Questions

Can I compress several PDFs at once?

Yes: choose or drop them together. Each is compressed with the same level, and the ones that got smaller come back in one ZIP.

How much smaller will my PDF get?

It depends on what the PDF holds. Scans and documents full of photos often shrink by half or more. PDFs that are mostly text are usually small already and barely change; the tool tells you when that happens and doesn’t make the file bigger.

How do I get a PDF under 2 MB (or another limit)?

Choose Size limit, type the limit and compress. The tool tries stronger settings until the PDF fits and keeps the best quality that does. If even the smallest setting is too big, usually because most of the file is text and fonts rather than pictures, it says so and offers that smallest version. Splitting the PDF into parts with Split PDF is then the usual way to meet a limit.

Will the text still be selectable?

Yes. Only images are recompressed; text, fonts, links, bookmarks and form fields stay as they are.

Why don’t you use Ghostscript like other sites?

Ghostscript would have to run on a server (or be licensed under the AGPL). Here everything runs in your browser, so the document never leaves your device. The trade-off: fonts aren’t re-subset, which a server-side tool can sometimes squeeze further.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
