Why convert GIF to AVIF?
GIF is a decades-old format limited to 256 colours: fine for simple animations, but photos look banded and files run large. AVIF is the newest web format and is often half the size of a JPG, but support outside web browsers is still patchy.
What happens to quality?
The first frame is encoded with libavif at quality 75, keeping transparent areas. An animated GIF keeps only its first frame.
Frequently asked questions
Which browsers show AVIF?
Every current version of Chrome, Edge, Firefox and Safari. Some older apps and upload forms don’t, so choose GIF to PNG or GIF to JPG for those.
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.
