FAQ
How many images can I compress at once?
There is no hard limit. Memory is the real constraint, so keeping batches under 500 images gives the best performance.
Will batch compression lower quality unevenly?
Every image in a batch uses identical parameters, so quality is consistent throughout.
Do filenames change in the ZIP?
No. Original names are preserved; only the extension changes to match the output format.
