Animated GIFs are the universal language of social media, Slack messages, GitHub pull requests, and email newsletters. However, uploading videos to online GIF converters often means waiting in long server queues and getting watermarked results.

ILoveImages' GIF Maker processes video clips and image sequences entirely in your browser using fast WebAssembly canvas rendering, giving you smooth frame rates and sharp color palettes with zero server uploads.
