功能对比
Both tools edit PDFs. The real gap is what happens after the edit. Here are ten features side by side.
| 特征 | pdf填充器 | 乌干达人民国防军 |
|---|---|---|
| 起价 | 每月 8 美元 | 每年 39.99 美元 |
| 免费计划 | ❌（30天试用期） | ✅（已加水印） |
| Fillable Form Builder | ✅ | ✅（基础） |
| Built-in eSignatures | ✅ | ✅ (UPDF Sign plan) |
| AI Chat & Summaries | ❌ | ✅ |
| OCR | ❌ | ✅ |
| Offline Desktop Editing | ❌ (cloud-first) | ✅ |
| Unlimited Cloud Storage | ✅ | ❌ (10 GB) |
| HIPAA / SOC 2 Type II | ✅ | ❌ |
| 最适合 | Forms, contracts, teams | AI reading, solo editing |
1. PDF Editing
pdfFiller： You can edit PDF documents right in your browser. Add text boxes, images, company logos, and new pages in a few clicks. Changes save on their own, so you never lose work.
UPDF： UPDF edits text, images, and links much like a word processor. It runs offline on your desktop. Reviewers say it handles basic PDF editing well, but advanced tools lag behind pricier rivals.

2. eSignatures
pdfFiller： Secure eSign is part of every plan. You can sign, request signatures, and track signed documents in one place. Share a form by direct URL, and people sign without making an account.
UPDF： You can add a simple signature inside the editor. Full signing workflows need the separate UPDF Sign plan. That means a second bill if you send contracts often.
⚠️ 警告： pdfFiller’s mobile app sometimes won’t sign PDFs with odd formatting. Sign tricky files on desktop to be safe.
3. Annotation & Markup
pdfFiller： You can highlight text, add sticky notes, and leave comments. Teammates see the markup in real time. It works well for contract review.
UPDF： You can annotate PDFs with highlight, underline, and strikethrough. You can also add shapes, stamps, and comments. It’s a strong pick for solo study and reading notes.
4. File Conversion
pdfFiller： Converting files is simple. You can turn a PDF into Word docs or JPEG images and back again. It covers the basics most offices need.
The reverse direction works just as smoothly.
UPDF： You can convert PDF to Word, Excel, PPT, RTF, HTML, XML, PNG, and plain text. That’s a wider format list than pdfFiller. It’s handy if you export data often.
5. Fillable Forms & Templates
pdfFiller： This is where it wins. You can drop in fillable fields like text fields, checkboxes, and dropdowns. Save reusable templates, pre-fill data, and even collect payments through forms. For example, a clinic can turn a paper intake sheet into an online form.
UPDF： You can fill and create basic forms. There’s no huge template library. Building and sending forms at scale takes more manual work.
6. 人工智能功能
pdfFiller： pdfFiller doesn’t focus on AI chat or summaries. Its strength is 自动化 for forms and signing. You won’t ask it questions about a report.
UPDF： The UPDF AI assistant lets you chat with your PDFs. It pulls answers fast from complex files. It also summarizes, translates, and builds mind maps.
Here’s the mind map tool in action.
7. OCR & Scanned Documents
pdfFiller： pdfFiller has no OCR tool. Scanned pages stay as images. You can still sign and annotate them.
UPDF： OCR turns scans into editable, searchable PDFs. You can then extract text or edit it. That ability saves hours of retyping. Some users say OCR help from support is hard to get when it misfires.
![[2025] OCR PDF: Convert Scanned PDFs to Editable Text in Seconds!](https://www.fahimai.com/wp-content/cache/flying-press/rrD1IvcDaqo-hqdefault.jpg)
8. Page Organization
pdfFiller： You can merge, split, and compress files. Combine multiple PDF files into one, add pages, or delete pages. It all happens in the cloud.
UPDF： You can organize PDF pages by rearranging, splitting, merging, and cropping. It also lets you add bookmarks and search inside files. Several display modes make long PDF pages easier to read.
9. Security, Storage & Access
pdfFiller： It meets HIPAA, GDPR, and SOC 2 Type II. You can password-protect files and store unlimited documents. Import from cloud services like Google Drive and Dropbox in one step.
UPDF： UPDF Cloud syncs files across devices with 10 GB on paid plans. It’s compatible with Windows, Mac, iOS, and Android. But some users hit slow load times and frequent sign-outs.
⚠️ 警告： UPDF login prompts often come from browser or security software clearing saved logins. If login codes don’t arrive by email, check spam first. Even people who purchased UPDF’s perpetual license report these prompts.
10. 定价与成本
Here are all six plans side by side.
| 层级 | pdf填充器 | 乌干达人民国防军 |
|---|---|---|
| 自由的 | ❌（30天试用期） | Free version (watermarked) |
| 入口 | Basic: $8/month | UPDF Pro: $39.99/year |
| 中间 | 另加：每月 12 美元 | UPDF Sign: $69/year |
| 顶部 | Premium: $15/month | AI Assistant: $79/year |
pdfFiller： You pay more, but you get all the tools for forms, eSign, and storage in one subscription. There’s no paid add-on for signing. Yearly billing saves a lot versus monthly.
UPDF： The paid plan for editing is cheap. AI and signing are sold separately, so costs stack up. Buy only the plan you’ll actually use.
