Introduction
In our digital lives, animated images are frequently used on social media, websites, and in memes to engage users and spark interaction. GIF (Graphics Interchange Format) is undeniably one of the most popular animated image formats. However, as technology evolves, there are now many other formats that offer higher-quality animations and smaller file sizes, such as WebP, APNG, and HEIF. If you're looking to create smaller, higher-quality animated images, it’s time to explore these advanced formats.
Animated Image Formats
WebP: Efficient Animated Images for the Web
WebP is an image format developed by Google, using VP series video codecs and a more efficient frame prediction algorithm. This means it delivers better image quality with smaller file sizes compared to GIF, which relies on a palette-based approach. WebP also supports better compression rates and richer color depth, making it more suitable for modern websites and applications.

WebP animations are smoother, support more colors and transparency, and offer much better visual quality with less noticeable jagged edges. The file sizes are reduced by more than 20%, improving load times and reducing bandwidth usage. This makes WebP the ideal format for modern websites and applications.
APNG: High-Quality Animated Images with Transparency
APNG (Animated Portable Network Graphics) is an extension of the PNG format, designed specifically for high-quality, transparent animations. Unlike GIF, APNG supports 24-bit color depth and transparent backgrounds, providing much higher image quality. APNG uses lossless compression, preserving the full color information, which makes it ideal for animations that require a transparent background.

Although APNG files tend to be larger than GIFs (by over 66%), they provide significantly sharper image quality. APNG is ideal for designs that require transparent background animations, such as website icons, interface elements, and motion graphics. However, it’s important to consider compatibility—while mainstream browsers support APNG, desktop applications may need special software to display them.
HEIF/HEIC: The Future of Efficient Image Formats
HEIF (High-Efficiency Image Format) is an emerging image format that uses the H.265 codec for compression. It’s much more efficient than JPEG, and supports both static and dynamic images. HEIC (High-Efficiency Image Coding) is a subset of HEIF, designed specifically for image encoding and animated video storage. Compared to traditional formats like JPEG or GIF, HEIF files are significantly smaller while preserving more detail.

HEIF/HEIC reduces file sizes by over 1000% compared to GIF, thanks to more aggressive frame optimization algorithms. Images appear more saturated and the background is often set to black, improving visual appeal. This makes HEIC particularly useful for high-resolution mobile images, photo albums, or high-definition videos. However, mainstream browsers cannot open HEIF/HEIC animated images yet—Apple devices support these formats by default, but other devices require additional software.
Enhancing the Animated Image Experience
With improvements in network bandwidth and image processing technologies, we no longer need to rely solely on GIF for animated images. Formats like WebP, APNG, and HEIF offer more efficient and higher-quality alternatives. By selecting the right animated image format for specific use cases, you can significantly enhance user experience and site performance.
Here are a few use cases for enhancing your animated image experience:
- Video apps can use APNG to showcase exciting clips and attract more viewers.
- Website applications can utilize WebP animated images to save bandwidth and improve load speeds.
- Mac users can store favorite animated images in HEIC format to save storage space on their devices.
