ImageToolKit is a small collection of free image tools built for one simple reason: most online image sites ask you to upload private photos to someone else's server, then put limits, watermarks or paywalls in the way.
We took a different approach. Every tool on this site runs entirely in your web browser using JavaScript — the open-source browser-image-compression, Tesseract.js and pdf-lib libraries do the actual work, plus the browser's own canvas. Your images are opened from your disk, processed in memory, and written straight back to your downloads folder. There is no server-side processing step at all.
The site is supported by advertising. We show ads so the tools can stay free — but ads never touch your images, because we never receive them.
Compression uses browser-image-compression (MIT licence). Text recognition uses Tesseract.js (Apache 2.0 licence). PDF creation uses pdf-lib (MIT licence). All are mature, widely used open-source projects.
