Will the resized file still be animated?

No. The editor here resizes the GIF as a still image — it works on a single frame and saves to JPG, PNG, WebP, TIFF, or BMP, none of which carry the animation. If you need the loop preserved, resize with Compress GIF: set its Image resolution to a percentage or preset and every frame is rescaled together, keeping the timing, loop count, and transparency.

My resized GIF came out bigger than the original. What happened?

That happens on whole-animation rescales when the source was heavily optimised with delta frames (only the changing pixels stored each frame) and the resize step expanded every frame back to a full canvas. The fix lives in Compress GIF, where the rescale runs: cut the colour palette, lower the image quality, or set a Max file size cap there and the optimisation is re-introduced after the resize.

What dimensions should I use for a Slack custom emoji?

128×128 pixels, square, with up to 50 frames. Stay under 128 KB total — Slack rejects anything 1 byte over. For a static emoji, enter 128 into W and H here and download as PNG. For an animated emoji, do the whole job in Compress GIF — 50% resolution plus a 64-colour palette fits moderately complex animations, and a frame-drop pass covers the rest.

What about Discord animated emoji?

128×128, square, ≤256 KB. Animated server emoji slots require at least Server Boost level 1. Free Discord uploads of regular GIF files now cap at 10 MB (lowered from 25 MB in September 2024); for inline GIFs to auto-play in chat the file should be under ~256 KB or it loads as a static thumbnail.

How much smaller does halving the dimensions make a GIF?

Roughly 60–75% smaller. Cutting width and height in half drops pixel count to a quarter, but GIF's LZW compression doesn't shrink linearly with pixels — neighbouring-pixel patterns compress better at smaller sizes, and the saving compounds across every frame. A 1080p 8 MB loop usually lands around 2–2.5 MB at 540p with the same palette.

Should I resize the GIF or convert it to MP4 / WebP / WebM?

If the destination is a webpage or modern chat client, GIF to MP4 or GIF to WebP typically gives 5–20× smaller files at higher quality. Stick with GIF only when the target needs the literal .gif extension — Slack/Discord emoji slots, classic forum embeds, or platforms that strip tags. For the reverse direction (recording → GIF), MP4 to GIF and WebM to GIF are the usual entry points.

Why does my emoji look pixellated after resize?

GIF only carries 256 unique colours per frame. When you scale a photographic source down to 128×128, the resampler picks new pixel values that don't exist in the original palette, and re-quantising back to 256 colours introduces banding. Reducing the palette to 32 or 64 colours in Compress GIF actually helps — the encoder gets a chance to choose a palette that matches your shrunk image rather than carrying over the original's 256 entries.

Can I resize and crop in the same pass?

Yes — they're two tabs of the same editor. Switch to the Crop tab, drag the crop box (or pick a preset like 1:1), then come back to Resize and scale the cropped result. Crop before you resize: cropping first means you're not downscaling pixels you're going to discard anyway. There's also a standalone Crop GIF page that opens on the Crop tab directly.

Do I need an account, and is there a watermark?

No account, no watermark, and no payment gate — the editor is free to use. Nothing is published or shared: there's no public link generated, and the only output is the file you download.
