Frequently asked questions

What size do Discord emojis need to be?

Discord requires custom emojis to be exactly 128 × 128 pixels and under 256 KB. They are displayed at 32 × 32 pixels in chat (or 22 × 22 inline with text). Supported formats are PNG, JPEG, WebP, and GIF. Source: Discord Support (verified August 2026).

Why does my Discord emoji upload fail?

The most common causes are: (1) the file is over 256 KB — hidden EXIF metadata often inflates file size invisibly, (2) the image is not square (Discord silently squishes non-square images), or (3) the format is unsupported. This tool strips metadata, forces a perfect square crop, and guarantees the output is under 256 KB.

Does this tool preserve transparency?

Yes. If your source image has transparent areas (e.g., a PNG with alpha channel), this tool preserves them in the output. The Discord chat preview shows your emoji against both dark and light backgrounds so you can verify transparent edges look correct.

What is the difference between Discord emojis and stickers?

Emojis are 128 × 128 px (max 256 KB) and appear inline in chat messages. Stickers are 320 × 320 px (max 512 KB) and appear as standalone images. This tool is designed for emojis, not stickers.

Are my images uploaded to a server?

No. All image processing happens locally in your web browser using HTML5 Canvas. Your images never leave your device. There is no server upload, no cloud storage, and no data collection.

How many custom emojis can a Discord server have?

A default Discord server has 50 static emoji slots. Nitro-boosted servers can have up to 250 total emoji slots depending on boost level. Each slot accepts one 128 × 128 px image.

Does this tool work on mobile browsers?

Yes. The tool works in Chrome, Firefox, Safari, and Edge on both desktop and mobile devices.

When Should I Use This Tool?

Use this tool whenever you need to create or update a custom emoji for a Discord server:

New server emoji: You have art, a logo, or a reaction image that needs to be cropped and sized to 128×128.
Upload errors: Discord is silently rejecting your emoji upload because hidden metadata pushes the file over 256 KB.
Dark mode visibility: Your emoji looks fine on a white background but disappears on Discord Dark Mode because of transparent dark outlines.

Troubleshooting Common Discord Emoji Errors

Upload fails silently: Usually the file is over 256 KB. EXIF metadata from phone cameras can add 50–100 KB invisibly. This tool strips all metadata.
Emoji looks squished: The source image was not square. This tool enforces a 1:1 crop before resizing.
Emoji invisible on dark theme: Transparent emojis with dark outlines blend into Discord Dark Mode. Use the preview toggle to verify visibility.

This tool uses the HTML5 Canvas API and works in all modern browsers:

Google Chrome 90+
