What Is APNG?
APNG — Animated Portable Network Graphics — is an extension of the PNG format that supports animation. It was proposed in 2004 as a direct response to GIF's well-known limitations: the 256-color-per-frame cap, binary (on/off) transparency, and the technical constraints introduced by the original LZW compression patent. APNG stores each animation frame as a standard PNG image, meaning each frame can contain up to 16 million colors and full 8-bit alpha channel transparency.
Unlike WebP or AVIF, APNG does not require a new rendering engine or codec library. Any browser that can display PNG can display APNG — which today means every major browser including Chrome, Firefox, Safari, and Edge. APNG files are backward compatible: a browser that does not support the animation extension will simply display the first frame as a static PNG image, rather than showing a broken file.
APNG has been quietly supported across all modern browsers since 2017, when Microsoft Edge added support, completing the cross-browser picture. It has since become the format of choice for sticker packs, emoji, and product animations where quality matters more than raw file size.
APNG vs GIF: Why APNG Wins on Quality
Color Depth
GIF is limited to 256 colors per frame — a constraint from 1987 that was acceptable for early computer graphics but is a significant limitation for photographs, illustrations with gradients, and modern UI elements. APNG stores full 24-bit RGB color (or 32-bit RGBA with transparency), giving each frame access to the same 16.7 million colors as a static PNG. The visual difference on gradient-heavy content is dramatic.
Transparency Quality
GIF supports only binary transparency — each pixel is either fully transparent or fully opaque, with no partial transparency. This forces hard, jagged edges when placing an animated element on a colored or gradient background. APNG supports full 8-bit alpha per pixel, meaning edges can be anti-aliased and objects can have soft shadows, glows, and smooth fades that look correct on any background color.
Compression Efficiency
APNG uses DEFLATE compression (the same algorithm as PNG and ZIP), which typically produces smaller files than GIF's LZW compression for images with large areas of uniform color. For photographic or complex content with many colors, the larger bit depth can make APNG files larger than GIF. For illustrations, icons, and UI animations with flat colors and sharp edges, APNG files are often 20–40% smaller than equivalent GIFs.
When to Use APNG Over GIF
APNG is the right choice when visual quality is the priority and broad platform compatibility is already satisfied. The key use cases where APNG clearly outperforms GIF:
- →
Animated stickers and emoji. Custom Discord stickers, Telegram animated stickers, and app-specific emoji require smooth edges and full color. APNG's alpha transparency means sticker edges anti-alias correctly against any background — something GIF's binary transparency cannot achieve.
- →
UI and product animations. When animating a UI element on a website — a loading spinner, an animated logo, a button hover state — APNG maintains the same visual quality as the static PNG assets in the rest of the design. GIF's color reduction visibly degrades smooth gradients and renders brand colors incorrectly.
- →
Artistic and illustrated animation. Digital illustration and pixel art often contain subtle shading and anti-aliased edges that GIF's 256-color palette cannot faithfully reproduce. APNG preserves every tone and color in the original source artwork.
- →
Transparent overlays. When an animation needs to play over a dynamic or user-chosen background — a chat app with custom themes, a dark/light mode toggle — only APNG can produce the smooth, professionally finished result that GIF cannot due to its binary transparency limitation.
Browser and Platform Support
As of 2024, APNG is supported in all major browsers without any flags or extensions:
Chrome
Full support since v59 (2017)
Firefox
Full support since v3 (2007)
Safari
Full support since v8 (2014)
Edge
Full support since v12 (2015)
iOS Safari
Full support since iOS 8
Chrome Android
Full support since v59
The only notable platforms where APNG playback is not guaranteed are older email clients and some messaging apps that use a custom rendering engine. For email, GIF still has a slight compatibility edge. For all web and modern app contexts, APNG is a safe and superior choice.

Open the EditorFrequently Asked Questions
Is APNG supported in all browsers?
Yes. All major modern browsers — Chrome, Firefox, Safari, Edge, and their mobile variants — support APNG. The only notable exception is Internet Explorer, which reached end-of-life in 2022. For any web-facing use case in 2024 and beyond, APNG browser support is effectively universal.
Will my APNG be smaller than the original GIF?
It depends on the content. For images with large flat-color areas, solid backgrounds, and sharp edges (icons, logos, illustrations), APNG files are typically 10–40% smaller than equivalent GIFs thanks to DEFLATE's superior compression of uniform regions. For complex photographic content or animations with noisy, detailed frames, APNG files can be larger because they store full 24-bit color per pixel.
Does APNG support full-color images without banding?
Yes, that is one of the primary advantages of APNG over GIF. APNG stores 24-bit RGB color (or 32-bit RGBA with transparency), giving each frame access to 16.7 million colors. GIF is limited to 256 colors per frame. For any content with smooth gradients, photographic detail, or precise brand colors, APNG preserves full fidelity while GIF introduces visible color banding.
Can I use APNG in emails?
APNG in email is a mixed picture. Gmail, Apple Mail, and Thunderbird display APNG animations correctly. Outlook (Windows desktop versions) does not support APNG and will fall back to showing the first frame as a static image. For maximum email compatibility, GIF remains the safer choice for animated content in HTML emails.
What is the difference between APNG and WebP?
Both are modern replacements for GIF with better quality and compression. WebP (developed by Google) offers superior compression ratios and is ideal for photographs and complex imagery. APNG (an extension of PNG) is preferred for graphics, illustrations, icons, and content with transparency because it integrates seamlessly with existing PNG workflows and has identical transparency handling. APNG is also more widely supported in design tools than animated WebP.
