Compress a PDF - reduce file size

Compression results vary based on PDF content. PDFs with large images typically see 30-70% reduction. Documents with mostly text or already optimized images may see minimal change.

Our compression optimizes images and removes redundant data. Text remains crisp. Image quality may slightly decrease for maximum file size reduction, but remains visually acceptable for most uses.

Some PDFs are already optimized or contain mostly vector graphics and text. If compression cannot reduce size, we return your original file unchanged to avoid any quality loss.

Files are temporarily stored for processing in private storage and on the processing server. During normal operation, document copies are automatically deleted within five minutes after processing finishes. Download needed results promptly; there is no long-term document storage.

You can compress PDFs up to 50 MB on our website.

No. Compression only optimizes the internal structure and images. All content, links, and functionality remain intact.

Password-protected PDFs need to be unlocked first before they can be compressed.

No. Once compressed, you cannot restore the original image quality. Always keep a backup of important documents before compressing.
