HOW PIKOZIP WORKS
From original to optimized.
See how PikoZip processes images locally and how to choose your settings.
Find your balance.
Set format, quality, width, and an optional target size. Compare your result.
Take the lighter route.
Download one image or the whole batch in a ZIP, with folder paths preserved.
What happens to your file?
Your browser reads the selected file, checks supported image types, decodes the pixels, and runs the chosen encoder in a separate worker. Encoding can resize down to your chosen maximum width and remove metadata from newly encoded output.
PikoZip then shows the actual result size and dimensions. Same-format, same-dimension outputs that are larger can be replaced with the smaller original. Explicit format conversions are delivered even when they increase size.
What stays in your hands?
The output format, quality setting, PNG mode, maximum width, and optional size goal are yours to choose. The comparison preview gives you a way to inspect the result before downloading.
The public optimizer does not save your image batch between visits. Keep your source masters separately, download the results you need, and clear the batch when you are done.
