Duvora Tools is a free collection of 26 online tools built by Duvora Group, a team that makes websites and video ads for brands and creators. We built the tools we kept needing ourselves: caption and hashtag helpers, image resizers, and calculators for loans, investments and tax.
What we believe
- Tools should be free and instant. No sign-up, no paywall, no waiting.
- Your data stays with you. Every tool runs in your browser. We do not upload or store the text, images or numbers you enter.
- Numbers need explanations. Each calculator shows the formula it uses and a guide to reading the result.
How we keep the site free
The site is supported by advertising. Ads never change a tool's results, and we label our estimates clearly as estimates.
Accuracy
We check our formulas against standard financial references and official tax rules, and update them when rules change. Calculators give estimates for planning; for important financial decisions please confirm with your bank, lender or a qualified adviser. See our disclaimer, and read our editorial policy to learn how our guides are researched, written and corrected.
