Removing a background used to mean careful mask work in Photoshop. Today a good tool can do most of it in seconds. But "removed" and "clean" are not the same thing — edges, hair and shadows are where most cutouts fall apart.
This guide covers the workflow, the settings that matter, and how to fix the usual problems.
What "transparent" actually means
A transparent PNG keeps an alpha channel — a separate value for every pixel that says how opaque it is. That is different from painting the background white. If you need to place a product photo on a coloured banner, a dark website, or a different background later, only a real alpha channel will work.
JPG cannot store transparency. If you save a cutout as JPG, the background becomes white (or black) again. Use PNG or WebP for transparent output.
Step by step
- Open PixelCut in your browser.
- Drop your image (JPG, PNG, WebP, HEIC and others are supported).
- Pick an engine. Fast mode removes a flat, single-colour backdrop instantly. AI mode handles people, hair, pets and busy scenes.
- Check the edges. Use the Keep and Erase brushes to fix small mistakes.
- Fine-tune if needed. Adjust edge shift, feather and despill for a natural blend.
- Download PNG (or WebP for a smaller file).
Fast mode vs AI mode
| Use case | Best mode | Why |
|---|---|---|
| Product on white | Fast | Colour-based removal is exact and instant |
| Logo or screenshot | Fast | Flat background, hard edges |
| Portrait with hair | AI | Understands the subject, not just colour |
| Pet or plant | AI | Complex outlines and soft edges |
| Busy street scene | AI | Background is not a single colour |
How to get clean edges
Start with a good source
Sharp focus and reasonable lighting matter more than any slider. A blurry photo will produce a blurry cutout, and a subject that blends into the background (dark hair on a dark wall) is genuinely harder.
Do not over-feather
Feather softens the edge. A little helps hair and fabric; too much creates a glowing halo. For hard products, keep feather at zero.
Use despill on green screens
Despill removes the old background colour from semi-transparent edge pixels. It is the difference between a clean cutout and a subject with a green fringe.
Zoom in before you export
Most edge problems are invisible at fit-to-screen zoom. Check at 100% around the hair, shoulders and hands.
Common mistakes
- Exporting as JPG and losing the transparency.
- Cropping too tight — leave a little breathing room for shadows and future layouts.
- Removing the shadow entirely — a soft contact shadow often makes a product look real.
- Using a low-resolution image and scaling it up afterwards.

Where transparent PNGs are useful
- Marketplace product listings that require a plain background.
- Presentation slides and thumbnails with coloured backgrounds.
- Website hero images and cards.
- Print-on-demand designs and stickers.
- Profile pictures and team pages.
Frequently asked questions
Is the background really removed or just painted white?
Really removed. The PNG keeps an alpha channel, so you can place it on any colour and the old background will not show.
Does it work on iPhone photos?
Yes. HEIC files are supported. The AI model runs locally, so the photo is not uploaded.
Can I process several images at once?
Yes — PixelCut supports batch processing and a ZIP download.
Why does the AI model take a moment the first time?
The model (about 42 MB) is downloaded once and cached by your browser. After that, later images are much faster.
