Private PDF processing in your browser

pixelsTools processes your files locally with browser APIs. Your PDFs and images are never uploaded to a server. Large documents use a Web Worker for document rebuilding where supported, with a compatible browser fallback.

What to expect

Encrypted or damaged PDFs show a clear error instead of crashing the page. Very large files use significant device memory, so a visible 100 MB per-file limit helps keep phones and laptops responsive.
