Step-by-step guide
- Step 1: Select a JPG, PNG, or WebP image.
- Step 2: Select your quality setting (Small file, Balanced, High quality) and optional max width limit.
- Step 3: Click "Compress Image" to process and download your optimized image.
Shrink heavy image files for websites, emails, and forms. Adjust compression quality and set optional maximum width bounds, converting images into lightweight WebP format.
WebP provides superior compression ratios compared to legacy JPG and PNG formats, maximizing file size reduction.
No. When you set a maximum width, the height is automatically scaled proportionally to maintain the exact original proportions.
No. All image compression and canvas encoding happen directly in your browser memory.
PDF Toolbox is engineered with a strict browser-first architecture. All file operations execute entirely in your local browser sandbox via modern WebAssembly and JavaScript engines. No file bytes or sensitive document data are ever uploaded, buffered, or stored on external servers or cloud infrastructure. Memory buffers are cleared immediately when you finish or close your tab.
