Tools that just work
A growing kit of small, single-purpose utilities for images, PDFs, text, code and more. Each does one job, runs entirely in your browser, and never sends your files anywhere.
Free online tools that run entirely in your browser
Tools That Just Work is a growing collection of free utilities for everyday digital tasks — converting images, editing PDFs, generating codes, formatting data, running quick calculations and more. There is no sign-up, no upload and no watermark. Every tool runs locally in your browser, so your files and text never leave your device and never touch a server.
Why browser-based tools?
Most "free" online tools upload your files to a server to process them. That is slower, and it means handing your documents, photos and data to a company you may not know. Our tools do the work on your own computer using modern web technology, so they are fast, private by default, and keep working even if your connection drops. Nothing is stored, logged or sold.
What you can do here
- Image tools — resize, compress, crop, convert between JPG, PNG, WebP and HEIC, add watermarks and inspect image details.
- PDF tools — merge, split, compress and sign PDFs, add page numbers, convert to and from images, and redact sensitive text.
- Finance & calculators — a full mortgage calculator, loan and compound-interest tools, invoicing, percentages, tips and unit conversion.
- Text & code — word counting, case conversion, JSON and SQL formatting, Base64, hashing, regex testing and UUIDs.
- Generators — QR codes, barcodes, strong passwords, favicons, colour palettes and CSS gradients.
