Why ToFormat?
Superior Compression
HEIF compresses up to 50% better than JPG and often beats PNG in file size, especially for photos. Save storage without sacrificing quality.
Transparency Preserved
PNG’s full alpha channel is retained in HEIF (when using 32‑bit mode). Your logos and graphics stay transparent.
Apple Ecosystem
HEIF is the default format on iOS and macOS. Convert PNG to HEIF for seamless integration with Apple Photos and apps.
About the Formats
🖼️ What is PNG?
PNG (Portable Network Graphics) is a lossless raster format created in 1996. It supports full alpha transparency, 24‑bit color, and is widely used for web graphics, logos, and screenshots. PNG files can be large but preserve every pixel.

HEIF (High Efficiency Image File Format) is based on the HEVC video codec. Developed by MPEG, it's the default photo format on Apple devices since iOS 11. It offers up to 50% better compression than JPG, supports image sequences, depth maps, HDR, and transparency.

Upload PNG
Drag and drop your PNG files. You can upload up to 20 at once.
Choose settings
Select quality or lossless mode. HEIC (HEIF with HEVC) is the default output.
Download HEIF
Your HEIF files are ready. Download individually or as ZIP. Files auto-delete in 10 minutes.
When to Convert PNG to HEIF
📱 iPhone & iPad
HEIF is native on Apple devices. Convert PNG photos to HEIF for smaller camera rolls and faster syncing.
💡 For Android: try HEIF to PNG →📸 Professional Photography
HEIF supports 16‑bit color and HDR — ideal for photographers who need high dynamic range and efficient storage.
💡 Raw alternative: PNG to DNG →💾 Cloud Storage
Reduce storage costs. HEIF's superior compression means you store more photos in less space.
💡 For web: try PNG to WebP →🎬 Live Photos
HEIF can store image sequences. Convert multiple PNG frames to a single HEIF sequence (like Live Photos).
💡 Video alternative: PNG to MP4 →Format Comparison
| Format | PNG | HEIF |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | Yes | No |
| File Size | Larger | Smaller |
HEIF offers better compression but is less supported outside Apple devices. For universal compatibility, pair with HEIF to PNG or HEIF to JPG converters.
💡 Pro Tips
- HEIF with HEVC encoding (HEIC) is what Apple uses. Our converter produces standard HEIF files compatible with iOS/macOS.
- For lossless preservation of your PNG, enable lossless mode — the file will be slightly larger but pixel‑perfect.
- HEIF supports image sequences — convert animated PNG (APNG) to a single HEIF sequence (like Live Photos).
- Many Android devices now support HEIF too. Check compatibility before deploying.
- Use quality 80‑90% for a good balance — files will be much smaller than PNG with similar quality.
- HEIF also supports auxiliary images like depth maps — great for portrait mode edits.
- If your PNG contains ICC profiles, we preserve them in the HEIF output.
How PNG to HEIF Conversion Works
HEIF is a container format that can hold images compressed with HEVC (H.265) or other codecs. When you convert PNG to HEIF, our servers decode the PNG image (preserving all pixel data and alpha channel) and re‑encode it using the HEVC encoder (lossy or lossless), then package it in a HEIF container with metadata.
The result is a file that maintains high visual quality at a fraction of the size. For animated PNG (APNG), we create a HEIF image sequence (like Apple's Live Photos).
All processing is server‑side, and files are deleted after 10 minutes.
PNG vs HEIF: Which is Better?
Compression: HEIF typically beats PNG by 30‑50% at equivalent quality, especially for photographic content. Features: HEIF supports 16‑bit color, HDR, image sequences, depth maps — PNG does not (except APNG). Compatibility: PNG is universally supported; HEIF is native to Apple devices but requires browser support via JavaScript or fallbacks.
Choose HEIF for storage and Apple workflows, PNG for web delivery. Our converters help you switch as needed.
HEIF in the Apple Ecosystem
Since iOS 11 and macOS High Sierra, Apple uses HEIF as the default photo format. It saves about 50% space compared to JPG while retaining quality. Converting PNG to HEIF allows you to integrate web‑sourced images into your Apple photo library seamlessly, with transparency preserved.
For cross‑platform sharing, you might want to also keep a PNG copy. Explore our HEIF tools for more options.
