Frequently Asked Questions

How many images can I convert at once?

There is no hard limit, but very large batches may be slow depending on your device. Batches of 20–50 images work smoothly.

Are my images sent to a server?

No — all conversion happens locally in your browser. Your images are never uploaded.

Can I convert PNG to JPG in bulk?

Yes — upload all your PNGs, select JPG as the output format, and download the batch.

Can I set different quality for each image?

A single quality setting applies to the entire batch. Convert individually if you need per-image quality control.
