Frequently asked questions

How many images can I compress at once?
As many as you like. There is no file-count limit — add a whole folder and compress them together.
Can I download them all together?
Yes. Once the batch is done, “Download all” packages every compressed image into one ZIP.
Will a large batch slow down my computer?
The work happens in your browser, so very large batches use your device’s memory. For hundreds of files, compress them in a few groups.
Are the files uploaded?
No. Batch compression runs entirely on your device.
