Free Flash Detector

What this flash detector checks

Looks for Flash objects, embeds and loader scripts such as SWFObject.

The flash detector searches the page and its linked assets for object and embed tags pointing at .swf files and for Flash player scripts. Flash ended in major browsers at the end of 2020, so any hit is content visitors cannot see.

Why use a flash detector

Flash was shut down in 2020 and no current browser runs it. Pages that still use it show blank gaps or warnings, and search engines cannot read the content inside it.

Owners of older tourism, restaurant or property sites with animated headers or galleries. The flash detector confirms nothing on the page is silently broken.

How to use the flash detector

1. Paste the full address of the page you want to test into the box at the top of this page. Use the exact page you care about, such as your home page or a service page, because each page can give a different flash detector result.
2. Press the button and wait a few seconds. The tool fetches the page the way a visitor and a search engine would, then runs its checks. Nothing is installed, and you only need to enter your name and email to read the full result.
3. Read the verdict and the plain-English notes, make the changes listed under the fixes, then run the test again to confirm the problem is gone. Keep a note of the date and the result so you can show progress.

How to read your flash detector results

• Pass means no Flash found.
• Fail means at least one SWF reference that no modern browser will play.

How to fix problems the flash detector finds

• Replace Flash content with HTML5, CSS or video.
• Remove SWF files and SWFObject scripts.

Common mistakes

• Assuming the animation still works because it did on an old computer.
• Hiding the missing plugin message instead of replacing the content.
• Keeping Flash-only navigation that blocks both users and crawlers.
