Convert PNG to HEIC Online

Convert PNG to HEIC - Complete Guide

Converting PNG to HEIC 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. HEIC is a high-efficiency image format commonly created by iPhone and iPad cameras. Below is what actually changes in a PNG→HEIC conversion, what is preserved, and when HEIC is the better choice than keeping PNG.

What changes when you convert PNG to HEIC

• HEIC 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: HEIC is typically more space-efficient than PNG for the same content.

About the PNG format

PNG (Portable Network Graphics) is a lossless image format that supports transparency. Our free PNG converter allows you to convert PNG files to JPG, WEBP, GIF, BMP, PDF, and many other formats. You can also convert any image format to PNG to take advantage of its transparency and lossless compression.

• Full name: Portable Network Graphics
• Developer: PNG Development Group
• Introduced: 1996
• Compression: Lossless (DEFLATE)
• Color depth: 24-bit (16 million colors) + 8-bit alpha
• Opens with: every browser, Photoshop, GIMP, Figma

Where PNG is strong: lossless quality with no compression artifacts; full alpha transparency; crisp text, screenshots, and line art.

Typical PNG uses: screenshots, logos and UI graphics, images that need transparent backgrounds.

About the HEIC format

HEIC (High Efficiency Image Container) is Apple's default photo format for iPhone and iPad. Our free HEIC converter allows you to convert HEIC/HEIF photos to universally compatible formats like JPG, PNG, and WEBP without installing any software.

• Full name: High Efficiency Image Container
• Developer: MPEG (used by Apple)
• Introduced: 2017 (iOS 11)
• Compression: Lossy (HEVC)
• Color depth: 10-bit HDR capable
• Opens with: Apple Photos, macOS, iOS

Where HEIC is strong: roughly half the size of JPG at similar quality; stores high-dynamic-range detail from modern phones.

Typical HEIC uses: iPhone and iPad photos, saving storage space on Apple devices.

What HEIC keeps

• Transparency / alpha channel is carried over.
• Image dimensions (width and height in pixels) stay the same unless you resize.
• HEIC adds: roughly half the size of JPG at similar quality.

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 HEIC limitation to keep in mind: limited support outside Apple devices.

When to convert PNG to HEIC

• Convert PNG to HEIC for iPhone and iPad photos.
• Convert PNG to HEIC for saving storage space on Apple devices.
• Pick HEIC when you need stores high-dynamic-range detail from modern phones.
