Create QR codes, merge PDF files and work out profit, margin, markup and discounts directly in your browser. No account needed, and the files and numbers you use stay on your device.
Create QR codes for websites, plain text, Wi-Fi logins, contact cards, email, phone calls and SMS. Change the size and colors, add a logo, then download PNG or SVG.
Combine two or more PDF files into one document. Add files, arrange them in the order you need and download a single merged PDF.
Work out net profit, profit margin, markup and break-even price including shipping, other costs and marketplace fees.
QR generation, PDF merging and every calculation run as JavaScript in your browser. We don't run an upload server, so there is nothing of yours for us to store.
Open a tool and use it. There are no logins, no email sign-ups and no limits on how many QR codes or merges you make.
QR codes are decoded automatically to confirm they scan back correctly, and the calculator page lists the exact formulas it uses.
