File compression

Compression reduces storage or transfer size. An archive such as ZIP can bundle files; a media codec may compress the content itself. Check compatibility and extraction needs.

Formats

ZIPZIP packages files and folders into an archive. Compression methods and optional encryption depend on how the archive was created and what the receiving tool supports.7Z7Z is an archive format used by 7-Zip and compatible tools. Compression and optional encryption settings can vary, so recipients need an extractor that supports the chosen options.JPEGJPEG is a lossy image format used widely for distributing photographs.MP3MP3 reduces audio size through lossy encoding. CBR keeps a constant bitrate, while VBR varies allocation with audio complexity; neither restores the discarded source information.

Compare

7Z vs ZIP7Z and ZIP both bundle multiple files. 7Z suits workflows that need flexible compression settings, while ZIP is often easier to extract across operating systems without extra software.

Guides

Choosing an Archive FormatZIP is a practical first choice for unknown recipients. Consider 7Z when their extraction tools and settings can be confirmed.

Lossless and lossy compressionLossless compression can restore the original data; lossy compression discards information to reduce size. Keep an appropriate source file when future editing matters.File formatsA file format defines how data is represented and interpreted. Choose one by the recipient's software, editing needs, fidelity and long-term access, not by extension alone.
