Technical Architecture

Universal PDF Conversion Engine

DocInspector utilizes isolated headless office environments to convert text, spreadsheets, and graphics into standardized PDF documents.

1 Excel Auto-Scaling & Layouts

Converting spreadsheets to PDF often results in broken layouts or split columns. Our engine applies intelligent auto-scaling, 'Fit-to-Page' widths, and landscape rotations to ensure tables remain fully readable on standard pages.

2 Image Merging (Many-to-One)

Convert images (JPEG, PNG, WEBP) to PDF. You can choose to convert each image to a separate PDF page, or merge multiple images into a single, multi-page PDF document in alphabetical order.

3 Headless Office Rendering

Document conversion runs in sandboxed environments, converting complex layouts (DOCX, PPTX, ODT) while maintaining fonts, paragraphs, and embedded tables precisely as they appear in the source application.

Batch Word, Excel & Image PDF Converter

📘 Detailed Technical Guide

Convert Office documents and images to PDF online. Under the conversion settings panel, configure Excel layouts (Fit Columns, Fit Sheet, No Scaling) and Image Modes (1-to-1 or Merge to single PDF). Process entire folders while maintaining structural layout. Combine conversion with watermarking, sanitizing, or password protection in one pass.

❓ Frequently Asked Questions

❓ Do converted Excel sheets preserve formatting?

Yes. By selecting the 'Fit Columns to Width' option, wide tables are scaled proportionally to fit the PDF boundaries without clipping content.

❓ Can I merge mixed file types into one PDF?

Files of the same or different formats are converted in batch. Mixed images can be combined into one PDF, while Office documents are converted to individual PDFs in the same output folder.
