Carefully designed cover images become blurry, get cropped, or fail to upload because the file is too large. Every platform has different requirements: Instagram recommends 1:1 or 4:5, YouTube needs 16:9, Twitter wants 3:1 headers — just figuring out the specs is a headache.
This guide compiles all major platform specs in one place. Combined with Suried Tools' batch compression, efficiently produce cover images that fit every platform — no more repeated revisions.
01 Domestic Platform Cover Image Specs
Xiaohongshu note cover: recommended 1080×1440px (3:4 portrait) or 1080×1080px (1:1 square), file size ≤ 10 MB. The platform re-compresses on upload, so source files of 500 KB–1 MB at ~85% quality work best.
Douyin video cover: recommended 1080×1920px (9:16 portrait). The system auto-captures from video, or you can upload manually. Suggested ≤ 2 MB, JPG or PNG. Note that approximately 15% of the top and bottom may be obscured by platform UI.
WeChat Official Account headline cover: recommended 900×383px (2.35:1), file ≤ 5 MB. Secondary article cover 200×200px (1:1). Since display size is small, under 400 KB is sharp enough. Bilibili video cover: recommended 1146×717px (16:10), ≤ 2 MB.
All platforms re-compress uploaded images. Compressing to a sensible size (not the max limit) before uploading actually gives better results after the platform's compression — because you control the first round of quality parameters.
02 International Platform Cover Image Specs
Instagram posts: recommended 1080×1350px (4:5) for maximum display area, 1080×1080px (1:1) is classic. Stories 1080×1920px. Profile picture 320×320px. All images suggested ≤ 1 MB.
YouTube thumbnails: must be 1280×720px (16:9), minimum width 640px, ≤ 2 MB, JPG/PNG/GIF/BMP. Channel banner 2560×1440px. Twitter/X header 1500×500px (3:1), tweet images optimal at 1600×900px (16:9).
Facebook cover photo 820×312px (desktop), 640×360px (mobile) — design for both aspect ratios. LinkedIn background 1584×396px, post images 1200×627px. Universal recommendation: use sRGB color space JPG for all platforms.
03 Batch Compression Workflow: One Session, Multiple Platforms
An efficient approach: design one source file at the largest needed dimensions (usually 2048px wide covers all platforms) in Photoshop/Figma, then export multiple cropped versions for different platforms.
After exporting, drag all versions into Suried Tools for batch compression. JPG format at 80–85% quality generally achieves the best balance of quality and file size. If a specific platform has strict limits (e.g., ≤ 500 KB), set a target size individually.
When saving, use platform names as suffixes: cover-xiaohongshu.jpg, cover-douyin.jpg, cover-youtube.jpg — easy to manage long-term and prevents accidental uploads to the wrong platform.
For text-heavy covers (like tutorial content), use PNG compression instead of JPG — JPG's lossy compression causes noticeable color fringing and jagged edges around text.
FAQ
Why does my cover image become blurry after uploading?
Two common causes: 1) Image dimensions too small, stretched by the platform causing blur; 2) File too large, platform aggressively re-compresses causing quality loss. Solution: create at recommended dimensions, then pre-compress to a reasonable size (slightly under the limit) to minimize the platform's re-compression impact.
Should I use JPG or PNG for cover images?
Photo-based covers → JPG, smaller files with rich colors. Graphic covers with lots of text/lines/solid colors → PNG, better sharpness. If the platform supports WebP, prefer it — combines JPG's small size with PNG's quality.
What if the platform crops faces in my cover image?
During design, keep core content (faces, important text) within the center 60–70% "safe zone." Different platforms crop differently — some from top/bottom, others from sides — leave enough margin to ensure safety across all platforms.
Can one image work for all platforms?
Not really. Platform aspect ratios vary widely (1:1 vs 16:9 vs 2.35:1), forcing one image means inevitable cropping. Better to create one "universal composition" (centered subject, clean background), then crop into different aspect ratio versions. The extra work is actually minimal.
Does dark mode affect how cover images display?
Yes! White-background covers are glaring in dark mode, while dark covers may not stand out in light mode. Use mid-tone or sufficiently contrasted color schemes that look good in both modes.
