Compress a PDF

Make a PDF smaller, for example to fit an email or a form upload limit. Pictures inside are shrunk; text stays sharp.

Your files stay on your device. Nothing is uploaded: the PDF work happens inside your browser, so not even mwai can see your files.

Questions

Are my files uploaded anywhere?

No. This page loads the PDF tools into your browser once, and then works on your file right there on your phone or computer. The file is never sent to mwai or anyone else. Many other PDF websites upload your file to their servers; this one does not.

How much smaller will my file get?

It depends on the file. Scanned documents and PDFs full of photos often shrink by 50 to 90 percent. A PDF that is mostly text is already small and may not shrink much.

Will the text get blurry?

No. Only pictures are re-saved at a lower quality. Text and drawings stay sharp.

Some forms need a file under 200 KB or 1 MB. Can this help?

Yes. Start with Balanced. If the file is still too big, try Small file, or move the quality slider lower.

Is it really free?

Yes. There is no sign-up, no limit on how many files you use, no watermark added and no ads.
