Toolzy is a web-based platform that provides a collection of free online tools for working with PDFs, images, videos, and developer utilities. All tools operate entirely within the user’s browser, meaning no data is uploaded, processed, or stored on Toolzy’s servers. The sole exception is the File Sharing feature, which by design uses secure cloud storage to generate a shareable link for uploaded files. The platform requires no sign-up for most tools, though users can optionally create a free account to sync activity across devices and back up files. The toolset includes over 60 individual utilities. PDF tools allow users to merge, split, reorder, rotate, compress, password-protect, watermark, and extract text from PDF files, as well as convert PDF pages to image formats (JPG, PNG, WebP) and convert images into PDFs. Image tools support format conversion between JPG, PNG, WebP, GIF, SVG, BMP, and AVIF; multi-file compression with a quality slider and size preview; cropping and resizing with pixel or percentage precision; background removal; and color palette extraction. A photo editor provides layering, text, cropping, filtering, and background removal. An advanced video editor offers a multi-track timeline, transitions, effects, and color grading. Additional utilities include a screen and camera recorder, JSON utilities, and a file sharing service. Typical use cases include quick document manipulation without installing software, converting or compressing images for web use, editing videos in a browser, and sharing files via a temporary link. Because all processing happens client-side, users can handle sensitive documents without worrying about server storage. The platform is accessible at toolzy.cloud and includes a privacy policy and DMCA policy for transparency.
