Web tools platform
Practical browser-based tools for documents, images, files, and network diagnostics.
NexKit is an independent web tools and research project for people preparing documents, working with images, or investigating a connection problem. It combines focused utilities with practical guides and published tests of how those utilities behave.
Rotate sideways pages, remove blank pages, then check the remaining page order before merging attachments. Compress a copy last, and inspect small text and signatures before sending. Keep the original: compression may produce little improvement on an already optimized PDF.
Scan cleanup checklist →Extract selected pages when a recipient needs a short section; split when you need several separate documents; remove pages when you want one document with unwanted pages omitted. These operations change document structure, so check the output rather than assuming bookmarks or forms survive.
Compare split, extract and remove →Use JPG for photographs when a smaller attachment matters, PNG when transparency or sharp graphics matter, and WebP when the recipient accepts it. Converting formats cannot restore detail already lost. Preview the result before replacing the source.
Choose an image format →PDF and image workflows labeled “Runs in your browser” read selected files on your device and create a result to download. This is different from loading scripts, fonts, models or analytics over the network. Browser memory and the tool’s format and file limits still apply. Network diagnostics query addresses and hostnames; AI services have their own processing rules. Check the specific tool before entering sensitive information.

Short, task-focused reading for preparing, checking, and sharing everyday files.
The August 2026 test traced Merge PDF and PNG to JPG using synthetic files; neither produced a file-upload request. Compress PDF was tested separately.
Shows how to check a local-processing claim, with the limits of a desktop browser snapshot made explicit.

Useful when a scan needs to be clear and ready for a colleague, client, or portal.
Read article →Synthetic text, image-heavy and pre-optimized PDFs often stayed the same size. The report identifies one small reduction that did not reproduce.
Explains why compression is content-dependent and why an unchanged result should not be presented as a saving.
