Step 1
Create account
Sign up with your email and connect a payment method through Stripe. Your card details stay with Stripe — they never touch BidMosaic.
For supporters
Create art together. Support a cause pixel by pixel.
BidMosaic is a shared digital canvas where every pixel you place helps fund a charity or project. Draw something small, design something bold, or leave a message that becomes part of a public mosaic built by the whole community.
The difference
More than just a donation.
Most online donations end the moment you click confirm. BidMosaic does not. The pixels you place stay on the canvas — visible, lasting, sitting next to everyone else's contributions to the same cause.
You are not just sending money into a void. You are leaving a mark. A name. A doodle. A message. A memory. Something you can come back to next week, next month, next year. Something you can show a friend and say I made that.
Your pixels become part of a living artwork that the whole community is building together — and every one of them funds a real cause. You do not just donate. You participate. And what you create stays.
Getting started
Draw and donate in just minutes.
Step 2
Add your art, thoughts, emojis
Draw, type a message, drop in an emoji, or upload an image — express whatever you want on the canvas. Undo, redo, or revert anytime before you commit.
Step 3
Commit when you are ready
Review the live pixel count and total cost, then confirm. Your design becomes part of the mosaic, and your contribution funds the cause.
Mosaic types
Three mosaic types.
Every campaign sets its own rules. Most mosaics use one of these three approaches, depending on how the cause wants supporters to participate.
Type 1
Permanent
Once you commit, your pixels are locked in. Nobody can paint over them, change their colors, or move them — what you place is what stays. Come back next week, next month, or next year, and your contribution will still be exactly where you left it.
Type 2
Dynamic bidding
Your pixels can be overwritten by later supporters, but only if they pay more than you did. Each pixel's price climbs every time it changes hands, so contributing early is the cheapest way to get a spot. If your pixels do get overwritten later, your donation still funded the cause.
Type 3
Uncover / Scratch-off
The charity hides a chosen image under a covered canvas. Each contribution scratches off a section, revealing what is underneath piece by piece. You are not just donating — you are uncovering an image that the whole community is bringing into view together.
Payments and policies
Secure Checkout and Mosaic Policies
Payments
- Payments are processed securely through Stripe; your card details never touch BidMosaic servers.
- Funds you add to your balance are held for future use and are not refundable after purchase.
- Erasing, recoloring, or editing pixels are treated as new purchases at the current price.
Content & conduct
- Hateful, harassing, sexual, illegal, or otherwise inappropriate images, text, or comments will be removed at the discretion of BidMosaic or the organization that set up the mosaic — and removed content is not refunded.
- Pixels overwritten by other supporters, or moderated for any reason, are not refunded. Like paint on a community mural, the cost of placing pixels is non-recoverable once they are committed.
- Repeated abuse may result in account suspension without refund.
