Questions
What is target image compression?
Target image compression means reducing an image toward a specific KB or MB limit for uploads, forms, or marketplaces.
Can it guarantee the exact file size?
No browser encoder can guarantee every exact byte target. The tool tries quality steps and reports whether the output is under the target.
Which format should I use for the smallest result?
For photos, JPG or WebP usually gets smaller than PNG. For screenshots with sharp text, test WebP first and compare the preview.
Does Compress Image to Size upload my file?
No. The image is decoded and exported locally in your browser tab.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
