Uploading .TGA file crashes website

Reproduction Steps
In the develop page, under decals, attempt to upload an image of .TGA format. Then, click “Upload”

Expected Behavior
I expect the image to upload normally and without a crash.

Actual Behavior

The website embeds itself into the upload area for a moment, and then you see a “bad request” page.

There are no workarounds. In fact, attempting to press “back” on the error page will reproduce the issue instantly.

Issue Area: Roblox Website
Page URL: Create - Roblox
Impact: High
Frequency: Constantly


I am not replicating the crashing part of this bug, however I do get a message claiming the file failed to upload.

In the meantime, I suggest using an application like this:


Conversion isn’t a problem because I use GIMP, which can export any image format. My goal here was to export with TGA instead of PNG to attempt to fix another issue.


Well this isn’t really a bug… why you may ask?
Well .TGA files aren’t supported, so it’s just a different way of saying it isn’t supported or it couldn’t handle it. Stick with PNG, JPG, or JPEG I think it’s called.

It’s a bug because it should gracefully handle the error and tell you that .tga is not accepted. There is no clear indication to the user. This is the bug.


Actually… they are supposed to be.


Out of the four file formats requested (.png, .tga, .jpg, .bmp), only .tga crashes the site.


It’s alright! And yes, it is still happening.

When I go to upload audio/decal, I have only 2 options that work, those are the 2, Any fails to upload (gets declined/privates afterwards) so I said in my post that this was a theory, but it’s highly possible.

You said nothing about it being a theory. I would go as far as to say it’s extremely unprobeable, and going back to the original topic, this is a bug, not a feature.

I do remember .tga working before, not sure what they’ve changed to break it.

Hi everyone!

We’ve filed a ticket to our internal database, and we’ll follow up when we have an update for you.

Thanks for the report!


Has there been any update to this? Still seeing this issue on 5/13/22. This is a blocker for me at the moment. Thank you.


Our engineers are still working on it, I don’t have any updates at the moment, unfortunately.
But as a workaround for now, you can convert the file to a PNG with the same transparency, and it should work.

Will come back with a reply as soon as I have news, thanks for your patience!


I have had the same issue [receiving the 400 bad request page] while uploading .pngs for months.

Been seeing this issue as well, for months. Whenever I run into this, I just go back to the Create page [hitting it at the top of the screen] and then continuing to re-upload the object. Sometimes it takes 3-4 times uploading to finally get it through.

Thought maybe it was an issue with file sizes [PNG & TGA are bigger than JPG & GIF], however even when I just tested a 28 kb TGA causes it to reliably 400 error.

This is causing major blockers for me recently as well, since we can’t upload TGA files in Studio either, as of 5/18/22. Issue has been ongoing since at least 5/07/22

This is still an issue. The site and creator docs still claim TGA is supported, but it always redirects to a 400 error.
