Can I fix error 14 without losing content?

Yes, if the damage is limited to the file's structure and not the content itself, rebuilding the PDF can recover all readable pages and objects without data loss.

Why does the error only appear on some pages?

Numbered errors like 14, 110, and 135 occur when specific pages or objects are corrupted while the rest of the file remains intact. The PDF opens because the overall structure is valid, but damaged sections fail to render.

Will updating Acrobat Reader fix error 135?

Updating can resolve error 135 if the root cause is a software bug or outdated decoder. If the file itself is damaged, updating alone will not help, and you will need to repair the file.

Is it safe to use online PDF repair services?

Most reputable services process files temporarily and do not store them. Always check the site's privacy policy before uploading sensitive documents. For maximum security, use a local desktop tool.

Fix "There Was a Problem Reading This Document" (14, 110)

When you see the message there was a problem reading this document in Adobe Acrobat or Reader, the full error often includes a number in parentheses, such as (14), (110), or (135). Unlike errors that prevent a file from opening at all, these numbered errors let the PDF partially open, but some pages or objects fail to display. What follows explains what causes these errors and walks through both reader-side and file-side fixes so you can get your document back.

What the Numbered Error Means

Reader and Acrobat display messages like There was an error processing a page. There was a problem reading this document (14). The numbers 14, 110, and 135 are error codes that point to specific types of damage or corruption inside the PDF. Error 14 signals a missing or broken cross-reference table. Errors 110 and 135 relate to page content objects that are missing, compressed incorrectly, or otherwise unreadable. The rest of the file structure stays intact, so the document partly opens. Affected pages show blank areas, garbled text, or fail to render.

Check Whether the Reader or the File is at Fault

Before making changes, determine if the problem is with your software or the PDF itself. Open the same file in a different viewer. A web browser works. Chrome, Edge, and Firefox all render PDFs. If the document displays correctly there, the issue is likely with your Reader installation. If the same errors appear in the browser, the PDF file is corrupted.

Reader-Side Fixes

Update the Software

Outdated software causes compatibility errors. In Reader, go to Help > Check for Updates. Install any available updates. Restart the program and reopen the PDF.

Repair the Installation (Windows)

If updating does not help, use the built-in repair tool. On Windows, go to Help > Repair Installation. This replaces damaged program files without affecting your settings. After the repair completes, restart the application and try the document again.

These steps resolve many reader-side issues, especially when other programs open the file without errors.

File-Side Fixes

Obtain a Fresh Copy

If the PDF came from a download, email attachment, or cloud storage, the original file may have been corrupted during transfer. Delete the copy you have. Download or request a new one from the source. Open the fresh copy immediately.

Rebuild the PDF Structure

When the file itself is damaged, the error often results from broken internal references. Rebuilding the PDF structure from recoverable objects clears errors 14, 110, and 135. This process extracts readable content (text, images, pages) from the corrupted file and assembles them into a new, clean PDF. Specialized tools perform this reconstruction automatically, preserving as much of the original document as possible.

Step-by-Step Recovery Process

Try a different viewer first. Open the PDF in a web browser to confirm the file is damaged. If it opens fine, skip to the reader-side fixes above.
Get a fresh copy. If the file is from an email or download, obtain a new version before attempting recovery.
Rebuild the PDF. Use a recovery service or tool that reconstructs the document from undamaged objects. This step targets the specific structure errors that cause numbered reading errors.
Open the rebuilt PDF. After recovery, open the new file in Reader. Test all pages to ensure the error is gone.

If the recovery succeeds, the document opens fully without the error message. If the error persists, the damage may be too extensive for automated repair.

When to Use an Online Recovery Tool

If you do not have access to desktop PDF repair software, an online service can rebuild the file structure from your corrupted PDF. Sites like repairpdffile.net let you upload the damaged file and receive a recovered version. This approach works when the file is too large to email or when you need a quick fix without installing software.

Preventing Future Errors

Save PDFs from trusted sources and avoid interrupting downloads.
Keep Reader updated to minimize compatibility issues.
If you frequently work with PDFs, use the Repair Installation option periodically.
Back up important PDFs to avoid losing data if corruption occurs.
