Choose a ToolAbout the PDF Tools
NKable PDF tools are a free set of browser-based utilities for everyday PDF work: combine several files into one, pull out page ranges, shrink oversized documents, add or remove a password, edit metadata, and convert between PDF and Word, Excel, HTML, EPUB or Markdown.
The NKable PDF tools cover the jobs that come up whenever a document has to be sent, filed or signed: merging a scanned contract into a single file, splitting a 200-page report into chapters, compressing an attachment under a mail-server limit, or converting a PDF into something editable.
Every tool is free with no account, no watermark and no page cap. Files are handled for the length of the conversion and then discarded — nothing is kept, indexed or shared, and there is no upsell to a paid tier hiding behind a page limit.
Pick a task below. If you are unsure which tool you need, the split tool extracts pages from one PDF, merge combines several into one, and compress reduces file size without changing the page count.
How to use the PDF Tools
- Choose a tool. Pick the PDF task you need from the list — merge, split, compress, protect, unlock or convert.
- Add your file. Drag a PDF onto the drop zone or browse for it. Most tools accept several files at once.
- Set the options. Choose page ranges, compression level, password or output format depending on the tool.
- Download the result. Run the tool and save the finished file. Multi-file output arrives as a ZIP.

Frequently asked questions
Are the NKable PDF tools free?
Yes. Every PDF tool is free with no account, no watermark and no page limit. There is no paid tier and no trial that expires.
Is there a file size limit?
Large files work, but very big documents take longer and depend on your connection. If a file over roughly 100 MB stalls, split it first and process the parts.
Do you keep my PDF files?
No. Files are used for the conversion and then discarded. Nothing is stored, indexed, shared or used for training.
Do these tools work on a phone?
Yes. Every tool works in a mobile browser on iOS and Android. Picking a file uses your usual file or photo picker.
Which PDF versions are supported?
PDF 1.4 through 2.0, which covers anything produced in the last twenty years by Word, Google Docs, InDesign, Acrobat and most scanners.
