Create a compact HEIC image

HEIC provides efficient compression for modern devices, photo libraries, backups, and storage-conscious workflows.

Professional PNG to HEIC Converter

Upload a genuine PNG image and convert it to HEIC using a configured server encoder or conversion API.

HEIC encoding is unavailable: configure CLOUDCONVERT_API_KEY or a working local HEIC encoder.

Upload PNG

When a local HEIC encoder is available, conversion runs on this server. Otherwise, a configured CloudConvert API may process the PNG remotely. Local results are removed after 24 hours on a later visit to this page.

0 KB HEIC Size

This tool needs a working HEIC encoder (HEIC-enabled Imagick or heif-enc with an HEVC codec) or a configured CloudConvert API. HEIC output is checked for a valid HEIC container; JPEG/PNG files renamed to .heic are rejected.

Why Convert PNG to HEIC?

Convert a PNG image into a smaller HEIC file for modern photo libraries, mobile devices, backups, and storage-efficient workflows.

Secure PNG Validation

The tool checks the standard PNG file signature before accepting the uploaded image.

HEIC Photo Compression

HEIC uses modern compression to reduce file size while retaining strong visual quality.

What Is PNG to HEIC Conversion?

PNG is a lossless image format widely used for graphics, screenshots, transparency, and web content. It preserves image detail but can produce large files, especially for photos.

HEIC is a High Efficiency Image Container format designed to store high-quality images in smaller files on compatible devices and software. Converting PNG to HEIC can reduce file size, but compatibility is more limited than PNG.

Image Property	PNG Source	HEIC Output
Compression	Lossless DEFLATE compression	Typically lossy HEVC compression
Browser compatibility	Widely supported	Support varies by browser and operating system
Transparency	Supported by PNG	Depends on encoder and compatible viewer
Typical file size	Often larger for photographs	Can be smaller for photos; not guaranteed

How It Works

Convert PNG to HEIC in three straightforward steps.

1. Upload PNG

Select a genuine PNG image or drag and drop it into the upload area.

2. Convert Securely

A configured server HEIC encoder is used when available. Otherwise the PNG is sent to CloudConvert if the API is configured.

3. Preview and Download

The returned HEIC container signature is validated before the download button appears.

PNG to HEIC Converter FAQs

Common questions about PNG transparency, HEIC quality, transparency, metadata, and server requirements.

It converts a PNG image into a compact HEIC High Efficiency Image Container file.

Yes. The tool validates the HEIC container and compatible brand before showing the download button.

HEIC typically uses lossy compression, so some quality change is possible. For logos and text graphics, keeping the original PNG may be preferable.

Often yes. HEIC is designed for efficient storage, while PNG uses lossless compression and may create a significantly larger file.

PNG supports alpha transparency, but HEIC transparency retention depends on the encoder and viewing software. Check the resulting HEIC before relying on alpha.

Metadata may not carry over from PNG to HEIC. The primary conversion target is the image itself, not EXIF, text chunks or color profile metadata.

Not when using a configured CloudConvert API. For local conversion you need a working HEIC-enabled Imagick extension or the heif-enc CLI with exec enabled.
