Connected-region detection
When transparent gaps are clear, the splitter creates pieces from the shapes that are actually present, with no forced target count.

Split a Sticker Sheet into Separate Transparent PNGs
MewSticker finds actual connected non-transparent regions in a sticker sheet. A valid single connected subject stays as one sticker instead of being cut into an arbitrary grid. For shadows, overlaps and unusual spacing, restore editable boxes, add manual regions and verify every result before batch export.
Upload a sticker sheet 中文From an idea to usable sticker assets
Valid one-piece results
A sheet with one connected subject remains one useful sticker rather than being divided just to create more files.
Editable automatic boxes
Adjust recovered regions or draw manual boxes when shadows, overlaps and decorative details need human judgment.
Review and batch export
Inspect every crop, refine edges and download a single result or export the verified collection as transparent PNGs.

How to separate stickers from one image
Transparent sheets with visible gaps are the strongest inputs, while complex artwork remains editable.
1. Upload the source sheet
Use a transparent PNG when possible. For a flat JPG background, remove the connected background before relying on region detection.
2. Start automatic splitting
The tool analyzes how non-transparent pixels connect and creates a result for each real independent region.
3. Inspect overlaps and details
Check that shadows did not join neighbors and that small captions or decorative marks were not separated incorrectly.
4. Correct and export
Edit the boxes for special cases, confirm each crop and download individual files or a complete batch.
Know the boundary
When a sticker sheet needs manual correction
Visual separation does not always mean pixel separation, so some sheets require a final human decision.
Shadows connect neighboring art
Wide drop shadows can merge subjects into one region. Clean the background or correct the intended crop manually.
Stickers overlap each other
A splitter cannot infer pixels hidden behind another sticker. Use the original separated artwork when full shapes are required.
Decorations sit away from the subject
Stars, captions and small marks can appear as separate regions. Combine them with the subject using an edited box.
Check the deliverables
Prepare cleaner files after splitting
Splitting defines crop regions; transparency, borders and consistency still deserve a final preview. Review every exported file at its intended display size, use clear filenames, and keep the original sheet beside the separated assets so future revisions remain traceable.
Inspect edges on a checkerboard
Look for leftover background color, translucent noise and thin details cut by the crop.
Apply a consistent border
For a coordinated set, preview the same border extent, color and opacity across the collection.
Keep the original sheet
Retain the source so a different splitting or edge treatment can be produced without quality loss.
Frequently asked questions
Does the splitter force a requested number of stickers?
No. It returns the actual connected regions it detects. One complete connected subject is a valid one-piece result.
Can it reconstruct stickers that overlap?
It cannot reliably recreate hidden pixels. Manual boxes can change the crop, but the missing artwork needs an original source or redrawing.
Can I split a JPG sticker sheet?
Yes after background cleanup, but a transparent PNG with clear gaps usually gives more reliable connected-region results.
Can I download all separated stickers together?
Yes. Review the pieces first, then download one sticker or batch-export the verified collection.
