About This Tool

This PDF compression tool reduces file size by re-encoding embedded images, downsampling non-essential assets, and simplifying non-critical objects within the document. It preserves the document structure, text, and form fields while removing non-essential metadata to minimize size.

Input is a single PDF file with an optional compression profile (Balanced, High, Maximum) and an optional target size. The system outputs a new PDF file, the new size in bytes, and a concise quality and size report.

Designed for professionals who share large PDFs with clients, colleagues, or external portals. Typical use cases include sending marketing reports, legal PDFs, research papers, and project proposals where delivery speed and storage are critical.

The value comes from predictable size reductions without manual tweaking, clear size reports, and presets that align with common requirements. The tool is optimized for privacy by processing inputs without exposing content beyond the run and reporting only essential metrics.

Frequently Asked Questions

Find Quick Answers

What inputs can I compress?

The tool accepts standard PDF files up to the platform's per-file size limit. Password-protected or encrypted PDFs may require removal of protection or cannot be compressed until the password is provided; encrypted content may not compress reliably.

How does compression affect quality?

Compression reduces file size by downsampling images and recompressing streams. A Balanced profile aims to preserve legibility and form field integrity, while High and Maximum profiles prioritize smaller sizes at the potential cost of image clarity in images and complex graphics.

Is there a limit on file size or number of files?

Per-file size limits apply and automated batch processing is not included in the standard tool. For multiple files, each PDF must be processed individually or via an API with batching in a higher tier, subject to policy.

Is my data private?

Uploads are processed temporarily and are not stored long-term. Content is used solely for the compression operation and is not exposed to other users. For sensitive material, consider offline processing.
