What changes when you convert HEIC to PNG
- PNG stores pixels losslessly, so no additional detail is lost — but it cannot restore detail that HEIC compression already discarded, and the file usually gets bigger.
- Transparency is preserved: PNG supports an alpha channel, so transparent backgrounds from HEIC stay transparent.
- PNG is less space-efficient than HEIC, so expect the converted file to be larger than the original.
- Compatibility improves: PNG opens in more browsers, apps and operating systems than HEIC.
- HEIC is the default photo format on iPhones and iPads. Converting it avoids the "unsupported file" errors common on Windows, Android and many websites.
About HEIC
HEIC is Apple's name for HEIF images compressed with HEVC (H.265). It is the default photo format on iPhone and iPad, storing photos at roughly half the size of an equivalent JPG.
- Best for
- Photos taken on Apple devices and stored in iCloud Photos.
- Strengths
- Small files with high quality, 10-bit color, depth and Live Photo data.
- Limitations
- Poor support outside Apple devices: many Windows apps, Android devices and websites cannot open it.
About PNG
PNG (Portable Network Graphics) is a lossless raster format created as a patent-free replacement for GIF. It supports full alpha transparency and up to 16 bits per channel.
- Best for
- Screenshots, logos, UI graphics, diagrams and any image that needs a transparent background or pixel-perfect edges.
- Strengths
- Lossless quality, full transparency, opens everywhere.
- Limitations
- Photos produce large files compared with JPG, WebP or AVIF.
Frequently asked questions
Is the HEIC to PNG conversion really free?
Yes. ConverterUp is fully free, with no signup, no watermarks, and no daily quota for the HEIC to PNG converter. We support the project through unobtrusive ads.
Are my HEIC files uploaded to a server?
No. Conversion runs in your browser using WebAssembly. The HEIC bytes never leave your device, and we have no upload endpoint at all.
What is the maximum file size?
For HEIC input, the soft cap is 50 MB for images and 500 MB for video. Practical performance depends on your device's RAM.
Does converting HEIC to PNG reduce quality?
No further quality is lost, because PNG is lossless. The file will not look better than the HEIC source, though, and it will usually be larger.
Does PNG keep the transparent background of my HEIC?
Yes. PNG supports a full alpha channel, so transparency from the HEIC file is preserved.
