Before any feature works, finish this one-time setup.

大约需要三分钟。

Here is what the first week looked like for me:

现在让我们一步一步来。

第一步：创建您的帐户

Go to the pdfFiller website and click Start Free Trial.

pdfFiller requires an account before you can upload documents.

✓ 检查点： 检查你的 收件箱 用于确认邮件。

步骤二：打开仪表盘

pdfFiller runs in any browser, so you never install software.

Mobile and 苹果 users get the same editor with no additional software needed.

这就是它的样子：

✓ 检查点： You should land on the Dashboard with an Add New button.

以下是使用步骤。

步骤 1：上传您的文件

Click Add New on the Dashboard.

You can edit PDF online from any device with a browser.

这就是它的样子：

✓ 检查点： The text field turns editable with a blinking cursor.

Step 3: Save Your Work

Click Done, then save or download the finished PDF.

如何使用pdfFiller电子签名

电子签名 lets you sign documents and collect signatures from multiple recipients.

以下是使用步骤。

第一步：创建您的签名

Open the Sign tool in the editor toolbar.

You can type it, upload an image, or easily draw it with a mouse.

第二步：签名

Drag your signature onto the right spot in the document.

这就是它的样子：

✓ 检查点： Your signature sits inside the document, not on a separate layer.

步骤三：送交签字

Use SendToSign to invite others by email or link.

这 审计 trail records every view and every signature with a timestamp.

How to Markup PDFs in pdfFiller

标记 PDF lets you highlight, comment, and leave notes on static PDFs.

以下是使用步骤。

步骤 1：打开标记工具

Pick the highlighter, pen, or sticky note icon.

Step 2: Mark the Page

Drag across the text you want to flag.

Sticky notes work well for questions your team needs to answer.

这就是它的样子：

✓ 检查点： Your highlights show in the right sidebar as a comment list.

Step 3: Share the Marked File

Send the link or download the annotated copy.

如何使用 pdfFiller 将 PDF 转换为 Word

PDF 转 Word lets you convert PDF files into editable Word documents.

以下是使用步骤。

Choose PDF to Word from the tools menu.

Step 2: Upload and Convert

Drop in your file and press Convert.

Most files finish in under a minute.

这就是它的样子：

Pick every page or just the ones you need.

Each page becomes its own image file.

这就是它的样子：

✓ 检查点： The page count matches the number of images produced.

Step 3: Download the Images

Grab the ZIP file or single image.

如何使用 pdfFiller 将 Word 文档转换为 PDF

Word 转 PDF lets you convert Word files into fixed PDFs that keep their layout.

以下是使用步骤。

Step 1: Upload the Document

Select Word to PDF and add your .docx file.

Step 2: Check the Preview

Scan the preview for broken fonts or spacing.

Fix the source file if anything looks off, then convert again.

这就是它的样子：

✓ 检查点： Page breaks land exactly where they did in Word.

Step 3: Save or Send

Download it or send it straight for signatures.

如何使用 pdfFiller 将 JPEG 转换为 PDF

JPEG 转 PDF lets you merge photos and phone scans into one PDF document.

以下是使用步骤。

如何使用pdfFiller表单生成器

形式 建造者 lets you create fillable PDF forms people can complete online.

Add text fields, check boxes, dropdowns, and signature fields.

这就是它的样子：

✓ 检查点： Each field shows a blue outline in the editor.

Conditional logic hides fields until an earlier answer triggers them.

Filling the form then takes seconds for whoever receives your link.

保护 PDF lets you password-protect files and redact sensitive data.

以下是使用步骤。

步骤 1：打开安全设置

Choose Protect PDF from the tools panel.

步骤二：设置密码

Type a password and confirm it.

You can also store the file in an encrypted folder.

这就是它的样子：

✓ 检查点： A small lock icon appears next to the file name.

Step 3: Redact Sensitive Details

Use the redaction tool to black out private data.

Redaction removes the text underneath, unlike a plain black box.

pdfFiller 专业技巧和快捷键

After eight months of daily editing, these habits enhance my speed the most.

大多数人错过的隐藏功能

• Camera scanning: Snap pages with your phone and upload them straight into the PDF editor.
• Reusable templates: Save a finished form as a template, and save time on recurring contracts.
• Page manager: Rotate, duplicate, or delete pages without touching a separate merge tool.

pdfFiller常见错误及避免方法

Mistake #1: Typing over text instead of editing it

Mistake #2: Treating a black box as redaction

Mistake #3: Emailing forms instead of sharing a link

pdfFiller故障排除

Problem: Text won’t change when I click it

原因： The page is a scan, so the words are really an image.

使固定： Run the file through PDF to Word, edit there, then convert back.

Problem: My signature looks blurry

原因： The uploaded signature image was too small.

使固定： Draw it in the editor instead, or upload a 600px-wide transparent PNG.

Problem: A recipient can’t open the file

原因： The PDF is password-protected or the share link expired.

使固定： Reissue the link and send the password through a separate channel.
