Quick start
Upload your image
Open the Object Cutter tool and click the upload box, drag a file onto it, or paste an image with Ctrl+V (⌘+V on Mac). JPG, PNG and WebP files all work.
Check the automatic result
Every object is detected and cropped straight away. The crops appear under Extracted objects, each with its own name, size and buttons.
Fix anything that isn't right
Pick objects yourself with Click to select or Draw boxes, adjust the Settings, or touch up a single crop with ✎ Edit.
Choose a background and names
Pick Transparent, White, Dark or any Color, and rename files one by one or all at once.
Download
Download a single image, or use Export to save everything as PNG, JPG, WebP, SVG or PDF — in one ZIP file.
1. Uploading an image
There are three ways to add an image:
- Click the dashed upload box and choose a file.
- Drag and drop a file from your computer onto the box.
- Paste a copied image or screenshot with Ctrl+V.
Your image is opened inside your browser. It is never uploaded to a server, so even large or private files are safe to use.
2. Automatic detection
As soon as the image loads, Object Cutter:
- works out the background colour (white, off-white or light grey),
- finds and erases thin grid and border lines so they don't join separate objects,
- groups connected coloured pixels into objects,
- trims the empty space around each object and makes the background transparent.
If lines were erased, a note under the preview says how many. Click Restore lines if a line is actually part of your artwork.
3. Click to select
Use this when two objects touch, or when auto-detect missed one. Choose Click to select, then click or tap an object in the preview. The tool traces all connected coloured pixels from that spot.
- The object gets a blue outline and a number on the preview.
- A message confirms it, with Undo and View buttons.
- Your picks appear first under Your selections, newest at the top.
If you click empty background, the message tells you to tap directly on the coloured part.
4. Draw boxes
Choose Draw boxes and drag across the preview to crop an exact rectangle — useful for text, logos with gaps, or anything you want to keep together. Boxes show in green. Remove a box or pick with the × button on its card, or all at once with Clear user.
5. Touch-up editor
Click ✎ Edit on any crop to open it large:
- Restore brush — paint over a missing line or part to bring the original pixels back. Faded areas show what was removed.
- Erase brush — remove leftover bits, such as part of a neighbouring object.
- Change the brush size with the slider or [ and ]; undo with Ctrl+Z.
Every crop has its own edits — changing one never affects another, even where they overlap.
6. Background
Under Extracted objects choose the background for your files: Transparent (see-through PNG), White, Dark or any Color. Thumbnails update immediately, and downloads and exports use the same choice.
7. Renaming files
Click a name on any card to type a new one and press Enter. To rename many files at once, click Aa Rename:
- Pattern — for example
sticker-{n}gives sticker-01, sticker-02… Other tokens:{name},{old},{w}x{h}. - Paste a list — one name per line, in order.
- Find & replace — change text in every name.
8. Viewing an object
Click Open (or ⤢ on phones) to see a crop full size. Use the arrows or ← → to move between objects, click the image to zoom, and ← Back or Esc to return. You can edit, download or export from here too.
