Photos

Every photo action costs 1 credit. Send the photo as a file (paperclip, then File) whenever you can: Telegram compresses a normal photo and strips its metadata before the bot ever sees it, so a photo sent the usual way can still be compressed, converted or made into a sticker, but its original quality and metadata are already gone.

Accepted images: JPG, PNG, WebP, AVIF, HEIC/HEIF, TIFF and BMP.

Compress

Choose the strength: 20, 40, 60 or 80 percent, or Maximum. A stronger setting gives a smaller file and lower quality. If the file would not get smaller, nothing changes and the credits are returned.

Convert

Converts to PNG, JPG, WebP, AVIF or HEIC. This is the quickest way to turn an iPhone HEIC into JPG, or a PNG into a much lighter WebP.

Reduce resolution

Choose 50 percent of the original size, or a long side of 2560, 1920 or 1280 px. A picture is never enlarged.

Remove GPS and metadata

Removes the data that photos carry along: GPS location, camera and lens, capture date and time, editing software, author and copyright, and other metadata such as XMP and IPTC fields (edit history, captions). The bot tells you what it removed. This action needs the original file: a photo sent as a compressed Telegram photo has no metadata left, so the action is not offered for it.

If the file has no metadata, nothing is changed and the credits are returned.

Stickers

A photo can also become a sticker; this is free. See stickers.
