Reduce file size without losing quality.
Got a large PDF book that's too big to share, upload, or store? Our tool compresses eBooks, novels, textbooks, and manuscripts – keeping text crisp and formatting intact. Perfect for authors, publishers, students, and avid readers. No sign‑up, no software – just upload and download.
Did you know? A typical 300‑page novel in PDF format is around 2‑5MB. With images, it can exceed 20MB. Compressing it can reduce the size by up to 80% – making it easy to email, upload to e‑readers, or share with friends.
Large book files create challenges. Here's why you need to compress your PDF book:
Digital libraries and e‑readers fill up quickly. Compressing books saves significant storage space on your devices and cloud accounts.
Email and messaging apps often have file size limits. A compressed book PDF sends instantly and doesn't get rejected.
Downloading a 20MB book on a mobile network can take time and consume data. A 3‑5MB file is much faster.
Many platforms (LMS, publishing portals, etc.) impose file size caps. Compressing ensures your book uploads without issues.
Here's a typical breakdown of book PDF sizes and the results you can expect with compression:
Results vary based on image quality and content. Our tool finds the optimal balance for your specific book.
Books have unique characteristics – we optimise specifically for them:
The result is a PDF book that's significantly smaller, yet retains full readability and structural integrity.

🚀 Need extreme compression for illustrated books? Try Hyper Compress
If your book has many high‑resolution images, Hyper Compress applies aggressive JPEG compression and grayscale conversion to shrink it even further – sometimes down to 10% of the original size.
Yes. Our tool is optimised for text‑heavy content. Text remains sharp and vector‑based – we only compress images and remove metadata, while all text stays clear and searchable. For books with many illustrations, you may notice some image quality reduction, but text is always preserved.
No. Page layout, fonts, margins, and structure are fully preserved. The compression only reduces the file size – it does not alter the content or design of your book.
For text‑heavy books, you can reduce file size by up to 70‑80%. For illustrated books or scanned manuscripts, reduction is typically 50‑70%. A 10MB novel can often be compressed to 2‑3MB without noticeable quality loss.
Absolutely. We use TLS encryption and auto‑delete all files within 2 hours. Your intellectual property is safe and confidential.
Yes. Scanned books are image‑based and often very large. Our compression works well on scanned PDFs – for even better results, consider using our OCR tool first to convert to searchable text, then compress.
Yes. Internal links, bookmarks, and table of contents are fully preserved. Only metadata like EXIF from images is removed, but structural elements remain intact.

Upload your book PDF and get a smaller version that's perfect for e‑readers, email, and archiving – fast, secure, and easy.
PDF books often contain hundreds of pages with text and occasional images. Our tool applies efficient stream compression and font subsetting to reduce file size significantly while preserving readability. For image‑heavy books, use "Maximum" compression.
