Why convert HEIC to PNG?

HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads since iOS 11. It uses HEVC compression to produce files 40–50% smaller than JPG. However, HEIC is not supported on Windows, most Android devices, many web platforms, or older macOS versions.

PNG is a lossless format supported universally — every browser, operating system, and image editor handles PNG without issues. Converting HEIC to PNG preserves the full image quality without any compression artifacts. PNG also supports alpha transparency.

PNG files will be larger than the original HEIC because PNG does not use lossy compression. If file size matters more than lossless quality, consider converting to JPG or WebP instead.

All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.

How to convert HEIC to PNG

Upload your HEIC file
Drag and drop your HEIC image onto the converter area or click to browse your device. You can add multiple files at once for batch conversion.
Click Convert
PNG is lossless, so there is no quality slider: every pixel goes into the file unchanged and transparency stays.
Download PNG
The Download button next to a file saves it on its own, and Download all packs all finished files into one ZIP archive. With a single finished file no archive is made, the file downloads directly.

When should you convert HEIC to PNG?

Website optimization
HEIC photos from iPhone cannot be displayed in most web browsers. Converting to PNG creates universally compatible, lossless images that preserve full quality and transparency for web graphics and editing.
Email and sharing
PNG files are universally accepted by email clients like Gmail, Outlook, and Apple Mail. Converting HEIC to PNG ensures your iPhone photos can be shared without compatibility issues on any device or platform.
Further editing
PNG opens in every graphics editor and stores pixels without loss, so further saves do not degrade the image.
Documents and archival
PNG is a lossless format ideal for archival storage and professional editing. Converting HEIC photo libraries to PNG preserves every pixel and ensures long-term compatibility with all image editors and operating systems.

What makes this HEIC to PNG converter different?

Complete privacy
Your HEIC files are processed entirely in your browser. Nothing is uploaded to any server – your images stay on your device at all times.
Many files at once
Add any number of HEIC files, each up to 100 MB. The converter processes them one by one and shows the status of each.
Size before and after
Next to every file you see the input and output size, and under the list the total for the whole queue, so you know at once how much a file grew or shrank.
Download in one archive
The Download all button packs all finished files into one ZIP archive, so you do not have to approve a dozen downloads one after another.

What to expect when converting HEIC to PNG?

HEIC uses lossy HEVC compression while PNG is a lossless format. The conversion decodes the HEIC data and saves every pixel exactly as-is in PNG. No additional quality loss occurs during conversion.

PNG files will be significantly larger than the original HEIC — a 2 MB HEIC photo may become 8–15 MB in PNG. This is expected because PNG stores all pixel data without lossy compression.

If file size is a concern, consider converting to JPG (lossy, much smaller) or WebP (modern, smaller than both) instead. PNG is the right choice when you need lossless quality and universal compatibility.

How much does a file weigh after converting HEIC to PNG?

Three 1440 × 960 pixel photos from the HEIF test set published by Nokia went through the converter at the default settings: an autumn forest by the water, a city street at night and a crowd on a sunlit street. Sizes are given exactly as the tool counts them: kilobytes and megabytes of 1024.

File	Dimensions in pixels	HEIC	PNG	Change
Autumn forest by the water	1440 × 960	286.7 KB	3.32 MB	11.9 times larger
City street at night	1440 × 960	40.4 KB	1.63 MB	41.2 times larger
Crowd on a street	1440 × 960	127.3 KB	2.19 MB	17.6 times larger

Our own measurement from 6 September 2026 in a Chromium-based browser. PNG stores every pixel without loss, so every photo grows more than tenfold regardless of how tightly it was packed in HEIC.

Frequently asked questions about HEIC to PNG conversion

Is converting HEIC to PNG free?

Yes, this HEIC to PNG converter is completely free with no limits. You can convert as many files as you need without registration or watermarks.

Does the converter upload my files to a server?

No. All processing happens locally in your browser using JavaScript and Canvas API. Your files never leave your device, ensuring complete privacy and security.

Will I lose quality when converting HEIC to PNG?

No. PNG stores every pixel without loss, so the result looks exactly like the image read from the HEIC file. Detail lost earlier when HEIC was saved is not recovered by the conversion.

Can I add transparency when converting HEIC to PNG?

PNG stores an alpha channel, so transparent and semi-transparent areas of the HEIC file stay unchanged in the result.

Can I convert multiple HEIC files at once?

Yes, the converter supports batch conversion. You can add multiple HEIC files and convert them all to PNG simultaneously. Use the batch download option to save all converted files at once.

Why can't I open HEIC files on my Windows PC?

HEIC is Apple's proprietary image format used by iPhones and iPads. Windows doesn't natively support HEIC without additional codecs. Converting HEIC to PNG solves this compatibility issue, allowing you to view and share your photos on any device.

What is the maximum file size?

Each file may be up to 100 MB; a larger one stops on the list with a message that it is too large. The number of files in the queue is not limited, and large images take longer because the browser decodes them fully into memory.

Does the converter work on mobile devices?

Yes, the converter works on any device with a modern web browser, including smartphones and tablets. The interface adapts to your screen size for a comfortable experience on any device.

How do I download all files at once?

The Download all button packs the finished files into one ZIP archive named heic-png.zip. With a single finished file no archive is made and the file downloads directly.
