HEIC to PNG

Use HEIC to PNG to convert a supported HEIC or HEIF image into PNG format directly in your browser.

The tool processes one supported image file at a time and creates a PNG output from the image decoded by the browser-side HEIC/HEIF processing workflow.

The conversion changes the image format to PNG. It does not intentionally resize, crop, flip, or otherwise alter the image dimensions as part of the format-conversion workflow.

HEIC and HEIF files require decoding before their image pixels can be encoded into PNG format.

The current HEIC to PNG workflow uses a client-side HEIC/HEIF decoding library (heic2any), which utilizes a WebAssembly build of libheif to decode HEIC and HEIF image containers directly within your browser without requiring a server-side image-conversion service.

After decoding, the image is rendered onto an HTML5 Canvas and encoded into PNG format using browser-native APIs.

HEIC/HEIF decoding can require additional browser memory, particularly for large or high-resolution images.

The selected HEIC or HEIF file is decoded into image data using heic2any (libheif WebAssembly) and then rendered onto an HTML5 Canvas to encode into PNG format.

The generated PNG uses the decoded image dimensions and is not intentionally resized as part of the conversion.

PNG uses lossless raster encoding for the generated file, but converting an existing HEIC image does not restore quality or detail that was not present in the source.

Review the generated PNG when exact visual reproduction or file suitability is important.

PNG supports alpha transparency.

Where the decoded image contains transparent or semi-transparent areas, the current PNG output workflow does not composite those areas against an opaque background.

This allows transparent areas from the decoded image to be retained in the generated PNG.

HEIC to PNG is designed to create the PNG using the natural pixel dimensions of the decoded source image.

The conversion does not intentionally resize, upscale, downscale, or crop the image.

For example, if the decoded source image is 4032 × 3024 pixels, the PNG output is created using those decoded dimensions.

Use Resize Image separately if changing width or height is your main requirement.

HEIC and HEIF containers can contain information beyond the visible image pixels.

The current conversion workflow does not guarantee preservation of source metadata such as EXIF information, GPS data, capture dates, camera information, XMP data, or embedded color-profile metadata.

The image may appear in the expected visual orientation after decoding without the original orientation metadata being copied into the PNG.

Do not rely on the generated PNG to retain source metadata.

If metadata is important for your workflow, inspect the downloaded PNG before using it.

No specific file-size reduction is guaranteed.

HEIC/HEIF and PNG use completely different compression methods.

The generated PNG may be larger than the original HEIC file because PNG is a lossless format.

Converting to PNG should therefore be treated primarily as a format-compatibility conversion rather than a file compression operation.

Use Compress Image when controlling image file size is your main requirement.

HEIC to PNG converts a supported HEIC or HEIF source image into PNG format.

Compress Image is designed primarily for controlling image file size using its available compression workflows.

Use HEIC to PNG when PNG output is your main requirement.

Use Compress Image when reducing or targeting image file size is your main requirement.

HEIC/HEIF conversion performance can depend on the source file size, decoded pixel dimensions, image content, decoder implementation, available browser memory, browser environment, and device resources. A compressed HEIC or HEIF file can require substantially more memory after it is decoded into image pixels. Large or high-resolution photos can therefore require additional memory and processing time during HEIC/HEIF decoding, image preparation, canvas rendering where applicable, and PNG encoding. Performance may vary between browsers and devices.
