Gypes

Private local PDF tool

PDF merger

Combine PDF files in the order you choose, entirely in this browser, then download one merged document.

  1. Select at least two PDF files.

Combine PDFs without uploading them

Select between 2 and 20 PDF files. Use the up, down, and remove controls to set the document order, then merge and download the result. The browser reads the selected files and creates the combined PDF locally; Gypes does not intentionally receive their contents.

What is preserved

Visible pages, their dimensions, rotation, graphics, and embedded page resources are copied into the new file. The merger does not promise to preserve document-level bookmarks, portfolios, attachments, scripts, digital signatures, accessibility structure, or every interactive form behavior. Existing digital signatures will not validate as signatures of the newly created document.

Encrypted and very large PDFs

Password-protected or encrypted files are not supported. The page limits selection to 20 files and 100 MB total, but browser memory limits may be lower—especially on phones. The output can be similar in size to the inputs because merging is not compression.

Review the downloaded PDF before deleting originals or relying on it. Keep source documents and use an approved document workflow when retention, signatures, accessibility, evidentiary integrity, confidentiality, or regulatory compliance matters.
