I try to keep this online JPEG Repair Service affordable for everyone. I will try everything I can to fix your corrupt or damaged JPEG files. I can fix files that JPEG repair software can not. So even if you have tried software like Stellar JPEG repair and were unable to fix your photo, there is a more than fair chance I can repair them manually.
Your confidentiality and privacy are guaranteed, and the service is performed on a secure, private computer. If necessary, I will sign any NDA or other agreements prior to recovering data. After completing image repair I will delete all your images from my PC.
No cure, no pay!
This service is for existing JPEG files that are corrupt. So you can see them in a file browser but when you double click them they do not open at all or they do not display correctly. If you need to recover lost or deleted files from a memory card, use JPEG Recovery LAB instead.
1. Deliver your corrupt JPEG files
- Using a File Sharing Service like Dropbox or Google Drive. This is the preferred method as it is the most robust when working with larger files. Also it does not put stress on my webserver. If you have a large number of files to repair, ZIP them and upload them to your file sharing service. Sent me the URL so I can download the file. If you password protect the ZIP file, include the password.
- Sent the files by email. If you have only a few files you can email them.
- Use the File Upload form below. If you have no other options use the File Upload on this page.
Some types of damage I can only fix if I have a sample of an intact file, specially when the file does not open at all. If you can not open the JPEG at all, I need a header of an intact file. Please include a sample file, shot with the same camera using the same settings. Name the file sample.jpg so I can recognize it.
|Upload files to DiskTuna server|
Following restrictions apply: Max file size 64 MB. Accepted file extensions: ZIP, JPG and JPEG. You can only upload one file at the time. For added privacy and security you may want to use password protected ZIP files.

2. Order your repaired JPEG files
When I’m finished I’ll notify you about the number of files I am able to repair by email. Once you payed, I sent you the repaired files. If you first want proof I can sent watermarked samples. If you have a larger number of files to repair (10+), sent me an email (email@example.com) and we can discuss the price.

An example of stuff I can fix:

Types of JPEG file corruption
JPEG is a standard, a specification. A standard that describes how data inside JPEGs is stored. A JPEG is typically a chain of ‘markers’. One marker points to the next, then the next, etc.. Each marker serves a different purpose. For example, a marker can contain a comment. Another contains EXIF data which can contain all kinds of information on the image file: data taken, geo info, camera model etc.
The most important marker I guess, contains the actual image data. Roughly 5% of a JPEG file is meta data, the rest, 95% is the actual image. The 5% meta data is found at the start of the file and is also called the header.
A typical symptom of a damaged header is that the file is not recognized as a JPEG file and that it can’t be opened at all. To fix this kind of damage I also need an intact JPEG file, shot with the same camera using the same settings. If only some data inside the header is corrupt, depending on the image viewer you may get a more relevant error message, like “invalid huffman table” (which is required to decompress image data).
Corrupt image data
When the image data itself is corrupt, the JPG will probably load, however the image will be distorted. If a portion of the image data is missing (truncated file), part of the image will show. The latter is quite common after using photo recovery or file recovery software.
Another type of damage is bit corruption: Data inside the image ‘stream’ is corrupt. This can result in the image shifting and color errors.
How do I do it?
I am using a number of tools that are constantly under development. I call my tools the JPEG Repair Toolkit. It consists of 3 utilities. Apart from that I use a 3rd party hex editor and several photo editors for post processing.
JPEG Repair Toolkit consists of:
- A utility that checks JPEG structures. It follows and checks the chain markers I described earlier.
- A tool that allows me to modify the image stream at the byte level, just like a hex editor. It has a built-in JPEG image decoder that allows me to directly view the effects of the modifications that I make. Thus I do not have to switch from a hex editor to an image viewer all the time. I can also step through the decoding process so I can see at what byte address corruption is introduced. This is a very labor intense process that requires the human eye.
- As I change the image stream by adding, subtracting and modifying bytes I introduce new anomalies. To camouflage those I created an inpaint tool.
An example of what my “inpainter” can do: In this case it removed the runner. When doing JPEG Repair I remove the grey boxes with it.
