Chrome and Edge Introduce Smarter Clipboard Handling With “Selective Format Read”
Google Chrome and Microsoft Edge have introduced a new clipboard optimization called Selective format read, designed to improve the speed and efficiency of pasting content into web applications. The feature is now enabled by default in version 149 of both browsers and works automatically without requiring changes from website developers.
A More Efficient Way to Read the Clipboard
Previously, when users pasted content into a website, browsers retrieved every data format stored in the clipboard. This could include:
- Plain text
- HTML formatting
- Images
- Rich text
- Other clipboard metadata
Even if a web application only needed plain text, the browser would still load all available formats, resulting in unnecessary processing and increased memory usage.
Only the Data That’s Needed
With Selective format read, browsers now take a more efficient approach.
Instead of loading every available format, the browser first checks which data types are present in the clipboard. The web application can then request only the specific format it needs—for example, plain text instead of HTML or image data.
This reduces the amount of information processed during paste operations, helping improve performance while lowering unnecessary memory consumption.
Benefits for Users
Although the change happens behind the scenes, users may notice:
- Faster paste operations
- Reduced memory usage
- Improved responsiveness in web applications
- More efficient handling of large or complex clipboard contents
The optimization is particularly beneficial when copying rich content from documents, websites, or applications that place multiple data formats onto the clipboard simultaneously.
Available Now
Selective format read is already available in Chrome 149 and Microsoft Edge 149, where it is enabled by default.
Because the feature is implemented directly within the browser, compatible websites benefit automatically without requiring updates or modifications from developers.
