Image processing happens locally in your browser. Selected images are not uploaded to our server.
What stays on your device
When you select a folder or files, the browser reads those files in memory on your computer. Resize, preview, folder save, and ZIP creation all happen in this page. Image bytes, filenames, and output files are not sent to an application backend.
What this site loads
The site serves static HTML, CSS, and JavaScript from the same origin as this page, including the bundled resize and ZIP libraries. There is no account system in this version, and this version does not include advertising or analytics scripts.
Folder save
If you use Save to Folder, the browser asks you to pick a local directory and writes files there with your permission. That directory is on your computer, not on a remote disk.
ZIP download
If your browser cannot write to a folder, resized files are packed into resized-images.zip
in memory and downloaded through the browser’s normal download flow.
Metadata
Exported images are newly encoded. EXIF and similar metadata from the originals are not preserved.
