Compress GIF
Reduce a GIF's dimensions or frame rate to lower its file size. The best settings depend on the animation, so compare the preview and measured output before downloading.

Why GIF Files Get So Large
GIF animation uses indexed color, with a palette of up to 256 entries per frame, and LZW compression. Unlike modern video codecs, it generally cannot exploit motion with the same efficiency. Size is affected by pixel dimensions, frame count, and content: detailed, noisy scenes often need more data than simple graphics.
In practice, duration, frame dimensions, frame rate, and image detail all matter. Shortening a clip reduces the number of frames; cropping removes pixels that do not matter; reducing width or frame rate lowers visual information. The exact size change depends on the source and encoder.
The editor lets you set start and end times, output width, frame rate, and a target size. A target size is a best-effort search through lower width/frame-rate combinations, not a guarantee that a limit can be met without visible tradeoffs. Lanczos resampling is used when scaling.
How Our GIF Compressor Works
Our tool runs FFmpeg compiled to WebAssembly (WASM) entirely inside your browser tab. Nothing is sent to a server. When you click "Compress GIF", FFmpeg applies the following pipeline to your file:
Frame rate
Lower frame rates can reduce frame count and size, but fast movement and cursor motion may look less smooth. Try a modest reduction first, then compare the animation at normal playback speed.
Output dimensions
Smaller frames contain fewer pixels, but text and fine edges also become harder to read. Choose a width for the intended display context rather than relying on a universal best width. The editor keeps the aspect ratio when scaling.
Lanczos Resampling
Lanczos resampling is used for scaling, but it cannot restore detail lost by shrinking. GIF palette conversion can still affect gradients and photographic content. Keep the original if you may need a larger version later.
Tips for Getting the Smallest File
- 1
Trim before compressing. The shorter the source clip, the smaller the output. Even one extra second at 10 fps adds 10 frames to encode. Clip tightly to just the action you want to show.
- 2
Crop to the interesting region. If only part of the frame is relevant, crop the rest before compressing. A 200 × 200 GIF has four times fewer pixels than a 400 × 400 GIF — the compression dividend is immediate.
- 3
Avoid repeated lossy conversions. Work from the original and adjust duration, crop, width, and frame rate in one pass. Re-encoding an already reduced animation can compound visual changes.
- 4
Prefer static or low-motion content. GIFs of text changing, UI transitions, or simple geometric animations compress far better than camera pans or natural video. High-motion content with unpredictable color changes produces poor LZW compression regardless of the settings you use.
Choosing a target size
Upload limits and animation behavior change between services, account tiers, and posting workflows, so a fixed table can quickly become misleading. Check the current limit where you plan to share the file. The editor's target-size option (1, 2, 5, 8, or 10 MB) searches progressively smaller width and frame-rate settings; it is a best effort, not a promise. Confirm the actual size shown after conversion, then test the file in its destination.
If you cannot reach the limit without making the animation difficult to watch, shorten the clip, crop out irrelevant space, or choose MP4/WebM when the destination accepts video. Video is usually a better fit for longer or photographic motion; GIF is useful when an inline looping image is specifically needed.

Open the EditorFrequently Asked Questions
What is a good target file size for a compressed GIF?
There is no one target that guarantees acceptance: platform limits and playback behavior vary by account, app, and upload path. Check the current destination guidance, use a target-size preset as a starting point, and verify the actual exported size.
Does compressing a GIF reduce visual quality?
Compression can change the appearance. Lower frame rates can make motion less smooth, smaller dimensions reduce detail, and palette conversion can cause banding or dithering. Compare the preview and downloaded file at its intended display size.
What frame rate should I use for screen recordings vs. animations?
There is no best rate for every clip. Use a lower rate for slow screen demonstrations when size matters; retain more frames for fast motion. Preview at normal speed and check cursor movement and text for stutter.
Can I compress a GIF multiple times?
You can, but repeated encoding may compound visual changes. Start from the original and combine trimming, cropping, width, and frame-rate adjustments in one pass where possible.
Why is my GIF still large after compression?
Very high-motion content — a camera panning across a busy scene, natural video, or fast-moving particles — is inherently difficult to compress with GIF because every pixel changes between frames. Try shortening the clip, cropping to a smaller region of interest, or lowering the frame rate below 10 fps. If the file is still too large, consider keeping it as an MP4 or WebM for platforms that support video.
