Animated PNG (APNG) Editor & Maker

APNG (Animated PNG) brings full-color animation to the PNG format: 24-bit color with 8-bit alpha transparency, compared to GIF's 256 colors and binary transparency. The result is smoother gradients, cleaner edges, and no color banding. FastEdit lets you create, edit, and convert APNG files directly in your browser.

APNG is the format of choice when you need animation with high color fidelity and smooth transparency, think animated UI mockups, game sprites, or branding assets where GIF's color limitations are unacceptable.

Codec DEFLATE (same as PNG, extended with animation chunks)
Color Depth 24-bit RGB + 8-bit alpha (16.7M colors + full transparency)
Animation Support Yes, multi-frame with per-frame delay and disposal methods
Transparency Full 8-bit alpha channel (smooth semi-transparency)

What it handles

  • Create APNG animations from video clips (MP4, WebM) or other animated formats (GIF, WebP)
  • Timeline editing for trimming, reordering, and adjusting per-frame timing in existing APNG files
  • Full 24-bit color with 8-bit alpha, no 256-color palette limitation like GIF
  • Convert APNG to GIF, WebP, or MP4 for platforms that don't support animated PNG
  • Speed control, reverse, and ping-pong loop modes for creative animation effects
  • Frame deduplication to reduce APNG file size by removing visually redundant frames

Where it fits

  • Creating animated UI component previews for design handoff where color accuracy and transparency matter
  • Making animated stickers and emoji with smooth semi-transparent edges for messaging platforms
  • Building animated game sprites that need precise per-pixel alpha blending, not binary transparency
  • Replacing GIF animations on websites where color banding or fringing is unacceptable
  • Producing animated explainer graphics for technical documentation with crisp text overlays
