GIF Maker

Step 1 / 4 GIF maker

Add at least two frames.

Animated GIFs are still one of the easiest ways to add a reaction to Slack, a quick tutorial to a README or a product micro-interaction to a landing page. This GIF maker stitches PNG/JPG frames or a trimmed MP4 into a looping 256-colour GIF, then lets you tune the frame rate, canvas size and loop count before download.

How to build a GIF

  1. 1

    Add frames

    Upload PNG/JPG images in order, or add a short MP4 that can be sampled into frames.

  2. 2

    Set the frame rate

    Use 8–12 fps for UI demos and 15–24 fps when you want smoother, video-like motion.

  3. 3

    Choose size and looping

    Resize the canvas and decide whether the GIF should loop forever or stop after a fixed number of plays.

  4. 4

    Export and download

    The tool encodes the animation with palette optimisation and returns one .gif file.

GIF format limits

Attribute Limit or behaviour
Colour depth 256 colours per frame (8-bit palette)
Alpha 1-bit transparency: each pixel is either fully transparent or fully opaque
Frame delay Stored in 10 ms steps, so a “60 fps GIF” effectively tops out near 50 fps
Compression LZW compression, strongest on flat graphics and UI captures
File size No formal limit, but many browsers and chat apps struggle beyond about 10 MB

Tips to keep the file small

  • Trim to the essential motion. Most reaction GIFs work best at 1–3 seconds.
  • Downscale before export. A 480 px wide GIF is usually enough for Slack, X/Twitter, Notion and documentation pages.
  • Drop frames before dropping colours. Halving the fps often halves the file size; reducing the palette from 256 to 64 colours can visibly damage gradients.
  • Prefer clean backgrounds. Screen captures and flat UI animations compress far better than noisy video footage.

When MP4 or WebM is the better format

If the destination supports short autoplaying video, such as X/Twitter, Discord or a modern web page, MP4 (H.264) or WebM (VP9) can be 5–10 times smaller than a comparable GIF at the same visual quality. GIF remains useful for chat, email, issue trackers and older documentation systems that treat it as an image.

Frequently Asked Questions

GIF is limited to 256 colours and uses a palette-based image format. Smooth gradients can turn into dithering noise, and skin tones often show banding. For a cleaner result, reduce motion detail, crop the scene or use MP4/WebM when the destination supports it.

Yes, but GIF only supports 1-bit transparency. A pixel is either fully transparent or fully opaque, so soft anti-aliased edges can look jagged against different backgrounds. Use APNG or WebP when you need smooth alpha.

12–15 fps is a practical default. It keeps motion readable without producing huge files, and platforms that convert GIFs to video still handle that range well.

Encoding runs in the page and the finished GIF is returned for download. The source frames are not retained after export.
