About Toolbench

Why this site exists

Most people, most weeks, need to do something small and slightly awkward to a file. Shrink a photo that is too large to email. Merge two PDFs before sending them. Read a block of JSON that arrived on one line. Generate a QR code for a poster.

The usual answer is to search, land on a site that asks you to upload the file to a server you know nothing about, wait, and then download the result — often watermarked, often behind a daily limit, and always with a copy of your file now sitting somewhere you cannot see.

Toolbench takes the opposite approach. Every tool here does its work inside your browser, on your own hardware.

What that changes

Your files are genuinely private. Not “deleted after an hour” — never received in the first place. You can verify this: open your browser’s developer tools, switch to the network tab, and process a file. No request carries it anywhere.

It is faster. A 40 MB photo is limited by your processor rather than your upload speed. On a slow connection the difference is not subtle.

There are no limits to enforce. Daily quotas and watermarks exist because processing files on someone else’s server costs them money per file. Ours costs nothing per use, so there is nothing to ration and nothing to gate behind a subscription.

It works offline. Once a page has loaded, the tool on it keeps working with your connection switched off entirely.

The trade-offs, honestly

Running in the browser is not free of cost. Very large files are bounded by the memory your browser has available, so a multi-gigabyte video is out of reach in a way it would not be on a server. Some formats need a sizeable code download the first time you use a particular tool. And anything requiring serious computation runs at the speed of your device, which on an old phone is slower than a data centre would be.

For the everyday tasks these tools cover, that trade is clearly worth it. Where it stops being worth it, we would rather not offer the tool than quietly start uploading your files.

How it stays free

The site is funded by advertising. That is the whole model: no accounts, no premium tier, no upsell at the point you need the result. Because the tools cost nothing to run, ad revenue alone is enough to keep them unrestricted for everyone.
