One file or several — each is compressed on its own
Pages are redrawn as compressed images, so this works best on scanned pages or image-heavy PDFs. Text becomes part of the image and is no longer selectable, and already-small text-only PDFs may not shrink further.

PDF Merger is a free, browser-based utility that lets you merge, compress, and convert files — all without uploading anything to a server. Everything runs locally on your device, so your documents stay private.
“I got tired of jumping between five different websites just to merge a PDF, compress a Word doc, and squeeze down an image. So I built one place that does it all — merge PDFs, DOCXs, and images together, compress anything, and export to whatever format you need. No installs, no uploads, no fuss.”
Never. PDF Merger executes 100% locally inside your web browser using HTML5 Canvas, Web Workers, and WebAssembly memory buffers. Your documents, Word files, and photos never leave your device, ensuring complete confidentiality.
You can mix and combine PDFs (.pdf), modern Microsoft Word documents (.docx), legacy Word files (.doc), and images (JPEG, PNG, WEBP) in any order, and export the consolidated output as either a unified PDF or DOCX.
For PDFs, pages are rendered into optimized image streams and repackaged with targeted JPEG compression levels (Light, Standard, Strong). For standalone images, you have fine-grained control over visual quality and maximum dimension capping.
There are no daily quotas, paywalls, watermarks, or account registration requirements. Since all processing runs locally using your device's hardware, performance scales directly with your computer or phone's available memory.
PDF Merger was created by an independent developer to replace cluttered, subscription-locked file converters. The site is supported by non-intrusive Google AdSense advertising, allowing the tool to remain 100% free and open to everyone.
