TinyGIF is a set of free browser GIF tools: a compressor with presets at 256 KB, 512 KB, 1 MB and 10 MB, Discord emoji, banner and sticker tools, Twitch and Kick emote resizers, video and MP4 to GIF, GIF to APNG and WebP to GIF. The site says your files stay on your device. No signup or watermark.

I kept hitting file-size caps on Discord, Twitch and Kick emotes and banners, and most GIF compressors force you to upload your files to a server. TinyGIF is free, private and needs no signup or watermark.
