Compress PDF

Reduce PDF file size while preserving content and structure.

Upload a PDF and get a smaller version back. Removes redundant objects and uses optimized object streams.

PDF files grow over time as they accumulate redundant objects, embedded fonts, multiple revision streams, and unoptimized structure. Our compressor removes this overhead and uses more efficient object streams to reduce file size without touching the visible content.

Compression results vary significantly by file content. PDFs with lots of duplicate objects, form fields, or revision history often shrink 20–50%. Image-heavy PDFs where the images are already optimized may see minimal reduction.

The visual content of your PDF is not changed — no images are resampled, no fonts are removed, and the document looks identical in any PDF viewer after compression.

How to use Compress PDF

Step 1: Upload your PDF by dragging it in or clicking to browse.
Step 2: Click "Convert now" — compression settings are applied automatically. No configuration is required.
Step 3: Download your smaller PDF. The content and appearance are identical to the original.

Frequently Asked Questions

How much smaller will the PDF get?

Results vary. PDFs with duplicate objects or unoptimized streams often shrink 10–40%. Image-heavy PDFs may not shrink much.

Will the content look different?

No. Compression only affects how data is stored inside the file, not the visible content.
