Question 1

What is the difference between lossy and lossless compression?

Accepted Answer

Lossy compression reduces file size by removing some image data (e.g., JPEG), while lossless compression retains all original data (e.g., PNG). Lossy compression results in smaller files but can reduce quality.

Question 2

How much can I compress an image without losing quality?

Accepted Answer

This depends on the image content and format. Photos can often be compressed by 70-80% with minimal visible quality loss. Graphics with text or sharp edges require more careful compression to maintain clarity.

Question 3

Which formats should I use for different image types?

Accepted Answer

Use JPEG for photographs, PNG for graphics with transparency or sharp edges, WebP for modern web applications (better compression), and SVG for simple graphics and icons that need to scale.

Question 4

Will image compression affect my website's SEO?

Accepted Answer

Proper image compression improves SEO by reducing page load times. Search engines prefer fast-loading sites. Just ensure images remain clear and relevant to your content.

Question 5

How do I check image quality after compression?

Accepted Answer

Compare the original and compressed image at 100–200% zoom. Look for artifacts, blurry areas, and text. Good compression makes the file smaller without noticeable degradation in quality.

Question 6

What is the WebP format and why should I use it?

Accepted Answer

WebP is a modern image format developed by Google that offers superior compression (both lossy and lossless) compared to JPEG and PNG. It results in smaller files with comparable image quality, improving website performance.

Question 7

How does image resolution affect file size after compression?

Accepted Answer

Images with higher resolution (more pixels) typically result in larger files. Before compression, it is recommended to resize the image to the maximum dimensions it will be displayed on the website to avoid processing unnecessary data.

Question 8

Can I compress multiple images at once?

Accepted Answer

Image compression tools offer batch processing, allowing you to upload and compress multiple images simultaneously to save time.
