OverByte
Reverse compression - making files bigger.
What it does
A reverse compression app. Instead of making files smaller, it makes them bigger. You can easily make a 10GB png out of a 25KB one.

- OAOverfitted a 900KB Transformer to Compress a 100MB CSV into 7MBJun 2026 · ▲112
I built an experiment that uses an overfitted transformer and arithmetic coding to compress individual files. Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output. On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte). It's pretty slow right now (roughly 20–30 minutes of training and 45 minutes each for compression and decompression on my…
