Image Format Comparison

PNG vs GIF: Which Format Should You Use?

PNG replaced GIF for static images in the early 2000s and is strictly better in every way for that use case. GIF persists only because it's the universal animated image format — every email client, Slack, GitHub, and messaging platform that blocks video still shows animated GIFs. For everything static, use PNG. For everything animated, use GIF (or animated WebP where supported).

Quick Verdict

Use PNG when…

Use PNG for static images — better colour support, smoother transparency, smaller files for most graphics, and universal lossless quality.

Use GIF when…

Use GIF only for animated images that must work in email clients, Slack, or older platforms that don't support animated WebP or video.

PNG vs GIF: Feature Comparison

Feature	PNG	GIF
Max colours	16.7 million (24-bit) or 16-bit per channel	256 colours maximum (8-bit palette)
Animation	No (APNG extension exists but limited support)	Yes — native animated GIF support everywhere
Transparency	Full alpha channel — any level of transparency	Binary only — pixel is fully transparent or fully opaque
Compression	Lossless DEFLATE — better than GIF for most images	Lossless LZW — good for flat colour images
Colour gradients	Perfect — full colour depth	Poor — 256 colours causes visible banding
Logos with transparency	Best choice — full alpha, perfect edges	Acceptable only for flat-colour logos

Frequently asked questions

Is PNG better than GIF for icons and logos?

Yes, always. PNG supports millions of colours (vs. GIF's 256), has full alpha transparency (vs. GIF's binary on/off), and produces smaller files for most logos and icons. GIF logos have colour banding and poor anti-aliasing due to the 256-colour limit. The only scenario where GIF beats PNG for static images is extremely simple flat-colour graphics where GIF's LZW compression happens to outperform PNG — which is rare.

Can PNG be animated?

Technically yes — APNG (Animated PNG) is a PNG extension that supports multiple frames for animation. APNG is supported in Chrome, Firefox, Safari, and Edge, and produces much smaller files than GIF with full colour support. However, APNG is not as universally supported as GIF in email clients and older apps. Animated WebP is another alternative with better compression than both.
