A Smart Object is a layer that keeps the original image data intact, so you can resize, transform and apply filters without permanently changing pixels. Right-click a layer and choose Convert to Smart Object, then edit as usual. Filters become adjustable and removable.
Why Smart Objects Help
Normal layers lose detail each time you scale them down and back up. A Smart Object stores the source and reapplies transformations from it, so repeated resizing does not degrade the result. It also turns filters into editable Smart Filters with their own masks.
- Non-destructive scaling, rotating and warping.
- Editable filters with masks and blend options.
- Linked copies that update together.
- Raw files opened as Smart Objects can be reopened in the raw editor.
Step by Step: Working with Smart Objects
- Select a layer, then right-click and choose Convert to Smart Object. A small icon appears on the thumbnail.
- Resize or rotate with Free Transform. You can shrink and enlarge later with no loss from the stored source.
- Apply a filter from the Filter menu. It appears under the layer as a Smart Filter.
- Click the Smart Filter mask and brush in black to hide the filter in chosen areas.
- Double-click the filter name to change its settings, or the eye icon to turn it off.
- Double-click the Smart Object thumbnail to open its contents in a separate tab. Make changes, save, and return to see them update.
- Duplicate the layer using the new Smart Object via Copy option if you want a copy that is independent of the original.
- Use Layer menu options to replace contents, for example swapping a photo in a template.
Things to Watch
Some tools, such as the brush or clone tool, do not work directly on a Smart Object. You can add an empty layer above and sample from below, or rasterize the layer when you are sure you are finished. Rasterizing is permanent for that layer, so keep a copy first.
File size can grow because Photoshop stores the source data. Save a layered copy for future changes and a flattened one for delivery.
Smart Object or Normal Layer
| Task | Better choice |
|---|---|
| Resizing a photo several times | Smart Object |
| Sharpening with adjustable strength | Smart Object |
| Direct brushwork or retouching | Normal layer |
A good habit is to name your Smart Object layers clearly. In larger documents, names such as sky, subject and logo make it much easier to find the right layer later when a client asks for a change.
FAQ
Do Smart Objects make files larger?
Often yes, since original data is embedded. Weigh the flexibility against storage.
Can I use them for templates?
Yes. Replace Contents lets you swap an image in a design and keep the same sizing and effects.
The Short Version
Convert layers to Smart Objects when you may resize or filter them later. Keep an eye on file size, and rasterize only when you are done.
