Merge PDF

Combine PDF files into a single document. No account required. Processing stays in your browser.

How it works

Choose your file, adjust the options and generate a copy. Processing happens on this device. Keep the original and inspect the output before sharing.

Are my documents uploaded to a server?

No. Libraries are served from this website and processing happens in your browser. Reloading discards work you have not downloaded.

What are the limits?

Hasta 300 páginas en total; separar y comprimir admiten hasta 100. La memoria disponible depende del dispositivo. Esta herramienta no incluye OCR, firma con certificado, edición de texto existente ni conversión fiel de archivos DOC antiguos.

Get a useful result

Arrange documents in reading order before processing. For an application, for example, put the form first and its attachments afterwards. Check the first and last page of each document in the merged copy.

A practical example

Merge a two-page PDF with a one-page PDF: the result should have three pages in that order. Check the file list before processing.

Does merging also reduce file size?

Merging is not compression. Merge and inspect the document first; then use the compressor if you need a smaller file. Encrypted PDFs, interactive forms and digital signatures are not supported in this workflow.
