PNG vs GIF: What's the Difference?

PNG and GIF are both lossless, but GIF is limited to 256 colours and only on/off transparency, while PNG supports millions of colours and smooth, partial transparency. GIF's one real advantage is animation; for any still image, PNG is sharper and usually a better choice.

What's the core difference between PNG and GIF?

Colour. GIF uses an indexed palette of at most 256 colours, while PNG stores up to 16.7 million (PNG-24) or more. On a flat two-colour logo the difference is invisible, but on anything with gradients or photographic colour, GIF has to dither and visibly bands, whereas PNG reproduces the image cleanly.

How does transparency differ?

GIF transparency is all-or-nothing: each pixel is either fully visible or fully invisible, which leaves hard, jagged edges — obvious when a graphic sits on a coloured background. PNG's alpha channel offers 256 levels of opacity, so edges stay smooth and anti-aliased and soft drop shadows blend cleanly onto any background.

Why is GIF still around?

One reason: animation. The thing standard PNG can't do is move, and that has kept GIF alive for memes and short loops. But GIF is a poor animation format by modern standards — animated WebP and short MP4/ WebM clips are smaller and far higher quality. GIF's remaining appeal is ubiquity and how easily it drops into chats and posts, not its technical merits.

When should you use each?

Use GIF only for a short, simple looping animation you need to paste anywhere. Use PNG for every still image — logos, icons, screenshots, and any graphic that needs more than 256 colours or smooth transparency. For a still, PNG is both better-looking and, on most graphics, comparable or smaller in size.

How do you convert between PNG and GIF?

To turn a GIF into a clean still image, convert GIF to PNG — you'll get the first frame with the full colour range and proper transparency. If you're weighing transparency options in general, see how PNG transparency works.

Frequently asked questions

Is PNG better than GIF?
For still images, almost always — PNG offers millions of colours and smooth transparency where GIF is capped at 256 colours with hard-edged transparency. GIF only wins when you need a simple animation.
Does PNG support animation?
Standard PNG does not. The APNG extension adds animation, but its support is narrower than GIF's, which is why GIF still dominates simple looping clips.
Why does my GIF look grainy or banded?
GIF's 256-colour limit forces dithering on detailed or gradient images, which shows as speckling and banding. PNG keeps the full colour range, so it stays clean.
Can I convert an animated GIF to PNG?
You can extract a single frame as a still PNG with better colour and cleaner transparency, but one PNG can't hold the whole animation.
