Convert PNG to HEIC
Enconvert converts your PNG image to Apple HEIC format in under 5 seconds. The output file is significantly smaller than the original PNG while preserving visual quality. HEIC compression is far more efficient than PNG for photographic content. No settings to configure.

Why Convert PNG to HEIC?
PNG files use lossless compression, which preserves every pixel but results in large file sizes — a typical 12-megapixel photo can be 10–15 MB as PNG. HEIC uses advanced HEVC compression to dramatically reduce file sizes while maintaining excellent visual quality, making it the most storage-efficient photo format available on Apple devices.
Massive file size reduction. Converting PNG to HEIC can reduce file size by 70–90% for photographic images. A 10 MB PNG photo typically becomes 1–3 MB as HEIC with minimal visible quality loss. This compression efficiency is the primary reason Apple adopted HEIC as the default photo format.
Apple ecosystem integration. HEIC is the native photo format on iOS and macOS. Converting PNG images to HEIC allows them to integrate seamlessly with iCloud Photo Library, Apple Photos, and other Apple applications. The files follow the same format as photos taken directly by the iPhone camera.
10-bit color depth. HEIC supports 10-bit color (over 1 billion colors) compared to the standard 8-bit color used in most PNG files. This wider color gamut produces smoother gradients and more accurate color reproduction, particularly noticeable in sky scenes, sunsets, and subtle color transitions.
Transparency preserved. Like PNG, HEIC supports alpha channel transparency. When converting a PNG with a transparent background, the transparency is preserved in the HEIC output. This makes HEIC a viable replacement for PNG in workflows where transparency is required.
When to keep PNG instead: If the images need to be shared with Windows, Linux, or Android users, or displayed on the web, keep them as PNG. HEIC support outside the Apple ecosystem remains limited. PNG is also the better choice for screenshots, UI elements, and graphics with sharp text where lossless quality is essential.
Enconvert handles PNG-to-HEIC conversion server-side using high-quality HEVC encoding. The free tier supports 100 conversions per month with no sign-up required.

Frequently Asked Questions
HEIC files are typically 70–90% smaller than PNG files for photographic content. A 10 MB PNG photo can compress to 1–3 MB as HEIC. The compression ratio depends on image content — photos with smooth gradients compress especially well, while images with sharp edges and fine detail see somewhat less reduction. Even in the worst case, HEIC is significantly smaller than PNG.
Yes. HEIC supports alpha channel transparency, so PNG images with transparent backgrounds maintain their transparency in the HEIC output. This makes HEIC a viable alternative to PNG for images that require transparent areas, such as logos and icons used within the Apple ecosystem.
When using lossy HEIC compression, there is a small quality reduction compared to the lossless PNG original. However, HEIC compression is extremely efficient — the quality loss is imperceptible for photographs and most practical uses. HEIC also supports lossless compression mode, which preserves every pixel exactly like PNG while still achieving smaller file sizes.
The free tier accepts PNG files up to 5 MB with 100 conversions per month — no sign-up or credit card required. The Starter plan ($19/mo) supports 2,000 conversions with 15 MB file limits, the Pro plan ($49/mo) supports 10,000 conversions with 50 MB limits, and the Business plan ($149/mo) supports 50,000 conversions with 150 MB limits.
Yes. The Enconvert API supports programmatic PNG-to-HEIC conversion in any quantity. This is useful for migrating image libraries to HEIC format for Apple device storage optimization. Send PNG files via the REST API and receive HEIC output. Integration examples are available in Python, JavaScript, and cURL.
