tooldly.Free Online Tools 🔒 100% local — no uploads

About Tooldly

A small toolbox with a simple rule: your files should never have to leave your device just to get a small job done.

What is Tooldly?

Tooldly is a collection of free online tools for everyday tasks — converting subtitle files between SRT and VTT and fixing their timing, turning iPhone HEIC photos into JPG or PNG, viewing and removing photo metadata, generating QR codes and barcodes, counting words, and creating strong passwords. It also includes TabAnchor, a browser extension that saves and restores tab sessions.

Each tool does one job, does it in your browser, and gets out of the way. There are no accounts to create, no software to install, and no watermarks on your results.

Who makes it?

Tooldly is designed, built and maintained by a single independent developer — not a company, not a team, and not a data business. It started as a side project with a stubborn idea: most "online converter" websites upload your files to a server because that's how they've always done it, not because they need to. Modern browsers are powerful enough to do the work themselves, so Tooldly's tools do exactly that.

The local-first philosophy

Every Tooldly tool runs 100% locally, in your browser, on your device. That choice shapes everything:

  • Private by design. Your files are never uploaded, so they can't be stored, leaked, sold or scanned. Privacy here isn't a promise — it's a consequence of the architecture.
  • Instant results. Nothing travels across the internet, so there's no upload queue and no waiting on a busy server.
  • Works anywhere. Once a tool's page has loaded, the processing happens on your machine — even a flaky connection can't interrupt it.
  • Free, sustainably. Because your device does the computing, running Tooldly costs almost nothing — so the tools can stay free without harvesting your data.

If a job genuinely can't be done locally, Tooldly would rather not offer that tool than quietly start uploading your files.

What's here today

New tools are added slowly and carefully — each one has to earn its place and follow the same local-first rule.
