Comparison
CTXbase vs basic conversion tools.
Many converters stop at a download. CTXbase is designed to make the Markdown useful after that first conversion.
| What matters | CTXbase | Basic converter |
|---|---|---|
| Main outcome | Clean Markdown you can copy, download, save, or share securely. | A converted file for one-time download. |
| After conversion | The result can become a library item or a read-only access link. | Usually leaves you to manage the result elsewhere. |
| AI workflow | Designed for content you want to reuse in chats, prompts, and knowledge bases. | Often requires repeated uploads or manual copy-paste. |
| Page experience | The converter appears first, with clear details below for people who want to understand the product. | Often gives little guidance after the file picker. |

¿CTXbase es gratis? ¿Necesito una cuenta?
Convertir es gratis y los archivos de hasta 10 MB no necesitan cuenta. Sube un archivo, pega el enlace de una página web o pega texto, y copia o descarga el Markdown. Inicia sesión con Google para convertir archivos de hasta 100 MB, guardar resultados en tu biblioteca o crear enlaces de solo lectura.
¿Qué archivos puedo convertir y de qué tamaño?
PDF (incluidos PDF escaneados, con OCR), DOCX, PPTX, XLSX, ODT, ODP, ODS, RTF, CSV, JSON, XML, HTML, TXT y Markdown, un archivo cada vez. Los PDF y PPTX pueden pesar hasta 10 MB sin cuenta o 100 MB con la sesión iniciada; los archivos escaneados que necesitan OCR completo tienen un límite de 25 MB. Los demás formatos, hasta 4 MB. También puedes convertir una página web por URL o pegar texto directamente.
¿Qué puede leer una herramienta de IA a través de un enlace de CTXbase?
Los enlaces son de solo lectura. Un enlace de documento da acceso a un único documento Markdown guardado. Un enlace de biblioteca da acceso a tus 10 documentos guardados actualizados más recientemente, incluidos los que guardes después. Los clientes de IA conectados por MCP pueden listar y leer esos documentos, pero no pueden cambiar nada.
