What is Image Compression?
Image compression is the process of reducing the file size of an image by removing redundant or unnecessary data. The goal is to make the image as small as possible in terms of bytes, so it takes up less storage space and can be transmitted and loaded faster over the internet, without significantly degrading its visual quality.
Lossy vs. Lossless Compression
- Lossy (e.g., JPEG)
- This method achieves a much smaller file size by intelligently discarding some data from the image. This results in a minor (and often unnoticeable) loss of quality. The level of compression is adjustable (like with the quality slider above). This method is ideal for photographs and complex images with many colors.
- Lossless (e.g., PNG)
- This method reduces file size without discarding any data from the original image. It finds more efficient ways to represent the existing data, similar to how a ZIP file works. The quality is perfectly preserved, but the file size reduction is generally less dramatic than with lossy compression. This is best for logos, icons, and images with text or sharp lines where quality is paramount.
Why You Should Compress Images for the Web
- Faster Page Load Times: Smaller images download faster. A fast website leads to a better user experience, lower bounce rates, and higher engagement.
- Improved SEO: Website speed is a confirmed ranking factor for Google. Optimizing your images is a crucial step in technical SEO.
- Bandwidth Savings: Serving smaller image files reduces data transfer from your server, which can lower hosting costs and save mobile data for your users.
