Compress PDF

Reduce PDF size by rasterizing pages at your chosen quality. Nothing is uploaded.

Compression rasterizes each page, so selectable text, links, forms, and searchability are not preserved. If the result is larger, the original PDF is returned.

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.
