Telegram Sticker online with ImgShifter

Telegram Sticker Maker - 512x512 PNG sizes any image to 512 x 512 (1:1) PNG with transparency preserved - the exact spec the platform requires. Non-square sources are scaled to fit and padded with transparent pixels on the shorter axis so your subject keeps its original aspect ratio and nothing gets cropped off. If you'd rather crop to a tight square first (zoom into a face, for example), use the Crop Image tool with 1:1 ratio before running it through this maker.

Telegram's sticker spec is strict - exactly 512 px on one side and PNG with transparency required. This tool produces 512 x 512 with transparent padding so the rule is satisfied automatically. Upload by sending the PNG as a file (not photo) to Telegram's official @Stickers bot. Sending as photo strips the alpha channel; sending as file preserves it.

Everything runs in your browser. The resize and PNG export happen on your device using the Canvas API. iPhone HEIC files are decoded locally with a WebAssembly module before sizing. No upload, no signup, no watermark.
