Part 1. Discord Emoji Size

Since Discord is a versatile messaging app, sending images through text channels and private messages can be done in multiple ways. As such, file attachments and custom emojis have different standards.

To learn the difference between them, please read the file size limit and the recommended resolution for the files used in these channels.

Sent Images as Attachments

When sending images as attachments to text channels or voice call text chats. Discord has separate attachment file size limits for free users and Discord Nitro subscribers.

For Discord free users, the file size limit is at 8MB. On the other hand, Discord Nitro subscribers have a 100 MB attachment limit. For images, 8MB is usually enough, but expect lower quality.

If your Discord image size is larger than 8MB, you can use a tool to compress image online before uploading to Discord.

Note that these file size limits apply to more than just images. They also apply to all media files, as these limitations pertain to all attachments, not just images.

Custom Discord Emoji

For Discord moderators and server owners who want to personalize their channels, you can add custom Discord emojis to your channel settings. Although different from regular attachment sharing, custom emojis may also be regular images. However, they follow specific measurements.

Custom Discord emojis have a maximum size of 128x128 pixels and a maximum file size of 256 KB. When these custom emojis are sent in text channels, the messaging app will automatically scale them down to 32x32px.

With these measurements out of the way, we hope that sending images in Discord will now be much smoother and easier for our readers. These are highly important, as exceeding these limitations will prevent your image from being sent.

Part 2. Does Discord Reduce Image Quality

Does Discord compress image or reduce photo quality?

Yes, they do. Images sent through Discord are of lower quality because the messaging app optimizes for shorter load times and lower bandwidth usage. These ultimately result in faster image transmission, whether on text channels or in voice call chats.

In extreme cases, Discord also offers an optional Low Quality Image Mode that compresses images more aggressively to reduce their file size. This is usually popular when sharing images over slow connections or on Discord mobile, as the quality isn't as noticeable on smaller screens.

Given Discord's limitations with emojis and images, using a reliable Discord emoji size converter is a smart option. This is because Discord custom emojis are more restrictive regarding file size.

To learn the best option for sending large images in Discord without sacrificing quality, the next section highlights the most reliable online image compressor.
