How KBKaro Works
Upload your image
Drag a file into the drop zone or choose one from your device.
Choose the required size or dimensions
Pick a quality mode, a target file size in KB, or new width and height.
KBKaro processes the image
Your browser decodes, resizes and re-encodes the image using its built-in image engine.
Preview the result
See the new file size, dimensions and a visual preview before you commit to anything.
Download it
Save the result straight to your device — there’s nothing further to do.
What “processed in your browser” actually means
When you compress or resize an image on KBKaro, your browser decodes the file, draws it to an in-memory canvas, applies the quality or dimension settings you chose, and re-encodes it as a new file — all using web platform features built into the browser itself. That output is what gets shown as a preview and offered for download. This approach is what lets the core tools run without an upload step or a processing server for basic compression and resizing.
We describe this precisely rather than in absolute marketing terms, because the exact technical guarantee matters for anything sensitive, like ID photos or signatures. If you want the full picture, including what a small number of standard web technologies (like basic page-load analytics) may see, read our Privacy Policy.
