PDFscaler

PDFscaler is a free toolkit for everyday PDF, image, and calculator tasks — merge, split, compress, convert, crop, watermark, and more — all running entirely in your browser. Unlike most PDF tools, nothing you upload ever touches a server. Every file is processed locally on your own device, so your documents stay private by default. Built for people who need a quick, no-signup way to handle PDFs without installing software or trusting a third-party server with sensitive files — resumes, forms, scanned documents, whatever you're working with. No account required. No file size games to unlock features. No watermarks added to your output.
