Frequently Asked Questions
Does converting JPEG to PNG improve quality?
Converting JPEG to PNG does not restore the quality lost during JPEG compression. However, it prevents any further quality loss since PNG is lossless. For best results, convert from the highest quality JPEG source available.
Why is PNG larger than JPEG?
PNG uses lossless compression, which preserves every detail. This results in larger file sizes compared to JPEG's lossy compression. The trade-off is perfect quality and transparency support.
Can I convert JPEG signature to PNG for transparency?
Yes! Converting your JPEG signature to PNG format allows you to later remove the background and create a transparent signature. Use our Background Remover tool after converting to PNG for the best results.
Is JPEG the same as JPG?
Yes, JPEG and JPG are the same format. Both use identical compression. The .jpg extension is simply a shorter version of .jpeg that originated from early Windows' 3-character extension limit.
