TwitchHow to Resize Emojis
Upload Your Emoji
Upload the emoji or image you need to resize. Accepts JPG, PNG, and GIF formats. Works with any starting size — from tiny 16px icons to large 1024px images.
Select Your Exact Size
Choose a preset: 28px and 56px for Twitch chat, 128px for Discord, Slack and Teams, 256px for retina, or 512px for print.
Download Platform-Ready
Download your resized emoji at the exact pixel dimensions you selected. Optimized for file size and quality, meeting upload requirements for Discord, Slack, Twitch, and Teams.
Why Use the Emoji Resizer
Meet Platform Size Requirements
Each platform wants something different. Discord and Slack render at 128×128, Twitch needs 28, 56 and 112px for its emote tiers, and Teams caps out at 220×220 with a tight 50 KB budget, so 128px is the safe choice there.
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 wants square images at 128×128, under 128KB. Squares matter because Slack crops to one either way.
Is the emoji resizer free?+
Completely free. No signup, no watermarks, instant downloads. Supports all major formats and platform sizes.
Upload limits, platform by platform
The ceilings differ enough that a file which works on Discord can bounce off Teams. These are the numbers each platform publishes.
| Platform | Max size | Dimensions | Formats |
|---|---|---|---|
| Discord | 256 KiB | 128×128 | PNG, GIF |
| Slack | 128 KB | square, 128×128 recommended | PNG, JPG, GIF (up to 50 frames) |
| Twitch | 1 MB | 28×28, 56×56 and 112×112 | PNG, GIF (up to 60 frames) |
| Microsoft Teams | 50 KB | up to 220×220 | PNG, GIF |
- Discord: Animated emoji need a Nitro subscription or a boosted server.
- Slack: Transparent backgrounds render best against both themes.
- Twitch: Uploading each size by hand caps every file at 512 KB instead.
- Microsoft Teams: The tightest budget of the four, so larger emoji need resizing.
Checked against each platform's own documentation, except Microsoft Teams, which publishes no stable page for this.
