Build a fully custom poster designer on any platform with our modern design editor SDK.
Trusted by 100+ industry leaders
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.

From a developer’s perspective, the most powerful feature of the photo editor is the integration process. It was completely flawless, quick, and easy to integrate.
Stefano Fornari
CTO, Funambol
We compared IMG.LY SDK with other solutions and found that it would be the best fit for us since it provides all the features that are crucial for our use case.

Built for platforms where poster design spans digital display and large-format print
Give users a starting point for every poster type
Templates scoped per poster type already handle the dimensions, proportions, and design zones, so users start with a structure that fits the format.
Keep designs crisp at any size
SVG shapes and graphic elements stay sharp from screen preview to A0 print. What users design at any size renders correctly at the final dimension.
Generate campaign and event variants without rebuilding designs
Connect templates to a data source and generate personalised variations at scale. Event series, tour dates, and promotional campaigns from one approved layout.
Key capabilities
For your users
See the poster in context before ordering.
Mockup previews show the design on a wall, in a venue, or in a real setting before the order is placed. Users who can visualise the finished poster make better design decisions and place more confident orders.
Design elements that stay sharp at any size.
SVG shapes, stickers, and graphics scale from the screen preview to the final large-format print without quality loss. What users see at design time reflects what arrives from the printer.
For your platform
Format-specific templates with exclusion zones.
Define safe zones, exclusion areas, and locked structural elements per poster format. Large-format production specs live in the template and apply automatically, independent of user behaviour.
Event and campaign variant generation at scale.
One approved template connects to a data source and generates every date, venue, and variant in a single batch run. Exclusion zones, bleed, and DPI validation apply per output without manual review.
DPI thresholds and large-format bleed configuration.
Set minimum DPI requirements and bleed margins appropriate for large-format output. Validation flags issues inside the editor before export, when correction costs nothing.
PDF/X export optimised for large-format production.
Production-safe exports with correct bleed, colour profile settings, and SVG rendering applied consistently across individual orders and batch-generated campaign variants.
How to integrate the poster editor
Four steps from embedding the editor to either large-format print or digital display.
Embed the editor
Start with CE.SDK and configure it for the poster formats you sell, from digital display to A0 print. For brand chrome or unusual workflows, the whole UI is customizable on the same creative engine.
Open Theming Demo
Templates across digital and large-format print
Design any number of poster templates with placeholder zones, locked structural elements, and format-specific dimensions configured per use case. Users start with a layout that already fits the destination, digital display, A3, A0, or any custom dimension, instead of a blank canvas.
Open Placeholder Demo
Personalize with variable data
Tag any element as a variable inside the template, date, venue, artist, price, offer code, and connect a structured data source. The headless API generates a unique poster for each record without a manual editor session per variant.
Open Variable Data Demo
Export for any format
Low-DPI raster zones get flagged before export. PDF/X heads to the press, PNG heads to the digital screen, both from the same template.
Open Validation Demo
One engine across web, mobile, and server
Users design on web and mobile. Platforms generate campaign batches server-side. IMG.LY runs one shared creative engine across all of these contexts, so templates, exclusion zones, bleed settings, and SVG rendering stay consistent from the design session to the production file.
Designs resume correctly on any device
A poster started on desktop opens identically on mobile. Layout, SVG elements, and template constraints are preserved across sessions and devices without manual reconciliation.
Large-format specs defined once, applied everywhere
Bleed margins, exclusion zones, and DPI requirements are set at the template level and applied to every output, interactive sessions and server-side batch generation alike.
Server-side generation for campaign and event variants
Generate personalised poster variants programmatically via the Node.js renderer. Event series, tour date posters, and promotional campaign variants produced at volume without a manual session per design.
How PostBuddy Launched Personalized Direct Mail for E-Commerce Without Building a Custom Editor

custom editor maintenance — embedded SDK instead
PostBuddy is a Denmark-based startup modernizing direct mail marketing — enabling e-commerce brands to create, personalize, and automate postcard campaigns integrated with their online workflows.
It’s hard to imagine we could have launched PostBuddy without a design editor SDK. Customers want an integrated experience, and we needed to channel our limited resources into our core mission, not a custom editor.
PostBuddy
Challenge
PostBuddy needed an embedded design editor that lets non-technical e-commerce users create print-ready postcards with personalization and variable data — without burning early-stage engineering on a custom editor.
Solution
Integrated CE.SDK to deliver an in-app design experience with mail merge, custom branding, and template guidance for streamlined postcard creation.
- 4× performance gap between A/B-tested designs proved design variation matters.
- Expanded reach into Sweden and Norway on top of the Danish home market.
- Engineering stayed focused on PostBuddy’s core direct-mail automation.
Why poster platforms trust IMG.LY
Built for the realities of large-format design
SVG rendering, exclusion zones, large-format bleed, and DPI validation are configured for the specific demands of poster and banner production, not adapted from a general-purpose design tool.
Templates that make scale manageable
Format-specific templates with correct dimensions and locked structural zones remove the decisions that cause errors at large-format output. Users design confidently within a structure that already fits the specification.
From a single poster to an entire event series
Variable data and server-side rendering turn one approved template into a complete run of event posters, tour dates, or campaign variants, each validated and export-ready, without manual work per output.
Consistent output at every stage of the workflow
The same engine renders the editor preview, the mockup, and the final exported file. What users approve on screen is what reaches the printer, at any size, on any platform.
More from IMG.LY
Poster platforms are judged by how well the finished product reflects what users designed
At poster scale, the gap between screen preview and physical output is where confidence breaks down. IMG.LY helps you close that gap with format-specific templates, SVG rendering, contextual mockups, print validation, and one engine across web, mobile, and server.
Poster FAQs
Any canvas size is supported, standard formats like A3, A2, A1, and A0, custom large-format dimensions, and digital display specifications. Canvas size, bleed, and exclusion zones are configured per template. The same SDK handles any format your fulfilment or display backend requires.
Shapes, stickers, and graphic elements are rendered as SVG, which is resolution-independent. They scale from the screen preview to any print dimension without pixelation or quality loss, and with minimal file size overhead. Raster image zones have configurable minimum DPI thresholds that are validated before export.
Exclusion zones are defined at the template level per poster format. Text safe areas, logo placement zones, and structural boundaries are locked and cannot be moved or edited by users. They apply automatically to every output generated from the template, including server-side batch variants.
Define which elements change per variant inside the template, date, venue, artist name, price, offer code. Connect a structured data source and the headless API produces a validated, export-ready file for each record. The batch runs without a manual editor session per poster, and every output inherits the exclusion zones, bleed settings, and DPI requirements of the original template.
Yes. Mockup previews contextualise the design in a real setting, on a wall, in a venue, or on a display surface, before the order is placed. Mockups update as users edit so the preview always reflects the current state of the design.
The SDK runs on web (React, Angular, Vue, Next.js, Svelte), iOS, Android, and server via Node.js. The same templates, large-format specs, and rendering behaviour apply across all of them.
