Why these run in your browser
Almost every free image tool online works by uploading your files to a server, processing them there, and sending them back. That is slower, it puts your images on somebody else’s hardware, and it is why those tools cap file sizes and batch counts.
Modern browsers can do the same work locally with the Canvas API, so we did that instead. Nothing here needs an account, none of it stamps a watermark on your output, and the only limit is your own memory.
Open your network tab while you convert if you want to confirm that no file leaves the page.
