Make Your PDF Smaller

Email attachments, upload forms and job portals often reject PDFs that are too large. Most of that weight usually comes from photos and scans embedded in the document. QodeCat Compress PDF shrinks those images so the file fits, and shows you exactly how much space you saved before you download.

• Recommended mode: Downscales and recompresses the JPEG images inside the PDF. Text, fonts and vector graphics are left untouched and stay selectable.
• Maximum mode: Renders every page as a JPEG image and builds a new PDF with the same page sizes. Best for scanned documents; text is no longer selectable or searchable.
• Three quality presets: Low, Medium and High, so you can trade file size against image sharpness.
• Honest results: If the compressed file would not be smaller, you keep your original and the tool tells you it is already optimized.

Why use this tool?

Your File Stays on Your Device

Many online PDF compressors upload your document to a server. This one does not. Images are decoded and re-encoded by your own browser, so contracts, medical records and other sensitive files are never sent anywhere.

Which Mode Should I Pick?

Start with Recommended. It only touches images, so the document looks and behaves the same. If your PDF is a scan, or Recommended did not save enough, try Maximum: it usually gives the biggest reduction, but the pages become pictures.
