Free Twitch badge resizer

Drop in one square image and get every PNG Twitch asks for: sub and bit badges at 18, 36 and 72 px, and channel point icons at 28, 56 and 112 px. Transparency is kept, and each size is shown at 100% on a dark and a light chat background.

Everything happens in your browser. Your artwork never leaves your computer.

Runs in your browser. Your image is processed on your own device. Nothing is uploaded to a server, there is no account to make, and the tool makes no outside requests.

How to use it

  1. Add one square image

    A transparent PNG works best, at 512 × 512 px or larger. If your image is not square, choose whether to crop it or pad it with transparency.

  2. Check the previews

    Each size appears at its real pixel size on a dark and a light chat background, so you can see whether the shape still reads at 18 px.

  3. Download the files

    Download each PNG one at a time, or take everything in one ZIP. The tool warns you if a sub badge file is over Twitch's 25 KB limit.

  4. Upload to Twitch

    Sub badges go under Monetization › Subscriptions › Subscriber Badges. Bit badges go under Monetization › Bits & Cheering › Bits Tier Badges. Channel point icons go under Viewer Rewards › Channel Points.

Small icons need simple shapes. Thick outlines, one or two flat colours and no fine detail survive the trip down to 18 px much better than gradients do.

Want a matching set already designed? Browse the Sprout Badges and Medal Badges packs, or read the sub badge size guide for the full upload steps.

Questions

What sizes does Twitch need for sub badges and bit badges?

Three square PNG files: 18×18, 36×36 and 72×72 pixels, with a transparent background. Sub badge files can be at most 25 KB each.

What sizes do channel point icons need?

Three square PNG files: 28×28, 56×56 and 112×112 pixels.

Is my image uploaded anywhere?

No. The resizing happens inside your browser with your own device. The page makes no upload requests and does not need an account.

Will my sub badges fit the 25 KB limit?

Almost always, because a 72×72 PNG is small. The tool checks every file and warns you if one goes over. If that happens, simplify the artwork and use flat colours.

Will transparency be kept?

Yes. If your source has a transparent background, the PNG files keep it. A JPG source has no transparency to keep, so it will come out with its solid background.
