Convert PNG to HEIF - Complete Guide

Converting PNG to HEIF stays in the raster image family but changes the traits that decide size, quality, transparency, editability, or device support. PNG is a lossless image format commonly used for screenshots, transparent graphics, logos, and high-quality web images. HEIF is a image format. High efficiency format. Below is what actually changes in a PNG→HEIF conversion, what is preserved, and when HEIF is the better choice than keeping PNG.

What changes when you convert PNG to HEIF

• HEIF uses lossy compression, so the converter re-encodes the file and drops some fine detail to reduce size. At high quality the difference is hard to notice, but it cannot be undone.
• Expect a smaller output file: HEIF is typically more space-efficient than PNG for the same content.

• Image dimensions (width and height in pixels) stay the same unless you resize.
• HEIF adds: high quality at small file sizes.

Things to watch out for

• Keep your original PNG if you may need to re-edit or re-export later — repeated lossy saves accumulate quality loss.
• One HEIF limitation to keep in mind: limited support outside Apple devices.

When to convert PNG to HEIF

• Convert PNG to HEIF for modern phone photos.
• Convert PNG to HEIF for space-efficient photo storage.
• Pick HEIF when you need stores rich photo metadata.
