Questions?

Short answers about privacy, price and support.

¿Las herramientas son realmente gratuitas?

Sí. Todas las herramientas de ToolJiffy son completamente gratuitas, sin registro, sin marcas de agua y sin límites de uso.

¿Se suben mis archivos a algún servidor?

No. Todo se ejecuta localmente en tu navegador usando JavaScript y WebAssembly — tus archivos nunca abandonan tu dispositivo.

¿Las herramientas funcionan en el móvil?

Sí. Todas las herramientas funcionan en cualquier navegador moderno en escritorio, tablet y móvil — sin necesidad de instalar ninguna app.

¿Cumple ToolJiffy con el RGPD?

Sí. Al no transmitir ningún dato a servidores externos, ToolJiffy cumple plenamente con el RGPD europeo y la normativa española de protección de datos.

Privacidad total: procesamiento 100% en el navegador sin subir archivos

Cada vez que subes una imagen, factura en PDF, DNI o NIE escaneado a un sitio web de conversión online, tus datos privados atraviesan enrutadores públicos de internet y quedan almacenados en servidores de terceros. Muchos sitios de conversión recopilan tu dirección IP, leen el contenido de tus archivos y quedan expuestos a filtraciones de datos o incumplimiento del Reglamento General de Protección de Datos (RGPD).

ToolJiffy funciona con un enfoque radicalmente distinto: cada herramienta opera al 100% en el lado del cliente, dentro del entorno sandbox de tu navegador. Gracias a tecnologías modernas como WebAssembly, Web Audio API, renderización Canvas y Web Workers multihilo, tus archivos se procesan directamente en el hardware de tu dispositivo. Ni un solo byte se transmite por la red.

Desde la compresión de imágenes en formato WebP para eCommerce en Shopify o Mercado Libre, hasta la fusión de contratos de trabajo en PDF o el cálculo del IVA y retenciones del IRPF, ToolJiffy garantiza que tus datos no salgan nunca de tu ordenador, tablet o móvil.

Herramientas completas: Imagen, PDF, Calculadoras, Texto, Vídeo y Audio

Las Herramientas de Imagen incluyen compresor, convertidor HEIC-a-JPG, eliminador de fondo IA, redimensionador por lotes y generador de marcas de agua — todo en WebAssembly, con calidad profesional sin necesidad de servidor.

Las Herramientas PDF cubren fusión, división, compresión, OCR, conversión a Word/Excel y firma digital. Las Calculadoras abarcan hipoteca, IVA, IRPF, interés compuesto, IMC y propina. Las Herramientas de Texto incluyen contador de palabras, convertidor de mayúsculas/minúsculas (camelCase, snake_case), comparador de diferencias, previsualización Markdown y generador de códigos QR.

Las Herramientas de Vídeo y Audio gestionan compresión, recorte, cambio de velocidad, conversión de formato y grabación de voz — todo procesado localmente sin ninguna subida a la nube. Compatible con los principales navegadores en PC, Mac, Android e iOS.
