Open toolFree image and PDF tools that respect your privacy
PixelResize is a complete toolkit for everyday image and PDF work, and every tool is free with no account, no watermark and no daily limits. Compress JPG, PNG and WebP photos to a smaller file size, convert between formats including HEIC to JPG and PNG to WebP, resize images to exact pixel dimensions, and crop, rotate, flip or watermark them in seconds.
Beyond images, the same workbench handles PDFs: merge several files into one, split a document into separate pages, compress a heavy PDF so it is easy to email, convert images to PDF or PDF pages back to images, and edit a PDF directly in your browser. There is even an AI background remover and a Smart Document Assistant that reads your file and recommends the right tool.
What sets PixelResize apart is where the work happens. Unlike most online converters that upload your files to a remote server, every operation here runs locally using the browser's Canvas and WebAssembly APIs. Your photos and documents never leave your device, are never stored, and disappear the moment you close the tab — which also means results are instant, with no upload or download round-trip, and the tools keep working even offline once the page has loaded.
