All NexKit tools in one place

Choose a tool by the result you need

NexKit Tools brings together utilities built for everyday document, image and network tasks. Use it when you need a smaller attachment, a selected set of pages, a compatible image, or an explanation of a connection problem. The directory helps you choose; the linked product page runs the operation and explains its limits.

Documents and scans

Merge PDF combines several documents. Extract Pages makes a new file from a selection; splitting creates separate documents instead. Rotate and remove unwanted pages before combining scans. Try compression last, on a copy, and check readability: an already optimized PDF may not get smaller.

Images, formats and small utilities

Resize changes dimensions; compression aims to reduce bytes; format conversion changes compatibility. Choose JPG for photos or PNG when transparency matters, and keep the original. The image toolkit covers these tasks. Utilities cover tasks such as QR codes, JSON formatting and unit conversion.

Network checks and AI writing

DNS Lookup helps inspect a hostname’s records; it does not diagnose every cause of a failed connection. Start with the address or hostname you are checking. AI writing tools are a separate workflow: read their processing information before entering private text and verify the output.

Where processing happens

This hub has no file upload or processing form. PDF and image tools labeled “Runs in your browser” process selected files on your device. Loading their code, workers or models still requires network requests; site analytics is separate from file processing. Network and AI tools have different request and data boundaries. Check the individual page’s label, formats and limits before starting, and read the hub privacy policy.

Guides and tests to use before you start

The network-trace report recorded no file-upload requests for Merge PDF and PNG to JPG in its August 2026 desktop tests. That observation covers those fixtures, not every tool or future release. The page-limit test accepted 299 and 300 pages and rejected 301 in Add Page Numbers; it did not verify the exact byte-size boundary. These reports show both results and what remains untested.

For a scan, use the scan preparation checklist. For a large attachment, read why some PDFs will not compress further before repeating the same operation.
