Reduce an image file when re-encoding helps
Choose a supported quality output, compare the actual before-and-after byte counts, and keep the result only when it suits the job.
Open private workspace
Opens in this tab on the ad-free workspace at tooleni.com. No file detail is added to the link.
When this tool is a good fit
Use this for a supported still image that must be easier to attach or publish and can tolerate a reviewed re-encode.
- Prepare a working copy and keep your original file unchanged.
- Read the limits below before opening the private workspace.
- Review the generated result on your device before sharing or replacing anything.
What you receive
The result is one locally generated image in the chosen supported format, with a truthful size comparison and fixed output name.
The workspace is a separate, ad-free page designed for the document task. This information page never receives a selected file and does not run the processor.
How to prepare and finish
- Start with one supported JPG, PNG or WebP image and keep the original because compression may change visual detail.
- Open the private workspace, choose an available quality or clean re-encode option, and inspect the preview at useful zoom.
- Compare the measured local file sizes and download only when the new image is acceptable; a larger result is reported honestly.
What stays private
- Decoding and re-encoding happen inside the browser workspace, and EXIF, GPS, XMP, IPTC and comment metadata are not copied.
- The public page receives neither the image nor its before-and-after size, name, pixels or metadata.
