Frequently Asked Questions

How does the Compressor shrink file sizes so effectively?

It utilizes lossy canvas sub-sampling to prune redundant pixels and compress metadata headers, keeping the file visually identical while slashing overall storage footprint.

Is there a file size limit for compiling or compressing graphics?

Since all processing is handled on your local device CPU, there are no artificial limits—you can compress files of any size without registration.

Does compressing a PNG file preserve its alpha transparency channels?

Yes, our smart transpiler preserves standard alpha transparent backgrounds during the processing cycle.
