About Image Compressor
Image compression reduces file size so images load faster, upload faster, and consume less bandwidth. This is useful before adding screenshots to blog posts, product pages, email campaigns, or documentation.
A good compression workflow keeps visual quality high while reducing unnecessary bytes. Compare the original and compressed result before replacing important source files.
Common use cases
- Compress website images before publishing.
- Shrink screenshots before sending them in email or chat.
- Reduce file size for upload limits.
- Prepare images for faster mobile loading.
Practical tips
- Use JPEG or WebP for photos and PNG for graphics that need crisp edges or transparency.
- Keep a copy of the original file for archival use.
- Check the compressed result at the size where it will actually be displayed.
