There are a ton. Most things that use wavelets to encode the data fall into this category. Often the same file format and "extension" can have multiple actual encoding mechanisms on the inside, so it might sometimes have lossy compression and sometimes not. Examples of file formats with lossy compression include mp3,jpeg and mpeg. Container formats like avi, and wma sometimes do and sometimes don't.

What is the difference between JPG and TIFF file formats?
The main difference between JPG and TIFF file formats is the way they store image data. JPG files use lossy compression, which reduces file size but can result in some loss of image quality. TIFF files, on the other hand, use lossless compression, which preserves image quality but results in larger file sizes.
Difference between lossless and lossy compression?
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.
Is a PICT a type of Lossy or Lossless compression file?
Pict files can use 2 different forms of compression. 1- RLE Compression (the default) is lossless. 2- JPEG compression (only on some systems/graphics programmes) is lossy.
What is a JPG photo and how is it different from other image file formats?
A JPG photo is a type of image file format that uses compression to reduce file size while maintaining image quality. It is commonly used for photographs and graphics on the internet. JPG files are different from other image formats like PNG or GIF because they use lossy compression, which can result in some loss of image quality.
How pack files smaller?
To pack files smaller, you can use file compression techniques such as ZIP, RAR, or 7z formats, which reduce file size by removing redundancies. Additionally, consider using lossless compression for text and images, or lossy compression for audio and video files to achieve greater size reductions. You can also remove unnecessary metadata or optimize file formats for better efficiency. Finally, using tools like WinRAR, 7-Zip, or built-in compression features in operating systems can help automate this process.
Is JPEG a good file format for printing images?
JPEG is not the best file format for printing images because it uses lossy compression, which can result in a loss of image quality. For printing, it is recommended to use file formats like TIFF or PNG, which offer higher quality and better resolution.
What are the differences between jpg and tiff file formats in terms of image quality and compression?
JPEG (JPG) and TIFF are two common image file formats that differ in terms of image quality and compression. JPEG files use lossy compression, which reduces file size by discarding some image data. This can result in a loss of image quality, especially when the file is compressed multiple times. TIFF files, on the other hand, use lossless compression, which retains all image data and does not degrade image quality. This makes TIFF files larger in size compared to JPEG files, but they are preferred for high-quality images that require preservation of detail and color accuracy.
What is the difference between using JPG and PNG formats for printing purposes?
The main difference between using JPG and PNG formats for printing purposes is the way they handle image compression. JPG files use lossy compression, which can result in a loss of image quality, especially when the file is repeatedly edited and saved. PNG files, on the other hand, use lossless compression, which preserves image quality but can result in larger file sizes. For printing purposes, PNG is generally preferred for its higher quality, while JPG is more commonly used for web images due to its smaller file sizes.
Why would you select for example a JPEG or tiff filre format?
TIFF would be used for high quality photos and print files, while JPEG would be used where file size is an issue, and quality isn't as important. JPEG and TIFF are a couple of the most common examples of lossy and lossless compression, respectively.File formats that use lossy compression throw away pieces of information as they compress the file for a compact file size. This usually isn't too much of an issue except when compression is set high, or a file is saved multiple times in a lossy format.File formats that use lossless compression manage to keep every bit of information about your picture, but use clever algorithms to compress where possible (for instance, a large area of white could be noted as such, rather than a vast array of white pixels). Even compressed lossless files are much larger than lossy ones.It boils down to quantity versus quality.
What is the difference between a PNG and a TIFF file format in terms of image quality and compression?
PNG and TIFF are both image file formats, but they differ in terms of image quality and compression. PNG files are typically smaller in size and use lossless compression, meaning they retain high image quality without losing any data. On the other hand, TIFF files can support both lossless and lossy compression, allowing for higher quality images but also larger file sizes. Ultimately, PNG is better for web use and images with transparency, while TIFF is preferred for high-quality printing and professional photography.
How do you convert from pixel to kilobyte?
There is no straightforward conversion. An image that has (for example) 800 x 600 pixels needs to represent that many picture points. Without data compression, each picture element needs about three bytes (depending on the color depth); however, formats such as JPEG do use data compression, more precisely, lossy data compression - and the factor by which data is reduced with data compressed varies, depending on the image quality. That is, in lossy data compression, more compression means less quality.
Is a PNG file format better than JPEG for image quality and compression?
PNG file format is better than JPEG for image quality because it supports lossless compression, which preserves image details without sacrificing quality. However, PNG files are larger in size compared to JPEG files, which use lossy compression.
