About Compress PDF

Compress PDF makes large PDF files smaller so they can be emailed or uploaded to portals with size limits. It works best on scanned documents and files full of pictures.

Frequently asked questions

Can I compress a PDF under 1 MB?

Enter 1024 as the target size. The tool tries stronger levels until the file fits or the smallest level is reached.

Can I still select text after compressing?

No. Pages are saved as images to reduce the size, so keep your original file if you need the text.

Is this tool free?

Compress PDF is free to use. There is no signup and no watermark.

Are my files safe?

Everything runs inside your browser, so your files stay on your device and are never uploaded.
