    How to use this tool

    Supported input and limits

    Frequently asked questions

    Will resizing improve low-resolution detail?

    No. Enlarging only resamples existing pixels; it does not recover missing detail.

    Are my files uploaded?

    No. A local browser worker processes your files. Names and contents are not stored or uploaded.

    How long are download links kept?

    Generated Blob URLs remain on this page until you clear or leave it. Save outputs before navigating away; the site has no server-side copy.
