Yes, you can upload PDF files up to 10MB in size. For larger files, you may need to use desktop software.
Compression results vary depending on the content of your PDF. Files with many images typically see greater size reduction (up to 70-80%) compared to text-heavy documents (typically 20-30%).
Yes, we take data security seriously. This tool processes your files entirely in your browser - your PDFs are never uploaded to our servers. This means your sensitive documents never leave your device, ensuring complete privacy and security.
Our compressor is designed to maintain a balance between file size and quality. While some minor reduction in image quality may occur, text and document structure remain intact. You can adjust compression settings to prioritize quality or file size reduction.
Compressing PDFs is useful for many purposes: reducing file sizes for email attachments, saving storage space, improving website loading times for downloadable PDFs, meeting file size upload limits, or optimizing documents for mobile viewing.
No, we don't store any of your files. Since the compression happens entirely in your browser, your files never reach our servers. Once you close the browser tab or navigate away, all processed data is automatically cleared from your browser's memory.
