Split one PDF into several files
Extract only the pages you need or split the whole document into manageable parts, without sending the PDF to any service.
What it does
Select pages with the thumbnails, use Shift for ranges or type expressions such as 1-3, 5, 8-10. The tool can produce one PDF with the selection, one file per block of consecutive pages or one file per page.
Pages are copied from the original, so the content is not recompressed and text is never turned into an image.
How to use it
- Open Split PDF.
- Add the document you want to separate.
- Select pages with the thumbnails or type the ranges in the pages field.
- Choose the output: one PDF with the selection, several blocks or one file per page.
- Press the split button and download the result.
Why ConvUp
Precise selection
Thumbnails, ranges and shortcuts to pick exactly what you need.
Several outputs
One file, several blocks or one page per document.
Private by design
The PDF is not sent to any server during the process.
Split by pages, by ranges or by size
The page field accepts the notation printers use: 1-3, 5, 8- means pages 1 to 3, page 5 and page 8 to the end. If you prefer clicking, thumbnails support Shift for a whole range. “One file per page” gives you a PDF per page; “blocks” divides the document into equal parts.
Splitting does not recompress: every page is copied with its original content, so the parts weigh roughly as much as the whole file. If your goal is to fit an email limit, split first and compress afterwards — but do not expect splitting alone to shrink anything.
Frequently asked questions
Can I extract a single page?
Yes. Select that page in the thumbnails or type its number and choose the single-PDF output.
What does 1-3, 5, 8-10 mean?
It is a page range: pages 1 to 3, page 5 and pages 8 to 10. You can also use 8- to reach the last page.
Does splitting keep quality?
Yes. Pages are copied without rasterizing, so text and images keep their resolution.
Can I split a protected PDF?
Not if it is encrypted with a password. Remove the protection with the app that created it and try again.
