Image Compression Guide: Faster Pages Without Ruining Quality
Learn how to reduce image size while keeping visuals clear and useful.
Why compression matters
Images often make up the largest part of a webpage. Compressing images can improve speed, mobile experience, and overall usability.
Resize before compressing
If a website displays an image at 900 pixels wide, uploading a 4000 pixel version wastes bandwidth. Resize first, then compress.
Lossy vs lossless
Lossy compression removes some detail for smaller files. Lossless compression keeps more data but usually saves less space.
Best practices
- Use the right image dimensions.
- Compress before publishing.
- Use descriptive file names.
- Add alt text.
- Check quality after compression.
