I made a small tool for resizing and compressing images — entirely in your browser. It never uploads your files anywhere, so it’s private and works offline once loaded.
You can resize by percentage or set an exact pixel value for the longest or shortest side. You can choose the output format — JPG, PNG, WebP, or keep the original type. A slider lets you adjust compression quality, and the tool shows an estimated file size before you download.
It also works in batches. You can drop in up to 100 images, process them all at once, and download them individually or as a ZIP.
The main goal: make it quick to prepare images for the web without extra software.
