How to make a fundraising thermometer
Enter your goal and the amount raised so far, add an optional campaign name, and pick a color. The preview updates as you type. Download the PNG for printing or sharing, the SVG if you want to scale it to poster size without losing sharpness, or copy the embed snippet to put it on your website.
The preview and downloads run in your browser: nothing you type is uploaded when you download the PNG or SVG, and no account is needed. The embed snippet works differently — it loads the image from our server, so the goal, amount, and campaign name in the snippet travel in the image address and appear in standard server logs each time the image loads. When your total changes, come back, update the numbers, and download a fresh image — or use a Donairo page if you'd rather the progress update itself.
Frequently asked questions
Is this fundraising thermometer generator really free?
Yes. There's no signup and no watermark on your downloads. The preview and downloads are generated entirely in your browser; if you use the embed snippet, the numbers and campaign name you chose are part of the image address, so they reach our server whenever the embedded image loads.
Can I print it as a poster?
Yes. Download the SVG and print at any size without losing sharpness — it scales cleanly to poster dimensions. The PNG downloads at double resolution, which prints well up to roughly A3.
How do I update it as donations come in?
The image is a snapshot. Come back, change the raised amount, and download or copy a fresh version — or, if you embedded it, edit the numbers in the snippet's image address. For a display that updates on its own as people give, a Donairo page does that automatically.
Can I embed it on my website?
Yes — copy the embed snippet and paste it into your site or blog. It renders as an image and links back to this tool, and you can change the goal, raised amount, label, and color right in the image address.
Does it update automatically when someone donates?
No — it shows the numbers you typed in, so you update it by hand. If you want live progress, a free Donairo page shows your goal and total moving in real time as donations arrive.
