Graviton converts them to PNG right in your browser.
- 3
Download each PNG, or all of them as one ZIP.
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 download them one by one or together as a ZIP that keeps the original file names. On Free, each image counts once a day against your 3 downloads; Pro has no daily limit, so the whole batch downloads at once.
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.
