DeepL 靠”译得像人”在机器翻译市场撕开缺口：商务邮件、正式文档的译文自然度长期领先，整篇 Word/PDF 翻译保留排版的功能是职场刚需，API 也被大量产品集成。
支持语种数量不如谷歌，冷门语言覆盖有限；文学与强专业领域仍需人工校对。免费档有字符与文档数限制，Pro 订阅按月付费。
选型建议：涉外商务、文档翻译重度用户值得订阅；偶尔查词用免费网页版就够。

常见问题
DeepL 比谷歌翻译好在哪？
译文更"像人写的"：语气、断句、用词更适合商务与正式文档，尤其是欧洲语言之间；中文英译质量也稳。
免费能用多少？
网页版免费但有字符/文档数限制，Pro 解除限制并开放 API，价格以官网为准。
能翻译整份 Word/PDF 吗？
能，且保留原文排版，这是职场高频刚需。
