Twitch 横幅与头像尺寸调整工具 — 全部素材尺寸

Twitch 个人主页横幅为 1200 × 480 像素（5:2 比例），且必须小于 10 MB。频道离线横幅为 1920 × 1080（16:9，与 1080p 直播相同）。视频播放器横幅为 1024 × 576。

上传图片，选择 Twitch 个人横幅（1200 × 480）、离线横幅（1920 × 1080）或面板图（320 × 宽）预设，拖动以定位焦点，然后下载可直接用作横幅、小于 10 MB 的 PNG 或 JPEG。

你的直播日程、社交媒体账号、Discord 邀请、捐赠链接以及一句清晰的行动号召（「关注以观看下次直播」）。离线画面是访客在你未开播时看到的内容，所以请把它当作一块广告牌来对待。

可以。预设涵盖个人资料横幅、离线横幅、视频播放器横幅、面板图片（宽 320 像素）以及用于 OBS 场景的覆盖层 PNG 尺寸——全面焕新频道所需的每一项 Twitch 素材都有。

PNG 最适合带有清晰文字、Logo 和透明叠加层的离线屏幕画面。90% 画质的 JPEG 适用于摄影类横幅，可将文件体积控制在 Twitch 的 10 MB 限制之内，从而加快上传速度。

Your image is uploaded to our server over HTTPS to perform the resize, then automatically deleted right after processing — we never store it long-term or share it with anyone, so unreleased branding, sponsor visuals and stream art stay confidential.

Cover fills the whole preset frame and crops any overflow — good for banners where losing a sliver of edge is fine. Contain shrinks the whole image to fit inside the frame and pads the rest with your background color — essential for a small panel image or sub badge where nothing can be cropped. Stretch forces an exact fit and can distort the image, so reserve it for sources already close to the target ratio.

The tool defaults the background fill to #9146ff (Twitch's brand purple) so padded areas from Contain fit blend naturally into your channel theme. Open the color picker in Settings to swap it for any hex value — useful if your channel uses a custom accent color instead of Twitch's default.

Small assets like sub badges (18×18 up to 72×72) and panel images (320×100) should be PNG to keep tiny logos and text crisp — Twitch also requires PNG for badge uploads. Larger banners and offline screens can use JPG with the quality slider at 85-90 to keep file size well under Twitch's limits.

On the Profile picture preset, a toggle shows a circular safe-zone guide over the square canvas so you can confirm your logo or face survives Twitch's circular avatar crop before downloading. Toggle it off if you just want to see the raw square image underneath.

Pick the Offline screen preset (1920×1080), use Cover fit if your source photo is already widescreen or Contain with a branded background color if it isn't, and export as PNG when the design has sharp text/schedule graphics, or JPG at quality 90 for a photographic background.

这三者共用相同的 1920 x 1080 画布，因为这与标准的 1080p 直播分辨率一致，但它们用于不同的位置：离线画面是频道未开播时访客看到的内容，视频播放器横幅在你的直播无法显示时替换视频播放器，而直播叠加层则用于导入 OBS 作为叠加在实时游戏画面之上的场景素材。尽管像素尺寸相同，也要为每个预设分别导出一个文件，因为每个位置所需的内容各不相同。

频道横幅（1200 x 480）是 Twitch 标准的资料页顶部横幅，用于大多数视图。资料横幅（1920 x 480）是同一位置在更大视口下的加宽版本。两个预设都位于你频道页面的同一处，所以上传时 Twitch 当前要求哪种精确尺寸就选哪种，或者两种都导出，这样无论最终用到哪种尺寸，你的横幅都不会显得被拉伸或加黑边。
