Image Optimization Guide

When publishing images on a website, it is often better to optimize them for the screen size and use case instead of uploading the original file unchanged. Oversized images can slow the first page load and increase mobile data usage.

For many photos, lowering quality to the 75% to 85% range keeps the image visually close to the original while reducing file size. Product images and portfolio work may need a higher quality setting, while thumbnails and blog body images can usually be compressed more aggressively.

WebP is a modern image format that can create smaller files than JPEG or PNG. It is supported by most modern browsers, so it is worth considering for web publishing. Some images may become larger after conversion, so comparing the result size before downloading is a good habit.

This tool processes images inside the browser without uploading them to a server. It is useful when you want to quickly reduce private photos or work-in-progress images without installing a separate editor.

• Body images are often sufficient between 1200px and 1920px wide.
• Around 80% quality is a practical balance between file size and visual quality.
• For PNG files with important transparency, review the result before choosing WebP.
• Keep a separate copy of important original files before compression.
