About NextTool

NextTool is a free collection of everyday file and developer utilities that run entirely inside your web browser. You can merge and split PDFs, compress and convert images, remove backgrounds with an on-device AI model, format JSON and SQL, generate passwords and QR codes, convert units and time zones, and dozens of other small jobs that normally require either desktop software or a website that wants your files on its servers.

The whole site is a static web app with no user accounts and nowhere to upload your files. When you open a tool, the code for that tool is downloaded to your browser and runs locally, the same way a spreadsheet runs on your laptop. The only things we keep about you are a message you choose to send us through the Contact form, and the payment record if you choose to support the site.

Most "free online converter" sites work by uploading your document to a server you know nothing about, processing it there, and holding the result behind a watermark, a daily limit or a subscription prompt. For a contract, a passport scan or an internal spreadsheet, that trade is a bad one.

Browsers became powerful enough to do this work themselves. NextTool exists to prove that point in practice: the same tasks, without an upload wait, without the file leaving your machine, and without asking for an email address first.

• Local first. If a feature cannot be built client-side, we would rather not ship it than start uploading your files.
• No dark patterns. No forced sign-ups, no fake progress bars, no "your download is ready, install this app" detours.
• Honest labelling. A tool is only listed once it works, and its page says what it cannot do as well as what it can.
• Ads never see your files. Advertising pays for the site, but ad networks never receive the files or text you work on, because those never leave your browser.

NextTool is an independent project, built and maintained in India. It is not affiliated with, endorsed by or sponsored by Adobe, Google, Microsoft, iLovePDF, SmallPDF or any other company whose file formats or products are mentioned on this site.

Editorial content, the tool guides, FAQs and how-to explanations you see across the site, is written by us for this site and is not syndicated from elsewhere.

Every guide on this site starts from a question people bring to one of the tools: why a CSV breaks in Excel, why a PDF will not shrink, why an iPhone photo will not open on Windows. Each one explains the decision behind the task and ends at the tool that does it.

• Checked against the tool. Any statement about what a tool here does, which formats it reads, what it keeps and what it drops, is checked against that tool's code. Where a check found a page claiming more than the tool did, the page was corrected, and in some cases the tool was fixed instead.
• Sources you can check. Where a guide rests on a specification or official documentation, such as an RFC, a W3C standard or a vendor's manual, it is listed under Further reading at the end of the guide.
• Dated honestly. Each guide shows the date it was published and, if it has been corrected or expanded since, the date of that update.
• Removed when it stops earning its place. Guides that drifted away from what the tools here do, or that depended on rules outside our control, have been taken down rather than left to go stale.

If you find a mistake in a guide, write to us. Corrections are made and dated.

Hosting, bandwidth and development time are paid for by advertising served through Google AdSense and by optional support payments. Advertisers have no influence over which tools we build, and no advertiser or ad network receives the files you process. Full detail is in our Privacy Policy and Cookie Policy.
