About NexTool
A local-first toolbox
NexTool is a website of browser tools at nextool.org. The point of the site is ordinary file work that people are often pushed to upload: merging a report with its appendix, splitting a packet, compressing a scan, comparing two Word drafts, exporting a spreadsheet, or shrinking an image. The tools run in the browser you already have open. For those jobs, the file is not posted to a NexTool server. There is no account to create and no folder of your documents waiting on the site. When you close the tab, the page forgets the file. That is intentional.
Privacy-first, on this site, means the default path does not take the file. It does not mean the page is a vault, and it does not mean third parties never exist. Google may set cookies when ads are enabled, which the privacy policy explains together with the opt-out links. Optional AI features send the request you start to an address you configure, and the key stays in the browser. Those features are labeled. They are not how PDF merge works. The guide that compares local tools with upload sites is the longer version of this idea, with the cases where a local tool is the wrong choice anyway.
What the site will not pretend
NexTool does not claim to be a law firm, a print shop, or a certified archive. A redacted PDF still has to be checked by you. A compressed scan can look worse. A Word-to-PDF export can be a picture. The pages say so because a tool that hides its limits is not private, it is careless. Educational labs that are still unfinished are not offered as working simulators on the public site. Small utilities that are not ready to carry a full guide are kept out of the index until they are. The tools that are linked from the homepage are the ones you can open.
The site is operated independently. There is no storefront staff and no telephone desk that receives files. The contact address for the site, for a broken tool, and for advertising is ads@nextool.org. Contact says what a useful message includes. Terms describe the lack of warranty that comes with a browser tool. Guides are short practical essays linked from the tools they describe. If you are writing about a bug, name the page, the browser, and what you expected. Do not attach the confidential file.
What you can verify yourself
You do not have to take the local-first sentence on trust alone. Open a tool, disconnect the network if you want, and process the public sample. The sample files are ordinary documents shipped with the site, not your files. A merge of the two-page report and the one-page appendix should come back as three pages in that order. A split of the three-page packet should come back as three PDFs in a ZIP. If a job instead asks you to sign in, or the download never appears and a server progress bar does, you are not looking at the tool this page describes. Optional AI is the exception that is labeled in the tool that uses it: the request goes to the address you typed, and the key stays in the browser. File jobs such as merge do not use that path.
