PNG to HEIC Converter — Complete Guide

PNG is widely used for lossless image compression with full alpha transparency support, making it the standard for web graphics, logos, and screenshots. HEIC is Apple's modern format based on HEVC compression, offering roughly double the compression efficiency of JPEG and significantly better compression than PNG for photographic content. Converting PNG to HEIC can dramatically reduce storage requirements while maintaining transparency.

For Apple ecosystem users, HEIC is the native image format — iPhones have captured photos in HEIC by default since iOS 11. Converting your PNG images to HEIC creates consistency across your photo library while taking advantage of HEIC's superior compression and full feature set including transparency, 16-bit color depth, and multi-image storage.

Why Convert PNG to HEIC?

Storage optimization is the primary motivation. PNG files, especially large photographs or high-resolution graphics, can be quite large. HEIC can reduce these file sizes by 50-70% while maintaining comparable visual quality and preserving alpha channel transparency. For iPhone and iPad users with extensive image libraries, the cumulative storage savings from converting PNG to HEIC can be substantial.

Unlike converting to JPEG which loses transparency, HEIC fully preserves alpha channel transparency from your PNG files. This makes HEIC uniquely suitable as a space-saving replacement for PNG images with transparent backgrounds, such as logos, icons, and UI elements used in Apple ecosystem applications.

File Size Considerations

Because all conversion happens locally in your browser, there is no fixed server-side upload limit. Very large files may be limited by your device's available memory and browser capabilities. For best results with very large PNG files, ensure your device has sufficient free memory before starting the conversion.

HEIC Compatibility Considerations

HEIC is natively supported on Apple devices (iOS 11+, macOS High Sierra+) and has growing support on other platforms. Windows 10/11 support HEIC with free extensions from the Microsoft Store. Android 9+ supports HEIC natively. However, for maximum cross-platform compatibility, you may want to keep PNG originals alongside HEIC conversions.

FAQ

Frequently Asked Questions — PNG to HEIC

Everything you need to know about converting PNG images to HEIC format.

Why convert PNG to HEIC?

HEIC offers superior compression compared to PNG, typically reducing file sizes by 50-70% for photographic content. This saves significant storage space on Apple devices and iCloud while maintaining excellent quality.

Does converting PNG to HEIC lose quality?

HEIC uses lossy compression by default, so some quality loss may occur. However, at high quality settings the visual difference is virtually imperceptible. PNG's lossless quality can be preserved by using HEIC's lossless mode.

Does HEIC support transparency like PNG?

Yes, HEIC fully supports alpha channel transparency just like PNG. Your transparent PNG images will retain their transparency when converted to HEIC format.

Is HEIC better than PNG?

For photographs, HEIC offers dramatically smaller file sizes than PNG with comparable quality. For graphics with text and sharp edges, PNG's lossless compression may be preferable if file size isn't a concern.

Can Windows and Android open HEIC files?

Windows 10/11 support HEIC with the free HEIF Image Extensions from the Microsoft Store. Android 9+ supports HEIC natively. However, compatibility is not as universal as PNG.

Is PNG to HEIC conversion good for iPhones?

Yes, HEIC is the native camera format on iPhones. Converting PNG to HEIC optimizes images for the Apple ecosystem, reducing storage usage and ensuring seamless integration with Photos and iCloud.

Is there a file size limit for PNG to HEIC conversion?

There is no fixed server-side upload limit since all processing happens locally in your browser. Very large files may be limited by your device's available memory and browser capabilities.

Is PNG to HEIC conversion free?

Yes, completely free. Our PNG to HEIC converter has no hidden costs, no registration requirements, and no limits on the number of files you can convert.

Are my files secure during conversion?

Yes, 100% secure. All conversion happens locally in your browser. Your PNG files never leave your device and are never uploaded to any external server.
