Onison

Onison removes and replaces backgrounds on professional product photos, keeping CMYK layers intact and adding drop shadows. Transparent, white or brand colored backgrounds are supported across CMYK, RGB, RAW and TIFF files, with plans starting at $20 per month for 50 images.

Onison is a web based asset management platform whose whitespace tool targets a narrow but demanding job: stripping and replacing the background of professional product photographs. Where most background removers are trained on everyday RGB snapshots, this one is positioned for catalog and print workflows, handling white space, pre-defined brand colors and transparency as the replacement background. It also adds a drop shadow to the cut-out product, either from a preset option or one defined by the user. The feature that separates it from generic cut-out services is color space handling. Onison states the tool retains the CMYK layers of the original product image, so files prepared for print keep that separation through the process rather than being flattened into RGB. Supported input and output formats include CMYK and RGB, JPG, JPEG, PNG, TIF, TIFF, GIF, DNG (RAW) and BMP. A free testing area on the site accepts RGB JPG and PNG files; professional image format input and output are tied to a subscription. The product is aimed at ecommerce teams, studios and brand managers producing consistent product imagery at volume, particularly those whose files have to work in print as well as on the web. Beyond the remover, a subscription bundles 1 GB of disk space, unlimited uploads (standard size derivatives that discard originals are excluded), unlimited downloads under a fair usage policy, one administrative user and file sharing both publicly and inside an organization. Signup asks for a name, phone, email and a chosen subdomain, which becomes the address of the team workspace. Pricing is per month with an image allowance rather than per seat. The base $20 plan covers 50 removals and drop shadows, with top-ups at $1 per 5 images, and bulk plans advertised from 3 cents per removal for heavier volumes. Extra storage is $1 per GB per month and billing is by credit card in U.S. dollars. Buyers comparing standalone cut-out tools should weigh the print color support and the bundled asset storage against the monthly image cap.
