BUILT FOR USEFULNESS
Why SDS offers free tools
Small tasks add up. SDS tools are designed to remove friction from common jobs such as cleaning text, checking pricing math, preparing links, resizing images and planning simple business numbers.
PRIVACY-FIRST WHEN PRACTICAL
Most tools run in your browser
Text, calculations and image processing are handled locally whenever practical. Tool analytics record that a tool was viewed or used, not the text, passwords, images or numbers you enter.
