HEIC and PNG solve different problems. HEIC is built to store high-quality photos in as little space as possible, which is perfect for a phone’s camera roll. PNG is built for perfect, lossless fidelity and universal support, which is perfect for sharing, editing, and the web.
Side-by-side comparison
| Attribute | HEIC / HEIF | PNG |
|---|---|---|
| Compression | Lossy (HEVC), very efficient | Lossless, preserves every pixel |
| Typical file size | Small (~1–3 MB per photo) | Larger (often 2–5× the HEIC) |
| Transparency (alpha) | Supported | Supported |
| Browser compatibility | Limited (mainly Safari/Apple) | Universal (every browser) |
| Editing & software support | Growing, but still spotty | Supported almost everywhere |
| Best for | Saving space on Apple devices | Sharing, web, editing, archiving |
| Animation / sequences | Supported (Live Photos, bursts) | Single still image only |
Why is a PNG bigger than the HEIC?
HEIC uses efficient lossy compression, discarding data your eye is unlikely to notice. PNG uses lossless compression — it records every pixel exactly. As a result, a converted PNG can be several times larger than the original HEIC. That’s the price of PNG’s perfect fidelity and its ability to open anywhere.
When should you convert HEIC to PNG?
- You need to open or edit the image on software that doesn’t read HEIC.
- You’re uploading to a website or app that only accepts common formats.
- You want a lossless copy for archiving or further editing.
- You need transparency preserved in a widely supported format.
If small file size matters more than universal support (for example, keeping photos on your phone), HEIC is the better choice. Otherwise, converting to PNG with our free converter is quick and private.
What is HEIC?
HEIC (High Efficiency Image Container) is Apple’s implementation of the HEIF standard. Inside the container, the image is compressed with the HEVC (H.265) codec — the same efficient compression used for 4K video — which is why a HEIC photo is roughly half the size of an equivalent JPEG. Beyond raw efficiency, the format supports higher bit-depth color, transparency, and multi-image sequences such as Live Photos and bursts. Apple made it the default camera format in iOS 11, which is why almost every recent iPhone photo is a .heic file.
What is PNG?
PNG (Portable Network Graphics) is a decades-old, universally supported format built around lossless compression. Where HEIC and JPEG throw away data to shrink a file, PNG records every pixel exactly. It also has first-class support for transparency. That combination makes PNG the go-to format for screenshots, logos, graphics, editing, and anywhere an image needs to open reliably — every browser, editor, and operating system reads PNG without any add-on.
Does converting HEIC to PNG lose quality?
No visible quality is lost. When a HEIC file is decoded, you get the exact pixels the format stored; re-encoding those pixels as PNG is lossless, so nothing further is discarded. The one thing that changes dramatically is file size — the PNG will be noticeably larger, because it isn’t using HEIC’s space-saving compression. If you’d prefer a smaller result, the converter offers an optional “reduce file size” mode that produces a compact PNG with no visible difference for most photos.
HEIC to PNG or HEIC to JPG?
PNG and JPG solve different problems. PNG is lossless and keeps transparency, which makes it ideal for editing, archiving, graphics, and anything with sharp edges or text. JPG is lossy but produces much smaller files, which is often better for sharing ordinary photographs where a tiny quality loss doesn’t matter. This tool outputs PNG; for a full breakdown of the alternative, see HEIC vs JPG.
Frequently asked questions
Is PNG better than HEIC?
Neither is universally “better” — they’re optimized for different goals. HEIC wins on file size and is great for storing photos on a phone. PNG wins on compatibility and lossless fidelity, which is why converting is worth it when you need to open, edit, or upload the image somewhere HEIC isn’t supported.
Why is my converted PNG so much bigger?
Because PNG is lossless. HEIC uses efficient lossy compression to keep files tiny, while PNG stores every pixel exactly. A converted PNG being several times larger than the original HEIC is expected and normal.
How do I convert HEIC to PNG?
Open the converter, add your HEIC files, and download the PNGs — it runs entirely in your browser with nothing uploaded. Step-by-step instructions are on our how to convert HEIC to PNG page.
