You’ll have the same options Photopea offers plus a couple more that may come in handy. On Photoshop, go to File, Export, and choose Save for Web (Legacy)…. You’ll also be able to see how changing each of these variables affects the final file size, so you can more easily keep things below 128KB. In the dialog box that pops up, you’ll find a couple settings you can play around with to further edit your emoji, including image size and looping options. On Photopea, go to File, Export as, and choose GIF. This is especially handy when the line changes direction abruptly, like at a corner or sharp edge. You can also drop anchor points at will by left-clicking your mouse.

If the tool already has an anchor point in place, you can remove it by hitting Delete on your keyboard ( Command + Delete on a Mac). If that happens, just move your mouse to get it back on track. This works great when you have a clearly delineated figure, but not when the colors of the background are too similar to those that make up your emoji.Īs you guide it, the lasso will sometimes deviate from where you want it to go. This tool draws a selection path around similar pixels and sets it in place by dropping tiny squares called anchor points. The last variation with a magnet on it is the one you want. To find it, hit the L key three times or click and hold the lasso icon on the dropdown menu (it’s third from the top on the left sidebar). Photopea doesn’t have a magic wand option, so the magnetic lasso will be your weapon of choice. If you can’t be bothered to cut along the outline of whatever you want to use as an emoji, or don’t know how, using a square photo will still work. Don’t worry about transparent backgrounds either.

It’s not the best aesthetic, but if you need to deliver a punchline quickly, it’s worth a shot. The ratio is also not an issue, as Slack will use your image’s width and paint the remaining space (above and below) black. If you use a bigger file, Slack will automatically resize it to fit-I uploaded an 811KB photo (3000 x 1800 pixels) and the program didn’t even stutter. The platform limits the image size you can use to 128KB and encourages square pics with transparent backgrounds, but these instructions are somewhat flexible.

If you know how to snap a photo and do basic edits such as cropping and changing brightness and contrast, you are perfectly capable of making a Slack emoji. Slack emojis for beginners: the JPEG Your favorite meme deserves to be a Slack reaction.
