Frequently asked questions
Are my JPG images uploaded anywhere?
No. Your images are converted on your own device and never sent anywhere — there is no upload step at all. Nothing to store, nothing to delete afterwards, because we never receive your files.
Does converting JPG to JPEG change my image?
JPG and JPEG are the same format, so the format itself changes nothing. The tool re-saves the file with a clean .jpeg extension and can re-compress it to a smaller size if you turn compression on.
Can I convert many JPG files at once?
Yes — drop in a whole batch and convert them together, with a live before/after for each image. The Free plan handles up to 10 images per batch; Pro removes the limit and adds .zip export.
