3. What is JPEG?

4. What is HEIC?

A HEIC file contains one or more images saved in the High Efficiency Image Format (HEIF), a file format commonly used to store photos on iOS devices.

5. What are raw images?

RAW images are uncompressed digital photos that save image data exactly the way the image was captured by camera’s sensor.

Because raw images are not compressed, they take up significantly more disk space than their JPEG counterparts (usually at least twice as much). However, because the original image detail in raw images is not compromised by image compression, they are higher quality than JPEG images.

6. Does the software repairs image file in the same format?

No, the software repairs the image file in JPG format.

7. Why am I getting an “Invalid Image” message, when I am selecting a JPEG file for repair?

An image file is made up of two parts namely the file container and image data. The container is the common structure which uniquely defines JPEG image. If the container of a JPEG file is damaged or is corrupt, then Stellar Repair for Photo software will not be able to identify the file as a JPEG file, and you will get an “Invalid image” message. Such images are corrupt beyond repair. That means such JPEG images are severely corrupt and it is not possible to repair them

8. What does NAME_T1.jpg, NAME_T2.jpg mean?

When you scan images for repairing, Stellar Repair for Photo software will scan and then list them. You will also be able to preview the image. Now, images which have thumbnails will get listed along with all its thumbnails. The thumbnail images will be named as IMAGE_NAME_T1.jpg and so on. T1, T2 is the name of the thumbnail of the same image. If an image has four thumbnails, it will get listed as IMAGE_NAME.jpg, IMAGE_NAME_T1.jpg, IMAGE_NAME_T2.jpg, IMAGE_NAME_T3.jpg, and IMAGE_NAME_T4.jpg.

9. Why are some JPEG files not completely repaired?

An image file is made up of two parts namely the file container and image data. The container is the common structure which uniquely defines JPEG image. If the container of a JPEG file is damaged or is corrupt, then Stellar Repair for Photo software will not be able to identify the file as a JPEG file, and you will get an “Invalid image” message. In case, the container of a JPEG file is intact, but its image data is corrupt even then Stellar Repair for Photo will be able to repair the image. Such a repaired image will have defects like loss of color, or a part of the image will be missing. These defects are due to image data being corrupt.

In such situations, there is an advise that you try and extract the thumbnail of the image (if any).
