Using my Telegram bot, I attempted to download an image via the getFile method. Although the download completes successfully, the resulting file is only around 1.7 KB, which is much smaller than what appears on my mobile device. Has anyone experienced this issue, and could there be an explanation for this significant size discrepancy?
hey, i had a similar issue - i was unknowingly dowloading a thumbnail, not the full image. double-chech the file_id you use so you get the complete file. small quirks in telegram API can cause this, so it worked for me after switching.
I encountered a similar problem while working with my Telegram bot. In my case, the root issue was that the file_id sometimes references a lower resolution preview rather than the full image file. After thorough debugging, I confirmed that the file referenced was indeed not the original image uploaded by the user. I resolved it by validating the context of the file message and ensuring the image was uploaded as a document if a high-resolution copy was required. As a result, careful verification of the file_id source and the message type was essential to obtain the correct image file.
I had a similar problem when developing my own Telegram bot. Initially, I ended up downloading what turned out to be a preview rather than the full image, much like what was described. I had to look more carefully at the file identifier and the context in which it was provided in the API’s response. It was important for me to double-check the parameters for getFile. Adjusting the logic to ensure the bot referenced the complete upload rather than a thumbnail made all the difference.
hey, im not sure if its a bug or design from telegrm. i fixed this by checking the meta data in incoming messages. sometimes you get a lowres image, so for full quality, try sending them as a document instead.
