Features

Quick to set up, easy for your client.

Drop in your ZIPs

Drag a folder of ZIPs onto a campaign. Previewer reads each size from the ad.size tag or the file name and puts every banner in place. HTML5, video, images and links to hosted banners all work.

One link for your client

It opens in any browser, on desktop or phone, with nothing to download. The link is private, and when you replace a banner the same link shows the new version.

Backup images in one click

Previewer plays each HTML5 banner, waits for the last frame and saves it as a JPG within the file size limit. For one banner or the whole campaign.

Download all

One ZIP with every banner and its backup image, ready for the media agency.

See when it’s been opened

You can see when your client opened the preview. Link previews in Slack or Outlook don’t count.

Approval status per banner

Mark each size as approved or in review and leave a note for the round.

Your brand on every preview

Your logo, colours and theme on every preview, on your own subdomain. Or show only your client’s logo.
