Compress PNG to HEIC for Smaller File Sizes
File sizes are 5–10x larger than JPEG for photographic content because lossless compression can't discard visual data. Converting to HEIC gives you a key advantage: roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences. HEIC is best for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss.
Why Convert PNG to HEIC?
File sizes are 5–10x larger than JPEG for photographic content because lossless compression can't discard visual data — converting to HEIC overcomes this by providing roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences
HEIC is the right choice when you need to: managing iphone photo libraries with reduced storage consumption
Gain broader compatibility — HEIC works with Apple devices (native since iOS 11 / macOS High Sierra), Windows 10+ (with HEVC extension), limited Android support
Reduce file size dramatically — 10 KB – 25 MB files compress to 1 MB – 8 MB with HEIC

How to Convert PNG to HEIC
Upload your PNG file
Drag your .png file onto the upload area or click to browse. We accept PNG files up to 50 MB.
Choose HEIC as output format
Select .heic (High Efficiency Image Container) from the format list. Adjust quality settings if needed — higher quality means larger file size.
Convert and download
Click Convert and wait for processing. Your HEIC file will be ready to download in seconds. The result is optimized for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss.
Frequently Asked Questions
Will I lose quality converting PNG to HEIC?
expand_more
Yes — HEIC uses lossy compression, which discards some data to achieve smaller files. Patent-encumbered (HEVC/H.265 licensing) and requires special codecs on Windows and older Android devices. For most practical purposes at high quality settings, the difference is imperceptible.
How large will my HEIC file be compared to the original PNG?
expand_more
PNG files are typically 10 KB – 25 MB, while HEIC files are typically 1 MB – 8 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted HEIC file?
expand_more
HEIC is compatible with: Apple devices (native since iOS 11 / macOS High Sierra), Windows 10+ (with HEVC extension), limited Android support.
What is the maximum file size I can convert?
expand_more
PureConverter accepts PNG files up to 50 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between PNG and HEIC?
expand_more
PNG (Portable Network Graphics) is best for screenshots, logos, ui elements, and any image requiring transparency or pixel-perfect accuracy. HEIC (High Efficiency Image Container) is best for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss. Key tradeoff: PNG's advantage is lossless compression with full alpha-channel transparency — every pixel is preserved exactly, while HEIC's advantage is roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences.
Pro Tips for PNG to HEIC Conversion
For the best HEIC quality, start with the highest-resolution PNG source available — lossy compression works better with more data to analyze
If your PNG file has transparency, make sure HEIC supports it — HEIC may not preserve alpha channels
HEIC works especially well for: converting ios photos to jpeg or png for cross-platform sharing
Did you know? When you AirDrop an HEIC photo to a non-Apple device, iOS silently converts it to JPEG on-the-fly before sending — most recipients never realize the conversion happened.
