Convert HEIC to PNG

What Does the HEIC to PNG Converter Do?

This tool converts Apple-format HEIC and HEIF images directly in the browser to lossless PNG. Unlike JPG conversion, PNG stores no compression artifacts — the output file represents the input image as accurately as possible. Ideal for all applications where image quality and pixel accuracy are absolute priorities.

PNG or JPG — When to Use Which Format?

The choice between PNG and JPG when converting HEIC depends on the intended use:

Choose PNG when:

• The image will be further edited after conversion (multiple processing steps without artifact accumulation)
• Transparency is needed (PNG alpha channel; JPG doesn’t support transparency)
• Text in the image must be rendered sharply (screenshots, scans)
• The image will be used as an asset in a design project
• Pixel-accurate reproduction is more important than compact file size

Choose JPG when:

• The image is shared via email or chat (compact file size)
• The image is embedded on a website (fast load times)
• It’s a photo without transparency (JPG is more efficient for photos)
• Storage space or transfer volume is limited

How Does the HEIC-to-PNG Conversion Work Technically?

The conversion process runs in four steps in the browser:

1. EXIF Analysis: Before decoding, an EXIF parser reads the orientation information and optionally other metadata from the HEIC file.

2. HEIC Decoding: Safari (iPhone, Mac) uses the native browser capability for HEIC decoding. All other browsers use a decoding library running in the browser via WebAssembly.

3. Canvas Processing: The decoded image is drawn onto an HTML Canvas element. Orientation correction and optional scaling happen here.

4. PNG Export: canvas.toBlob('image/png') exports the result as lossless PNG. No external library is needed for export — this is a native browser function.

How Large Are PNG Files and How Long Does Conversion Take?

PNG is a storage-intensive format for photos. A typical 12-megapixel iPhone photo results in a PNG file of 15–25 MB. For comparison: as HEIC 1.5–2 MB, as JPG (quality 85) 3–5 MB.

This has practical implications:

• Batch processing: With many high-resolution photos, browser processing can take considerable time. Recommendation: reduce resolution to “Full HD” or “4K”.
• ZIP download: 100 HEIC photos as PNG can result in a ZIP archive of 1–2 GB. Ensure sufficient storage space is available.
• Web design use: PNG for websites should be as small as possible. Consider further optimization with a PNG optimization tool after HEIC-to-PNG conversion.

How Do I Use PNG Transparency After Conversion?

PNG supports a true transparency channel (alpha) as one of the few formats. HEIC photos contain no transparency by default — all pixels are opaque. However, conversion to PNG lays the groundwork for a typical workflow:

1. HEIC → PNG (with this tool)
2. PNG → Remove background (with the Background Remover tool)
3. PNG with transparent background → continue processing in Photoshop, Figma, GIMP

This workflow is especially relevant for product photography: iPhone photos of products often against a white background, followed by background removal for shop integration.

What Happens to EXIF Data with PNG Output?

PNG has a technically different metadata structure than JPEG. While JPEG has a standardized EXIF APP1 section, PNG stores metadata in tEXt and iTXt chunks without a unified standard for EXIF data.

In practice this means:

• Capture date and camera model are stored in PNG metadata (where technically possible)
• GPS data is always removed for privacy reasons — there is no universal EXIF GPS standard for PNG
• Orientation is physically corrected in the pixel matrix, not as a metadata tag

What Are the Best Use Cases for HEIC to PNG?

UI design and mockups: Exporting iPhone screenshots in HEIC format for Figma or Sketch — PNG is the standard import there, pixel-accurate display is important.

Product photography: Exporting iPhone product photos as PNG, followed by background removal for transparent backgrounds on Shopify or WooCommerce.

Scientific documentation: Screenshots of measurement curves, diagrams, or microscope images — JPG artifacts could be misinterpreted as measurement noise; PNG avoids this.

Quality-conscious archiving: When HEIC photos should be stored long-term in a format readable by all common programs without introducing further quality losses.

QR codes and text documents: A photo of a QR code or document as PNG is sharper than JPG at comparable output size.
