The problem

Making custom emoji starts with a clean transparent cutout — normally a Photoshop job. Most people give up before they even get to resizing.

The NSS solution

The NSS Background Remover cuts your subject out of any photo with AI and hands you a transparent PNG — the clean starting point for a custom emoji or sticker. No design skills required.

How to use it

  • 1

    Discord server emoji

    Turn any meme, pet photo, or reaction face into a transparent cutout, then resize to Discord's 128×128px emoji size.

  • 2

    Slack workspace emoji

    Create branded or fun custom emoji for your Slack workspace. Export a transparent PNG and upload via Workspace Settings → Customize → Emoji.

  • 3

    Telegram sticker packs

    Telegram requires 512×512 PNG stickers with transparent backgrounds — export your cutout and upload to the @Stickers bot.

  • 4

    Notion custom emoji

    Notion accepts any PNG for page icons and emoji. Export from NSS and upload to any Notion page as a custom icon.

Step-by-step guide

  1. 1

    Pick your source photo

    Selfies, pet photos, product shots, and logos all work. Clear subject against a plain background gives the cleanest result.

  2. 2

    Drop into the Background Remover

    Go to /background-remover and drop your image. The AI removes the background automatically — usually in a few seconds.

  3. 3

    Refine and choose your background

    Clean up edges if needed, and keep it transparent or add a solid colour.

  4. 4

    Download

    Download the transparent PNG, then resize to each platform's emoji size.
