About Toolvore

Toolvore is 163 small utilities — converting a file, formatting some JSON, compressing a photo, working out a percentage. The kind of thing you need once, quickly, and then forget about until the next time.

Why the tools run in your browser

Most sites that convert a file ask you to upload it first. Your PDF goes to their server, gets converted there, and comes back. That is the easy way to build it, and it means a contract, a passport scan or a set of medical letters has been sitting on a stranger’s computer.

130 of these 163 tools never send anything anywhere. The conversion happens in the page itself, using the same technologies a browser already has — canvas for images, WebAssembly for formats a browser cannot read natively, the Web Crypto API for hashing. Your file is read into memory, worked on, and handed back. There is no upload because there is no server involved.

That figure used to read 131. We wrote a script that opens every one of those tools, uses it, and records every request that leaves this site — and it found that the text recogniser downloads its engine and language pack from a public code CDN the first time you run it. Your image is not part of that request and never has been, but “runs on your device” and “contacts nobody” are two different claims, and we had been making the second while only the first was true. The number is now the one we can defend, and the script is part of the check suite we run before shipping, so a new tool that quietly adds a third party shows up as a failure rather than as nothing at all.

How to check that for yourself

You do not have to believe any of the above, and you should not have to. Two ways to verify it in under a minute:

1. Open any tool once, then turn off your internet connection and reload the page. It keeps working. Software that needed a server could not.
2. Open your browser’s developer tools, switch to the Network tab, and use a tool. You will see no request carrying your file.

Where it is not true

15 tools genuinely need a server, because they look something up that only exists elsewhere — today’s exchange rate, a domain’s DNS records, the weather. A further 17 send the text you type to an AI provider, because that is what makes them work at all.

Every one of those pages says so on the page itself, before you type anything, and the privacy page lists each one by name along with exactly what it sends and to whom. We would rather lose the simplicity of “nothing ever leaves your device” than make a claim that is true of most of the site and quietly false on the rest.

What we do not do

• No accounts. Nothing here asks you to sign up, and nothing is gated behind doing so.
• No file storage. There is nowhere for a file to be stored, because none arrives.
• No selling data. The only personal thing we can hold is an email address, and only if you type one into the “tell me about new tools” box — see the privacy page. It is not sold, and nothing has ever been sent to it.
• No dark patterns around the result — no waiting timer, no “upgrade to download”, no watermark on the free version.

Honesty about the tools themselves

Some of these tools have real limits, and we would rather write them down than let you find out afterwards. Compressing a PDF by rasterising it turns the text into pictures, so you can no longer select or search it — that page says so before you press the button, and if the result comes out larger than what you started with, it tells you to keep your original. The background remover is built for photographs of people and is noticeably weaker on objects, which the page says rather than letting you spend the download finding out.

Where a tool cannot do something well, we prefer not to ship it. There is no PDF-to-Word converter here, despite it being one of the most searched-for tools of this kind, because a PDF stores letters at positions rather than paragraphs and tables — converting it means guessing at the structure, and every browser-based attempt produces a document that falls apart the moment you try to edit it.
