How files are handled

Logo Lab opens the files you choose only inside your browser tab. Images are not uploaded, sent to a server or stored by this site, and no AI service is called. Closing or reloading the page discards them.

Limits keep the page responsive: up to 5 MB for logos and 10 MB for other images, up to 4096 px per side. SVG files are treated as untrusted: scripts, event handlers, embedded pages and external references are removed, and the result is only shown as an image.

Embedding in articles: put a paragraph containing only [lab:palette], [lab:contrast], [lab:before-after] or [lab:editor] into an article and the matching tool appears in its place.
