Unable to upload some images to Roblox without failing or mangled results


I see, but how come when I uploaded the same file again it suddenly decided to work?



Will uploaded Decals be fixed later or we’ll have to upload them again once the problem is solved?



I think these will need to be uploaded again. The files we’ve seen exhibiting this issue appear to be broken during upload.



Looking at the two underlying images you uploaded @RuizuKun_Dev, the correctly rendered one is 32bit color depth, the black-background one is 8bit. If you’re on a PC, you can see the bit depth of a PNG by opening the properties window for the file (right-click -> Properties) from explorer and going to the details tab.



I see, I must have mistaken it for the same file.

Please let us know when the issue is resolved.

I would wait until then before uploading any decal to Roblox.



ah thank you



Ah, nice to see this is being worked on. I had simple single colour red bat wings with a transparent background saving with a black background today.
Checked the image properties and it is 8 bit.
I’ll give it a few days for you guys to fix then check back here.



Jpg is unaffected and upload fine.

Here are some example images that got inverted/outlined/line-patterned when uploaded. I tried uploading newly created pngs, editing pngs, and old pngs downloaded from the internet a year ago.

Symptoms include:

  • Scanlines over image
  • Flipping of color between black/white
  • Cropping of images (half goes missing)
  • Transparent pixels become solid

Adding color helps. Must be an issue with roblox’s new compressor change




still broke

Has anyone tried this recently? Has it been fixed?

This unfortunately still occurs, I encountered this about ten minutes ago as I had forgotten about this bug.

Image uploading still doesn’t appear to work in terms of badges, unfortunately.


This is a 24-bit .png I’ve attempted to upload, and it uploads fine.

The same image, when converted to 8-bit depth, is not recognized as an image by Roblox as demonstrated.

Both 24 and 32-bit depth seem to work out fine, but uploading either as a badge image doesn’t work, throwing up this error:

Until then, I’ve decided to hold off on badge uploads. Image/decal uploads work fine, however.

update: 4 hours later, and even more attempts to get the badge uploaded later (including compression)… still nothing. :confused: I’m convinced that image uploading for badges is completely broken for me, or something is very wrong with my computer.

(Yes, the above image also failed to upload. 24-bit PNG.)

Seems like a parallel issue to this – consider creating a new bug report if badge uploading fails with literally all images (all png depth levels, jpeg, etc).


Unable to create badges

Now I’m experiencing this problem. I made an image in Paint.net from scratch, saved it as a PNG, and got mangled results.

I uploaded it from studio, and oddly enough, it looked fine in the game image section but not actually in game. Resaving it as a JPEG fixed the problem. I can attach a repro if needed.

@TobotRobot Would you be able to give an update as to how Roblox is progressing on a fix? Thank you.



I think it got fixed cause im not having this problem anymore since yesterday.



Hey, I believe we shipped a change on March 12 to fix 8-bit PNGs having mangled transparency (or worse).

We have been unable to reproduce the issue where images fail to upload with the message: “Upload failed. Make sure what you’re uploading is an image.”, but I’m hoping these two issues are related and that fixing one fixes the other.

I had no trouble, just in-case I’ll provide a link: https://www.roblox.com/library/2982761109/testformistertitanic44



I am unable to upload 32 bit, 24 bit and 8 bit pngs. Which is making it very frustrating due to being unable to upload any decals to roblox.
I tried uploading some of the exact same images to one of my alt accounts and roblox allowed their upload, so I assume it’s an issue to do with the Beta program.
Further Update
It isn’t just the beta, I was uploading on an alt and then after 3 uploads the problem continued. Large issue this as it means I can’t change my Group Logo or upload a single decal.
