Best for scanned documents and image-heavy PDFs. Each page is re-rendered at a lower quality and rebuilt into a lightweight PDF entirely in your browser. Note: this converts pages to images, so existing selectable text will no longer be copy-pasteable — for a PDF with real text you want to keep searchable, use our PDF OCR tool instead.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.

Frequently Asked Questions
Will my PDF text still be selectable afterward?+
No — compression works by re-rendering each page as an image at a lower quality, so any selectable text becomes part of that image. If you need to keep text selectable, use our PDF OCR tool instead after compressing, or compress less aggressively.
Which compression level should I choose?+
"Recommended" balances size and readability for most documents. Use "Extreme" only when the absolute smallest file size matters more than visual quality, like for email attachment limits.
Does this work for PDFs that are already mostly images?+
Yes — scanned documents and image-heavy PDFs see the biggest size reduction, since that's exactly the kind of content this tool re-compresses.
