Compress PDF: reduce the file size
To compress a PDF without removing its text, only the photos change: each goes back to the resolution it is shown at on the page. A 3.000-pixel photo printed 10 cm wide has 762 ppi; at the recommended level of 150 ppi it comes out 591 pixels wide. You can ask for a final size, such as 1 MB, without uploading the file.
The PDF never leaves your device
