This page explains how to upload ad creatives and what technical requirements you need to meet.

Before You Upload

All creatives must follow IAB standards.
Make sure your files meet these requirements:

  • File types: .png .jpeg .jpg .gif .bmp and .zip (with HTML inside)
  • Max file size: 500 KB
  • Destination URL: Must use https (UTM tags recommended for tracking)

Good to know:

  • We’ve transitioned our third-party creative hosting from Adform to OptOut
  • Uploading creatives is now faster
  • Creatives may take up to 5 minutes to appear in preview after upload
  • Existing Adform creatives are still supported, including updates to landing page URLs for image-based creatives

How to Upload

Go to the Ad Creative tab in the Kobler platform to upload your files.

If you use an ad server, insert your ad tags under "Ad tags" in the Creative tab.
We support OptOut, Bannerflow, Google (DoubleClick), SeenThis, Zuuvi, and more.

Video ads must be compressed to 500kB before uploading.
We recommend using SeenThis or Adserve for compression.

Using a different provider? Contact us at support@kobler.no and we’ll help you get set up.

Ad Formats

We support a wide range of ad formats across Norway, Sweden, and Denmark, from standard display to high-impact formats.
High-impact formats are currently available in Norway only.

All available formats and placements can be explored in real time in the Kobler platform under Inventory.

Reach your audience across 339 editorial media sites in the Nordics.

High Impact – 1920x1080 (Responsive)

We now support a full-screen High Impact format, also known as midscroll or interstitial (1920x1080).

NB! This format is currently only supported in Norway through third-party ad tags.

Creative requirements

  • Creatives/tags must be responsive and use the full viewport (width: 100vw, height: 100vh).

  • Creatives must work in both landscape and portrait orientation. All key elements must remain visible within the safe areas: 528x940px (portrait) and 1400x940px (landscape).

Platform & campaign setup

  • When uploading, manually set the format to 1920x1080.

  • Make sure to verify your creatives using the “View full-scale” preview in the platform.

  • High impact placements have a higher floor price. Run these creatives in a separate targeting within the campaign and adjust the CPM accordingly.

Please contact us for guidance on the setup

Managed Campaigns

If Kobler manages your campaign, send your creatives to cs@kobler.no at least 3 business days before launch. Need to run multiple ad versions? Check our pricing page for hosting options.
