PDF Merger
Combine all selected PDFs into one document.
Merge, split, convert, organize and optimize documents with simple tools that work right in your browser.

Select PDF files or images once, then use the tools below. The merger uses all selected PDFs; most other tools use the first PDF.

For best results, use a modern browser and keep a copy of your original documents. Large PDFs and high-resolution conversions may use significant device memory.
Compression options that rebuild pages as JPEG images can reduce file size, but make page text non-selectable and remove interactive elements, links, forms and accessibility structure. Choose “Preserve text and vectors” to retain document content structure; that option may not reduce file size. JPG/PNG conversion and image-based compression can use substantial memory for large documents. Password-protected or malformed PDFs may not work. Always review the result and keep your original.
Select PDF files from your device and choose an operation. Most PDF tasks run in your browser using client-side libraries. PDF-to-image conversion and image-based compression can take longer for large documents.
The PDF tools are designed for browser-side processing. The page loads third-party PDF libraries from public CDNs, but selected document contents are processed locally by the browser.
Some PDFs are already optimized or contain mostly text and vector graphics. Image-based compression can also increase size and converts page content into images, which removes selectable text.
Yes, on modern mobile browsers, although large files may need more memory and processing time. For best results, use a current browser and keep the page open until processing finishes.
