Browser-local PDF workspace

Merge, reorder, or split PDF pages

No upload

Choose files to begin. PDF processing starts only after you press a create button.

Combine files

Merge PDFs

Select 2 to 12 PDFs, arrange their order, and download one combined document.

No merge files selected.

Select pages

Extract or reorder pages

Choose one PDF, enter the output order, then create one PDF or a ZIP of individual pages.

No split file selected.

The entered order becomes the output order. Use 3,1,2 or a descending range such as 8-5. Duplicate pages are included once.

Files stay on your device for supported local converters. The selected PDFs are read by client-side JavaScript and are not uploaded by this tool.

Document-level features can change. Interactive forms, signatures, bookmarks, attachments, and encryption may not survive page copying. Keep the originals.

What this PDF workspace supports

Merge copies every page from the selected PDFs into a new document in the displayed order. Extract or reorder copies selected pages into one new PDF in the sequence you enter. ZIP export creates one single-page PDF per selected source page.

PDF and ZIP processing code is loaded only when you use the workspace. Files stay in the current browser tab and the generated download is created on your device.

This version intentionally does not claim lossless compression, OCR, signature preservation, form repair, password removal, or file conversion. Those operations need separate quality and security boundaries.

Verify important documents

  • Keep every original PDF.
  • Open the downloaded result before sharing it.
  • Check page order, orientation, forms, and signatures.
  • Avoid editing a digitally signed original when signature validity matters.

FAQ

Are my PDF files uploaded?

No upload needed for browser-local tools. Files stay on your device for supported local converters. This PDF workspace reads and creates documents with client-side JavaScript.

Can I merge PDFs in a specific order?

Yes. After selecting 2 to 12 PDFs, use the Up and Down controls to set the order before creating the merged document.

How do I split or extract PDF pages?

Choose one PDF and enter pages or ranges such as 3,1,2 or 8-5. The tool creates one new PDF in the entered order, or a ZIP containing one PDF per selected page.

Can I change the page order?

Yes. The entered page sequence becomes the output sequence. Use individual pages, ascending ranges, or descending ranges to create the order you need.

Will signatures, forms, bookmarks, and attachments be preserved?

Do not rely on it. Page copying can change or remove document-level features, interactive forms, signatures, bookmarks, attachments, and encryption. Keep the original files and verify important outputs.

Why is there a 100 MB limit?

PDF processing uses browser memory. The limit reduces the risk of an unresponsive tab on devices with less available memory.
