I need a straightforward, browser-based PDF editor that mirrors the simplicity of DocFly but remains lean enough to run on low-cost hosting. The goal is to let a user open a PDF in the browser, make quick changes, then download the updated file—no bloated feature set, just smooth, reliable core editing. Here’s what I’m after: • A single-page web interface (vanilla JS or a lightweight framework is fine) that loads quickly and feels intuitive on both desktop and mobile browsers. • Client-side handling where possible—leveraging libraries like PDF.js—so server load and hosting costs stay minimal. • Basic edit actions: overwrite existing text, insert new text boxes, reposition elements, and save changes to a fresh PDF. • Clean code, clear comments, and a concise deployment guide so I can drop the project onto shared hosting and be live in minutes. Deliverables 1. Working web editor (source + minified build). 2. Brief README covering setup, config options, and any third-party libraries used. 3. A short video or screenshots demonstrating the edit-save flow. I’m after something fast, dependable, and easy to maintain—no enterprise bells and whistles, just the essentials done well. If you’ve built with PDF.js or similar tools before and can keep the footprint small, let’s talk.
