Current Behavior

I have an important photo that I need to send to someone without any compression so they can store it permanently (e.g., a family photo).
Even if I send this photo using the document icon (instead of the picture icon), the recipient still receives a compressed image after downloading it.

Expected Behavior

The receiver should download the photo in its original size if it was sent as a document.
The receiver should download a compressed version of the photo if it was sent as a picture.
(This should work the same way as in Telegram Messenger.)

Steps To Reproduce

1. Prepare an image larger than 3 MB.
2. Send the image in a session using the document icon (not the picture icon).
3. The receiver downloads the photo.
4. The receiver checks the file size.
5. The downloaded image is smaller than the original one.

Android Version

Android 14

Session Version

1.27.0

When sending media, we currently recompress images to strip metadata, though the impact on file size should be minimal. By default, all media is compressed. However, we may consider adding an option in the future to send original files without removing metadata. I've added a feature request to our internal backlog for consideration (SES-4547).
