Frequently Asked Questions
Does PNG improve quality?
PNG is lossless, so it preserves every pixel exactly. JPG is lossy, meaning some detail is permanently discarded during compression. Converting an existing JPG to PNG will not restore lost detail, but no further quality loss will occur.
What is the transparent background option for?
PNG supports an alpha channel (transparency). If you select the transparent option, pixels that would be white in a JPG background become see-through in the PNG — ideal for logos and icons used on coloured backgrounds.
Is this tool free?
Yes, completely free with no limits on file count or size.
Will my 4K photo keep its full quality?
Yes. Conversion is lossless and preserves your image's full original resolution — including 4K photos. PNG never compresses away detail the way JPG does, so what you upload is exactly what you download, pixel for pixel.
