GIF to APNG converter online free — convert animated GIF to animated PNG

Free GIF to APNG converter: convert animated GIF to animated PNG online. Preserve frames and timing, full color RGBA output, lossless quality. No upload, works in your browser.

What is a GIF to APNG Converter?

A GIF to APNG converter transforms animated GIF files into Animated Portable Network Graphics (APNG) while preserving every frame and all timing information. Unlike GIF which is limited to 256 colors per frame and binary transparency, APNG supports full 24-bit color and 8-bit alpha channels — making it ideal for animations with gradients, semi-transparency, and rich color palettes. This free online GIF to APNG converter runs entirely in your browser: upload an animated GIF, the tool decodes every frame with gifuct-js, assembles the pixel data into a multi-frame APNG using UPNG.js with lossless encoding, and delivers a .png file that plays as an animation in all modern browsers, Discord, Telegram, and most chat platforms. Perfect for game assets, UI animations, screenshots, and any scenario where GIF's color limitations are a problem.

GIF to APNG Converter Features

Convert animated GIFs to animated PNGs with full quality.

  • Lossless Conversion

    Frame-for-frame perfect conversion. All pixel data from your GIF is preserved in the APNG output with no quality loss.

  • Full RGBA Output

    APNG supports full 24-bit color and 8-bit alpha. GIF's limited palette is carried into the richer APNG container without banding.

  • Timing Preserved

    Every frame delay from the original GIF is mapped to the corresponding APNG frame timing. The animation speed is identical.

  • Client-Side Processing

    GIF parsing and APNG encoding happen entirely in your browser. No file uploads, no accounts, no limits.

How to Convert GIF to APNG

Three simple steps to convert your animated GIF to APNG.

  1. 1. Upload Your GIF

    Drag and drop an animated GIF into the upload area, or click to browse from your device.

  2. 2. Convert

    Click Convert to APNG to decode every GIF frame and re-encode as a lossless animated PNG.

  3. 3. Preview & Download

    Review the converted APNG in the preview area and click Download to save it as a .png file.

Tips for GIF to APNG Conversion

Best practices for getting the best APNG results.
  • 01

    APNG vs GIF File Size

    APNG is typically larger than GIF for the same content because it stores full RGBA data instead of a 256-color palette. Use APNG when quality matters more than file size.

  • 02

    Check Platform Support

    All modern browsers support APNG natively, but some older apps and sites may only accept GIF. Check compatibility before switching formats.

  • 03

    Long Animations May Be Large

    Multi-frame GIFs with many frames produce large APNG files since each frame stores full RGBA data. Consider shortening very long GIFs before converting.

  • 04

    Preview Before Downloading

    Review the converted APNG in the preview area to verify frame timing and visual quality before saving.

Perfect for These Uses

Common scenarios for converting GIF to APNG.

  1. Better Quality GIFs: If a platform supports APNG, use it instead of GIF for sharper colors and smoother gradients with the same file size.

  2. Game Assets & UI: APNG with full alpha transparency is ideal for game sprites, UI animations, and design mockups where GIF banding is unacceptable.

Technical Details

How the GIF to APNG converter works under the hood.
GIF Decoding
The tool parses raw GIF binary data with gifuct-js, extracting every frame's pixel data, dimensions, delay timing, and applying disposal methods.
APNG Encoding
UPNG.js encodes the frame sequence as PNG with acTL (Animation Control) and fcTL (Frame Control) chunks for timing metadata and animation playback.
Lossless Quality
Encoding uses cnum=0 (lossless) so all original pixel data is preserved exactly as decoded from the GIF frames.
Client-Side Processing
All parsing, decoding, and encoding runs entirely in JavaScript in your browser. No server processing.
Supported Input
Animated GIF files up to 15 MB. Supports both GIF87a and GIF89a formats. Maximum frame edge is 8192 pixels.
Output Format
Output is a PNG file containing an APNG animation with acTL and fcTL chunks. Plays in all modern browsers, Discord, Telegram, and most image viewers.
