The difference between sending an image (as wide as the message) and sending a file (iconified and accompanied by a filename) is represented in Telegram's user interface by the concept of compression; for example, “files” are sent from Telegram on Android if “Send without compression” is chosen, “images” are sent from Telegram Desktop if “Compress images” checkmark is checked. However, sometimes JPEG compression is not really necessary for the images and they could be better delivered without compression. Twitter understands that. Since January 2019 (see https://twittercommunity.com/t/upcoming-changes-to-png-image-support/118695 or the attached screenshot of the most relevant part) Twitter refrains from delivering PNG images as JPEG if the image is small enough (does not exceed 900×900 pixels), or if the PNG format implies that its pixels are already better compressed than any decent JPEG could (1-bit, or 2-bit, or 4-bit, or paletted 8-bit pixels in PNG), or if an attempt to compress PNG to JPEG is actually made…

Embed a large enough number of Telegram messages on a page in Telegraph (the site, not the Graph Messenger), open that page in Mozilla Firefox 86 (a screenshot of https://telegra.ph/MSiH-02-14 is attached here as an example), and then suddenly most of the embedded messages have problems of inufficient height and thus their bottoms are cut and not visible on the page. Only the first four lines of text are visible. (The browser's user might then try helplessly clicking on Telegram's logo in the top right corner of such embeds… but that logo's URL leads to https://core.telegram.org/widgets instead of the message's source.) Some messages have sufficient height and thus either a race condition or an execution limit might be suspected as a reason for some embeds to look fine at the expense of all the others. If this problem can be reliably reproduced by the developers, then I hope that the appearance of Telegram messages on Telegraph pages might eventually be improved for Mozilla Firefox.

Hello Telegram staff. I would love to see an option in Telegram Desktop that allow the user to select the quality to use to send images: low, medium and high. Happens that the current version of Te...
