DjVu Inspector

Inspect page dimensions, resolution, document structure, hidden text, annotations, thumbnails, and image layers without installing a DjVu reader.

Private results · no network lookup · no quality reduction · files up to 1 GB

Rights and privacy reminder: Process only documents you are allowed to use. Hidden text, annotations, and scans can contain private or copyrighted material. Results stay in the uploader’s private job and are served as no-store attachments under the existing retention period.

What the DjVu toolkit does

Bounded inspection

Reports page count, native dimensions, DPI and gamma when exposed, bundled structure, hidden text, annotations, thumbnails, and foreground, background, and mask layers.

Source-derived text

Text accuracy and language come entirely from the uploaded source. Convertr does not improve, translate, mutate, or send extracted text upstream.

Native page rendering

Selected pages are decoded by the pinned ddjvu build at their full native dimensions. Unsafe expansion fails explicitly instead of truncating or downscaling output.

Indirect DjVu documents with unresolved component references are rejected. The toolkit never follows component URLs, exposes component identifiers, accepts command scripts, or offers crop and quality switches.

DjVu Inspector

Inspect the bounded structure and native page properties of a self-contained DjVu document.

การเข้าสู่ระบบ
One signature-verified .djvu or .djv file within the 1 GB upload limit.
การออก
A private page and layer report.
ข้อ จํากัด จริง
Indirect component documents are rejected, and unavailable fields are reported as absent rather than inferred.
ความลับและการจัดการข้อมูล
one signature-verified .djvu or .djv file within the 1 GB upload limit is uploaded to a compatible Convertr worker only after you start the operation. Processing is automated, and temporary source and result files are deleted automatically after processing rather than retained as permanent storage.

วิธีการใช้เครื่องมือนี้

  1. Choose one signature-verified .djvu or .djv file within the 1 GB upload limit and wait for the page to validate it.
  2. กําหนดตัวเลือกการส่งออกหรือตรวจสอบที่พร้อมใช้งานแล้วเริ่มประมวลผล
  3. Review the reported result and download a private page and layer report before the temporary link expires.

โหมดความล้มเหลวทั่วไป

Malformed chunks, unsafe decompression, unresolved components, missing tools, or workspace exhaustion produce explicit failures.
