Will the file size increase?

PNG uses lossless compression, so file size may be larger than JPEG.

Are images sent to a server?

No, all processing happens in your browser.

Does quality degrade after conversion?

Converting JPEG to PNG (lossless) adds no further quality loss. However, the original JPEG compression artifacts are preserved as-is.

Can multiple files be converted at once?

Yes. Drop multiple JPEG files together and they will be converted and downloaded one by one.

Is there a file size limit?

Up to 50MB per file is supported. Files exceeding this will result in an error.
