Electro AI Lab PDF Editor: Fast PDF Tools in One Product
How Electro AI Lab built a premium PDF editor with merge, edit, split, compress, OCR, watermark, and page tools behind a NestJS API.
The challenge
Businesses and creators still bounce between fragmented PDF utilities — one site to merge, another to compress, another for OCR — often uploading sensitive files to unknown cloud services. That creates friction, privacy risk, and inconsistent results.
Our solution
Electro AI Lab launched the PDF Editor at pdfeditor.electrodigitalai.com as a single toolkit: upload a PDF, choose a focused tool, and process documents through a unified NestJS backend with pdf-lib pipelines, streamed uploads, and a responsive preview-first UI.
Our approach
We designed the product around a toolkit model rather than a bloated all-in-one canvas. Each capability — merge, edit, split, compress, rotate, delete/extract pages, OCR, watermark, organize, crop, page numbers, and view — is a clear entry point with shared upload, preview, and download flows.
Key features

Technologies used
Technical architecture
The browser handles upload, tool selection, and preview. Document processing runs on a NestJS API using pdf-lib pipelines for merge, split, edit, crop, watermark, organize, and related operations. OCR extraction supports readable text from PDFs and images. Streamed multipart uploads keep larger files workable while the frontend stays responsive.
Development process
- 1Upload a PDF or drag a file into the editor
