Why edit images without uploading to a server?

Photos, screenshots and scanned documents often contain private details you shouldn't have to upload just to resize or compress them. NearIMG runs the entire process locally in your browser, so nothing is transmitted anywhere.

Does it keep the animation?

No — JPG is a still image, so the GIF's first frame is converted.

Why is the background white?

JPG has no transparency, so transparent GIF areas are filled with white.

Does it work offline?

Once the page is loaded, all processing happens locally in your browser.
