Why Convert HEIC to PNG?
While HEIC offers excellent compression, PNG provides lossless quality with universal support. Convert HEIC to PNG when you need to preserve every detail without any compression artifacts, or when you need transparency support for graphics and overlays.
When to Convert HEIC to PNG
Preserving screenshot quality from iPhone
When your iPhone captures screenshots with text and UI elements, converting to PNG preserves crisp edges and text readability that JPG compression would blur.
Creating graphics with transparency
PNG supports alpha transparency, allowing you to extract subjects from HEIC photos and use them as overlays in design projects.
Archiving photos without quality loss
PNG is lossless — converting HEIC to PNG ensures no additional compression artifacts are introduced, making it ideal for long-term photo storage.
HEIC vs PNG: File Size Comparison
Based on a typical 12-megapixel photograph (4000 × 3000 pixels) at default quality settings.
Lossless output preserves every pixel. File size increases significantly because PNG does not use perceptual compression like HEIC.
HEIC vs PNG Comparison
| Feature | HEIC | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Yes | Yes |
| Animation | Yes | No |
| Browser Support | Safari only | Universal |
| Typical File Size | Smaller (50% less than JPG) | Medium to large |
| Best For | iPhone/iPad photos, storage efficiency | Logos, graphics, screenshots, transparency |
HEIC to PNG on Every Platform
iPhone / iPad
Your iPhone saves photos as HEIC by default since iOS 11. To convert to PNG, simply upload your photos to PhotoFormatLab — no app installation needed. Alternatively, you can change your camera settings to capture in JPG: go to Settings → Camera → Formats → Most Compatible.
Windows PC
Windows 10/11 can display HEIC files if you install the "HEIF Image Extensions" from the Microsoft Store (free). However, most Windows applications still cannot edit HEIC files — converting to PNG gives you full compatibility with Photoshop, Paint, GIMP, and every other Windows application.
Android
Android devices cannot natively open HEIC files sent from iPhones. Converting to PNG before sharing ensures Android users can view your photos in any gallery app without installing additional software.
Batch Conversion
PhotoFormatLab processes all files in your browser using Web Workers for parallel conversion. You can convert hundreds of HEIC files to PNG simultaneously — the speed depends on your device's CPU, not your internet connection.
Common Issues and Solutions
My HEIC file shows as corrupted or will not load
Some HEIC files from older iOS versions use a slightly different encoding. Try updating your iPhone to the latest iOS, or re-export the photo from iCloud.com in its original format before converting.
My animated HEIC file only shows the first frame after conversion
PNG does not support animation. Only the first frame is extracted during conversion. To preserve animation, convert to WebP or GIF instead.
Conversion is very slow on my device
Large files (over 20 MB) require significant CPU processing since conversion happens entirely in your browser. Close other browser tabs to free up memory, or try converting fewer files at a time. On mobile devices, the process is naturally slower than on desktop computers.
The output file is much larger than expected
This typically happens when converting from a highly compressed format (like HEIC) to a less compressed one (like PNG). The output reflects the actual image data, not the compression efficiency of the source. Lossless formats like PNG prioritize quality over file size.
Frequently Asked Questions
For a typical 12-megapixel photograph (4000×3000 pixels), a HEIC file of approximately 2.5 MB converts to a PNG file of approximately 14.2 MB — a change of +468% (PNG is much larger). Lossless output preserves every pixel. File size increases significantly because PNG does not use perceptual compression like HEIC.
PNG uses lossless compression, so there is no quality setting to adjust — every pixel from your HEIC file is preserved exactly in the output. The file size is determined by the image content rather than a quality parameter.
No. PhotoFormatLab converts files entirely in your browser using JavaScript, Canvas API, and WebAssembly. Your images never leave your device — no upload, no server processing, no cloud storage. This makes the conversion completely private and works even without an internet connection after the page loads.
There is no artificial limit. You can convert hundreds of files in a single batch. The practical limit depends on your device's available memory and CPU speed. For very large batches (500+ files), we recommend processing in groups of 50-100 for optimal performance.
Most individual files convert in under 2 seconds on a modern device. A batch of 50 files typically completes in 30-60 seconds. Since processing happens on your device, conversion speed depends on your hardware — desktop computers are generally faster than phones. There is no upload or download wait time.
