How to Repair a Corrupted PDF Online
Learn how to fix a damaged PDF file with a free online tool that works in your browser.
Published 2026-09-06
A PDF that won't open or shows errors can stop your work. The tool described here repairs corrupted PDF files directly in your browser. It is free, requires no registration, and works on Windows, macOS, and Linux.
What the Tool Does
The tool attempts to rebuild the internal structure of a damaged PDF. It processes the file on a server, so the file does travel to that server for repair. After processing, you download the repaired version.
How to Repair a PDF Step by Step
- Open the repair tool page on totalpdfkit.com.
- Drag your corrupted PDF file into the designated area, or click to select it from your device.
- Wait for the upload and repair process to finish. The time depends on the file size and your connection.
- When the repair completes, a download link appears. Click it to save the repaired PDF to your device.
No account is needed. You can use the tool as many times as you want.
When to Use This Tool
Use the repair tool when you see any of these signs:
- The PDF does not open in your usual viewer.
- An error message says the file is damaged or corrupted.
- The file was downloaded incompletely from email or a website.
- The PDF was created by a program that crashed during saving.
A repaired file may still lose some elements, such as images or fonts, if the original data is missing. The tool works best when the damage is minor, like a broken cross-reference table or a truncated file.
When Not to Use This Tool
Do not use the repair tool for these cases:
- The file is not a PDF at all (for example, a renamed .doc file). The tool cannot convert it.
- The PDF is password-protected. The repair tool does not remove passwords.
- The file is severely damaged with most of its data missing. In that case, the repair may not recover the content.
If the repair fails, try downloading the file again from the original source. Sometimes a fresh download solves the problem.
