Document Could Not Be Processed by OCR in Eve

Last updated: March 10, 2026

Overview

This article resolves the "Document could not be processed by OCR" error that appears when Eve cannot load a PDF file. This error occurs when a PDF is corrupted, password-protected, or encrypted in a way that prevents Eve from reading it, even if the file opens normally in Adobe Acrobat or Preview.

Before You Start — Diagnosis

Confirm the following before attempting any fixes:

  • The PDF displays the "Document could not be processed by OCR" error message when uploaded to Eve

  • The PDF opens successfully in a local PDF viewer like Adobe Acrobat or Preview

  • You have access to PDF editing software (Adobe Acrobat, Preview, or similar tools)

  • You know whether the PDF is password-protected or encrypted

Fixes

Possible Cause: Minor PDF Corruption

Cause: The PDF file structure contains minor corruption or formatting errors that prevent Eve from parsing it, even though some PDF viewers can display it using built-in error correction.

Steps:

  1. Open the corrupted PDF in Adobe Acrobat (not Adobe Acrobat Reader)

  2. Go to File > Save As

  3. Save the file with a new name

  4. Upload the newly saved PDF to Eve

Expected Outcome: The PDF uploads successfully and Eve processes it without displaying the OCR error.

Possible Cause: Password Protection or Encryption

Cause: The PDF is password-protected or encrypted, which blocks Eve from accessing the file content for OCR processing.

Steps:

  1. Open the PDF in Adobe Acrobat or a similar PDF editing tool

  2. Locate the security settings (usually under File > Properties > Security)

  3. Remove the password or encryption settings

  4. Save the unprotected PDF

  5. Upload the file to Eve

Expected Outcome: Eve can now read the PDF and the OCR error no longer appears.

Possible Cause: PDF Format Incompatibility

Cause: The PDF was created using a format or structure that Eve cannot parse, even though it displays correctly in some viewers.

Steps:

  1. Open the PDF in Adobe Acrobat, Preview, or another PDF viewer

  2. Use the Print function and select "Print to PDF" or "Save as PDF" as the destination

  3. Save the newly printed PDF with a new filename

  4. Alternatively, convert the PDF to Word format using Adobe Acrobat or an online converter, then convert it back to PDF

  5. Upload the converted PDF to Eve

Expected Outcome: The newly converted PDF uploads and processes successfully in Eve.

Possible Cause: Corruption in Specific Pages

Cause: Only certain pages of the PDF are corrupted, but the corruption affects Eve's ability to process the entire document.

Steps:

  1. Open the PDF in Adobe Acrobat or a PDF editor

  2. Identify and extract only the pages you need for Eve

  3. Create a new PDF containing only those extracted pages

  4. Upload the rebuilt PDF to Eve

Expected Outcome: The rebuilt PDF with only necessary pages uploads successfully without the OCR error.

Possible Cause: Corruption from Original Creation Tool

Cause: The software used to create the PDF (such as redaction software or document management tools) is faulty or misconfigured and outputs corrupted PDFs consistently.

Steps:

  1. Identify the software or tool that created the original PDF

  2. Contact that tool's vendor to report the issue and request support

  3. Check for software updates or configuration settings that may resolve the corruption

  4. If possible, use a different tool or export method to create the PDF

  5. Upload the newly created PDF to Eve

Expected Outcome: PDFs created with the corrected tool or method upload successfully to Eve without OCR errors.
