Optimization tools
Choose an image optimization tool for the question you need to answer: assess a file, inspect its size, prepare website images or produce a WebP result. These five tools process images in your browser and show measured file information. Start with an analyzer when you need to understand the original, or choose an optimizer when you want a downloadable result.
5 optimization tools
Image Optimization
Analyze an image and optimize format, dimensions and quality locally.
Image Optimization Checker
Check an image’s optimization score and category breakdown.
Image Size Analyzer
Inspect image file size and dimensions before an upload.
Web Image Optimizer
Choose format and dimensions for images displayed on websites.
WebP Optimization
Optimize images to WebP while preserving transparent areas.
Which tool should I use?
Unlike the single-step compressors, the five optimization tools below inspect an image across format efficiency, pixel dimensions, bytes-per-pixel (BPP) density, and decoded RGBA memory (`W × H × 4` bytes) before recommending or applying changes. Pick the tool that matches your diagnostic or publishing step.
Every check and encode runs locally in your browser tab. If you only need to inspect exact decimal KB (1,000 B) vs binary KiB (1,024 B) and portal cap compliance without modifying the file, start with the read-only Image Size Analyzer; if you are preparing an asset for a specific webpage layout slot (Hero, Blog, Product card or OpenGraph), use Web Image Optimizer to enforce dimension bounds and copy CLS-safe `<img>` HTML.
- Image Optimization Tool — you want an overall optimization score (0–100) and a one-click optimized WebP download in the same workbench.
- Image Optimization Checker — auditing whether an existing image is ready to publish and comparing real WebP, JPEG and PNG candidate byte sizes side by side.
- Image Size Analyzer — inspecting exact decimal KB vs binary KiB, bytes-per-pixel density, decoded RGBA memory and portal KB caps without modifying the file.
- Web Image Optimizer — fitting an image into a specific page layout slot (Hero, Blog, Product card or OpenGraph) with verified dimension and byte-budget compliance plus CLS-safe HTML markup.
- WebP Optimization — tuning WebP quality manually (50–95), locking original dimensions if needed, and verifying the RIFF/WEBP binary header.
