How to Use Image Compressor Pro
Our tool runs entirely within your browser, ensuring your images are processed instantly and securely without ever being uploaded to an external server.
Step-by-step guide
- Upload: Drag and drop your images into the designated drop zone at the top of the app, or click it to browse files. Batch uploads are supported.
- Live preview: Adjust the quality slider, set a target size, or apply crops using the sidebar. Watch the file size and visual quality update in real time in your gallery.
- Target file size (advanced): Need an image under a specific KB limit for a portal? Enable "Target specific file size" and input your limit. The tool auto-tunes settings (and downscales resolution if necessary) to fit your limit.
- Strict size capping: If you leave the output on "Keep Original Format", the algorithm guarantees the output file will never be larger than the original.
- Download: Click download on individual image cards, or use the bulk "Download All (ZIP)" button. Files are automatically renamed using a smart convention to prevent overwriting.
