Frequently Asked Questions

Is it safe to compress PDFs online?: Yes, our PDF compressor is safe. Your file is processed securely and deleted immediately after compression — we never store your documents.
How much can I reduce the PDF file size?: Typical compression reduces file size by 30-70%, depending on the content. PDFs with large images see the biggest reductions. The tool shows you the exact before and after sizes so you know how much space you saved.
Will compression reduce PDF quality?: Our smart compression algorithm is designed to minimize visible quality loss. Text remains crisp and sharp, while images are optimized at a level that preserves visual clarity. The result is a significantly smaller file that looks virtually identical to the original.
Why is my PDF file so large?: Large PDF files are usually caused by high-resolution images, embedded fonts, or multiple layers from editing software. Scanned documents are especially large because each page is stored as a full image. Our compressor targets these elements to dramatically reduce file size.
Can I compress a PDF for email attachment?: Yes. Most email services limit attachments to 25 MB. Our compressor can typically reduce a PDF well below that threshold. The before and after sizes are shown so you can verify the file is small enough to send.
Does compressing a PDF remove any pages or content?: No. Compression only optimizes images and internal data structures — it never removes pages, text, or any visible content. Your document will look and read exactly the same, just in a smaller file.
