Why Use the Emoji Resizer
Meet Platform Size Requirements
Every platform has specific emoji size requirements. Discord and Slack recommend 128x128px, Twitch requires 28px/56px/112px for emote tiers, Teams works best at 256px. The resizer outputs emojis at exactly the right dimensions so they upload without errors.
Consistent Sizing for Emoji Sets
When building an emoji pack or migrating between platforms, every image needs to be the same size. Use the resizer to standardize an entire set to one dimension. Every result will be exactly the same pixel dimensions.
Export for Multiple Platforms at Once
Running a community across Discord, Slack, and Twitch? Resize the same emoji to each platform's required dimensions. One source image, multiple platform-ready outputs.
Emoji Resizer FAQs
What size should my emoji be for Discord?+
Discord recommends 128x128px. Max file size is 256KB for both static and animated emojis. Use 128px in the resizer for optimal Discord results.
What sizes does Twitch require for emotes?+
Twitch requires three sizes: 28x28px (1x), 56x56px (2x), and 112x112px (3x). Upload the 112px version and Twitch generates the smaller sizes, or create all three here for full control.
Does resizing affect animated emoji quality?+
The resizer preserves animation frames and timing when scaling. Sizing down from a larger source produces sharper results. For animated GIFs, smaller pixel dimensions also mean smaller file sizes, helping meet upload limits.
Can I resize to a custom dimension?+
The resizer offers preset sizes (28px through 512px) covering all major platforms. These presets are optimized for the platforms that use them.
What is the ideal emoji size for Slack?+
Slack recommends 128x128px. Max file size is 128KB (free) or 1MB (paid plans). Square images work best since Slack displays emojis as squares.
Is the emoji resizer free?+
Completely free. No signup, no watermarks, instant downloads. Supports all major formats and platform sizes.
