Best image compression tools
The best tool is the one that shows a clear preview and lets you balance file size against visual quality instead of blindly shrinking everything.
This guide explains a simple image optimization workflow for campaign assets, site graphics, previews, and documents.
Do not upload a 4000-pixel image when the page or document only needs a smaller visual. Resize first, then compress.
Use the Image Toolkit to preview the result. Stop when the file is lighter but still readable and clean.
Use WebP or JPEG for photos, PNG for transparent UI assets, and avoid repeated recompression of the same source file.
After optimizing images, publish them with descriptive alt text, width, height, lazy loading, and async decoding where the page allows it.
