Questions
Will the text stay sharp?
Yes. Text, fonts and drawings are kept as they are; only images are made smaller. Pages are turned into images only if you allow it to reach a very small size.
What if my PDF cannot get under the size I need?
You get the smallest version we could make and a plain explanation, for example that the fonts alone are larger than the limit. We never say a target was met when it was not.
Why is 200 KB shown as about 195 KB on my computer?
Some computers count 1 KB as 1,024 bytes. We aim under the stricter reading (1 KB as 1,000 bytes), so the file passes either way.
Does it work with password-protected PDFs?
Yes. Enter the file's password when asked; it is used on this device only. The new file is not password-protected.
Are my files uploaded anywhere?
No. Your browser does the work on this device, and the tool keeps working offline once the page has loaded. Nothing is sent to a server.
