PDFgear is for people who are okay with using a free PDF editor that offers basic and some advanced features.

OCR and PDF Conversion

Working with scanned documents is common these days, hence it is important that the PDF editor you work with has OCR and conversion capabilities. All three tools offer both these capabilities. However, they differ in speed, accuracy, and reliability.

Security, Redaction, and Privacy

As PDF documents become increasingly popular, they are used by everyone from business houses to professionals, advocates, and students. This makes it more important than ever to protect these documents. This can be done by adding passwords, setting restriction permissions, redacting sensitive information, digitally signing documents, and more. Here’s how the three editors handle PDF security:

Systweak PDF Editor, being an offline editing tool, focuses on offline-first security. For users working with confidential files who wish to keep them secure without uploading, this is the perfect solution. Using this tool, you can not only password-protect the file but can also set restriction permissions, redact sensitive information, and digitally sign documents. Here’s what the tool offers:

• Password-protect PDFs with strong 128/256-bit encryption.
• Set permissions to restrict printing, copying, or editing.
• Permanently redact text or images (cannot be undone once saved).
• Remove passwords if you have access to the protected file.
• Search and redact information from the complete document.
• Clear metadata to avoid being tracked.
• Protect or unprotect multiple PDFs.
• Add digital signature certificates and secure documents.

UPDF is a combination of offline and online tools. You can use it to redact sensitive information, add a password to your PDF, set a permission password, sync files via UPDF cloud, ensuring both privacy and collaboration. The tool allows you to:

• Encrypt PDFs with open and permission-based passwords.
• Redact text or images permanently.
• Store and sync files with UPDF Cloud (10–100GB, encrypted).
• Redact specific terms across the file.
• Access and protect documents securely on desktop and mobile.
• Remove hidden and metadata from the document.
• Redact pages.
• Redact with overlay or custom text and color.

PDFgear is a free PDF editing tool that allows you to set and remove a password to the document. The tool provides basic security functionality, which is good for a free tool. However, if you are looking for redaction, batch protect, and unprotect, adding digital signatures like Systweak PDF, you will be disappointed. The tool offers the following features:

• Basic security only has a Password dialog in Tools.
• Basic encryption level.
• An offline tool to protect documents.
• No ads or hidden data use policy.
• Lightweight password security without complexity

Summary- Systweak PDF Editor is an offline PDF Editor that offers strong encryption, owner permissions, permanent redaction, digitally signing documents, metadata removal, and other security features. UPDF is a combination of offline and encrypted cloud storage. It offers password protection and a redaction tool. PDFgear is a 100% free tool that allows you to add a password to your document to lock it and avoid unauthorized access.

Batch Processing and Advanced Tools

Handling multiple PDFs, editing, and managing them is not easy. This is when tools that offer batch processing are required. Here’s how Systweak PDF Editor, UPDF, and PDFgear compare when it comes to batch processing and some other advanced tools.

Systweak PDF Editor is an excellent and powerful PDF editor that allows you to perform batch conversion, creation, compression, merging, protection, unprotect, and even batch OCR on a set of scanned PDFs. You can select as many files as you want and perform batch operations on them. The interface is easy to use, and you can pick the batch tool from the Tools tab under Batch Process.

During our test, the tool was able to quickly process more than 50 files, and the output of each file was flawless. Not only does this tool let you set preset passwords to unlock PDFs, which helps save time and increase productivity.

UPDF is another similar tool that allows you to batch process PDF files. You can convert, create, merge, protect, and print multiple files at once. This helps save valuable time, maintain document consistency, and reduce the likelihood of errors. Additionally, you can easily manage documents by converting scanned PDFs in batches, which reduces the risk of losing paper documents.

During our test, UPDF performed well and was able to perform batch processing without any issues.

PDFgear doesn’t offer many batch processing options. Using PDFgear, you can batch convert, compress, and print PDF files. For a free PDF editor, it is good. However, the absence of a unified batch manager makes tasks like batch protection, OCR, and creation more challenging.

Advanced Tools

Beyond these editing, annotations, and batch processing features, these professional-grade PDF editor also offers some extra features that make them stand apart from the crowd. Here’s how the three compare:

Systweak PDF Editor offers:

• A PDF repair tool that helps fix corrupted PDF files without any external plug in.
