Processed on our server, kept nowhere — Merging, splitting, organizing, and building PDFs from images run on a ProntoUso server using a real PDF library, since reliable page-level editing isn't something every browser can do on its own. Each file is processed in memory only for that one request, the result is sent back, and nothing is written to disk or kept afterward.

Gộp & Tách PDF là gì?

A PDF toolkit with four modes: merge several PDFs into one, split one PDF into parts, reorder or rotate or remove pages, and turn images into a PDF.

TÌM HIỂU CÁCH HOẠT ĐỘNG CỦA CÔNG CỤ

How to merge, split, organize, and create PDFs from images

Merge

Add two or more PDF files, put them in the order you want using the move up and down controls, then merge. The combined file keeps every page from every source PDF, in that order.

Organize

Upload one PDF to see its pages listed in order. Move a page, rotate it in 90-degree steps, or remove it entirely, then save the result as a new PDF. The original file on your device is never modified.

Split

Enter which pages belong in each output file using a comma-separated list of pages and ranges, such as "1-3, 5, 8-10". Each group produces its own downloadable PDF.

Images to PDF

Add one or more JPG or PNG images, order them, and choose a page size: fit the page to each image's own dimensions, or use a standard A4 or Letter page with the image centered on it.

Limits to know about

  • Each operation uploads your file(s) to be processed and sends the result back, so very large or very long PDFs take longer, especially on a slow connection.
  • PDFs that need a password just to open them cannot currently be processed. A PDF locked only with an owner or permissions password, one that restricts printing or editing but needs no password to view, opens normally.
  • Turning PDF pages back into images is not part of this tool yet; merging, splitting, organizing, and creating PDFs from images are.

Page range example

Split a 10-page file

Enter 1-3, 5, 8-10 to create three output PDFs: pages 1 through 3, page 5, and pages 8 through 10.

1-3, 5, 8-10

Processed on our server, kept nowhere

Merging, splitting, organizing, and building PDFs from images run on a ProntoUso server using a real PDF library, since reliable page-level editing isn't something every browser can do on its own. Each file is processed in memory only for that one request, the result is sent back, and nothing is written to disk or kept afterward.

Các Câu Hỏi Thường Gặp (FAQ)

Are my PDFs uploaded to a server?

Yes. Merging, splitting, organizing, and creating PDFs all run on a ProntoUso server so the result is reliable across every page and file. Each file is processed in memory for that single request and is never stored or logged.

Can I merge password-protected PDFs?

Only if no password is needed to open them. A PDF locked with just an owner or permissions password still opens normally; one that requires a password to view it cannot currently be processed.

What happens if I enter a page range outside my PDF?

The split action rejects a page range that refers to a page your PDF does not have, and shows the valid page count so you can correct it.

Can I create a PDF from JPG and PNG images together?

Yes. Add any mix of JPG and PNG images in the Images to PDF tab; each becomes one page, in the order you arrange them.

Why is there no PDF-to-image conversion?

Turning PDF pages back into images requires rendering each page, which this version does not do yet. Merge, split, organize, and images-to-PDF cover the most common local PDF workflows today.
