FAQ
Frequently asked questions
Will converting JPG to PNG improve image quality?→
It won't restore quality lost to JPG compression, but it prevents further quality loss during future edits and saves.
Why are PNG files larger than JPG?→
PNG uses lossless compression, which preserves all pixel data. This results in larger files but no quality degradation.
Can I add transparency to a JPG by converting to PNG?→
Converting creates a PNG with a solid background. You'd need to edit the image afterward to add actual transparency.
When should I convert JPG to PNG?→
When you need lossless editing, want to prevent further quality loss, or need PNG format for specific platforms.
Does the conversion process modify my original JPG?→
Never. File Studio creates new PNG files and leaves your original JPGs completely untouched.
Can I batch convert JPG to PNG?→
Yes. Process entire folders of JPG images in a single operation.
