Discord Emoji online with ImgShifter

Discord Emoji Maker - 128x128 PNG sizes any image to 128 x 128 (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.

Discord renders custom emojis at 32-48 px in chat and 128 px in the picker, so simple bold designs with high contrast read much better than detailed photos. The 256 KB upload cap is generous - PNGs of typical emoji artwork compress comfortably under 100 KB at 128 x 128, leaving headroom. If your design ends up over the cap, simplify the artwork or run the output through the compressor afterward.

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.
