What is Alpha Bleeder?

Alpha Bleeder is a multipurpose Discord Bot made for (mainly Roblox) Designers. Ever had these annoying outlines around your image after uploading it to e.g Roblox, even though it looked perfectly fine in your favourite graphic design software? We got you!


The phenomena described above happens after a technique called “Blending” is applied by game engines like Roblox. Long story short, blending is the technique of rendering partially transparent objects. (a value between 0 - 1 , like 0.25 )

But there is a trap — colours from fully transparent pixels (that you, by default, don’t see in usual 2D image viewers and editors) can still affect the final rendering output because when rendering we do filtering that can average RGB colours from neighbouring pixels.
The way to fix these problems is alpha bleeding, which means that your transparent pixels also need some sensible RGB values. It’s an effect of how the GPU is using alpha and averaging RGBA pixels, and it really affects all game engines that exist.
But some engines hide it better than Roblox. E.g. Unity does alpha bleeding for you automatically, during texture import, if you select Alpha is Transparency.
CGE Has a good explanation in their blog on Alpha Bleeding!

That’s cool and all, but I still don’t know what Alpha Bleeder does…

Yep, you’re right. Sorry!
Alpha Bleeder allows you to AUTOMATICALLY and just as important, FOR FREE remove these annoying “outlines” you will get if you upload an image to Roblox that has partially transparent pixels. That’s the reason we created Alpha Bleeder; previously, there was no easy and fast way to apply Alpha Bleeding to images. But now there is! all for free! So don’t waste any more time on these annoying and time consuming things, and let us automate it for you so you can spend more time on doing what you love; designing


The Alpha Bleeder bot originated with just 1 objective; Automated and smooth removing of the outline caused by the blending. These days however, we’ve received more and more requests to expand into other things.

The bot will also let you know when no transparent pixels were found in the image, and thus it’s perfectly fine to use!

thank u for coming 2 my sales pitch. I suck at these


I love this bot so much. I use it whenever I need to import my custom images into roblox. Super easy to use and its free. Keep up the good work.

Cool but why is this a bot and not just software? Instead of being guaranteed stable until drastic change, this is now reliant on the state of the servers you’re hosting it on, the willingness of you to support it in the future, and Discord’s servers. I don’t see any benefit to making this a bot since all it does is process images.


I guess you’re right, the drawback is that you are relying on the uptime of the servers its hosted on, aswell as Discord’ servers.

Luckily though, it is extremely rare for Discord to have an outage where messages can’t be sent (ans thus, neither Slash commands).

The reason I’ve chosen to implement it as a Discord bot actually has a few reasons;

  1. Originally, when it was intended for just my team of developers & friends to use, we were practically on Discord 24/7, sharing finished GFX assets, talking ideas and whatnot. This made it only the more logical choice to create it within the platform we were already so intensively using; we didn’t have to run a program or go to a website to do this.
  2. When I did some research after deciding to open the bot to public, I found out that people would much rather use it as SaaS, rather than them having to download some external program and set it up. Ofcourse with point 1 in this list, the choice was easy :smile:
  3. After learning about point 2, the reason I went for a Discord bot rather than a website, is because I simply saw more potential in a Discord bot. It’s far more easier to reach people (read; grow) with a Discord bot, than a random website out there, while the risks of uptime remain the same (whether it’s a Discord bot I’m hosting or a website)

I’m glad you think it’s cool though! :smiling_face:

Totally valid, although a standalone release or website on its own would still be cool.

Can vouch, the bot works super well and leaves no residue on images. 100% recommend, would be cool if you could create a website and release the source code!
