What it does
Slazzer offers background removal, bulk image editing and an API, with paint/erase and background choices in its web workflow.
Upload a product photo, refine with paint/erase and choose a background image or colour before selecting preview or HD output. JPG/JPEG/PNG inputs can be 12 MB and 25 megapixels; larger resolution is resized. Website previews are free, while API previews up to 0.25 megapixels cost 0.20 credit and HD uses one. The Free plan's two credits are not described as monthly. Subscription credits roll over up to six times the allowance while active; top-ups last two years.
Strengths
- Paint/erase refinement controls
- Bulk and API workflows
Watch out for
