Convert HEIC to PNG in Batch
📋 HEIC vs PNG Format Specifications
| Feature | HEIC (High Efficiency Image) | PNG (Portable Network Graphics) |
|---|---|---|
| Format Name | HEIC / HEIF (High Efficiency Image Container) | PNG (Portable Network Graphics) |
| Compatibility | ⚠️ Restricted (primarily Apple devices, needs plugins/extension elsewhere) | ✅ Universal (works on all browsers, operating systems, and platforms) |
| Compression Type | Lossy (High Efficiency HEVC) | Lossless (Deflate compression) |
| File Size | Very Small (approx. 50% smaller than JPEG, much smaller than PNG) | Moderate to Large (due to lossless quality retention) |
| Use Case | Saving storage space on iPhones and iPads | Web design, icons, logos, forms requiring high quality |
⚠️ Note: Converting from HEIC to PNG creates high-quality, lossless images. Due to the lossless nature of PNG, the converted files will be larger than the original HEIC files.

Free HEIC to PNG Converter – Bulk Convert iPhone HEIC to PNG Locally
HEIC (High Efficiency Image Container) is the standard format used by modern iPhones and iPads since iOS 11. While it provides excellent compression — keeping file sizes incredibly small without sacrificing quality — its lack of native compatibility on non-Apple systems represents a significant challenge. Trying to view HEIC photos on older Windows versions, upload them to online web forms (like government job registrations, college applications), or edit them in standard design software frequently fails with format errors.
This free online HEIC to PNG Converter resolves these compatibility hurdles instantly. PNG is widely recognised as the industry standard for lossless images. Unlike JPG, PNG retains exact pixel-by-pixel detail and supports transparent backgrounds, making it perfect for screenshots, logo designs, web pages, and documents where image quality must be preserved.
A primary concern with most online converters is data privacy. Most tools force you to upload files to remote cloud servers, which risks your private images being stored or processed externally. This HEIC to PNG converter operates entirely client-side using WebAssembly. The file loading, H.265 (HEVC) decoding, and PNG encoding all happen inside your browser window. Your photos never leave your device — giving you maximum speed and complete privacy.
What is HEIC and why do iPhones use it?
HEIC is Apple's implementation of the HEIF (High Efficiency Image Format) standard, which uses the HEVC (H.265) video codec to compress still images. Compared to JPEG, HEIC files are roughly 50% smaller at the same visual quality level. For users with limited storage on their devices, this is a meaningful advantage. However, HEIC's reliance on licensed video codec technology means it isn't natively supported by many non-Apple operating systems and browsers without additional software or codec packs.
What is the difference between HEIC and HEIF?
HEIF is the general container format standard developed by the Moving Picture Experts Group (MPEG). HEIC is Apple's specific implementation of HEIF using HEVC compression. In practice, both file types (.heic and .heif) behave identically and this tool converts both. When someone refers to an "iPhone photo format," they are referring to HEIC specifically, but both extensions come from the same underlying technology.
When should you convert HEIC to PNG?
- Uploading to Web Portals: Many online registration and submission portals — including government job applications, university admissions, and exam forms — only accept PNG or JPG uploads.
- Editing on Windows or Android: When you need to edit or share iPhone pictures on non-Apple devices without installing additional media codecs or extensions.
- Preserving Original Quality: PNG is a lossless format, so converting to PNG ensures all original detail is preserved. Converting to JPG instead would introduce additional compression artefacts.
- Transparency Requirements: If your image contains transparent areas — such as portrait cutouts, logos, or stickers — PNG correctly retains those transparent channels. JPG does not support transparency.
- Design and Print Work: Designers working in Photoshop, Canva, Figma, or similar tools can open PNG files without any format issues, unlike HEIC which requires plugin support.
Why PNG is preferred over JPG for conversions
While JPEG is also widely supported, it is a lossy compression format. Every time you re-save a file as JPEG, some amount of image detail is permanently discarded. PNG uses lossless DEFLATE compression. When converting a high-fidelity iPhone photo to PNG, the output is guaranteed to match the decoded HEIC pixel-for-pixel — no artefacts, no blurring, no compression quality loss.
Common use cases for HEIC to PNG conversion
- Preparing iPhone photos for upload to SSC, RRB, UPSC, and other government exam portals
- Sharing images with Windows users who cannot view HEIC files natively
- Uploading product photos to e-commerce platforms that don't support HEIC
- Adding iPhone photos to presentations, Word documents, or Google Slides
- Archiving photos in a universally readable format for long-term storage
- Converting iPhone screenshots for use in design mockups and documentation

Frequently Asked Questions (FAQs)
HEIC stands for High Efficiency Image Container. It is a file format adopted by Apple starting with iOS 11 to save photos. It uses high-efficiency video coding (HEVC) to compress images, allowing them to take up half the storage space of JPEGs while maintaining similar visual quality.
Microsoft Windows does not include native decoder support for HEIC files out of the box. Users must install the "HEIF Image Extensions" and "HEVC Video Extensions" from the Microsoft Store, or convert the files to a widely supported format like PNG or JPG.
No. PNG is a lossless image format. Converting HEIC to PNG decodes the high-efficiency image and wraps it into a lossless container, ensuring all original details, colors, and quality parameters are preserved perfectly.
HEIC uses highly advanced, lossy compression algorithms designed specifically to minimize file sizes. PNG, on the other hand, is a lossless format that stores exact pixel data without compression artifacts. As a result, the PNG output is naturally larger in file size, but guarantees zero loss of quality.
Absolutely. Unlike other converters that upload your images to external servers, this tool processes everything directly inside your browser using JavaScript and WebAssembly. Your files never leave your computer or mobile device, offering 100% security and privacy.
Yes. This tool fully supports batch conversion. You can upload multiple files at once, convert them all in a single click, and download them individually or collectively as a ZIP archive.
Yes. The tool works on mobile browsers including Safari on iOS/iPadOS, and Chrome/Firefox on Android. No app installation or signups are required.
Yes. HEIC and HEIF are closely related formats — HEIF is the container standard and HEIC is Apple's specific implementation. Both .heic and .heif file extensions are supported and converted identically by this tool.
No. You can use the HEIC to PNG Converter instantly without creating an account, registering, or signing up.
Final Thoughts
HEIC is a great format for saving storage on your iPhone, but the moment you try to use those photos outside Apple's ecosystem — on Windows, in a browser, on an online form — the compatibility problems start. Converting to PNG once gives you a universally accepted, lossless file that works everywhere without plugins, extensions, or any further hassle.
This free HEIC to PNG Converter handles the conversion in bulk, entirely in your browser, with nothing uploaded to any server — so your personal photos stay private from start to finish.
