Start with a good image
- Use the largest, sharpest version of the image you have. Crops can't have more detail than the original.
- A plain white or light background works best. Busy or dark backgrounds are not supported.
- Leave a small gap between objects if you are making the sheet yourself.
- PNG files give cleaner edges than heavily compressed JPGs.
Common problems and fixes
| Problem | What to do |
|---|---|
| Two objects came out as one | Lower Join nearby parts, or use Click to select on each object. |
| An object is split into pieces | Raise Join nearby parts, or use Draw boxes around the whole object. |
| Pale parts of an object are missing | Lower Color sensitivity or White tolerance, or paint them back with the Restore brush. |
| Tiny specks or shadows appear as objects | Raise Ignore pieces smaller than. |
| A small object is missing | Lower Ignore pieces smaller than, or pick it with Click to select. |
| Part of the artwork was erased as a grid line | Click Restore lines, or restore just that part in the editor. |
| Grid lines still show in crops | Make sure Remove grid & border lines is on, then erase leftovers with the Erase brush. |
| White inside the object became see-through | Set White pixels inside an object to Keep them. |
| Objects are cropped too tightly | Increase White margin around each object. |
| A thin white edge shows on dark backgrounds | Choose Dark in the viewer to check, then trim the edge with the Erase brush. |
What each setting does
| Setting | What it changes |
|---|---|
| Remove grid & border lines | Erases thin straight lines that run across the sheet before cropping. |
| Auto-detect method | Colored pixels + dark outlines suits cartoons and clipart; Difference from background suits pale or greyscale art. |
| Color sensitivity | How colourful a pixel must be to count as part of an object. Lower finds paler colours. |
| White tolerance | How different from the background a pale pixel must be to count as part of an object. |
| White margin | Extra space added around each object. |
| Join nearby parts | Small separate bits (a leaf, a caption) within this distance join their object. |
| Ignore pieces smaller than | Removes pieces smaller than this share of the biggest object. |
| White pixels inside an object | Keep whites inside the object (eyes, highlights) or make every white transparent. |
| Crop shape | Keep the object's own shape, or place it on a square canvas. |
Export tips
- For stickers and designs, use PNG with a Transparent background.
- For photos in documents or email, use JPG — smaller files, always with a solid background.
- For websites, WebP gives small files with transparency.
- For printing a contact sheet, use PDF with A4 or Letter pages.
- Use 200% or more only when you need larger files; upscaling doesn't add real detail.
On a phone
- Open ⚙ Settings only when you need to change something — it stays folded to keep results close.
- After tapping an object, watch for the message at the bottom and the blue outline on the preview.
- Use the bottom bar for quick access to Rename and Export.
