Browser Storage Abuser


Have you ever wondered what is the limit of your browser's storage? This tool is for you to abuse and experiment that!

I've done a bit of research using this tool to summarize all modern browser's storage size. The result of the research is available on HTML5Rocks.

How to use

  1. Switch storage type under "Quota" between "Temporary" or "Persistent" if available (Chrome and Opera only).
    • Quota for "Temporary" is predefined depending on the remainig space of your disk.
    • You can assign arbitrary quota for "Persistent". Press "Request Quota" button after putting requested size.
  2. Choose from storage you wish to experiment with.
  3. Press "Fill Storage".
  4. Choose "Chunk Size" and "Quantity" and then press "Fill".

If quota is over for that storage, alert will pop up. That is the upper limit of the storage.

What is WebSQL?
  • Web SQL Database is a web page API for storing data in databases that can be queried using a variant of SQL. The API is supported by Google Chrome, Opera, Safari and the Android Browser. The W3C Web Applications Working Group ceased working on the specification in November 2010, citing a lack of independent implementations (i.e., the use of a database system other than SQLite as the backend) as the reason the specification could not move forward to become a W3C Recommendation. One potential alternative storage standard is IndexedDB.
