想要免费去除照片背景？我们测试并排名了 5 款能提供专业效果且无水印或费用的工具。
Most "free photo background removers" hide real costs: watermarks on output, 720p caps, or "1 free then pay." Here are the tools that actually deliver usable free results.
| BG-Zero | remove.bg | Photoroom | Erase.bg | TinyWow | |
|---|---|---|---|---|---|
| Price | Free | 1 free, then $ | Free (watermark) | Free (low-res) | Free |
| Account | None | Required | Required | None | None |
| Upload | No (local) | Yes | Yes | Yes | Yes |
| Max Free Res | Unlimited | 25MP (1 img) | 720px | 1200px | Unlimited |
| Batch | 100 images | No | No | No | No |
| Watermark | None | None | Yes | None | None |
| Offline | Yes | No | No | No | No |
BG-Zero is the only tool with no resolution cap, no watermark, no credit system, and no sign-up. Every other tool imposes at least one of these restrictions on free users.
上传图片，让 AI 来完成工作。简单、快速、有效。
BG-Zero runs AI locally in your browser. No upload means complete privacy, and no server costs means it stays free. After the one-time 30MB model cache, it works fully offline — a feature no other tool offers.
Excellent AI quality but the "free" claim is misleading: 1 image at full resolution, then $0.25/image. Fine for a one-off passport photo, unsustainable for regular use.
Strong AI for product photos, but free exports have a watermark and 720px resolution limit. Good for testing, not for production.
Fast one-click removal. Free tier caps at ~1200px — fine for social media, not for print. No account required.
Truly unlimited free. But cloud processing uploads your photos (auto-deleted after). No batch mode. A solid backup, not a daily driver.
与云端工具不同，BG-Zero 在你的浏览器中本地处理一切。
BG-Zero、Photoroom 和 Erase.bg 的免费结果不带水印。remove.bg 免费版会添加水印。
有，只有 BG-Zero 完全在浏览器中运行，任何环节都不需要上传图片。
可以，BG-Zero 批量模式支持一次处理最多 100 张图片，完全免费。
主流工具都能产出不错的 AI 结果。BG-Zero 还额外提供手动精修功能，包括取色器、容差滑块和蒙版画笔。
即时、私密、真正免费。无需注册。
