How to Reduce PDF File Size Without Losing Quality

Large PDF files can be a pain to share via email, upload to portals, or store on cloud drives. Many people turn to online compressors, but those often upload your files to third-party servers. With browser-based compression, you can stay private and still shrink file sizes effectively.

Why File Size Matters

Emails usually have attachment limits of 20–25MB. Uploading large files can also be slow, especially on mobile data connections. Reducing size ensures smoother transfers without compromising quality.

Tips to Reduce PDF Size

• Remove unnecessary images: If you only need text, strip large images.
• Use compression settings: Adjust DPI and image quality carefully.
• Split files: If compression alone isn’t enough, use our PDF splitter to divide documents into smaller parts.

Our upcoming compression feature will run locally, giving you the benefits of speed and privacy without online uploads.

In the meantime, you can combine smaller optimized PDFs using our PDF merger.
