How It Works

Process your images in three simple steps

Upload One or Multiple Images

Select up to 12 JPG, PNG, or WebP files at once for bulk processing. No account or sign-up needed — all processing runs locally in your browser, keeping your channel artwork completely private.

Choose Your Twitch Format

Pick from Profile Photo (512×512), Channel Banner (1920×480), Offline Banner (1920×1080), Video Thumbnail (1280×720), Channel Cover (380×1200), or Emote (112×112). Every format is pre-set to Twitch's exact specifications.

Preview in the editor, adjust fit or crop options if needed, then download. Your images are output at the exact dimensions Twitch requires — ready to upload directly to your channel settings.

Why Choose Imresizer?

Fast, secure, and completely free image resizing

  • Bulk Processing — Up to 12 Images at Once

    Upload multiple channel graphics at once and resize them all to the same Twitch format simultaneously. Perfect for refreshing your entire channel look — banner, offline screen, thumbnail template, and profile photo in one session.

  • All Twitch Formats Pre-Set

    Profile Photo (512×512), Channel Banner (1920×480), Offline Banner (1920×1080), Video Thumbnail (1280×720), Channel Cover (380×1200), and Emote (112×112) — all pre-configured so you never need to look up Twitch's exact pixel requirements.

  • Precise Cropping for Emotes and Icons

    Small-format assets like emotes (112×112) demand pixel-precise cropping. Use the editor's crop tool to center your subject perfectly before downloading, ensuring your emote looks great at the small sizes Twitch displays them.

  • 100% Private — Images Stay on Your Device

    All resizing happens entirely in your browser. Your channel artwork, subscriber emotes, and branded assets are never sent to any server — completely safe for both personal channels and professional brand work.

  • Fine-Tune in the Editor

    After upload you land in the full editor where you can adjust dimensions, change output format (JPG or PNG), set a max file size, and preview before downloading. PNG is recommended for emotes to preserve sharp edges.

  • 100% Free, No Login Required

    No account, no watermarks, no hidden fees. Resize all your Twitch channel assets — full functionality, always free, whether you're a new streamer or a partnered creator.

Frequently Asked Questions

Everything you need to know about image resizing

What are the correct Twitch image dimensions in 2026?
Twitch's recommended image dimensions for 2026: Profile Photo — 512×512 px (1:1); Channel Banner — 1920×480 px (4:1); Offline Banner — 1920×1080 px (16:9); Video Thumbnail — 1280×720 px (16:9); Channel Cover — 380×1200 px; Emote — 112×112 px (also supply 56×56 and 28×28 for all Twitch emote sizes). All of these formats are pre-set in this tool.
What size should a Twitch channel banner be?
The Twitch channel banner (also called the profile banner) should be 1920×480 px at a 4:1 aspect ratio. It appears at the top of your channel page on desktop. Keep critical text and branding in the center 1200 px to ensure it's visible across different browser widths, as the banner is cropped on narrower screens.
What is the correct Twitch offline banner size?
Twitch offline banners should be 1920×1080 px (16:9 ratio). This image is displayed to viewers who visit your channel when you're not live. It's essentially a full HD background image, so use it to display your social links, schedule, or branding. Maximum file size is 10 MB.
What size should Twitch thumbnails be?
Twitch video thumbnails (for past broadcasts, highlights, and clips) should be 1280×720 px (16:9 ratio). This is the standard HD thumbnail size shared with YouTube. A consistent thumbnail template at this size makes your channel look professional and organized across your video library.
What size are Twitch emotes?
Twitch requires emotes in three sizes: 28×28 px, 56×56 px, and 112×112 px. Upload all three when submitting an emote. This tool's Emote preset outputs at 112×112 px — start here and scale down for the smaller sizes. Use PNG format with a transparent background for best results.
What is a Twitch Channel Cover and what size should it be?
The Twitch Channel Cover (also called the profile cover or mobile cover) is a vertical image that appears on Twitch's mobile apps. It displays at 380×1200 px. It's different from the channel banner — design it as a vertical phone-screen layout rather than a wide horizontal banner.
Can I resize multiple Twitch images at once?
Yes. Upload up to 12 images at once and resize them all to the same Twitch format in a single step. This is ideal for batch-preparing thumbnails for multiple VODs or resizing a set of channel graphics all at once.
Should I use JPG or PNG for Twitch images?
For channel banners, offline banners, and thumbnails — use JPG, as it produces smaller file sizes while maintaining good quality for photographic content. For emotes, icons, and any graphics with sharp edges, text, or transparency — use PNG to avoid compression artifacts. This tool lets you choose the output format in the editor.
What is the Twitch profile photo size?
Twitch Profile Photos must be at least 200×200 px but upload at 512×512 px for the sharpest result across all devices. The image is displayed as a circle on your channel page and in chat. Keep your subject centered and leave a small margin around the edges to account for the circular crop.
Is it safe to resize channel art here?
Yes. All resizing happens entirely in your browser. Your channel artwork and brand assets are never sent to any server, making this completely private and safe for professional streamer branding work.
What file formats does Twitch accept for images?
Twitch accepts JPG and PNG images for most channel graphics. For emotes, PNG with a transparent background is required. Maximum file sizes vary by asset type: profile photos and emotes — 10 MB; channel banners and offline screens — 10 MB. This tool lets you set a max output file size in the editor.
Do I need a login to use this tool?
No. Resize images for Twitch completely free — no account, no login, no watermarks. Just upload, choose your Twitch format, and download.
