Can ZipPDF convert Images, Text, Word (.docx), and PDFs inside a ZIP into one file?

Yes, absolutely. ZipPDF is the ultimate client-side multi-format converter. It extracts JPG, PNG, WebP, BMP, and GIF images, Microsoft Word (.docx) documents, existing PDF files, and plain text (.txt, .md) from any ZIP or CBZ archive and compiles them into a single, cohesive PDF document with zero server uploads and no API dependencies.

How are Word (.docx) documents and existing PDFs processed within the ZIP?

Word (.docx) files are parsed locally using Mammoth, converted into structured clean HTML, rendered at high DPI with html2canvas, and dynamically sliced into formatted PDF pages that fit your selected page size. Existing PDF documents inside the archive are merged using pdf-lib vector-level page copying (copyPages), which preserves 100% of the vector text, annotations, and original sharpness without raster degradation.

Does ZipPDF support nested folders inside the ZIP archive?

Yes! ZipPDF recursively extracts all files inside nested subdirectories (e.g. "Reports/Q1/summary.docx", "Photos/Event/photo1.jpg"). By default, files are sorted alphabetically respecting folder hierarchy, and you can freely reorder any file via drag-and-drop or reverse the sequence in Step 2.

Are there any archive size limits or file size quotas?

No artificial limits exist. ZipPDF operates with zero server quotas, zero paywalls, and zero cloud transfer bottlenecks. Processing capacity is governed solely by your device’s available RAM. Modern laptops and smartphones can easily handle archives containing hundreds of megabytes or gigabytes of images and documents.

What happens if my ZIP archive contains unsupported files like videos or audio?

ZipPDF automatically filters out OS metadata files (such as __MACOSX, .DS_Store, and thumbs.db) silently. Any unsupported files (such as .mp4, .mp3, or .exe) are skipped gracefully without aborting the conversion. Step 2 shows a clear warning toast displaying the exact count of skipped files so you remain fully informed.

Is my data completely private and safe for confidential or legal files?

100% yes. No file data ever leaves your browser sandbox. Unlike traditional online converters that upload your confidential archives to remote cloud servers, ZipPDF executes entirely on your device using WebAssembly, TypedArrays, and HTML5 Canvas. Files never leave your device, which helps you meet GDPR and HIPAA privacy requirements.

How do I download my final merged PDF file?

In Step 3, once the progress indicator completes ("Merging PDFs...", "Rendering Word docs...", etc.), a massive "Download Final PDF" button appears. Clicking it triggers an immediate, direct download to your device without slow preview iframes or ad redirects.

What page sizes and orientations can I customize?

ZipPDF provides comprehensive enterprise page geometry controls in Step 2. You can select ISO A4 (210 × 297 mm), North American US Letter (8.5 × 11 in), or US Legal (8.5 × 14 in). Orientation controls allow Auto aspect matching, Always Portrait, or Always Landscape, alongside fine margins (None, Narrow, Standard, Wide).
