Reach developers while they work
Every day, developers, testers and IT people open this site to encode and decode Base64 - in the middle of building something. Put your product next to the tool they are using: banner or text ad, booked online in minutes, from a few dollars a week.
Where your ad appears
The left rail sits next to the converter on every tool page (on phones it moves under the tool). The bottom places are under the converter on every page.
Left rail - top rectangle
First thing on the left of every tool page, next to the converter. Highest visibility.
Left rail - sponsored links You clicked this place
Up to four short text ads under the top rectangle. Developers click text ads more than banners.
Left rail - half page
Tall banner that stays in view while visitors scroll (sticky).
Bottom banner
Wide banner under the converter on every page. On phones the 320 x 100 version is shown.
Bottom sponsored links
A row of up to six text links above the page footer.

How booking works
- Create a free advertiser account (company name and e-mail).
- Choose a place, dates and pricing, and upload your banner or write your text ad. You see the price at once.
- We check the ad, usually within one business day. You pay nothing before it is approved.
- Pay the invoice by PromptPay QR, by bank transfer or card.
- Your ad goes live on the start date. Follow views and clicks in your dashboard.
Ad specifications
- Banners: PNG, JPEG, GIF (still) or WebP at the exact size of the place - or exactly double for sharp screens.
- File size: 150 KB (half page 200 KB); double-size images may be twice as big.
- Bottom banner: 728 x 90, plus an optional 320 x 100 version for phones.
- Text ads: headline up to 40 characters, description up to 90, and the address you want to show.
- Link: a secure https:// page. We add UTM tags unless you turn them off.
- Alternative text for banners, for screen readers - accessibility matters to our visitors too.
What counts and what is billed
- A view counts when at least half of the ad was on screen for one second (the industry's "viewable impression").
- A click counts once per visitor and ad within 30 minutes; repeats are shown as invalid and never billed.
- Robots, link previews and crawlers are never counted.
- Ads and images are served from this site: no third-party scripts, no tracking cookies, fast pages.
- Links carry
rel="sponsored", as search engines require for paid links.

We do not accept: gambling, adult content, weapons, drugs, cryptocurrency investment schemes, "get rich" offers, malware, cracked software, misleading claims, ads that imitate system messages or download buttons, and pages that ask for passwords or payment details under false pretences.

Questions from advertisers
What happens if my ad is not approved?
You get a note saying what to change. Fix it and send it again - you pay only after approval, so nothing is lost.
Can I change the ad while it runs?
Yes. A changed ad is checked again (usually within a business day) and is paused until it is approved.
Which payment methods do you accept?
PromptPay QR (Thai banking apps), bank transfer and credit or debit card. Every booking is paid in advance; you get an invoice and a receipt as PDF.
What if the budget of a CPM / CPC campaign is not used up?
The campaign runs until its end date. Unused budget can be moved to a new campaign or refunded - just ask.
Do you offer agency or long-term deals?
Yes - 3+ and 6+ month bookings get a discount automatically. For larger packages write to support@example.com.
Ready when you are
Booking takes about five minutes. You pay after approval.
