Compress Image makes JPG, PNG and WebP photos smaller while you watch the result. Pick an output format and drag the quality slider — the preview and the new file size update instantly, so you can find the point where the image still looks good. If compression would make the file bigger, the tool keeps your original. Images are processed in your browser and never uploaded.
Open Compress Image
Launch Compress Image directly in your browser — there is nothing to download, install, or configure first.
Add your image
Drag and drop or select the image (or images) you want to work with. They load straight into Compress Image and are never uploaded.
Adjust and apply
Fine-tune the available settings and run Compress Image. Your images are processed entirely in the browser.
