Frequently Asked Questions
Will converting JPG to PNG make the file size larger?
Yes, typically. Since PNG uses lossless compression, the resulting file will likely be larger than the original compressed JPG, but it will prevent future quality loss during edits.
Can I convert multiple JPGs at once?
Absolutely! You can upload and process up to 20 JPG images simultaneously in our bulk conversion workspace.
Is there a limit on image dimensions?
We support high-resolution images. The limit is primarily your browser's memory, though we recommend staying under 50MB per file for the smoothest experience.
