Do you have a JPG image file that will not open or display correctly? If so, our free-to-use JPG repair tool may be able to help. Our tool analyses the content of your JPG image file and is able to determine if the file pixel data is valid. Our tool will let you know what is wrong with your JPG file and attempt to fix it.
Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.
Here are 3 simple steps to repair your JPG using our fast and free repair tool.
No. Our JPG repair tool will not adjust the resolution or quality of the repaired image file.
Yes! Our JPG repair tool is 100% free to use.
No, you can repair as many files as you wish. We do not have any limits when using our JPG repair tool.
We aim to process JPG repairs as quickly as possible; this usually takes around 5 seconds; however, this may be longer depending on the file size and data needed to be repaired.
Once your JPG has been selected, it will undergo some initial checks to verify that the file has some basic information. If the initial checks pass, we then upload the file to our servers for more detailed analysis.
Yes, of course it is! Your JPG, once repaired, is deleted 15 minutes after upload, and any download link will expire after this time.
Yes! Our JPG repair tool will run on any system with a modern web browser.

A JPG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.
The compression used by JPG encoders is "lossy", meaning image colours that are not perceptible to the human eye are discarded during the compression process. The removal of this colour data greatly reduces the size of the final JPG file with no discernible loss in quality.
Due to their compact and high-quality format, JPG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPG files can be edited within most popular image editing software.
The data contained within a JPG image file is binary, and it is the first sequence of bytes within the file that contains the header data for the image, which contains information such as image width, height, colour depth, palette, and other metadata.
Knowing how this header data is formed and what the header data should be for each individual file type allows our tool to not only ensure the file is using the correct file extension but also that all the expected pixel data is present and correct.
Certain image file formats, such as JPG, store their data in a compressed state whereby pixel detail is not identical to the original image. The loss of detail is usually not noticeable and can save a lot of space, leading to much reduced file sizes. An example of a non-lossy format would be the BMP format, which stores pixel data at exactly the same level of detail as the original image. When it comes to validating and repairing an image file, the fact that the format is lossy or non-lossy does not really affect the repaired file. Any repaired file will be in the same format, and our tool will respect the original compression settings.
