Image Tools

Image Tools brings together the everyday work people do to a picture before it's ready to use somewhere else — making it smaller, cropping it to size, converting it to a different format, fixing its orientation, or turning it into a favicon, a QR code, or a piece of ASCII art. Fifteen focused tools cover this ground today (a QR code scanner and an OCR text-extraction tool are planned for a follow-up addition, once the specific browser libraries they need are approved), each doing one image task well rather than trying to be a full photo-editing suite. Every tool here runs entirely in your browser, using the HTML5 Canvas API and other standard browser image APIs — nothing is uploaded to a server to be resized, compressed, cropped or converted. This matters more for images than for almost any other kind of file: a photo can carry far more personal or sensitive information than a block of text (a face, a location, a screenshot of something private), and this category is built so that none of that ever has to leave your device just to get a simple edit done. The trade-off is that everything is limited to what a browser can actually do locally — which, for the tasks covered here, turns out to be nearly everything most people need. The tools fall into a few natural groups. Everyday adjustments (Image Resizer, Image Compressor, Image Cropper, Image Flip & Rotate) cover the most common reasons to touch an image before using it elsewhere — fitting a size limit, reducing a file's weight, keeping only part of the frame, or fixing its orientation. Format and encoding tools (Image Format Converter, Image to Base64, Base64 to Image, Favicon Generator) move an image between representations: between file formats, into and out of the Base64 text encoding used in HTML and CSS, or into the multi-size ICO package a website favicon actually needs. Creative and generator tools (Placeholder Image Generator, QR Code Generator, ASCII Art Generator, Photo Editor) produce or transform an image for a specific purpose — a dummy image for a mockup, a scannable code for a URL or Wi-Fi network, a text-based ASCII rendering, or a brightness/contrast/filter pass over a photo. And two small creative applications — Online Whiteboard and SVG Editor — round out the category as lightweight, from-scratch drawing tools built directly on Canvas and SVG, each scoped deliberately as a core, useful subset rather than an attempt at a full professional design suite. SVG Optimizer sits alongside them, cleaning up hand-authored or exported SVG markup without needing a full external optimization library. A few of these tools — the Favicon Generator's ICO file format, the QR Code Generator's error-correction encoding, the ASCII Art Generator's bitmap font — are built entirely from scratch rather than relying on an external library, following the same approach used throughout this site's other tool categories: implementing a real, documented specification directly rather than pulling in a large dependency for a narrowly-scoped task. Each tool page explains exactly how it works, including any deliberate scope limits, so you know precisely what you're getting. If you're not sure which tool covers what you need, the search bar at the top of every page searches across all tool titles, descriptions and FAQs at once.
