HTML5 or GIF: which file you need
Animated banners come in two file types. The HTML5 ad is a small web page with a CSS animation: crisp text, smooth motion, small file. Google Ads, ad servers such as Campaign Manager or Adform and affiliate networks accept it, each with its own click wiring. The animated GIF is an image file made of frames: it runs everywhere, including newsletters and websites without an ad server, but is larger for the same length and shows text less sharply.
The rule of thumb: HTML5 for booked display campaigns, GIF for newsletters, your own website, marketplaces and platforms that do not accept HTML5. myfeedr builds both from the same animation, so you do not have to decide up front.
- ✓HTML5 ad: one file per size, 150 KB under the IAB standard, click wired per platform, text stays sharp on retina screens.
- ✓Animated GIF: one image file per size, 150 KB target, runs without an ad server, repeats stored in the file’s loop counter.
- ✓Both with the same effect, speed and number of loops, and an end frame with logo, headline and button.
The effects: Reveal, Product focus, Two scenes, Price highlight
Each effect is a fixed sequence of six to nine seconds that runs at three speeds and repeats up to three times. Reveal builds up logo, image, headline and button one after another and is the safe default. Product focus zooms gently into the product image and then sets the text. Two scenes alternates between brand message and offer. Price highlight keeps everything calm and lets badge and price jump in before the button arrives.
The studio preview plays the chosen effect live in every display size, with a replay button per banner. Social, newsletter and Google responsive sizes stay static, in the preview and in the export. What runs there is exactly the file exported later: the same keyframes, the same duration.
What stays the same across sizes
An animated banner has to work in 300×250 just as well as in 728×90 or 160×600. myfeedr gives each size its own layout, keeps text inside the safe zone and adjusts font sizes automatically so nothing overflows. The animation runs on the same elements regardless of where they sit in the size.
Platform limits are built in: 15 seconds under the IAB standard, 30 seconds in Google Ads, at most three loops, then the end frame stays. Where a platform allows less, the export caps the loops and states the actual value in the README.

Frequently asked questions
- Do I need animation software?
- No. The effects are fixed sequences you select in the studio. There is no timeline and no keyframes to set; myfeedr handles the motion for every display size.
- Can you animate my existing banners?
- myfeedr rebuilds the banners from your website so all sizes match. Existing artwork cannot be imported; the logo, colours, product images and copy of your site are the basis.
- How long can an animated banner run?
- 15 seconds under the IAB standard, 30 seconds in Google Ads, with at most three loops each. myfeedr enforces the limits per target platform automatically.
- Which file do I get?
- One HTML5 ad per size as a ZIP for ad servers and networks, and one animated GIF per size for newsletters and websites. Both from the same animation.
- Does the animation run on phones?
- Yes. HTML5 ads are pure CSS and run in every mobile browser, GIFs do anyway. Mobile sizes such as 320×50 and 320×100 are part of the set.
