Linking vs. Embedding — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on May 5, 2024
Linking refers to creating a reference or a pointer to data stored externally, while embedding involves inserting data directly into a file, making it part of the file itself.

Key Differences
Linking connects a document to external data, allowing the document to fetch the latest updates from an external source each time it's accessed. On the other hand, embedding copies the data into the document at the time of insertion, making the document self-containing and static in terms of the embedded content.
When you link to data, such as in a spreadsheet linking to another file, changes made in the original source are automatically reflected in the linked file. Conversely, when data is embedded, such as an image in a Word document, the document retains the version of the data at the time of embedding, regardless of any changes made to the original source.
Linking is often used to reduce file size and maintain a single source of truth, as the linked data does not increase the size of the linking document. Embedding, however, increases the file size since it incorporates all embedded data directly into the file.
The reliability of linking depends on the availability of the linked source; if the source is moved or deleted, the link breaks. Embedding, however, makes the document more reliable in terms of data availability since the data is part of the document itself.
Security considerations also differ: linking can pose a security risk if the linked source is compromised, as it can spread malicious data across linked documents. Embedding is generally safer in this respect since the data is static and not susceptible to alterations in the source after embedding.

Embedding
In mathematics, an embedding (or imbedding) is one instance of some mathematical structure contained within another instance, such as a group that is a subgroup. When some object X is said to be embedded in another object Y, the embedding is given by some injective and structure-preserving map f : X → Y. The precise meaning of "structure-preserving" depends on the kind of mathematical structure of which X and Y are instances.

Common Curiosities
What are the main advantages of linking data?
Linking keeps file sizes small and ensures data reflects the most current information available from the source.
How does embedding enhance document preparation?
Embedding ensures all necessary data is contained within the document, enhancing portability and accessibility.
Can embedded data be updated automatically?
No, once data is embedded, it remains static and does not update if the original source changes.
What is the impact of linking on document performance?
Linking can slow down document performance if the linked data is complex or the external sources are slow to respond.
Does embedding affect the ability to edit data?
Embedded data can be edited within the host document, but such edits do not affect the original source data.
Can I convert linked data to embedded data?
Yes, most software allows you to convert linked data to embedded data, essentially copying the current state of the data into the document.
Is it safer to link or embed data in terms of security?
Embedding is generally considered safer because it does not depend on external sources, which might be compromised.
How do you ensure linked data remains secure?
To secure linked data, ensure the external sources are protected with adequate security measures, such as access controls and encryption.
What are typical use cases for embedding data?
Embedding is ideal for presentations, reports, or any documents that need to be fully functional offline or when shared across different platforms.
What happens when the source of a link is not available?
If the external source of a link is unavailable, the data will not be displayed, potentially breaking the functionality or completeness of the document.
How does linking affect collaboration on a document?
Linking can enhance collaboration by allowing multiple users to work with the most up-to-date data from a central source.
Can embedding increase the risk of copyright infringement?
Yes, embedding copyrighted material without permission can increase the risk of infringement, as the data is copied directly into new files.
Are there limitations on what data can be embedded in a document?
While most media types can be embedded, some software or platforms may have restrictions based on file size or format compatibility.
What types of files are commonly linked in documents?
Commonly linked files include databases, spreadsheets, and other documents that are frequently updated or maintained separately.
What tools are needed to link or embed data in a document?
Most word processors, spreadsheet programs, and presentation software support linking and embedding, with specific tools available in their interfaces.
