About Herramientas Web
A place to get everyday jobs with files and numbers done, with no red tape and without your data ever leaving your device.
What it is
Herramientas Web is a collection of free utilities: merge and compress PDFs, shrink images, count words, calculate percentages, convert formats, and many more. It is built for anyone who needs to get something done quickly from a phone or a computer, without installing software.
How we work
- Everything happens in your browser. The files and text you use in the tools are processed on your device. We never upload them to any server.
- No sign-up and no limits. We don't ask for an account, and there are no artificial waits or daily quotas.
- Plain, accessible design. Clear interfaces with full keyboard support, visible focus, and dark mode.
- Fast. Each page loads only what it needs. Heavy libraries are downloaded only when you use the tool that requires them.
- A focus on Argentina and Spain. Besides the general-purpose tools, the Spanish version of the site adds local utilities: VAT, aguinaldo (the statutory bonus), the dollar exchange rate, public holidays, and CUIT tax IDs for Argentina; and VAT, pesetas to euros, the minimum wage, IBAN, the DNI check letter, and the working calendar for Spain.
How it is funded
All the tools are free and will stay that way. The site is supported by non-intrusive advertising: fixed, clearly labeled spaces, with no pop-ups, no ads that cover the content, and no autoplaying video or sound. You can read more in the privacy policy.
