The TN3 (Tiny High Resolution Image) file extension is a type of image file format developed to store very small but high-quality images. The uniqueness of this file format lies in its ability to compress the image data without any visible degradation in terms of detail and quality when compared to the original image. By using a combination of compression techniques such as run-length coding and Golomb code, the TN3 file extension can be used to store and transmit photos which are relatively small in size while preserving their original quality.
Compatibility & File Size
TN3 files are compatible with many digital cameras that allow you to save in this particular format. When compared to other popular file formats such as JPEG, TIFF and RAW, TN3 can provide up to both 10 times smaller file sizes from photos of the same quality. When compared to the more efficient JPEG 2000 format, TN3 can offer up to 20% smaller file sizes depending on the degree of color information contained within the image. Generally speaking, a TN3 file size is roughly half that of an equivalent-quality JPEG.
Advantages & Limitations
The strength of TN3 lies in its ability to provide relatively small file sizes while preserving image clarity and quality. This can be beneficial when needing to upload photos over an online connection or storing multiple large images on a computer or device with limited storage capacity. However, the TN3 format only supports 24-bit RGB color values and doesn’t support higher color depths such as CMYK. Other similar image formats include .PNS, .JNG, .PPM, and .MTV
.After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .TN3) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .TN3 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .TN3 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .TN3 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .TN3 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .TN3 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .TN3 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .TN3 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .TN3 file) will be extended to the maximum.
It is also good to check
- if the .TN3 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
