What image formats can I upload for compression?
This image compressor supports JPEG, JPG, PNG, GIF, BMP, and TIFF input files. The compression pipeline is designed for common web and social media image formats, converting all outputs to optimized WebP.
What format will I get after compression?

Uploaded files are processed only to generate compressed output and are not kept as a persistent image library. Files are handled in memory and deleted after processing. Privacy-first approach ensures your images are never stored.
