Bg Eraser
Hard to beat on price and friction — free, no account, and 20-image batches cover small e-commerce runs. The trade-offs are an anonymous operator, no API for automation, and edge quality that will not always match paid tools on hair and fine detail.
Pros
- Genuinely free with no registration or watermarks
- Batch mode processes up to 20 files at once
- Windows and Mac desktop apps alongside the web tool
- Terms explicitly document the no-limits policy
Cons
- No public API despite the work being automation-friendly
- Operator and legal entity are not identified anywhere
- The free model could gain billing later — the terms say so
