剧本 PDF 加水印
在浏览器里给剧本 PDF 加水印，不上传
这个免费工具让你在把稿子发给制片、演员或比赛读者之前，先在浏览器里给剧本 PDF 加上水印。载入 PDF，设好文字、位置和透明度，下载盖好章的副本；或者切到批量模式，为每位收件人各生成一份带名字的副本。全程没有任何内容被上传。
剧本上的水印做两件事：它让人不敢随手转发；而万一稿子外流，那个带名字的印记会告诉你走出去的是哪一份。这也是制片厂和经纪公司给阅读用副本盖上姓名和日期的原因。专业的做法很具体：低透明度（10% 到 40%）、灰色或红色都要压住、斜穿页面或贴在边缘，绝不能重到把下面的对白挡住。
PDF 完全在你的浏览器里用一个开源 PDF 库处理。你的剧本从不会被上传到任何服务器，收件人姓名也不会离开这个页面。

百分之百私密：PDF 在这个标签页里加水印，从不上传。
在上面载入一个剧本 PDF，才能开始加水印。
工作原理
工具把你的 PDF 载入内存，嵌入 Helvetica 字体，然后按你选的位置在每一页上绘制水印文字：斜向选项会绕页面中心旋转 45 度，或者在靠近上下边缘处居中。透明度被限制在 10% 到 40% 之间，让印记既看得见又不遮住剧本。批量模式下，同一套盖章会按收件人逐行跑一遍，生成分别命名的文件，每份都有自己的下载按钮。有密码保护的 PDF 无法修改，请先去掉密码。
为什么发出去之前要给剧本 PDF 加水印
写作者对「为了加个水印，把一部还没面世的剧本传到某个随便的转换网站」这件事心里发怵，这很有道理。那些网站大多在自己的服务器上处理文件，也就是说你还没拍出来的剧本，躺在了别人的存储里。这个工具就是为这份担心而存在：它在浏览器里给 PDF 加水印，保护这一步于是不会变成暴露那一步。
按收件人加水印，是真实制作里的标准做法。当每位读者手上的副本都带着自己的名字时，转发一份稿子就有了代价；万一有页面出现在网上，你也知道是哪一份漏了出去。以前要给一整份收件人名单加水印，意味着在编辑器里一份份盖章；在这里，你粘一列名字，每人得到一份带名字的文件。
不过也要知道什么时候该发干净的副本。比赛、扶持计划和投稿门户通常期待一份没有水印的 PDF，在那些场合，一个太重的印记反而显得业余。直接发给制片、演员、投资方和围读时用低调的水印，正式投递时保留一份没有水印的母版。一个好的水印工具，会让盖章的那份成为一个变体，而不是你唯一的文件。
适合谁
- 把稿子发给制片的写作者 给每一份副本盖上收件人的名字，一旦某份 PDF 外流，它会指回它的来源。
- 制作统筹 一次性批量生成给剧组和演员的副本，不必在围读前一份份盖章。
- 保护热门项目的电影人 在剧本流向融资或选角谈话之前，先加上一个保密稿的印记。
Script Watermarker: the complete guide
It stamps a text watermark on every page of a screenplay PDF (diagonal, top, or bottom, at 10 to 40 percent opacity) and can batch-generate one personalized copy per recipient name, all without uploading the file anywhere.
For this workflow, the central problem is clear: unwatermarked drafts get forwarded freely, and when pages leak there is no way to tell which recipient's copy walked. Left unresolved, this creates downstream friction and slower decisions. The practical target is personalized, professionally subtle watermarked copies of a script PDF, generated in the browser so the protection step never exposes the file.
Limitation to keep in mind: A watermark deters and identifies, it does not technically prevent copying, and password-protected PDFs must have their encryption removed before they can be stamped.
Advanced workflow: Production teams keep a clean master PDF, then cut a fresh batch of per-recipient copies for each draft milestone, logging which name received which draft date so any leaked page maps to one person and one version.
Step-by-Step Workflow
- Export a clean PDF from your screenwriting app and keep it as the unwatermarked master.
- Load the PDF here, set the text, placement, opacity, and color, aiming for subtle: diagonal gray around 20 to 25 percent.
- For a group send, switch to batch mode and paste one recipient name per line to get a personalized file each.
- Download the stamped copies and send each recipient only the file carrying their own name.
Use Cases By Profile
- Writer: stamp a producer's name on the copy you send so forwarding it has a visible cost.
- Coordinator: batch-generate cast and crew copies before a table read instead of stamping files one at a time.
- Filmmaker: mark financing and casting copies of a hot project CONFIDENTIAL DRAFT before they circulate.
Common Mistakes To Avoid
- Uploading an unreleased script to a server-side watermark site, turning a protection step into an exposure step.
- Cranking opacity or size until the stamp fights the dialogue, which reads as amateur and gets copies re-requested clean.
- Sending one shared watermarked file to a whole list, which erases the per-recipient traceability that makes watermarks useful.
Professional Best Practices
- Include the draft date or version in the watermark text so a leaked page identifies both the person and the draft.
- Keep an unwatermarked master for contests and agency portals, which usually expect clean copies.
- Gray reads as standard and discreet; save red for copies where you want the confidentiality signal impossible to miss.
Treat this tool output as a decision support layer, not a replacement for authorship. Great scripts are remembered for specific choices, emotional precision, and clarity of dramatic movement. Tools help by removing noise so your energy can go where it matters: character, conflict, escalation, and payoff. If you review outcomes after each pass and keep an explicit log of accepted changes, your workflow becomes faster and more predictable from draft to draft. That consistency is exactly what professional collaborators value: fewer surprises, clearer rationale, and a script that evolves with intent.
Extended FAQ
Do watermarks actually prevent script leaks?
They deter rather than prevent. A determined leaker can retype pages, but per-recipient watermarks make casual forwarding traceable, and that accountability is what changes behavior on real productions.
Should I send agencies and contests a watermarked script?
Usually no. Contests, fellowships, and agency submission portals expect clean PDFs, and a stamp can read as distrustful in that context. Watermark direct sends to producers, actors, and financiers instead.
Where should the watermark go on a screenplay page?
Diagonal through the center is the standard for security stamps because it crosses the page without sitting on the dialogue column. Top or bottom placement suits lighter labels like a draft date.
Can a watermark be removed later?
From the stamped file, not cleanly, which is the point. For yourself, never rely on removal: keep the unwatermarked master and regenerate stamped copies whenever you need them.
Does watermarking change my PDF's formatting or page count?
No. The tool draws text onto the existing pages without reflowing anything, so the Courier layout, margins, and page count stay exactly as your screenwriting app exported them.
How many recipients can I batch watermark at once?
One PDF is generated per line in the recipients list, and processing happens locally, so the practical limit is your machine. Typical batches of 10 to 30 reader copies generate in seconds.
常见问题
用这个工具是安全的，因为它其实不是在线处理：PDF 在你的浏览器标签页里被打开和盖章，从不上传。页面加载完之后你可以断网，它照样能用。
切到批量模式，一行粘一个名字。工具会为每个人生成一份单独的 PDF，盖上那个名字（致：Jane Smith），每份都有自己带标签的下载按钮。
保持在 10% 到 40% 之间，也就是这个工具允许的范围。20% 到 25% 左右的斜向灰色是最常见的专业做法：每一页都看得见，阅读时又不碍事。
加密的 PDF 没有密码就无法修改。在你的 PDF 阅读器里打开文件，去掉密码（或者重新导出一份没有密码的），然后再载入到这里。
不会。透明度上限让印记保持半透明，斜向摆放又是斜着穿过页面，而不是压在对白栏上。你的 Courier 文字在屏幕上和纸上都依然清晰可读。
