Signal beta allows users to send images in 12-megapixel resolution
The 5.11.0 beta version of Signal allows users to send high-resolution images to each other. For this, the chat app introduces a new menu to set the quality of an image.
By default, images are still sent at approximately 2-megapixel resolution, but optionally this can be increased to ‘4k’, can be seen at the update description on APKMirror. That turns out to be a 12-megapixel resolution. It is not known when the feature will come to the stable version of Signal.
Android Police has tried out the feature and shows that users can choose standard or high quality when sending an image. The site used an image with a resolution of 6944×9248 pixels and file size 11.6MB to test it. In the standard quality, Signal made an image of this with a resolution of 1201×1600 pixels and a file size of 204KB. The high-quality variant has a resolution of 3075×4096 pixels and a size of 1.4MB.
Signal is not the first chat service to allow users to send images in higher quality. Telegram allows users to send full-size images. In WhatsApp, higher resolution images can be sent when users send them as documents.
