GIF Editor

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.

Runs on FFmpegJSZip

100% Local Browser Native

How to Use the GIF Editor

1. Upload one GIF

Single animated GIF; header parses width, height, frame count, KB, and duration from the binary.

2. Set resize, speed, reverse, palette

Lanczos resize with aspect lock, setpts speed, reverse filter, palettegen/paletteuse color optimize — combined into one FFmpeg filter chain.

3. Process or extract frames

Process renders output.gif; Extract Frames saves every frame as PNG plus a <name>_frames.zip.

GIF Resizer

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.

Open Tool

GIF Compressor

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.

Open Tool

GIF to APNG

Upgrade one GIF to APNG via FFmpeg apng codec at locked 10fps and source dimensions (Lanczos) — 24-bit color plus 8-bit alpha, no size/quality settings. Result panel shows GIF vs APNG KB with ±% change; saves as <name>.png. Modernize sticker packs — local FFmpeg work, unlimited saves.

Frequently Asked Questions

What can I edit?

Resize, playback speed, reverse, palette optimization, and PNG frame extraction — that is the complete op list. No crop, text overlays, or clip trimming exist.

Does it stay animated?

Yes — processing forces loop forever (-loop 0, -ignore_loop 0) and edits preserve animation; exports play everywhere GIFs play.

Quality vs size?

Trim dimensions via Lanczos resize and cap palette max_colors first — the two levers that shrink GIFs most. Palette mode uses stats diff/single with bayer dither scale 5.

Is my work uploaded anywhere when using GIF Editor?

No — editing runs locally in your browser via FFmpeg WASM; unlimited saves on local tools.
