HEIC to PNG for Image Workflows
Fast, instant HEIC to PNG conversion. No signup required. Just drop your .heic file and get .png in seconds.
Batch Settings
HDR data will be tone-mapped
Your HEIC file may contain HDR (High Dynamic Range) data. PNG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Converting to PNG won't restore lost quality
Your HEIC file has already undergone lossy compression. Converting to PNG preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Animation frames will be lost
HEIC supports animation, but PNG does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your HEIC file may contain EXIF, XMP metadata. PNG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your HEIC file uses a wide color gamut (Display P3, sRGB). PNG uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — PNG is universally supported and will work everywhere.
还在为HEIC图片在不同设备上打不开、分享不便而烦恼吗？尤其是苹果手机拍出的HEIC格式，虽然文件小巧，画质优秀，但在微信、微博等常用社交平台分享时，或是上传到一些不支持HEIC的网站、游戏社区时，总是遇到各种障碍。这时候，将其转换为兼容性更广、几乎所有设备和应用都支持的PNG格式，就能省去许多麻烦。PNG不仅支持无损压缩，保留图片细节和色彩，还支持透明背景，让您的图片处理和分享变得更加顺畅。告别格式困扰，让您的精彩瞬间随时随地都能清晰呈现，无论是发给朋友、制作表情包，还是用在游戏攻略里，都能轻松搞定。
- 微信分享不失真
- 游戏截图转PNG
- 制作透明背景贴图
考虑到大陆、台湾和新加坡用户普遍使用微信进行图片分享，HEIC转PNG能有效避免因客户端兼容性问题导致的图片无法预览或显示异常。
About HEIC to PNG Conversion
Whether you're one of the many photographers, designers, and content creators who work with HEIC files daily, there comes a time when you need PNG instead. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG.
Here's a typical scenario: you receive a .heic file but your project, platform, or client requires .png. PNG uses lossless compression and supports transparency, making it perfect for graphics, logos, and screenshots. Rather than searching for desktop software or wrestling with command-line tools, you can convert HEIC to PNG online in seconds with CocoConvert.
This conversion is ideal when you Your HEIC file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts PNG uploads. The conversion helps you improve file compatibility across devices.
Your HEIC file may contain HDR (High Dynamic Range) data. PNG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost. Common misconception: ""Converting HEIC to PNG will improve the quality"" — in reality, no. heic has already permanently discarded data during compression. converting to png preserves what's left but cannot restore lost detail. the file will just be larger.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.

What Happens When You Convert HEIC to PNG
Your HEIC image is decoded into raw pixel data, then re-encoded as PNG. Current quality is preserved as-is — no further degradation.
Your HEIC file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using Portable Network Graphics's lossless compression
Metadata (EXIF, ICC profiles) is transferred where PNG supports it
The PNG file is saved and ready for download

Should You Convert HEIC to PNG?
When to Convert
- ✓Your HEIC file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts PNG uploads
- ✓You captured this file on iPhone 7+ (iOS 11+) and need to share it with others
- ✓You need a file that works in web browsers
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're hoping to improve image/audio quality — converting lossy to lossless cannot recover lost data
- ✗You want to preserve HDR information — PNG only supports standard dynamic range
Common Mistakes When Converting HEIC to PNG
"Converting HEIC to PNG will improve the quality"
No. HEIC has already permanently discarded data during compression. Converting to PNG preserves what's left but cannot restore lost detail. The file will just be larger.
"My animated HEIC will stay animated after conversion"
PNG does not support animation. Only a single frame will be saved. Use WebP or GIF to preserve animation.
