Why use this tool?
Many websites and forms require images under specific dimensions or file sizes.
Resizing before upload can make images easier to share, email or publish online.
This browser-first approach is useful for simple dimension changes without installing extra software.
How local processing works
The image is resized on a browser canvas and exported as a fresh file. The maximum side setting keeps the original aspect ratio.
The website still loads from PrivateConverts, but the selected file is handled by browser APIs on your device for this supported tool. In Developer Tools, local previews and downloads can appear as blob URLs; those are temporary browser objects, not server uploads.
Before converting private files
If a file contains personal photos, screenshots, client previews, location data or private notes, check whether the converter needs an upload. For this supported PrivateConverts tool, processing is designed to happen locally in your browser.
