help me build advance Base44 Web PDF Editor

@Herculesz

Hi Building a browser-based PDF editor in Base44 needs careful handling because text-based PDFs, form-filled PDFs, and scanned PDFs behave very differently. The main technical challenge is creating a reliable find-and-replace engine that supports case sensitivity, whole-word matching, and regex without breaking PDF layout or quality. I can build an embedded PDF editor with drag-and-drop upload, text/image overlay, annotations, highlighting, comments, merge, split, and clean export. For scanned PDFs, I’ll clearly separate OCR-based detection from normal selectable text handling so expectations stay accurate. From a technical side, I can work with JavaScript PDF libraries, PDF parsing/rendering, canvas-based editing, regex search logic, Base44 embedding, and client-side file processing. I’ll structure the code cleanly so your dev team can extend tools, APIs, and UI controls later. The editor will be browser-first, responsive, and optimized for large file handling as much as possible within client-side limits. My focus is a stable, embeddable PDF workflow with accurate search, safe editing, and smooth export. Thanks, Hercules

Getting a truly advanced PDF editor to run fast and flawlessly in any browser is a real headache, especially when you need regex-powered search and perfect text handling across every kind of PDF. Wrestling with clunky external binaries or slow tools wastes time and leaves you with unreliable results. With a custom Base44 web PDF editor, you can expect fast, accurate editing and searching for even your largest and most complex PDFs. Every feature from case-sensitive regex find and replace to merging, annotating, and exporting will be seamless and embedded anywhere you need. First, I will build the editor to handle uploads, smooth PDF rendering, and all your markup tools inside the browser. Next, I will ensure the search engine delivers precise, instant results across any PDF type. Finally, I will provide the clean Base44 source, a live demo, and clear setup notes for your dev team. Which PDF action is most urgent for you to see working first?
