What is Slazzer?
Slazzer is an online image tool that started with automatic background removal. Officially, it can remove the background 100% automatically in a few seconds. Its positioning goes far beyond "removing the background from a single image": focusing on e-commerce, photography, advertising and other scenarios, the platform also offers a set of small tools such as AI upscaling, enhancement, light adjustment, shadow generation, sky replacement, and old photo coloring. It has extended the same set of capabilities to desktop clients, mobile apps, and developer APIs. It has been doing this one small thing for years, excelling in speed and stability. Most operations can be done on the web version, and only heavy users need to install the client.
Who is it for?
- E-commerce operations staff and graphic designers who need to batch-process supplier images into white-background main images every day.
- For second-hand trading, real estate and car sales, quickly retouch the product and scene photos to make them clean.
- Independent photographers who perform unified upscaling and light enhancement before delivering the final photos.
- Teams creating product catalogs and lookbooks that need to batch-produce images in accordance with a uniform white background specification.
- Developers and small teams integrate background removal into their own listing or design systems via APIs.
Key features
6Automatic Background Removal
Upload an image to automatically separate the subject from the background. The official emphasizes edge quality, striving to retain details when processing hair, translucent objects, and fine strands. It claims no manual selection is needed, with results ready in a few seconds.
AI Upscaling
Performs super-resolution on low-resolution materials, suitable for displaying blurry images received from suppliers on detail pages or large screens, eliminating the cost of reshooting. The upscaled images will have cleaner edges after being matting-processed again.
AI Enhancement & Light Correction
One-click adjustment of exposure, contrast, and color tones. The official states that the process is completed within a few seconds, eliminating the need to open additional image editing software and work through layers. It also makes it easier to unify the color tones of the same batch of images.
AI Shadow Generation
Adds a drop shadow to the cutout subject, ensuring the composite image doesn't look like it's floating on the background. The realism of product images largely depends on this step, and the shadow direction must match the light in the original image.
Replace Sky & Colorize
Can replace the sky in photos and colorize black-and-white old photos, applicable to real estate, car and family photos, and can also create retro-style covers.
Catalog-based workflow & multi-platform support
The official team has also developed a batch processing solution for food, grocery, and furniture catalogs, and provides desktop clients for Windows, Mac, and Linux, Android and iOS apps, as well as APIs for developers.
How to use Slazzer
- First try the most difficult image on the web version, such as hair, sheer clothing or a glass, and check if the edges are sufficient before deciding to pay.
- The free web version only processes one image at a time.
- for batch processing needs, using the desktop client or API is more time-efficient and also avoids queues on the web side.
- After cutting out the image, adding shadows and adjusting the light can significantly enhance the realism of the composite compared to simply refining the cutout edges.
- Save the cutout images as transparent PNGs before compositing.
- making direct edits on images with backgrounds will leave white edges.
- Confirm portrait authorization before processing portrait and customer materials.
- the scope of commercial use is subject to the official terms.
- the platform charges by points, and the free quota may be adjusted.
- Check the pricing page before long-term use, and don’t wait until running batch processing to find the quota is insufficient.
