How to Resize Images for YouTube, Discord, Twitch, and Spotify (Free, 2026)

Every content platform has different image size requirements, and none of them tell you clearly what happens when you upload the wrong dimensions. YouTube crops your banner. Discord squishes your avatar. Twitch rejects emotes that are even one pixel off.

This guide has the exact pixel dimensions for YouTube, Discord, Twitch, and Spotify — plus how to resize any image to match them in under 30 seconds using a free browser tool. No Photoshop, no Canva, no app install.

YouTube Image Sizes — Every Dimension You Need

Channel banner: 2560 x 1440 pixels. YouTube displays this differently on TV (full width), desktop (middle 1546x423 safe area), and mobile (middle 1235x338). Design your banner so the important content stays in the center 1235x338 zone.

Video thumbnail: 1280 x 720 pixels (16:9 ratio). Must be at least 640px wide. Under 2MB. JPG, PNG, or GIF. This is the single most important image on YouTube — it determines whether people click.

Profile picture: 800 x 800 pixels. Displayed as a circle, so keep important content away from the corners.

Video watermark: 150 x 150 pixels. Transparent PNG recommended. This is the small logo that appears in the bottom-right corner of your videos.

To resize any image to these dimensions: open the free image resizer, drop your image, enter the width and height (e.g., 1280 x 720 for thumbnails), and download. If your source image has a different aspect ratio, pair it with the image cropper first to cut it to 16:9 before resizing.

Discord Image Sizes — Avatars, Banners, and Server Icons

User avatar: 128 x 128 pixels minimum (Discord displays at various sizes up to 256x256). Upload at 512x512 for best quality — Discord will scale it down.

Profile banner (Nitro): 960 x 540 pixels (or 600 x 240 recommended). Nitro subscribers can upload an animated GIF. Free users get a solid color.

Server icon: 512 x 512 pixels minimum. Displayed as a circle in the server list. Keep logos centered and away from edges.

Server banner (boosted): 960 x 540 pixels. Available for servers with Boost Level 2+.

Emoji/sticker: Under 256KB. Discord recommends square images. Custom emojis display at 32x32 in chat and 48x48 in the emoji picker.

Discord is strict about file size — if your resized image is still too large, run it through the image compressor to get under the limit without visible quality loss.

Twitch Image Sizes — Emotes, Profiles, and Panels

Subscriber emotes: You must upload three sizes: 28x28, 56x56, and 112x112 pixels. All three are required. Twitch will reject your submission if any size is missing or has the wrong dimensions. Transparent PNG background recommended.

Profile picture: 256 x 256 pixels minimum (800x800 recommended). Displayed as a circle.

Offline banner: 1920 x 1080 pixels. Displayed when your stream is offline.

Video player banner: 1920 x 480 pixels. The top banner area of your channel.

Panel images: Max 320px wide. No height limit, but keep them under 600px tall for clean layout. PNG or JPG.

Twitch emotes are the trickiest because you need exact pixel dimensions at three scales. Resize your emote design to 112x112 first (the largest size), verify it looks good, then resize to 56x56 and 28x28. Check that fine details are still readable at 28px — if not, simplify the design.

Spotify Image Sizes — Cover Art and Profile

Album/playlist cover art: 3000 x 3000 pixels (square, 1:1 ratio). Minimum 640x640. JPG format. Spotify displays this at many sizes — from tiny 64x64 in playlists to full-screen 640x640 on desktop. Upload at 3000x3000 for maximum quality everywhere.

Artist profile image: 2660 x 1140 pixels (header) or square for avatar. The header image has a safe zone in the center — important content should stay centered.

Podcast cover: 3000 x 3000 pixels. Square, same as album art. RSS feeds often require this as well.

Spotify cover art at 3000x3000 can be large — if your source image is smaller, the resizer will scale it up. For best results, start with the highest resolution source you have. Scaling up from 500x500 to 3000x3000 will produce a noticeably blurry result. If your source is low-resolution, consider using 1500x1500 as a compromise.
