The editor

Bring your own templates. Reuse them everywhere.

Import your existing HTML5 templates — animated, video-backed or static — once, then reuse them across campaigns, languages, A/B variants and even different clients. No template? We can design and build them for you as a separate, one-off service, priced independently from your subscription.

  • Import your own templates — HTML5 with animations, video backgrounds, or static layouts. Bring what you've already built.
  • Reuse across clients and campaigns — one template can power dozens of campaigns for one client, or be shared across your whole roster.
  • Export anywhere — ship as HTML5 bundles, MP4 video, animated GIF or static images from the same source.
  • Languages, variants & overrides — add EN / DE / FR or A/B alongside the original; fine-tune per format where needed.

Need templates designed? We offer template development as a separate add-on — quoted per project, not bundled into the subscription.

Multi-format

From one canvas to every ad slot.

Leaderboard, MPU, Skyscraper, custom programmatic sizes — define them once at team level and every banner you produce ships in all of them. Layouts adapt automatically; trafficking gets exactly what they need.

  • Team format library — define every required size once; reuse forever.
  • Focus-point-aware crops — images recompose around the focal area for each format.
  • Per-format overrides — fine-tune copy or image position only on the formats that need it.
  • PNG, GIF & ZIP delivery — bundled per campaign, ready to hand to trafficking.

After the template is built once, every later campaign reuses it — most of the time above is content edits, not export. Final ZIPs are produced in seconds.

Everything in one place

Built for every step of banner production.

Template library

Reusable HTML templates with text and image placeholders. Build once, use across every campaign.

Brand kit per client

Logos, colors, fonts and components per client. Switch clients and the right kit follows — assets never cross between brands.

Visual annotations

Reviewers pin comments directly on the banner — per format, language and variant.

Media library

Folders, tags, focus points and alt text. Reuse assets across clients and campaigns.

Version history

Every change is snapshotted. Roll back to any previous version with one click.

Client portal

Token-protected page where clients browse approved banners and download files.

Activity log

Full audit trail — who edited, approved, published, and when. Filter by anything.

Client uploads

Time-limited links so clients can drop assets straight into your media library.

Multi-team

Switch between teams, manage roles, invite members. Each team has its own assets.

Client review

A review portal your clients will actually use.

Clients never sign up — no downloads or Slack screenshots to chase. Send one token-protected link: they view live banners, leave pinned feedback, approve or reject by format, and download approved files when they're ready.

  • Pinned annotations — tied to format, language and variant
  • Threaded replies — resolve discussions in context
  • Daily digest emails — never lose track of who said what
  • Time-limited links — expire reviews automatically

Team collaboration

Roles, audit, accountability.

Multi-team workspaces with admin / editor / viewer roles. Every action is logged so you always know who did what, when, and why.

FAQ

The questions agencies always ask.

Something missing? Book a 30-min demo and we'll walk through it on a call.

Do you support animated HTML5 banners?
Yes. Templates are built to your spec — full motion, video backgrounds, or kept static. They render as HTML5 in the editor and can be exported as HTML5 bundles, MP4 video, animated GIF, or static PNG/JPG, depending on what the destination platform needs.
What output formats do you deliver?
HTML5 (per ad-server spec), MP4 video, animated GIF, and static images (PNG, JPG). Approved campaigns are packaged into per-platform ZIP bundles — correct sizes, file weights and naming — ready to hand to trafficking.
Where is our data hosted?
Application data, assets and backups are hosted in Switzerland and the EU. We are GDPR-ready and aligned with the Swiss Federal Act on Data Protection (FADP). Encrypted in transit and at rest.
How is it priced?
One flat plan per agency or team — not per seat. Invite as many editors, reviewers, account managers and external clients as you need without affecting price. Storage is tiered separately above generous defaults, but most teams never hit that line.
Can each client have their own brand kit?
Yes. Every client gets an isolated workspace with its own brand kit — colors, fonts, logos, templates and media library — so assets never cross between clients.
Do clients need an account to review?
No. Reviewers open a single token-protected link in their browser, pin comments directly on the banner, approve or reject by format, and download approved files. No signup, no Slack screenshots, no chasing files.
Do you build the templates for us?
By default, no — you bring your existing HTML5 templates and import them into the platform, then reuse them across campaigns, languages, A/B variants and even multiple clients. If you do want us to design and build templates for you, we offer it as a separate one-off service, quoted per project and priced independently from your subscription.
Can templates be reused across clients?
Yes. Once a template is in the platform, you can reuse it across many campaigns for the same client, or share it across your whole client roster — useful for agencies running similar layouts for different brands. Each campaign keeps its own copy, colors, fonts and assets.
How long does onboarding take?
Typically one to two weeks. We help you import your existing templates, configure your ad-server formats, set up brand kits and train your team — so you ship from day one. If you choose template development as an add-on, that runs in parallel and is scoped per project.

About

Built by Ampersand Labs, a small Swiss studio in Zürich since 2019.

We design, build and operate digital products for Swiss publishers, brands and agencies. Banners by Ampersand grew out of the production work we do day to day — built by the same engineers who use it. No call centres. No outsourcing. Just real humans who answer their own emails.

Pricing

One plan per agency. No per-seat pricing.

We price per agency or team — not per user. Invite as many editors, reviewers, account managers and clients as you need; pricing doesn't move. Bring your own templates or have us build them as a separate one-off — either way, you'll get a tailored proposal within one business day.
