Does Discord Compress Images

Similar to other social media platforms, Discord can automatically compress images when you upload ones that exceed its limit. Why does Discord compress pictures? This is to optimize Discord’s server storage, speed up upload times, and reduce bandwidth usage.

Please note that image compression can cause the image to have low quality or artifacts. How can you get relatively good-quality photos in Discord? You should adjust the image size in advance to meet Discord's requirements. Or, you can wrap your photos into a ZIP file. In this post, I mainly recommend some good image compressors and show you detailed steps to compress images for Discord.

About Supported Discord Image Size Specs

Before getting to learn ways to compress photos for Discord, let’s master the image size specification supported by Discord. In addition to supporting sending pictures, Discord supports many image types, ranging from avatars and banners to emojis, stickers, and embed thumbnails.

Generally, the image size for avatars and server icons is no larger than 8 MB. For Discord emojis, the size should be limited to 256 KB. The embedded thumbnail should be smaller than 5 MB. For others, the largest image size is no larger than 10 MB.
