Frequently Asked Questions

Will resizing reduce GIF quality?

Our tool uses the Lanczos algorithm which produces the best quality when scaling. Upscaling may show some softening, but downscaling generally looks great.

What sizes work best for social media?

Discord emoji: 128px, Discord sticker: 320px, Twitter: 480px, Tumblr: 540px. Use our presets for optimal sizes on each platform.

Does resizing change the file size?

Yes! Smaller dimensions usually mean smaller files. Reducing a GIF from 500px to 250px width can cut file size by 50-75%.

Can I resize without losing aspect ratio?

Yes, use the "Lock aspect ratio" option to maintain proportions. Only width or height needs to be set - the other adjusts automatically.
