Instant messaging apps compress photos and videos to share them rapidly using less bandwidth. Compressing the images also ensures the recipient can download and view them as soon as possible, even on slow networks.
For most cases, media compression is great. But if you ever want to send an image of a document, text, group picture for printout, or any other serious purposes, you might want to stick with the highest resolution. If you don't, the final image can be blurry, unclear, unprofessional, and with finer details lost.
To address this, here are several ways to send a picture or video clip in full, uncompressed quality on iMessage, WhatsApp, Telegram, and Signal from your iPhone or iPad.
