TIF images (also called TIFF) are high-quality image files often used by photographers, or in situations where large, but lossless image files are preferable. On the other hand, JPG (or JPEG) image files are much smaller and use a lossy algorithm. This makes them useful for use on websites or sharing files in general.

Yes, converting from TIF (or TIFF) to JPG is very likely to result in some loss of quality. This is because JPG uses a lossy compression format, which will result in a much smaller file size, but a relatively lower quality image. It's worth remembering that while JPEG compression introduces artefacts in the image, it remains both usable and useful.

In pretty much all cases, it should be accepted that a conversion from TIF to JPG will result in some quality loss. However, many converters present custom options, which can help a bit. Use these customizations to choose a high-quality JPG image and reduce the compression.

In converting TIF to JPG, remember to check for any metadata preservation needs. Additionally, it's helpful to consider JPG quality settings including compression, to ensure better and predictable results.
