PNG to HEIC converter
Free online PNG to HEIC converter
Convert PNG images to HEIC (High Efficiency Image Coding) format directly in your browser. While PNG uses lossless DEFLATE compression that often results in large files—especially for high-resolution screenshots, UI assets, and photographs—HEIC uses HEVC (H.265) intra-frame coding to store images at roughly a fraction of the PNG file size while retaining full 8-bit alpha channel transparency.
PNG vs. HEIC technical comparison
| Property | PNG | HEIC (HEIF) |
|---|---|---|
| Compression codec | Lossless DEFLATE (LZ77 + Huffman) | HEVC / H.265 intra-frame (lossy or lossless) |
| Alpha transparency | Supported (8-bit / 16-bit RGBA) | Supported (auxiliary alpha plane) |
| Typical file size | Large for photos and complex gradients | 50–75% smaller at quality 85 |
| Color depth | Up to 16-bit per channel | Up to 10-bit / 12-bit HDR support |
| Primary ecosystem | Universal web and desktop support | Apple iOS, macOS, iPadOS, Android 10+, Windows 11 |
How to convert PNG to HEIC
- Select a PNG file from your device or paste a direct image URL and click Upload!.
- Adjust the HEIC quality factor slider (1–100, default 85). Settings between 80 and 92 keep sharp edges and smooth alpha masks while significantly cutting file size; 100 uses minimal quantization.
- Click Convert to HEIC! and download the output
.heicfile.
