How do I resize an image or photo to a specific KB size (e.g. 20 KB or 50 KB)?

Upload your photo to UploadRight, set your target Min and Max KB (for example, 20 KB to 50 KB), and our client-side binary search quantization engine compresses the image to that exact file size without quality loss.

How do I resize photo dimensions in pixels (px) or centimeters (cm)?

UploadRight allows you to enter target width and height in pixels (px), centimeters (cm), millimeters (mm), or inches, while automatically maintaining or locking the exact aspect ratio.

Can I resize an image to both dimensions and KB size at the same time?

Yes! UploadRight simultaneously resizes your image to exact pixel dimensions and applies iterative binary-search JPEG quantization to hit your specified min-KB and max-KB limits with 200 DPI headers.

Are my images uploaded to the internet or any cloud server?

No. UploadRight operates 100% client-side in your web browser memory. Your images never leave your computer or smartphone.
