How it works

Three simple steps.

Select the PDF you want to make smaller.
Choose Recommended for good quality, Strong for the smallest file, or a size it must fit in, such as 200 KB or 2 MB.
Download the smaller PDF. Pages keep their size. Text stays sharp, except when a very small size can only be reached by saving pages as pictures.

Security and privacy

Your file is processed right here in your browser.

The code that does the work runs in your browser, so your document never leaves your phone or computer. Nothing is uploaded and nothing is kept after you close the page. You can check: once your file is open, switch on airplane mode and the tool still finishes.

Frequently asked questions

How much smaller will my PDF get?

It depends on what is inside. PDFs with scans and photos usually get much smaller, because the pictures are made smaller. A PDF that is mostly text is often small already.

Can I make a PDF smaller than 100 KB or 200 KB for an online form?

Yes. Choose a size from the list, or type your own in KB or MB, from 20 KB to 100 MB. You get the best-looking version that fits.

Will the text stay sharp?

Yes. Only the pictures inside the PDF are made smaller; text and lines are not touched. Only when a very small size cannot be reached that way are whole pages saved as pictures, and the page tells you when that happens. Then text can no longer be copied.

What if my PDF cannot be made smaller?

Then you get your original file back, unchanged, so nothing is lost.

Why does it say my size is too small?

A PDF with many pages cannot always fit in a very small size and stay readable. Choose a bigger size, or split the PDF and send fewer pages. The message shows the smallest size that is possible.

Is my file uploaded anywhere?

No. Your file is processed by your own browser on this device. It is never sent to a server, and nothing is kept after you close the page.

Can I use a password-protected PDF?

PDFs that only block copying or printing open normally. A PDF that needs a password to open cannot be used here: remove the password with the app that set it, then try again.

Is it free? Do I need an account?

Yes, it is free and there is no sign-up.
