Resize one animated GIF to exact dimensions via FFmpeg Lanczos (default), Bilinear, or Nearest — width presets 100/150/200/320/480/640px or custom, height auto-follows with aspect lock ON (unlock to stretch). W/H prefill from the source; saves as <name>-resized.gif with animation intact.
Edit animated GIFs in your browser with FFmpeg WASM — resize (Lanczos, aspect lock), speed (setpts), reverse, palette optimize (max_colors with bayer dither), and PNG frame extraction to <name>_frames.zip. No crop, text, or trim tools. Header shows WxH, frame count, KB, and seconds.
Compress one animated GIF with FFmpeg: colors slider 2–256 (default 128), Floyd or no dithering, loss tolerance 0–100 (above 50 flips lossless to lossy), and optional duplicate-frame removal (mpdecimate, off by default). Output fps locks to 10; result shows KB and -% and saves as <name>-compressed.gif.
Reduces MP4, MOV, and WebM video file sizes with a configurable CRF 20–40 slider (default 28, libx264 fast preset), plus a GIF mode with color-palette control. Videos never leave your device — compression runs locally in your browser with FFmpeg WASM.
Compress multiple videos with one shared CRF setting (18 high quality, 23 default, 28 smaller, 35 maximum) encoded libx264 medium preset with 128k AAC audio. Studios batch 20 daily uploads at CRF 28 — local FFmpeg WASM, 2 free batches a day.
APNG (Animated PNG) is an extension of PNG that supports animation. It offers better quality than GIF with full alpha transparency and 24-bit color, but has limited browser support.
GIF is universally supported by all browsers, messaging apps, and platforms. Converting APNG to GIF ensures your animation plays everywhere.
GIF is limited to 256 colors and 1-bit transparency. APNG's full-color, full-transparency animation will lose quality. The converter optimizes the palette to minimize visible loss.
Yes. Frame timing from the APNG source is preserved in the GIF output. The animation plays at the same speed as the original.
Yes. All conversion runs in your browser using FFmpeg. No files are uploaded.
