Frequently Asked Questions

How does the PDF compressor work?

Our PDF compressor reduces the file size of your PDFs by optimizing images, removing redundant information, and applying compression algorithms. Simply upload your PDF and download the compressed version.

Is there a file size limit for compression?

Yes, you can upload PDF files up to 10MB in size. For larger files, you may need to use desktop software.

How much can I expect my PDF to be compressed?

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%).

Is my data secure when using this compressor?

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.

Will compression affect the quality of my PDF?

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.

Why would I need to compress PDFs?

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.

Do you store my PDF files after compression?

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.
