Tools that finish the job before your coffee cools
Four focused utilities for the admin side of freelance and small-business work. Each one runs entirely in your browser — your files are never uploaded to a server, because there is no server involved.
Invoice Generator
Fill in your details, add line items, set tax and payment terms, and download a print-ready PDF invoice. Works for USD, GBP, EUR, PKR and more. Nothing is uploaded — the PDF is generated inside your browser.
Open invoice generatorImage Compressor
Drop in up to 20 images, choose a quality level and output format, and compare the result side by side before you download. Compression happens on your own device, so private photos never leave your computer.
Open image compressorQR Code Generator
Turn a link, phone number, email address, Wi-Fi network or plain text into a scannable QR code. Pick your colours, set the error-correction level, then download a high-resolution PNG or a vector SVG for print.
Open qr code generatorAge Calculator
Enter a date of birth and get an exact age broken down into years, months and days, along with total weeks, days and hours lived, the weekday you were born on, and a countdown to the next birthday.

Most free online tools work the same way: you upload a file, a server somewhere processes it, and you download the result. That model is convenient for whoever runs the site, but it means your document sat on a machine you do not control, governed by a retention policy you did not read.
For the four jobs on this page, that round trip is unnecessary. Modern browsers can decode and re-encode images through the Canvas API, generate PDFs, draw QR matrices and do date arithmetic without any help from a server. So that is how we built them. When you compress a photo here, the pixels are read into your own machine’s memory, re-encoded there, and handed straight back to you as a download.
The practical consequences: an unsigned client contract or a photo of your passport never leaves your laptop, there is no file-size cap imposed by our bandwidth bill, and once the page has loaded you can keep working with no internet connection at all. The trade-off is that very large batches depend on your own device’s speed rather than a server farm’s — on a mid-range phone, twenty high-resolution images will take a few seconds longer than they would on a desktop.
