Common Questions Before Contacting Us

Before sending a message, you may find your answer in our FAQ section on the homepage. Common topics include why compressed PDFs appear image-like, how to compress to exactly 100KB, and how to use the quality slider for precise control.

If you are having trouble compressing a specific PDF, please include details about the original file size, the number of pages, and the error message (if any) in your message. This helps us diagnose the issue quickly.

For feature requests, we welcome all suggestions. Our most popular user-requested features — including the quality slider, target size mode, and real-time preview — were all added because of feedback from users like you.
