A screenshot is one of the easiest sticker sources you already have: a meme someone sent, a game moment, a UI element you love. The trick is isolating the part you want from the rest of the capture. With the free LINE sticker cutter, you can crop, resize, and clear the background without leaving your browser.
Why screenshots work well
- Already digital. No photo blur, no lighting issues.
- Often flat backgrounds. Solid-color UI backdrops remove cleanly.
- Instant source. Capture, crop, done — no drawing required.
Step 1 — Capture just what you need
Start with the tightest screenshot you can. If you only want one icon or face, crop the system screenshot tool down to it. A smaller starting capture means less cleanup later. If you grabbed a whole screen, that is fine too — you will crop inside the tool.
Step 2 — Crop to the subject
Load the screenshot into the cutter and draw a crop box around the element you want. Keep a small margin so edges are not clipped, but drop the surrounding UI, text, and empty space.
Step 3 — Resize to 320×320
Set the output to LINE’s main canvas: 320 × 320 pixels. Center the subject and let any extra space stay transparent. The full spec, including tab and popup sizes, is in the size & format guide →
Step 4 — Remove the background
Use edge-based background removal: it clears the backdrop from the outer border inward and stops at the first non-background pixel. That keeps interior white (text, highlights) while the screenshot’s background disappears. Avoid blanket white-delete tools, which also eat white inside your subject.

Step 5 — Export as PNG
Save as PNG to keep transparency. JPEG would re-add a white box. Your screenshot is now a sticker.
Common screenshot pitfalls
- Busy backgrounds. A photo-within-a-screenshot has a messy backdrop. Crop tighter or accept extra cleanup.
- Small text. At 320×320, tiny screenshot text becomes unreadable. Use screenshots with bold, large elements.
- Watermarks. A screenshot of someone else’s watermarked image carries that mark into your sticker. Use your own captures.
- Saving as JPEG. Kills transparency. Always PNG.
FAQ
Can I crop a sticker from a screenshot of a sticker?
You can, but the result inherits the original’s size and any background. For a cleaner result, start from the original art when possible.
Will the screenshot’s background be removed automatically?
Not automatically — you run the background removal step. Edge-based clearing handles most flat screenshot backdrops well.
Is it okay to use screenshots of other people’s content?
For personal use, often yes; for publishing a set others can download, use your own captures to avoid copyright or watermark issues.
What size should the final sticker be?
320×320 for the main canvas. Details in the size guide →
