We built the image generator we couldn't find anywhere else
NPCGen started with a simple frustration: generating personalized images for outreach campaigns was either manual (slow, expensive) or required an engineer and a custom pipeline (weeks of work). We built the middle option — a tool anyone can use in an afternoon.
The problem with personalized image outreach
Cold email response rates have fallen sharply over the last decade as inboxes saturated and buyers learned to ignore generic messages. The data is consistent: personalized visuals in cold outreach increase reply rates by 2–3× compared to text-only emails. The problem is execution. Personalizing 5 images by hand is an afternoon. Personalizing 5,000 requires either a large design budget or writing custom code.
NPCGen exists to close that gap. Upload one image template, drop in a CSV with names, companies, or any variable data, and NPCGen renders a unique image for every row. The output is a ZIP of ready-to-use images — no code, no design software, no waiting.
The same workflow applies to event badges, personalized certificates, campaign creatives, and any situation where you need the same template filled with different data — at volume.
What we stand for
Speed over ceremony
A marketing team should be able to go from idea to 10,000 personalized images in under an hour. We build toward that benchmark.
Precision at scale
Every rendered image should be pixel-accurate to the template. Batch size of 10 or 100,000 — the output quality is the same.
Built for non-engineers
The visual template editor, CSV upload, and ZIP download require zero coding. Enterprise API is available for teams that want it.
Accessible pricing
The free plan gives 500 images/month — enough to test campaigns, run pilots, and validate ideas before scaling up.
NPCGen by the numbers
How NPCGen works under the hood
NPCGen is built on a distributed rendering pipeline with horizontal auto-scaling workers. When you submit a batch job, each row in your CSV is dispatched as an independent rendering task. Workers process rows in parallel — a 1,000-image batch takes roughly the same wall-clock time as a 100-image batch because the work is spread across multiple render nodes.
The visual template editor runs in the browser and stores zone configurations (position, font, size, color) as JSON. When a batch is submitted, the backend reconstructs each frame using the template image and the zone config, substituting CSV column values into the designated zones using Pillow.
Enterprise accounts get REST API access with webhook callbacks for async batch processing — enabling integration into CRM workflows, event management platforms, and marketing automation pipelines without any manual steps.
Who uses NPCGen
Sales and SDR teams use NPCGen to create personalized outreach images for cold email campaigns — one image per prospect, with their name, company, or a custom stat embedded in the visual. Teams running 500–5,000 touch campaigns per month are our most active users.
Event organizers use the platform to generate attendee badges, certificates, and credential cards from a spreadsheet. Upload the badge template, drop the attendee roster CSV, download 500 print-ready badge images in minutes.
Marketing agencies use NPCGen for clients running high-volume social campaigns — where each post needs a unique visual variant for different audience segments or product lines.
Growth and performance marketers use the API to integrate personalized image generation into automated outreach sequences, CRM triggers, and email flows without manual intervention.
