Updated

To enable parallel downloading in Chrome, go to chrome://flags, search for Parallel downloading, set it to Enabled, and relaunch Chrome. The feature splits a large file into pieces and downloads them at the same time, which can speed up big downloads on a fast connection.

Before you start

  • Applies to: Google Chrome on Windows, Mac, Linux, ChromeOS, and Android.
  • You need: Nothing extra. This is an experimental Chrome flag.

What is parallel downloading?

Parallel downloading lets Chrome pull a single file over several connections at once instead of one. Chrome splits the file into pieces, downloads them at the same time, and reassembles them when they arrive. For large files on a fast connection, this can cut download time noticeably.

How do I enable parallel downloading in Chrome?

Warning: Chrome flags are experimental. They can change how the browser behaves and may be removed in a future update. Turn a flag off if you notice problems.

  1. Open a new tab and go to chrome://flags.
  2. Search for Parallel downloading, or go straight to chrome://flags/#enable-parallel-downloading.
  3. Set the drop-down to Enabled.
  4. Click Relaunch at the bottom of the page to restart Chrome.

Frequently asked questions

Does parallel downloading always make downloads faster?

No. It helps most with large files on fast connections. Small files, slow connections, or servers that limit connections may see little or no change.

Is it safe to enable this flag?

It is generally safe, but flags are experimental and unsupported. If downloads start failing, set the flag back to Default and relaunch Chrome.

What if the flag is missing?

Google occasionally removes or renames flags. If you cannot find it, search chrome://flags for downloading, and know that a future Chrome version may drop the option.

Parallel downloading is a simple flag that can speed up large downloads, and because it is experimental, you can turn it off just as easily if it ever causes trouble.
