Small tools, done properly.
Velto started as a folder of scripts that kept getting rewritten: a grade calculator here, a binary decoder there. The web versions out there were buried under ads and pop-ups, so we built clean ones and made them free for everyone.
Today it is a growing collection of calculators, converters and generators, all free and instant. No accounts, no clutter, no surprises. Just the tool you came for, fast.
