What our clients say about us
Integrating IMG.LY’s editor meant we didn’t have to build or maintain a complex editing layer ourselves. That kept our team focused on our core AI ad engine and saved us countless development hours — while still giving our customers the ability to polish and customize creatives at scale.
Hikari Senju
CEO, Omneky
With IMG.LY we built a central creative portal that now powers over 140 dealer campaigns across multiple automotive brands. Before this, asset creation was slow and inconsistent.
Martin Röhr
Product Owner, Digitas
By embedding IMG.LY’s editor we were able to hit key RFP requirements and deliver a template-based creative experience that now serves 1,000+ customers. It helped us win more deals and exceed enterprise expectations without needing to hire dedicated design teams.
Rob Driscoll
Director of PM, Optimizely
Since integrating IMG.LY’s editor, we now deliver 30,000+ ad creatives per month, dramatically shorten time-to-launch, and help our clients cut design spend by up to $10,000 per month.
Logan Welbaum

Embed an editor instead of building one
Paper.js lets you script vector graphics, but the interface people edit them in is left to you. With CE.SDK, you embed a ready-made embeddable editor, and IMG.LY maintains the engine, file formats, and rendering pipeline behind it.
