Image compression for Dokuwiki users

While DokuWiki doesn't automatically compress images upon upload, users are encouraged to compress them beforehand for better performance and storage efficiency. DokuWiki itself offers some resizing capabilities with the w parameter, but it requires the tok parameter for proper functionality. Users can utilize various online tools or software to compress images before uploading them to their DokuWiki site.

Here's a more detailed explanation:

• DokuWiki's Image Handling:

  DokuWiki allows embedding images using the {{image.jpg}} syntax. It also provides resizing options using the w parameter (width) in the URL, but this often requires the tok parameter for it to work correctly according to DokuWiki documentation.

• Why Compress?

  Compressing images before uploading them to DokuWiki is beneficial for several reasons:

  • Reduced File Size: Smaller image files mean faster loading times for web pages, improving user experience.
  • Optimized Storage: Less storage space is required for compressed images, especially when dealing with a large number of images.
  • Faster Uploads: Uploading smaller files is quicker, saving time and bandwidth.

• Compression Methods:

  • Lossless Compression: This method reduces file size without sacrificing image quality, suitable for preserving details (e.g., for photos) according to Adobe.
  • Lossy Compression: This method reduces file size by discarding some image data, which can result in a slight decrease in quality but significantly smaller files.

• Tools for Compression:

  There are numerous online and offline tools available for image compression:

  • Online Tools: Websites like Shrink.media, Fotor, and Shrink-images.org) offer free image compression services.
  • Software: Programs like Photoshop, GIMP, and others offer advanced image editing and compression features.
