HEIC
High Efficiency Image Container自 iOS 11 起，iPhone 預設拍攝的照片格式——在相同畫質下，檔案大小大約是 JPEG 的一半，並支援景深地圖與即時影像（Live Photos）。Windows 與多數網站至今仍無法開啟它，這也是為什麼轉成 JPG 是需求量最大的圖片轉換。

PNG
Portable Network Graphics具備真正 Alpha 透明色版的無損壓縮格式，最初是作為 GIF 的免費替代品而誕生。非常適合用於標誌、螢幕截圖與邊緣銳利的介面美術；用在照片上則相當浪費，因為 JPEG 或 WebP 的檔案大小只會是它的一小部分。

- HEIC is lossy and PNG is lossless. Re-saving cannot recover details removed by the lossy source. The output is usually larger with similar visible quality, not a repaired original.
關於 HEIC 轉 PNG 的常見問題
這個 HEIC 轉 PNG 轉換器是免費的嗎？
是的。在這裡把 HEIC 轉換為 PNG 完全免費，不需要帳號、沒有浮水印，也沒有每日次數限制。處理在你自己的裝置上完成，因此沒有需要轉嫁給你的伺服器成本。
我的 HEIC 檔案會被上傳到任何地方嗎？
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
HEIC 轉 PNG 有檔案大小限制嗎？
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
把 HEIC 轉換為 PNG 會損失品質嗎？
Nothing is intentionally discarded in this step, because PNG is lossless. A HEIC file encoded with lossy settings stays lossy, so missing detail is not recovered.
可以一次把多個 HEIC 檔案轉換為 PNG 嗎？
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
HEIC 轉 PNG 能在手機、Mac 或 Chromebook 上使用嗎？
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
