How much can PDFs be compressed?

Compression results vary depending on the PDF content. PDFs with embedded images typically see 10-50% reduction. Text-heavy PDFs may see less improvement since text is already compact.

Will the quality be affected?

Our compression optimizes the PDF structure (removing unused objects, using object streams) without re-encoding images. Text and vector graphics remain identical.

Can I compress multiple PDFs at once?

Yes! Add multiple PDF files and they will all be compressed. Download them individually or as a ZIP file.

Why didn't my file get smaller?

Some PDFs are already optimized and may not compress further. PDFs with mostly text or already-compressed images may see minimal or no size reduction.
