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.
iPhoneで撮った写真がHEIC形式のまま送れなくて困った経験、一度はあるのではないでしょうか。取引先へのメール添付、同人誌の入稿データ、SNSへの投稿——いざ使おうとした瞬間に「このファイルは開けません」と表示される、あの気まずさ。PNGに変換しておけば、相手の環境を気にせず使い回せます。このツールはアップロードするだけで変換が完了するので、専用ソフトは不要です。画質を落とさず透過情報も保持したまま書き出せるため、加工素材としてもそのまま使えます。
- 同人誌・コミケ入稿データの形式統一
- 取引先や印刷会社へのビジネス資料送付
- 縦書きレイアウト用のトリミング・加工前処理
日本の印刷所やDTP環境ではHEICの受け入れに対応していないケースがまだ多く、入稿時にPNG変換を指定される場合があります。特に同人誌印刷会社の入稿規定ではPNG・TIFF・PSDが標準とされていることがほとんどです。
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.
How to Convert HEIC to PNG

Drop your file
Drag your .heic file onto the converter. Need to process many files? Add up to 5 at once (100 for Pro).
- 2
Set output to PNG
Pick PNG from the format list. The converter automatically tunes settings for the HEIC→PNG pair.
- 3
Hit Convert
Processing happens server-side — your browser stays responsive. Most image files convert in under 10 seconds.
- 4
Download and use
Your .png file is ready to plug into your workflow. Download it or share the link (expires in 24 hours).
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.
Frequently Asked Questions
Who needs to convert HEIC to PNG?
This conversion is commonly used by photographers, designers, and content creators. Typical reasons include improve file compatibility across devices and ensuring compatibility with downstream tools or platforms.
Can I convert HEIC to PNG without losing quality?

Do I need to install software to convert HEIC to PNG?
No. CocoConvert runs entirely in your browser — no downloads, no plugins. It works on macOS, Windows, Linux, iOS, and Android.
How many HEIC files can I convert at once?
Free users can convert up to 5 files per hour. Pro subscribers get 100 files per hour with larger size limits (5 GB per file). Business API users can integrate batch conversion directly into their tools.
Is there an API for HEIC to PNG conversion?
Yes. CocoConvert offers a Business API for automated conversions. It supports all the same format pairs available in the web interface, including HEIC to PNG.
