Why convert WebP to PNG?
WebP is a web format that is usually 25–35% smaller than JPG, but some editors, upload forms and older apps reject it. PNG is lossless and supports transparency, which suits screenshots and graphics but makes photos large.
What happens to quality?
The conversion is lossless: every pixel of the WebP, including transparency, is kept exactly as it is.
Frequently asked questions
Why is the PNG bigger than the WebP?
PNG is lossless, so it stores every pixel exactly. That makes it larger than WebP, but it is ideal for editing.
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.
