Emote Resizer is a browser-based tool that prepares emote, badge, and sticker artwork for multiple platforms in a single step. Users upload or paste an image and receive the exact file specifications required by Twitch, Discord, 7TV, BetterTTV, FFZ, and Slack. Supported input formats include PNG, JPEG, WebP, and GIF. The tool runs its image processing locally in the browser, so source images are not uploaded to any server. Platform-specific presets cover Twitch emotes at 112, 56, and 28 pixels, Twitch sub badges at 72, 36, and 18 pixels, Discord emoji at 128 pixels, Discord stickers at 320 pixels, the 7TV/BetterTTV/FFZ ladder at 128, 64, and 32 pixels, and Slack emoji at 128 pixels. A custom size option accepts any square dimension from 8 to 1024 pixels. For each output, the tool displays the generated file size and flags any files that exceed a platform limit, such as the 256KB Discord emoji cap or the 512KB GIF limit for Twitch emotes. Batch processing is enabled by default, allowing multiple images to be dropped at once with each output resized to the full set of selected specifications. Non-square artwork is centered and padded rather than stretched. The workflow also includes a clipboard paste option, a Discord Sticker Maker for cropping and outlining, and a tool for creating emote artwork from scratch. Dedicated reference pages provide the full notes for each platform specification.
