Lossless vs lossy compression: What is the difference?
Understand how compression affects images, audio, video and documents.
The core difference
Lossless compression keeps the original information recoverable. Lossy compression removes some information to create smaller files.
Examples of lossless formats
PNG and FLAC are common examples where quality preservation matters. These files can still be large depending on content.
Examples of lossy formats
JPG, MP3 and many video exports use lossy compression to reduce file size significantly.
When lossy is acceptable
Lossy compression is often fine for photos, streaming, social media and casual listening when settings are chosen carefully.
When lossless matters
Use lossless formats for editing, archiving, logos, text-heavy screenshots and files that may be converted again later.
Frequently asked questions
Is lossy compression bad?
No. It is often the right choice when small file size matters more than perfect preservation.
Can lossy compression be reversed?
No. Removed information cannot be fully restored.
Is PNG lossless?
Yes, PNG is generally used as a lossless image format.
