Frequently asked questions
Does JPG to PNG improve image quality?
No. PNG avoids adding another lossy compression step, but it cannot restore detail that the JPG already discarded.
Will JPG to PNG make the file larger?
Often, yes. PNG is lossless and can be much larger than a compressed JPG, especially for photographs.
Can I convert multiple JPG files to PNG?
Yes. Add several static JPG files, convert them in one local batch, and download each verified PNG result.
