📄 Compress PDF
Make large PDFs smaller — perfect for scanned documents, reports and files that are too big to email or upload. Choose a compression level to balance file size against quality.
🖼️ Compress Images
Shrink JPG, PNG, WebP, GIF and BMP images. Adjust quality and maximum dimensions to get a much smaller file that still looks great.
