How to Convert, Merge, and Secure Documents with Solid PDF Creator PlusSolid PDF Creator Plus is a full-featured PDF toolkit designed to help individuals and businesses convert files to PDF, merge multiple documents, and apply security settings with minimal effort. This guide walks you through the core workflows—conversion, merging, and securing—plus helpful tips and best practices to get consistent, professional results.
What Solid PDF Creator Plus does best
Solid PDF Creator Plus focuses on three common PDF needs:
- Convert many file types (Word, Excel, PowerPoint, images, web pages) into high-quality PDFs.
- Merge multiple files and different formats into a single, well-ordered PDF.
- Secure PDFs with passwords, permissions, and digital signatures to control access and protect content.
System requirements and installation
Before starting, ensure your system meets the app’s requirements (Windows is the primary platform). Typical needs:
- Windows 10 or later (64-bit recommended)
- 2+ GB RAM (4 GB+ recommended for large files)
- Free disk space for temporary files (500 MB+)
- Microsoft Office integration works best with Office installed
Installation is straightforward: download the installer from the official site, run it, and follow prompts. During setup you can enable virtual printer integration, which provides a convenient “Print to PDF” option from most applications.
Converting documents to PDF
Using the app interface
- Open Solid PDF Creator Plus.
- Choose the “Create PDF” or “Convert” option.
- Add files by drag-and-drop or the Add Files button. Supported inputs include:
- Microsoft Word (.doc, .docx)
- Excel (.xls, .xlsx)
- PowerPoint (.ppt, .pptx)
- Images (.jpg, .png, .tiff)
- HTML and web pages
- Adjust conversion settings:
- Output quality (screen, print, high quality)
- PDF/A for archiving (if long-term preservation is needed)
- OCR options for scanned images (select language and accuracy level)
- Click Convert and choose output folder and filename.
Tips:
- For documents that need selectable/searchable text, enable OCR when converting scanned PDFs or images.
- If converting complex layouts (tables, multi-column text), use the “Advanced” settings to preserve layout and fonts.
Using the virtual printer (“Print to PDF”)
- From any application (e.g., Word), choose Print.
- Select “Solid PDF Creator” as the printer.
- Configure page settings and click Print.
- The virtual printer opens a dialog to adjust PDF options before saving.
This method is quick for single documents or apps without native export options.
Merging multiple documents
Basic merge
- Open Solid PDF Creator Plus and select “Merge” or “Combine Files.”
- Add files in the order you want them to appear. You can mix formats—Word, images, Excel sheets, and existing PDFs.
- Reorder files using drag-and-drop. Expand page ranges if you only need specific pages from a document.
- Choose merge options:
- Add bookmarks (based on file names or headings)
- Insert a table of contents
- Control page numbering (restart numbering or continue)
- Click Merge and save the combined PDF.
Advanced merging workflows
- Extract specific pages: import the file, specify page ranges (e.g., 1–3, 6), then merge.
- Merge with headers/footers: apply consistent headers/footers (title, date, page number) to the entire merged PDF.
- Preserve or flatten annotations: decide whether to keep comments and markups editable or flatten them into the content.
Best practices:
- Standardize page sizes and orientations beforehand to avoid inconsistent layouts.
- Use bookmarks or a table of contents if the merged file will be long or used by others.
Securing your PDF files
Password protection
- Open the PDF in Solid PDF Creator Plus or set security during creation.
- Go to Security or Protection settings.
- Set an “Open” password (required to open the document) for highest protection.
- Optionally set permissions password to restrict actions:
- Prevent printing
- Prevent copying or extracting text and images
- Prevent editing or changing annotations
- Choose encryption level (e.g., 128-bit AES or higher if available).
Notes:
- Use a strong, memorable password and share it securely (not via unsecured email).
- Permissions passwords differ from the open password: the permissions password is needed to change restrictions later.
Digital signatures and certificates
- Select the Sign tool to add a visible or invisible digital signature.
- Use a certificate-based signature (from a trusted certificate authority or an internal certificate) to prove authorship and integrity.
- After signing, you can lock the document so further edits invalidate the signature.
When to use:
- Contracts, invoices, legal documents where non-repudiation and tamper-evidence are required.
Redaction and content removal
- Use redaction tools to permanently remove sensitive text or images.
- Apply redaction marks, then choose “Apply Redactions” to overwrite and remove content.
- Verify metadata and hidden data (comments, form fields, document properties) are cleaned before sharing.
Important: Redaction is permanent—keep an original copy if you need the full content later.
Accessibility and compliance options
- Create PDF/A for archiving or PDF/UA for accessibility compliance when needed.
- Add document structure (tags, headings) to improve screen reader compatibility.
- Run accessibility checks if the file will be used by people requiring assistive technologies.
Automation and batch processing
Solid PDF Creator Plus typically offers batch conversion and automation:
- Convert entire folders of files into PDFs in one run.
- Apply the same security settings to multiple files.
- Use command-line or scripting (if provided) to integrate with workflows or document management systems.
Example batch use cases:
- Monthly invoicing folder → convert all invoices to PDF/A and add a watermark.
- HR onboarding documents → merge forms and secure with a permissions password.
Troubleshooting common issues
- Mixed fonts or layout shifts: embed fonts during conversion and enable layout-preservation options.
- Large file sizes after merging: compress images, downsample high-resolution images, or use a reduced-quality output setting.
- OCR accuracy problems: increase DPI when scanning (300–600 DPI recommended) and select the correct OCR language.
Tips for professional outputs
- Use consistent page size, margins, and fonts before converting to minimize layout fixes.
- Add metadata (title, author, keywords) to improve searchability and organization.
- Apply watermarks or headers with company name on drafts; remove or change for final versions.
- Keep an original editable source file and export a finalized PDF for distribution.
Solid PDF Creator Plus consolidates conversion, combining, and security tools into a single workflow-friendly application, making it practical for individuals and teams who manage many document types. Follow the steps above to convert accurately, merge cleanly, and secure confidently.
