Compress PDF: what to know
This is lossy PDF compression: pages are rendered as JPEG images and placed into a new PDF. It can help with large scanned documents, but removes selectable text, links, forms, accessibility tags, and signatures. Keep your original. An already optimized PDF may become larger.

- Adjust visual quality
- Compare input and output size
- No upload of your PDF
Frequently asked questions
Will text remain searchable?
No. This compression method rasterizes each page. Use your original PDF when searchable text, forms, or accessibility tags matter.
Will every PDF become smaller?
No. Text-based or already compressed documents can become larger. The tool reports the actual size instead of promising a reduction.
