Descarga vs. bajada
In the context of computing, both descarga and bajada can be translated as download. However, they are not always interchangeable, as descarga is the standard and technical term, while bajada is more colloquial and informal.
Descarga
A2This is the most common, standard, and technical term for a download. It is the direct equivalent of the English noun and is used universally in software interfaces, technical documentation, and formal contexts. It derives from the verb descargar (to unload, to discharge), which perfectly fits the technical concept of transferring data from a remote server to a local device.

Bajada
B1This is a more colloquial and informal term for download. It comes from the verb bajar (to bring down, to lower), which evokes the idea of bringing a file down from the internet. While widely understood, it is less formal than descarga and is typically used in everyday conversation, not in technical manuals or on official software buttons. It is often paired with subida (upload, from subir - to bring up).

Summary
In summary, descarga is the universally accepted, formal, and technical term for a download. It is the word you will find on websites, in software, and in technical documentation. Bajada is an informal, colloquial alternative derived from the verb bajar (to bring down). It is commonly used in everyday speech among friends but is generally avoided in formal or technical contexts. For any official or professional purpose, descarga is the correct and safe choice.
