PNG to HEIC Converter

Convert large PNG images to compact HEIC files for photo storage when transparency is not required in the destination.

Shrink photographic PNG files with HEIC compression

PNG is excellent for lossless graphics, but photographic PNGs can be enormous. HEIC is a better storage format when the image is a photo and compatible software is available.

This conversion intentionally flattens transparency onto white because HEIC reader support for alpha varies. Logos and interface graphics are usually better kept as PNG, WebP or AVIF.

Transparency: Transparent PNG areas are flattened onto white. Keep PNG or choose WebP/AVIF if alpha transparency is essential.

What you get converting PNG to HEIC

Major photo savings

Photographic PNG files can become substantially smaller after HEIC encoding.

Simple RGB output

Transparent and palette images are normalized for predictable viewing.

Selectable quality

Adjust compression strength to suit previews, archives or device storage.

Source preserved

The PNG remains unchanged while a separate HEIC file is downloaded.

What to expect: The HEIC will usually be far smaller, but the conversion becomes lossy. Flat graphics and sharp text may show compression more readily than photographs.

When to convert PNG to HEIC

PNG to HEIC — frequently asked questions

It is placed on white because this converter writes predictable opaque HEIC output.

PNG stores pixels losslessly, while HEIC applies modern lossy photographic compression.

Usually not. PNG, WebP or AVIF better suit transparency and crisp graphic edges.

Yes. Use the quality slider from 1 to 100 before conversion.

Yes. Width and height are retained unless orientation metadata requires rotation.

Yes. Palette-based PNG input is decoded and normalized before HEIC encoding.

Who benefits from converting PNG to HEIC?

These are common examples; the right workflow depends on the file, required output, and your organization’s handling rules.

Apple device users

Prepare an efficient HEIC copy for compatible iPhone, iPad, and Mac workflows. A typical use is compressing lossless photo scans for a compatible archive.

Mobile content teams

Create smaller photo derivatives for storage and transfer in HEIC-aware systems. A typical use is reducing oversized PNG camera exports.

Photographers

Test a modern HEIC output while retaining the original editing master. A typical use is creating HEIC copies for storage on Apple devices.

App testers

Prepare sample HEIC assets for upload, preview, and compatibility checks. A typical use is the PNG remains unchanged while a separate HEIC file is downloaded..
