About this tool
Many ZIPs are made with fast, light compression. This tool unpacks yours and packs it again at the highest level, then tells you how much space you saved. If the new file is not smaller, you get your original back unchanged. If your ZIP has a password, enter it and the new one keeps it.
Common questions
Will my files change?
No. Every file keeps its content and name. Only the way it is packed changes.
Why was there no saving?
ZIPs of photos, videos or already compressed files can't shrink further, so the original is returned.
Is it free to use?
Yes. You can use it without an account a few times a day, and a free account raises the daily limit. Nothing is added to your file unless you ask for it.
What happens to my files?
Your files are only used to run the tool you chose, and they're deleted automatically after about 24 hours.
Do I need to install anything?
No. It all works in your browser, on any computer or phone.
