SellstampFree image tools
Convert between JPG, PNG, WebP, AVIF, SVG and ICO; compress, resize, crop, rotate and watermark; read or remove a photo’s hidden location data; pick colours; and make GIFs, collages and mockups. Each tool opens your image in this browser tab and saves the result back to your device, so there is no upload, no queue and nothing left on a server afterwards.
The trade-offs are stated on each page: which format keeps transparency, which quality setting stops being visible, what your browser can and cannot save, and where an in-browser model is softer than a large server-side one.
