Frequently Asked Questions
Will compressing a PDF reduce the text quality?
No, our algorithm prioritizes text clarity. Even at high compression levels, text remains sharp and readable. Only images are re-sampled to achieve size reduction.
How is this tool more secure than others?
We use WebAssembly technology to process files directly in your browser. Since your files are never uploaded to a server, there is zero risk of data interception or storage by third parties.
Can I batch compress multiple files at once?
Yes, you can upload and process up to 10 PDF files simultaneously. This allows for efficient workflow management when dealing with large document sets.
