Convert GIF to WebP on Mac: 3 Methods

Convert GIF to WebP on Mac with GetCompress, FFmpeg, or QuickTime when the source is still video. Smaller animated assets for the web.

By Petr Samokhin

Your landing page hero animation is a multi-megabyte GIF. The same loop as animated WebP is often much smaller with smoother gradients. Modern browsers load animated WebP well. Keep a GIF or MP4 fallback when a CMS or email client still requires it.

Why animated WebP instead of GIF

GIF caps at 256 colors per frame. Animated WebP supports lossy and lossless modes and typically produces smaller files at similar visual quality.

Browser supportUniversalWide on modern browsers

Use animated WebP when page weight hurts. Keep GIF when a third-party tool accepts only GIF. For UI demos, MP4 is often better than either. See compress GIFs on Mac when you must stay in GIF.

Method 1: GetCompress

Best for: Preview, trim, width presets, and batch export without maintaining FFmpeg recipes per project.

GetCompress main window with a GIF queued and GIF settings open, including quality and format options
  1. Drop an existing GIF, or a MOV/MP4 source, into GetCompress .
  2. Trim idle frames in the preview.
  3. Choose WebP output, set width (for example 640 or 800 px) and quality.
  4. Export; keep the original GIF or video master untouched.

Processing stays on your Mac. Save a preset such as “marketing WebP 640 medium” so you can reuse it next time.

Method 2: Convert GIF to WebP with FFmpeg

Best for: Scripts and exact libwebp flags.

Install FFmpeg with Homebrew if needed:

brew install ffmpeg

Lossy animated WebP:

ffmpeg -i loop.gif -vcodec libwebp -filter:v "fps=12,scale=640:-1" -lossless 0 -compression_level 6 -q:v 80 -loop 0 loop.webp

Lossless (larger file, flat colors):

ffmpeg -i icon-loop.gif -vcodec libwebp -lossless 1 -loop 0 icon-loop.webp

Batch every GIF in a folder:

mkdir webp-out
for f in *.gif; do
 ffmpeg -i "$f" -vcodec libwebp -filter:v "fps=12,scale=640:-1" -lossless 0 -q:v 80 -loop 0 "webp-out/${f%.gif}.webp"
done
FlagSmaller fileBetter quality
fps8 to 1012 to 15
scale width480 to 640800 to 960
-q:v (lossy)70 to 7580 to 85

Limitation: You maintain the commands yourself. Re-encoding GIF to WebP and back causes generation loss; keep the MP4 or MOV master when you have it.

Method 3: Start from video in QuickTime

Best for: When the source is still a screen recording, not a finished GIF.

  1. Open the clip in QuickTime Player.
  2. Edit → Trim (⌘T).
  3. Export MP4 when the destination allows video, or convert to GIF/WebP only if required.

See video to GIF on Mac when GIF is required.

Limitation: QuickTime does not export animated WebP directly.

When FFmpeg alone is enough

FFmpeg is enough for a one-off convert when you already know the flags.

GetCompress also helps when design sends a folder of oversized GIF files often, when you want trim and preview before deploy, and when processing must stay local. Prefer MP4 for motion docs when quality stays poor at a small animated size. For Windows, see GIF to WebP on Windows .
