .heif files are interchangeable, and our converter handles both extensions seamlessly.
