How flexible is your digital signage software?

Polotno isn’t another off-the-shelf digital signage design tool. It’s a flexible editor framework you embed into your platform, so you control exactly how content is created, customized, and exported. You’ll do the integration work – but you get freedom no template system can match.

Digital signage design software that doesn’t limit you

When you set up a digital signage system – handling everything from content creation to scheduling and playback – you face a familiar trade-off.

You can buy a turnkey platform with rigid templates. It’s fast to deploy but severely limits not only what your customers can create, but also how you define workflows, approvals, permissions, and business rules. Any change beyond the defaults – like customizing content scheduling, controlling who can edit specific elements, or adapting designs to different screen formats – usually means frustration, support tickets, or messy workarounds.

You can assemble your own stack, building or integrating an editor and rendering pipeline from scratch. This gives you total control but costs months of engineering time, creates endless edge cases, and locks you into constant maintenance.

Polotno is different.

It’s a fully embeddable editor and rendering engine you integrate into your system and processes. You decide exactly how flexible it should be – what tools users can access, which parts of a design stay locked, how permissions are enforced, where assets live, and how content flows through scheduling and publishing.

Whether you need high-resolution images, dynamic previews, or fully rendered videos ready for broadcast on displays, Polotno handles the design and rendering layer – so you can focus on everything else that makes your signage solution stand out.

Real-world use cases for Polotno SDK for watermarking


Print-on-demand platforms

Automatically apply watermarks to custom designs before users place orders. Ensure every mockup is protected without limiting design flexibility. For example:

  • Apply different watermarks for free and paid users.

  • Add dynamic elements like the user’s name or design ID directly onto the watermark.

Digital marketplaces

Protect creator-generated content by dynamically applying watermarks to images, previews, or downloadable assets. Customize watermark opacity based on membership level or user permissions.

Enterprise security tools

Add confidential stamps, dynamic watermarks, or traceable codes to sensitive documents processed entirely within your secure network—no third-party processing required.

Custom design apps

Let users add their own watermarks, adjust placement, or even upload logos for branding—directly within your app. Offer live previews and dynamic editing options for a premium user experience.
