Where to start
The articles here are practical. Each one starts from a real job — sending a PDF that is too big for email, turning a scan into text you can edit, picking the right image format, reading a QR code someone sent you — and explains the steps and the settings that actually change the result. Most of those jobs map onto one of the tools below, so this page is also a quick guide to which one to open.
QR codes
Start with the guide to the free QR code generator: links, WiFi networks, WhatsApp chats and contact cards, adding a logo without breaking the scan, and how large to print a code so phones can read it. To read a code instead, the QR code scanner guide shows how to scan one from a screenshot, a PDF or your camera, and how to check where a link goes before you tap it.
PDFs
Compress PDF shrinks a file for email or an upload form (the file size limits for email and apps says how small it needs to be), Merge PDF and Split PDF combine or separate pages, and PDF to Word, PDF to Excel and PDF to JPG turn a document back into something you can edit or share as a picture. JPG to PDF goes the other way and collects photos or scans into one file. Sent an invoice that has not been paid? Here is what to do when a client does not pay.
Text in images and scans
Image to Text copies the words out of a photo or a screenshot, PDF OCR makes a scanned PDF searchable, and Image to Excel rebuilds a photographed table as a spreadsheet. A sharp, straight, evenly lit picture makes more difference to the result than any setting does. For the built-in ways on iPhone, Mac and Windows too, read how to copy text from an image.
Images and AI
Compress Image makes photos small enough for email and the web, PNG to JPG and the WebP Converter switch formats for apps and websites that insist on one, and Remove Background cuts out a subject or a logo. For the widths and KB targets a website needs, read how to make images load faster. To ask whether a picture was made by AI, the AI Image Detector gives an estimate with how sure it is — not proof — and says so when it cannot tell. If a detector has flagged your own photo, here is how to prove a photo is not AI generated.
