How much smaller will my PDF get?

It depends what is in it. Scanned or image-heavy PDFs shrink the most, sometimes dramatically; a text-only document is already compact and will change very little.

Will the text still be selectable afterwards?

Yes. The text layer is preserved rather than flattened to an image, so the compressed file stays searchable, copyable and readable by a screen reader.

Compress a PDF

Shrink a PDF so it fits an email or upload limit, without sending it to anyone. Compression happens in your browser and the original stays untouched.

Runs entirely in your browser — your file is never uploaded.
