When a folder is full of mixed formats and you need them all as WebP or all as JPG, converting one at a time is painful. Batch conversion handles the whole set in a single pass.
Why convert in bulk
Migrating a photo library to WebP for a faster site, standardizing client files to JPG, or preparing a set of icons all involve many files at once. One setting applied to the whole folder keeps everything consistent.
How to batch convert images
- Open the Batch Image Converter.
- Add all your images, in any mix of formats.
- Choose the output format and quality.
- Download the converted set as a zip.
Conversion runs in your browser, so even large libraries stay private.
Choosing the target format
- WebP for the web, smaller files at good quality.
- JPG for maximum compatibility.
- PNG when you need transparency or lossless copies.
Convert then compress
After converting, run the batch through the Bulk Image Compressor for even smaller files. For a single file, the Universal Image Converter is quicker.
Frequently asked questions
Can I convert many images to WebP at once?

Do all the images need to be the same format to start?
No. You can mix JPG, PNG, and other formats in one batch and convert them all to a single target format.
Are my images uploaded during conversion?
No. The batch conversion runs in your browser, so files stay on your device.
