Big PDF in, tiny PDF out.
Shrink large, scanned or image-heavy PDFs with an adjustable quality and resolution, so they fit email limits and upload forms. Everything happens in your browser — your document never leaves your device.
Add a PDF
Drop in your PDF — it's read locally, never uploaded.
Set the quality
Choose a resolution and quality; lower means a smaller file.
Compress & download
See the size savings and download your smaller PDF.
Is my PDF uploaded?
No. The PDF is compressed entirely in your browser — it never leaves your device, so confidential documents stay private.
How does the compression work?
Each page is re-rendered as an image at your chosen resolution and quality, then rebuilt into a new PDF. This dramatically shrinks scanned and image-heavy PDFs.
Will the text stay selectable?
Because pages are rasterized to images, text becomes part of the image and is no longer selectable. This tool is best for scanned or photo-heavy PDFs where size matters most.
How small can it get?
It depends on the source, but scanned documents often shrink by 70–90%. Lower the quality or resolution for even smaller files.
Is it free?
Yes — completely free, no sign-up and no watermark.
