What is pictkit?

PictKit is a free online toolbox with more than 27 image editing tools, and everything runs directly in your web browser instead of being uploaded to a server. Because the processing happens locally on your own device, you can even disconnect from the internet after the page loads and the tools will keep working, and the project points out that no files are stored or transmitted anywhere. The toolbox is organized into a few groups. Core tools cover compressing images, resizing them, cropping and rotating, converting between formats like JPEG, PNG, and WebP, and adding rounded corners or borders. A filters and adjustments section offers artistic effects such as sepia and grayscale, several kinds of blur, and detailed color adjustments like brightness, contrast, and saturation. An annotation group lets you add watermarks, draw arrows and shapes on an image, make memes, and compare two images side by side. A generation group can create QR codes, decode them, edit simple vector graphics, generate favicons in multiple sizes, build photo collages, add decorative photo frames, and split or merge images. Finally, a set of utility tools handles picking exact colors from an image, extracting a color palette, viewing camera metadata like GPS location, and stripping that metadata for privacy. The interface supports both English and Chinese throughout, with separate web addresses for each language, and includes a dark and light theme, keyboard shortcuts, and a global search across all the tools. It is built with React, TypeScript, and Vite, styled with Tailwind CSS, and uses libraries such as Framer Motion for animation and Radix UI for accessible interface components, alongside the browser's own Canvas and Web Worker features to do the actual image processing.
