Most sticker work happens on a computer only by habit. In 2026 you can do the whole thing on your phone: take a photo, clean it up in a browser-based tool, and hand the PNG to the LINE Sticker Maker app. No Photoshop, no desktop. The HailouTec cutter runs in mobile Safari and Chrome, so the prep step works on either platform.
What you need on both platforms
- A source image (photo, screenshot, or drawing app export).
- A browser (Safari on iPhone, Chrome on Android).
- The LINE Sticker Maker app for the final publish step.
- Target size memorized: 320 × 320 px main canvas.
iPhone (iOS) steps
- Capture or pick. Use the Camera app or Photos to get your source image.
- Open the cutter. In Safari, go to the free sticker cutter and load the image (Safari can pull from Photos).
- Crop & resize. Crop to the subject, set output to 320×320, center it.
- Remove background. Run edge-based clearing so the backdrop goes transparent.
- Export PNG. Save the result; Safari lets you download or send to Files/Photos.
- Publish. Open LINE Sticker Maker, import the PNG, and submit.
Android steps
- Capture or pick. Use the Camera or Gallery app for your source.
- Open the cutter. In Chrome, load the free sticker cutter and select the image.
- Crop & resize. Same as iOS: crop tight, output 320×320, centered.
- Remove background. Edge-based clearing keeps interior white intact.
- Export PNG. Download to your device storage.
- Publish. Import the PNG into LINE Sticker Maker and submit your set.
Mobile-specific tips
- Use a stylus or finger for tight crops — phones are great for precise cropping.
- Check at small size. Pinch-zoom out to confirm the sticker reads well at chat scale.
- Keep the source high-res. Phones shoot big photos, which downscale cleanly to 320×320.
- Save as PNG, not the default share format. Some apps recompress to JPEG; export PNG to keep transparency.
FAQ
Do I need any app besides LINE Sticker Maker?
For prep, no — a browser-based cutter like HailouTec handles crop, resize, and background on the phone. LINE Sticker Maker is only for publishing.
Why does my exported sticker have a white box?
It was likely saved as JPEG, or the background was never cleared. Re-export as PNG after removing the backdrop.
Can Android and iPhone use the same method?
Yes — the cutter is browser-based, so the steps are nearly identical; only the browser (Safari vs Chrome) and file-saving UI differ.
What size should I aim for?
320×320 for the main canvas. The size guide → covers tab and popup sizes too.
