Step 1: Drag & drop your DjVu or click to select a file.
Step 2: Auto mode analyzes your document and applies the best settings—no configuration needed.
Step 3: Download your optimized, searchable PDF.

This page focuses on high-quality DjVu → PDF conversion with automatic best settings. You can convert one DjVu at a time using this converter.

Why Converter App?

Preservation of Embedded OCR

Unlike generic converters that ignore hidden metadata and flatten pages into simple bitmaps, our engine detects the pre-existing text layer (OCR) within the source DjVu when present. We extract and migrate this layer directly into the PDF container. This ensures that the searchable text originally present in your document is retained 1:1, allowing you to copy, search, and select text exactly as intended without re-processing.

Intelligent Compression Logic

Unlike standard tools that blindly decode DjVu data—causing PDF file sizes to explode by 10x—we utilize a dynamic optimization algorithm. Our system analyzes the document structure to calculate the precise balance between data density and visual fidelity. This intelligent logic ensures the optimal balance between quality and file size, avoiding the huge, bloated files found in competitor outputs.

Private & Established

Unlike opaque web utilities that store data indefinitely, we operate on a strict 'process-and-purge' policy. Your files are transferred via secure SSL and permanently deleted from our servers immediately after conversion. We have years of experience with DjVu as the direct successor to DjVu-PDF.com—a converter that was even recommended by the inventors of the DjVu format on their website.

Frequently Asked Questions

What is a DjVu file?

DjVu is a compression format designed by AT&T Labs for high-resolution scanned documents. Unlike standard images, it separates a page into three layers (background, foreground, and mask). This allows documents to be compressed 500x–1000x smaller than standard scans while keeping text distinct and sharp.

Why is your converter better than others?

DjVu files actually contain a hidden text layer. Most other converters skip this and just take a "screenshot" of each page, creating blurry files that are impossible to search. We don't. We use Multi-Layer Extraction to surgically separate the text from the background. This preserves the original sharpness and ensures your result is fully searchable and copy-pasteable.

Will my PDF be text-searchable?

Yes, provided the original DjVu contains a text layer. We transfer the native data structure 1:1.

Note: If the original was a flat scan with no embedded OCR, the PDF will remain a flat scan.

Why is the resulting PDF larger than the DjVu?

Since DjVu is inherently more efficient than PDF, a file size increase is unavoidable. However, we avoid the massive bloat common in competitor tools. Instead of "one-size-fits-all" settings, we dynamically adjust compression parameters based on the file you submit. We calculate the unique "sweet spot" for each document to balance visual quality and file size, utilizing JBIG2 for black-and-white content to keep files manageable.

How do you handle data privacy?

We operate on a Zero-Retention architecture. Transfers are SSL-encrypted, processing is fully automated, and files are permanently deleted from our servers immediately after the conversion stream ends.

I was visiting djvu-pdf.com but arrived here. How are these sites related?

You are in the right place. This site is the official successor to djvu-pdf.com. We are the same team behind the original tool—which was recommended by the official DjVu website—but we have built this new platform to provide a faster, more modern experience. As always, the service remains completely free.
