Auto tries WebP and JPEG and keeps the smaller result. Transparent areas become white when exporting JPEG.

Use the Image Compressor form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
Example: open Image Compressor, enter a realistic set of inputs for your situation, and note the primary result. Change one input—such as an amount, rate, or option—and compare how the output changes so you can choose a scenario that fits your needs.
Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs in your browser—files are not uploaded to a server.
This tool runs in your browser for convenience. Results are estimates or transformations based on the inputs you provide and may not cover every edge case.
Light keeps higher quality and larger dimensions. Balanced is a middle ground. Strong uses lower quality and a smaller max dimension for the smallest files. Each level also tries lower qualities if needed to beat the original size.
