Why ToolBox?
Most βfreeβ online tools upload your files to a server, add watermarks or push you into a subscription after two uses. ToolBox works differently: each tool is a small web app that does the work on your own phone or computer using modern browser technology like Canvas, WebAssembly and on-device AI. That makes it private by default, free to run, and fast, because nothing has to upload first.
What you can do here
- Images: remove backgrounds with AI, crop for Reels and posts, compress and resize, pick colors.
- Video & audio: compress and trim videos, extract MP3 audio, turn clips into GIFs.
- YouTube & social: design thumbnails, generate tags and title ideas, download thumbnails, count captions and hashtags, make fancy bio fonts.
- Everyday: merge PDFs, turn photos into PDF, create QR codes for links, Wi-Fi and UPI, and convert text case.
Heavier engines, such as the video encoder and the background-removal model, load only when you press the button, so pages open quickly even on mobile data.
