Frequently Asked Questions

How many images can I convert at once?
Our tool officially supports batch conversion of up to 500 images simultaneously. Because all processing happens in your browser (not on a server), the only limit is your device's memory.
Can I convert mixed formats (JPG + PNG) together?
Yes! You can drag in a mix of JPGs, PNGs, AVIFs, and WebP files. Our tool will detect each one and convert them all to your chosen output format automatically.
Is it faster than desktop software?
In many cases, yes. Because we use WebAssembly technology, we run at near-native speed without the need to install or update heavy software like Photoshop or Lightroom.
How do I download hundreds of files?
You don't need to click one by one. After conversion, simply click the 'Download All (ZIP)' button to get a single organized archive containing all your optimized images.
Is my data private?
100% Private. Unlike other batch converters that upload your photos to a cloud server (risking leaks), Creatoryn processes everything locally on your device. Your photos never leave your computer.
