Compress Image for Discord | MiniPx — Free, Fast & Private
Discord has a 10MB file upload limit for free users, 50MB for Nitro Basic subscribers, and 500MB for full Nitro subscribers. Screenshots, edited images, and high-resolution photos can easily exceed the free tier, and batch uploads exceed it even faster. MiniPx compresses images to fit comfortably within Discord limits.
For chat images: JPEG + Smart + 1920px produces files of 200-600KB that look sharp in Discord chat windows. There is no need to upload multi-megabyte originals when Discord displays images at much smaller sizes anyway.
Discord server icons should be at least 512x512 pixels, square aspect ratio. Profile pictures (avatars) display at 128x128 but upload at higher resolution for quality. Use PNG for icons with transparency or sharp edges.
Custom emoji uploads need to be under 256KB and square — that file cap and the JPEG/PNG/GIF/WebP format list are Discord's actual rules, while the popular 128x128 canvas is just convention, a distinction the Discord emoji size guide unpacks. MiniPx can resize and compress custom emoji to meet this requirement while keeping them recognizable at small display sizes.
All processing is private — your memes, screenshots, and personal photos are never uploaded to any server except Discord itself when you choose to share them.
