Resize product photos for Amazon
Every photo comes out as a 2000 × 2000 JPG with white bars where its shape differs, so the whole product shows and zoom works.

What Amazon asks for
Product images should be at least 1,000 pixels on the longest side, and 1,600 or more for zoom. The main image needs a pure white background (RGB 255, 255, 255), and JPEG is the preferred format.
White bars, not a new background
Graviton squares the photo with white bars; it doesn’t remove the background behind your product. For the main image, shoot or edit the product on white first.
Frequently asked questions
Can I use another size?
Yes. Tap Resize, or under Resize in the settings pick another size; the white bars follow. Etsy and Shopify both work well with 2000 × 2000 too.
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.
