utilizeHow this PDF compressor works
Upload a PDF and choose one of two modes. Balanced rebuilds the document's internal structure to remove redundant data while keeping the original text, fonts, and images intact — a safe option that preserves searchability. Maximum compression renders each page to an image at your chosen resolution and quality, then assembles a new PDF from those images. This can dramatically shrink scanned documents or PDFs full of high-resolution photos, at the cost of text no longer being selectable.
Choosing a resolution and quality
- 150 DPI looks sharp when printed and is a good default for most documents.
- 96–120 DPI is usually fine for documents that will only be viewed on screen.
- 72 DPI gives the smallest files, suitable for quick previews rather than printing.
- Lowering the JPEG quality slider reduces file size further but can introduce visible artifacts around text and fine lines.
Which mode should I use?
If your PDF was created from a Word document, spreadsheet, or other digital source, start with Balanced — it often preserves full quality with little size change, and keeps your document searchable. If your PDF is a scan, a photo-heavy report, or Balanced didn't shrink it enough, try Maximum compression.
Will I lose any content?
Balanced mode does not remove or alter content. Maximum compression preserves the visual appearance of every page but converts the page to an image, so any text becomes part of that image and can no longer be selected, searched, or copied.
Do you store or see my document?
No. Everything — reading, rendering, and rebuilding the PDF — happens locally in your browser. Your file is never uploaded anywhere.
