Batch-compress images to a ZIP
How to use it
Batch compress takes several images and downloads a ZIP. Use it when many photos should meet a size you can attach, not when you need to crop each one carefully. Open a few results before you send the archive. If one picture is muddy, the setting was too strong for the set. Run again from the originals. The ZIP is built in the browser. NexTool does not receive the album. This is not PDF compress and it does not merge the pictures into one document.
The file stays in this browser. NexTool does not upload it and does not keep a copy after you leave the page. Download the result and check it before you send it on. If the tab runs out of memory, the job stops and the original is still the one on your computer.
