See who liked you without Tinder Gold

Result

Images of people who liked you at 640x800, 320x400, 172x216 without Tinder Gold.

So

Tinder likes without Gold comes up like this, a blur effect on the photo(s).

Initially, I thought that the blurred images were sent from their servers itself. A simple inspection on the code

-webkit-filter: blur(8px)
filter: blur(8px)

Okay, so they are applying a blur effect with CSS. Disabling this would give me a raw image of 172x216 dimension. Exploring media items, the recently liked (only one) would be of 320x400 dimension.

The 172x216 in the URL is the dimensions. Changing it to 320x400, would give me an image of that dimension. All the images were coming from the same endpoint. So, I tried changing it to random dimensions with the same aspect ratio which like I guessed didn't work because they were not storing (x dimension) in their server.

Also, noticed that my profile picture was of better quality.

To my surprise, that too was coming from the same endpoint. So, now I know that Tinder stores images in 640x800 also.

So, that's that.
