Desktop Recorder

You are reading a PDF — a research paper, a contract, a study guide, a report — and you need to mark the important parts. Highlighting is the fastest way to do it. But unlike a Word document, PDFs are not designed for easy editing, and most tools that let you highlight them either require expensive software, a desktop installation, or a mandatory account signup.

You downloaded an API response, received a configuration file, or exported data from a web app — and now you have a .json file sitting on your desktop with no obvious way to read it. You are not alone. JSON is now the most widely used data format on the web, powering everything from REST APIs to app settings to database exports.

You have a low-resolution image — a blurry product photo, an old family picture, a small logo, or an anime illustration and you need it sharper, larger and print-ready. Traditional resizing just stretches pixels and makes things worse. AI image upscaling works differently and in 2026, the technology has reached a point where free online tools deliver results that were once only possible with expensive desktop software.

You took a photo on your iPhone, sent it to a friend on Windows, and they replied: "I can't open this." Welcome to the HEIC problem. Since iOS 11, Apple iPhones and iPads save photos as HEIC by default — a format that's smaller and higher quality than JPG, but that a huge amount of software still can't open. The fix is simple: convert HEIC to JPG, the format that works literally everywhere. This guide covers every method, on every device — Mac, Windows, iPhone, Android, Chromebook, and Google Drive — plus how to convert hundreds of files at once, and how to stop your iPhone making HEIC files in the first place. No paid software required. In a hurry? The fastest method that works on any device is a browser-based converter. Convert HEIC to JPG free here — no download, no signup, files auto-delete. The step-by-step OS methods are below if you'd rather use built-in tools.
