Frame
Compare the rendered banner with the dimensions in your creative brief. Common formats such as 300 × 250 or 728 × 90 are examples, not a universal acceptance test.
All use cases
For creative review
Test HTML5 banner ads online before handoff.
When a banner is already built as browser-ready HTML, a focused preview helps creative, marketing, developers, and QA inspect the actual output. This use case is for browser-ready HTML5 banner files or ZIP exports only. Upload one self-contained HTML file or a ZIP with index.html and its local assets, then check the parts of the banner that a browser can show before the final platform workflow.
Review lens
What to check in the banner preview
A useful banner review is narrow: confirm that the uploaded artifact renders at the intended size and that its visible and clickable behavior survives a fresh browser load.
Assets
Confirm that CSS, JavaScript, images, fonts, and other local files load from the relative paths used by index.html or the single-file export.
Destination
Activate the intended CTA or click area, check that it points to the expected destination, and note any browser behavior that needs a separate campaign test.
A real moment for the page
A browser link makes the next conversation concrete.
Creative review
Give a designer or marketing reviewer a browser link to inspect the message, hierarchy, animation, and intended banner dimensions instead of a screenshot.
Developer smoke check
Open the exported HTML or ZIP in a fresh tab, reload it, and catch missing assets, incorrect paths, or state that only worked in the local setup.
Client or team handoff
Share one preview URL with the format, target viewport, expected click destination, and a short list of what the reviewer should confirm.
Why this handoff works
Keep the useful part close to the artifact.
Review the rendered artifact
Inspect the browser-ready banner that will be handed off, rather than asking reviewers to reconstruct it from source files or a static image.
Catch path and reload issues
A fresh browser load makes missing CSS, JavaScript, images, fonts, and fragile client-side states easier to spot before delivery.
Keep the handoff specific
A preview link can carry the creative size, click expectation, and review question without being mistaken for a final ad-platform submission.
A three-step workflow
From the right files to the right reaction.
- 01
Package the browser-ready files
Use one self-contained HTML file, or a ZIP with index.html at the expected level and every local CSS, JavaScript, image, font, and data file it references. Use relative paths.
- 02
Check size, links, and reloads
Open the preview in a fresh browser tab, compare it with the intended dimensions, check desktop or mobile behavior as needed, activate the click link, and reload the page.
- 03
Share the review link
Send the URL with the banner format, browser or viewport used, expected destination, and the specific feedback you need before the next handoff.
Know the boundary
A preview is useful because it is honest.
HTMLShare publishes browser-ready static output. Keep builds, source tools, private access, live data, and production operations in the systems built for them.
No Google, IAB, or ad-server compliance validation
This workflow does not validate Google Ads, ad-network compliance, IAB policy, ad-server behavior, or platform submission requirements. Check the current requirements of the destination platform separately.
No third-party ad-tag certification
The preview can show the uploaded static files in a browser, but it does not validate third-party ad tags, trackers, click macros, reporting, or ad-serving behavior.
Preview is not final delivery
Use the link for browser review and team handoff. Final packaging, approvals, tracking, accessibility, landing-page checks, and platform submission remain in your campaign workflow.

HTML5 banner ad preview FAQ
How do I test HTML5 banner ads online?
Export a browser-ready HTML file or ZIP, include index.html and its local assets, publish a preview link, then check the intended dimensions, asset loading, click behavior, and fresh-page reload in a browser.
What should I upload for an HTML5 banner preview?
Upload a self-contained HTML file when its CSS and JavaScript are inline. Use a ZIP when the banner references local assets, and keep index.html plus its asset folders at the paths the HTML expects.
Can I check the banner dimensions and click link?
Yes. Compare the rendered banner with the dimensions in your creative brief and activate its intended link in the browser. This is a review of the uploaded output, not a guarantee that a network will accept the size or tracking setup.
Does this validate Google, IAB, ad-network, or ad-server requirements?
No. HTMLShare does not validate Google Ads, ad-network compliance, IAB policy, ad-server behavior, third-party ad tags, or platform submission requirements. Use the destination platform's current documentation and testing process for those checks.
Can I share the banner preview with a client?
Yes. Share the preview URL with the format, target dimensions, expected click destination, browser used, and a focused review question. Remove secrets and sensitive campaign data first because a noindex link is not access control.
