Free online streaming tools
OBS overlay builders, Twitch panel makers, stream schedules, and creator utilities.
Four graphics tools that produce the PNG files a stream layout is actually made of, each drawn on an HTML canvas in your own browser and exported straight from it. The OBS Overlay Maker is a layered editor at 1920x1080, 1280x720 or 854x480, with rectangle, text and image layers that carry their own opacity, rotation, corner radius, stroke and lock state, plus a template gallery that starts you from a webcam frame, an alert box or a full scene rather than an empty canvas. You can drop your own images into a layer, including HEIC shots straight off an iPhone, and the export writes a transparent PNG sized exactly to the canvas so it drops into an OBS image source without scaling. The Twitch Panel Maker is fixed to 320 pixels wide because that is the width Twitch renders channel panels at, so what you design is what viewers see; you pick a header and body, set alignment, border width, corner radius and a gradient or flat theme, start from prewritten About me, Schedule, Chat rules, Donate, Links, Setup, FAQ or Sub perks copy, and export at your display's pixel ratio so the text is not soft on a high-DPI screen. The Stream Schedule Maker lays out a week of slots with a timezone line printed on the graphic, then exports the same design at four sizes — 1040x820 for a channel panel, 1200x675 for Twitter, 1080x1080 for an Instagram post and 1080x1920 for a story — from one shared draw routine, so the preview and every export match instead of drifting apart. The Twitch Emote Maker takes one image and resizes it to 28, 56 and 112 pixels, which are the three sizes Twitch requires for a chat emote, plus 128 px for Discord and 7TV and 300 px for BTTV and FFZ, keeping transparency intact through a PNG re-encode. Nothing here uploads your artwork and nothing is watermarked.

How to choose the right tool
These four do not overlap, so pick by what you are filling in. If a viewer sees it under the video player, you want the Twitch Panel Maker, and its fixed 320 px width is the reason to use it rather than a general image editor where a guessed width gets resampled by Twitch. If a viewer sees it over the video, that is the OBS Overlay Maker: build at the same resolution as your canvas in OBS, keep the background layer transparent, and export once per scene rather than baking several scenes into one file. If it is telling people when you go live, the Stream Schedule Maker is the one that exports the same artwork at panel, Twitter, Instagram and story sizes in one sitting, which saves recreating a schedule graphic four times for four aspect ratios. If it is going in chat, use the Twitch Emote Maker and start from a square source at 300 px or larger, because downscaling to 112, 56 and 28 works and upscaling to them does not. Design the emote so the 28 px version still reads at a glance, since that is the size most viewers see most of the time.
Frequently asked questions
Do the exported files have a watermark or a size limit?
No to both. Every export is a plain PNG drawn from the canvas in your browser and downloaded directly, with no badge, no logo and no cap on how many you make. There is no account, no free tier and no export queue, because there is no server involved in producing the image. The only practical limit is your browser's memory, which matters only at 1080p with many large image layers in the overlay editor.
Why is the panel maker locked to 320 pixels wide?
Because Twitch renders channel panels in a 320 px column. Design at any other width and the platform rescales your image, which softens text and thin borders in a way that is very visible at that size. Locking the width means the preview is pixel-accurate to what viewers get. Height is free, so a panel grows with the body text you type. The export is rendered at your device pixel ratio, so a 2x display gets a 640 px-wide file that still lays out as 320.
What resolution should I build my OBS overlay at?
The same as your base canvas resolution in OBS, which for most streams is 1920x1080. The editor offers 1080p, 720p and 480p for that reason. Matching resolutions means the PNG lands in an image source at 100 % scale with no resampling, keeping one-pixel borders and small text crisp. If your canvas is 1080p but you output at 720p, still design at 1080p and let OBS do the single downscale at the end.
Which emote sizes does Twitch actually need?
Three: 112x112, 56x56 and 28x28, all PNG with transparency, and each file has to stay under 25 KB. The tool generates all three from one source image in one pass, and adds 128 px for Discord and 7TV and 300 px for BTTV and FFZ since most streamers upload the same artwork to all of them. Flat shapes with strong outlines survive the 28 px version; fine gradients and thin detail do not.
Can I save a design and come back to it later?
Export the PNG before you close the tab. These editors hold the layout in page memory while you work, so a refresh starts you over from the template gallery. That is a consequence of there being no account and no server-side storage: nothing about your design is transmitted or kept. For an overlay you expect to revise, keep the source images you dropped in and rebuild from the same template rather than relying on the tab staying open.
