Why convert JPG to PNG?
JPG opens everywhere and suits photos, but it has no transparency. PNG is lossless and supports transparency, which suits screenshots and graphics but makes photos large.
What happens to quality?
The conversion is lossless, so no further quality is lost. The PNG is usually larger than the JPG because PNG stores every pixel exactly.
Frequently asked questions
Will converting to PNG make my JPG sharper?
No. PNG keeps the image exactly as it is, but it cannot restore detail the JPG already lost.
Are my images uploaded?
No. Graviton converts and compresses inside your browser, so your images never leave your device. Nothing is sent while you compress. When you download, the browser sends only a one-way fingerprint of the image, so the download can be counted and approved. Graviton stores none of it.
Can I process many images at once?
Yes. Drop up to 250 images at once and they are compressed together. Download them one by one or as a ZIP that keeps the original file names: 3 a day on Free, unlimited on Pro. On Free, each image counts once a day.
Is it free?
Yes. Compressing and converting are free and unlimited, with no account needed. Downloading needs a free account, which includes 3 downloads a day with every format and setting. Pro removes the daily limit.
