What to expect when converting HEIC to PNG

Typical file-size change

5–10× larger

Example

A 2 MB iPhone HEIC photo typically becomes 10 – 20 MB as PNG.

Quality: Lossless once decoded. PNG preserves the HEIC pixels at full fidelity.

Best for: editing photos in software that doesn't support HEIC.

Avoid when: compactness matters — PNG is much larger than HEIC.

Tip: PNG is overkill for most iPhone photos. Convert to JPG unless you specifically need lossless or transparency.

HEIC to PNG: maximum quality from iPhone photos

Converting HEIC to PNG decodes the HEVC-compressed image data and stores every decoded pixel losslessly. Unlike HEIC-to-JPG (which re-compresses with a second lossy codec), HEIC-to-PNG preserves the decoded quality without any additional loss. The file will be significantly larger (often 10-20×) but represents the highest quality extraction possible from the HEIC source.

Choose PNG over JPG when the iPhone photo will be heavily edited (each lossless save avoids accumulating artifacts), when you need to add transparency in an editor, or when maximum quality preservation justifies the larger file size.

HEIC to PNG FAQ

Quick answers about compatibility, quality, metadata handling, and the most common reasons to convert HEIC files to PNG.

How do I convert HEIC to PNG?

Upload your HEIC image to iFormat and click Convert — it's decoded and re-encoded to PNG in seconds. It's free, adds no watermark, and needs no account. Batch upload is supported, and results download individually or as a ZIP.

What is HEIC?

HEIC is Apple's efficient HEIF format, typically used for iPhone photos at small file sizes. Converting it to PNG makes the file easier to open, share, or upload where HEIC is not supported.

HEIC vs PNG — which format should I use?

HEIC is Apple's efficient HEIF format best for iPhone photos at small file sizes. PNG is a lossless format with transparency support best for logos, screenshots, and graphics with sharp edges. Use PNG when a website, form, or app requires it, or when you need PNG's specific strengths like smaller file size, wider compatibility, or transparency support.

How do I open HEIC files?

On Windows: Photos, after installing the free HEIF Image Extensions from the Microsoft Store. On a Mac: Preview and Photos, natively. This is the classic iPhone problem. Windows cannot open HEIC out of the box, and the required extension is easy to miss because Windows does not always prompt for it.

When should I convert HEIC to PNG instead of JPG?

Choose PNG when you need lossless quality (no compression artifacts at all), when you plan to edit the image repeatedly without accumulating quality loss, or when the image has transparency that needs to be preserved — though iPhone photos rarely have transparency.

Why is the PNG so much larger than my iPhone HEIC photo?

HEIC uses the highly efficient HEVC codec — a 12 MP iPhone photo is typically 1–3 MB. PNG is lossless and stores every pixel exactly, resulting in files of 15–30 MB for the same photo. The size increase is the cost of lossless storage.
