The MyToolsLab promise

Private by design — your data stays on your device

Each tool is a small program that downloads to your browser and does its work there. There’s no server waiting to receive what you type, paste or upload.

  • Processed locally

    Text, CSV files, images and invoices are handled in your browser’s memory and never uploaded.

  • No accounts

    Nothing to sign up for and no email address needed. Open a tool and use it.

  • No trackers

    No analytics scripts, advertising pixels or third-party cookies on any page.

Useful tools without handing over your data

Many free online tools ask you to upload a file or paste text into a form that is sent to someone else’s server. MyToolsLab works differently: every tool is built with standard web technologies that run inside your browser, so the data you work with is processed locally on your own computer or phone.

That makes the tools a good fit for everyday work that involves information you’d rather keep to yourself — a customer list you need to de-duplicate, a JSON response that contains internal IDs, an invoice with your bank details, or a new password. Once a page has loaded, most tools keep working even if your connection drops.

What you can do here

  • Create QR codes and UTM-tagged campaign links
  • Count words, convert text case and write Markdown
  • Format and validate JSON, or remove duplicate rows from a CSV
  • Generate strong passwords with secure randomness
  • Build a PDF invoice and work out VAT or percentages
  • Extract a colour palette from your own image
