20 PNG files → WebP → one ZIP
Preparing a full folder of website images should not mean repeating the same settings file by file. Add up to 30 PNGs, choose shared quality and dimensions, then download every WebP in one archive.

Add your images
Drop PNG files anywhere in the converter or choose them with the button. You can add up to 30 files, each up to 50 MB.
Choose shared settings
Set WebP quality and a maximum side. Shared settings apply to the batch, while any individual image can still use a different crop.
Download the result
Wait until every file is ready and select “Download ZIP”. Original names are kept and the extension changes to .webp.
Recommended settings
For most website photography, start at 75% quality. Compare 92% when fine detail matters; 50% is often enough for small thumbnails.
Original size
Use it when dimensions are already correct and you only need a format change.
1024 or 2048 px
A practical ceiling for website content that avoids sending unnecessary pixels to visitors.
ZIP or separate files
ZIP is quickest for a large batch. Separate downloads are convenient for just a few images.
Bulk conversion questions
Will transparent PNG files stay transparent?
Yes. WebP supports transparency, and it is preserved during PNG conversion.
Are my images uploaded to a server?
No. Files are processed locally in your browser and never leave your device.
Can one file have a different crop?
Yes. Select it in the filmstrip and adjust its shape or crop; the rest keep the shared settings.
Your files stay on your device.
