How to use “Split PDF by Pages & Ranges”

Split PDF by Pages & Ranges belongs to the PDF tools on KivTools. The workbench above handles the whole job on one screen: files chosen from your device, then a file you download.

The conversion runs inside the page with browser JavaScript. Nothing you enter is uploaded, the tool keeps working offline, and it is safe for data you are not allowed to send to a third party.

  1. Select the file to process with the file picker above.
  2. Press Process files to generate the result.
  3. Press Clear to reset the form before the next run.
  4. Check the result against a second source before you rely on it in production.

Background and accuracy

PDF tools

Binary formats carry more than the content you see: metadata, colour profiles, embedded fonts and, in practice, a fair amount of information you did not intend to publish. These tools transform or inspect a file while keeping the payload intact.

Two traps dominate: quality lost through repeated re-encoding, and metadata left in place after an edit. Compress once from the original, and inspect what the file still declares about you before sharing it.

Getting reliable results

Browsers, desktop tools and command-line utilities should agree on the result; a mismatch usually means a different encoding, locale or version. Open the result in a viewer you trust and check size, dimensions and, where it matters, the metadata panel rather than the file name.

Some formats are containers for other formats, so the extension alone does not tell you what is inside; when a system rejects a file, look at the actual header bytes before renaming it. Keep a copy of the input while you experiment, so a wrong setting never destroys the source.

Practical details

Input & output

Accepts a PDF file and a page-group expression like 1-3;4;5-7; outputs the selected PDF parts packaged in a ZIP archive.

Common uses

Splitting a long PDF into per-page files for review, extracting a custom set of non-contiguous pages, and packaging selected page ranges into a single ZIP.

Processing & privacy

The PDF file is processed in browser JavaScript; the input PDF is not uploaded to KivTools.

Limits & compatibility

The page-group parser requires the exact semicolon-separated syntax shown; malformed ranges can fail, and the browser's memory limits very large PDFs.

Frequently asked questions

Is Split PDF by Pages & Ranges free to use?

Yes. Every tool on KivTools is free, needs no account and has no usage quota. There is no paid tier hiding behind the workbench, and no email address is required to use the result.

Where is my data processed?

Inside your browser. The page loads a script once and the conversion happens on your machine, which is also why the tool still works when the network drops.

What can I feed into Split PDF by Pages & Ranges?

Accepts a PDF file and a page-group expression like 1-3;4;5-7; outputs the selected PDF parts packaged in a ZIP archive. Large inputs are usually handled without trouble, but extremely large ones are better processed in a local command-line tool.

How accurate is the result?

PDF is a container: fonts, images and metadata travel with the pages you see. Compare a small known-good sample first when the output feeds an automated pipeline.

Can I use the output commercially?

The output is yours: no watermark, no licence tag, no attribution requirement. Check the underlying format or library licence when the result ships in a product.

Does it work on mobile and offline?

The page works in any modern mobile browser, and the layout collapses to a single column on small screens. Local tools keep working offline once the page has loaded.
