How to Convert PNG to HEIF

  1. Upload your PNG images by dragging and dropping or clicking the upload area. You can select up to 10 files at once for batch conversion.
  2. Adjust quality settings: Choose a quality level from 50-95% for optimal balance between file size and visual quality.
  3. Select color depth: Use 8-bit for standard images or 10-bit for HDR content with wider color gamut.
  4. Optional resize: Enable resizing to reduce dimensions during conversion for even smaller files.
  5. Convert and download: Click convert and download individual files or all as a ZIP archive.
Pro tip: Use our PNG Analyzer to check your image properties first. For web use, consider PNG to WebP for broader browser support.

PNG vs HEIF Comparison

PNG

Lossless compression with universal support across all browsers and devices. Best for graphics, logos, screenshots, and images requiring transparency. Larger file sizes compared to modern formats. Use our PNG compressor to reduce sizes while keeping the format.

HEIF

Modern format using HEVC compression, developed by the MPEG group. Offers 40-50% smaller files than PNG with similar quality. Supports transparency, HDR, 10-bit color, and image sequences. Native support on Apple devices (iOS 11+, macOS High Sierra+). For older devices, convert back using HEIC to JPG.

Why Choose HEIF Format?

Superior Compression

HEIF achieves 40-50% smaller file sizes compared to PNG while maintaining excellent visual quality.

Transparency Support

Unlike JPEG, HEIF fully supports alpha channels for transparent backgrounds.

HDR & Wide Color

Supports 10-bit and 12-bit color depths with HDR for professional-grade imagery.

Apple Device Native

Default format for iPhone photos. Perfect for iOS and macOS applications.

Quality Settings Guide

85-95%

High quality with excellent compression. Ideal for photos, detailed images, and professional use. Virtually indistinguishable from the original PNG.

70-84%

Good balance between quality and file size. Perfect for most use cases including sharing, storage, and general applications.

50-69%

Noticeable compression with very small files. Use for thumbnails, previews, or when storage space is critical. Consider our Image Resizer for additional size reduction.

Frequently Asked Questions

HEIF (High Efficiency Image Format) is the container format, while HEIC is the file extension Apple uses for HEIF files encoded with HEVC compression. They are essentially the same format. Our converter produces standard HEIF/HEIC files compatible with all supporting devices and software.

Yes! Unlike JPEG, HEIF fully supports alpha channels for transparency. When you convert a PNG with transparent areas, the transparency is preserved in the HEIF output. This makes it great for logos, icons, and graphics with transparent backgrounds.

HEIF is natively supported on iOS 11+, macOS High Sierra+, Windows 10 (with extension), and Android 9+. For broader web compatibility, consider using WebP or AVIF formats instead. To convert HEIF back for older devices, use our HEIC to JPG converter.

For most purposes, 80-90% quality offers an excellent balance. For photos and detailed images, use 85-95%. For graphics with solid colors, 70-80% often works well. HEIF's efficient compression means even lower quality settings look good compared to older formats.

Use 10-bit for HDR content, professional photography, or images with subtle gradients where banding might occur with 8-bit. 10-bit provides over 1 billion colors compared to 16.7 million with 8-bit. For standard images and photos, 8-bit is usually sufficient and produces smaller files.

Each file can be up to 20MB in size, and you can upload up to 10 files at once for batch conversion. For larger files, consider using our Image Resizer to reduce dimensions first, or compress your PNG before converting.

Files are temporarily stored only during the conversion process and are automatically deleted within 24 hours. We don't keep copies of your images or use them for any other purpose. Your privacy is important to us.
