Resize before compressing
The fastest image is the one that is not larger than it needs to be. Uploading a 4000 pixel photo into a 900 pixel content area wastes bandwidth and slows down the page.
Start with Image Resize. Set the actual width needed by your layout, then compress the resized version. This usually gives a much better result than compressing a huge original file.
Use the right compressor for the format
Use JPG Compressor for photos, PNG Compressor for transparent graphics and WebP Compressor for modern web delivery. Each format handles quality and transparency differently.
Always compare the visual result with the original. The best setting is the lowest file size that still looks professional on the page.
Optimize images by role
Hero images need more detail because they are large and highly visible. Thumbnails, avatars and inline illustrations can usually be compressed harder. Product images should stay sharp enough for inspection.
For blog images, a balanced WebP export is often ideal. For screenshots, keep text readable and avoid compression that blurs interface labels.
Build a simple publishing checklist
Before publishing, check image dimensions, file size, visible quality, alt text and format. Then test the page on a phone connection if possible. Image optimization is one of the most reliable ways to improve perceived speed.
Use Image Compress for a quick general workflow when you are not sure which specific compressor to choose.
Frequently asked questions
Should I resize every image?
Resize images that are much larger than their display size. Keep originals separately for future editing.
Does compression reduce quality?
Lossy compression can reduce detail, so compare the preview and choose a balanced setting.
What format should blog images use?
WebP is a strong default for modern websites, with JPG as a compatibility fallback when needed.
