Convert HEIC to PNG
Drop HEIC files and download them as PNG. PNG supports transparency but HEIC files have none, so the output is fully opaque; use the crop or background tools if you need cut-outs. Conversion runs on your device, so large batches finish in seconds and nothing is uploaded.
How to use the HEIC to PNG
- Drop or paste your HEIC files (up to 200).
- No settings needed: the output is lossless.
- Click Convert to PNG.
- Download each file or all as a ZIP.
Why convert HEIC to PNG?
HEIC is the default photo format on iPhone and iPad. It stores photos at roughly half the size of JPEG, but Windows, many websites, forms and older Android phones cannot open it, so conversion is often the only way to share.
PNG is lossless and supports full transparency, which makes it the standard for logos, screenshots, diagrams and anything with sharp edges or text. Photos saved as PNG are large.
What changes in the conversion
PNG is lossless, so nothing further is lost in the conversion, but the HEIC compression already applied cannot be undone; the PNG file will be much larger without being sharper. PNG supports transparency but HEIC files have none, so the output is fully opaque; use the crop or background tools if you need cut-outs.

How it works on your device
Your browser decodes the HEIC file into raw pixels using a WebAssembly build of libheif, because browsers cannot open HEIC natively, draws them onto a canvas and asks its built-in encoder to write PNG. Nothing is sent to a server, which is why there is no file-size limit beyond your device's memory and no queue.
