Stickers for Telegram and WhatsApp
A picture becomes a sticker: WebP 512 × 512 with transparency, the right file size and an outline. Everything happens in the browser, files are not uploaded anywhere.
Telegram: one side exactly 512 px, size up to 512 KB, WebP or PNG format with a transparent background.
WhatsApp: size 512 × 512 px, WebP format, size up to 100 KB. The whole picture is fitted into the square.
The background is not removed. To get a sticker without a background, first remove it on the “Remove background” or “Transparent background” page.
Stickers for messengers require a strict format. Telegram accepts WebP or PNG in which one side is 512 pixels and the size is no more than 512 kilobytes. WhatsApp asks for WebP of 512 by 512 pixels and up to 100 kilobytes.
The page brings the picture to the right size and keeps the transparent background if there is one in the source. For WhatsApp the artwork is placed in a square with its proportions preserved, and for Telegram the canvas size adapts to the shape of the picture.
The file size is chosen automatically: the WebP quality is lowered exactly enough for the file to fit the limit of the chosen messenger. If the picture is too complex, add padding or choose WebP instead of PNG.
A white or colored outline makes the sticker stand out on both dark and light chat backgrounds. The outline thickness is set with a slider, and padding leaves free space at the edges so that the artwork is not cut off in the app interface.
The background is not removed here, so for a cut-out character first use the background removal page. Processing happens in the browser, files are not uploaded to a server, and the finished stickers can be downloaded one by one or all at once.
