Compress a PDF

Free toolsFree · No sign-up · Private files

Choose your PDF and a compression level. Each page is recompressed as an image: the size drops a lot, but the text is no longer selectable. Your files stay in your browser: nothing is uploaded to a server.

How to reduce the size of a PDF

Add your PDF, pick a level (strong compression, balanced or high quality) and download the lighter file. The tool shows the size before and after.

Why is a PDF so heavy?

PDFs made from scans or photos contain large high-resolution images. That is what pushes them to dozens of MB, beyond the limit of most email services and online forms.

What this tool does (and its limits)

Each page is recompressed as a JPEG image: the size drops a lot, but the text is no longer selectable and the layout is fixed. That is perfect for scans and documents to print or send. For a PDF that must stay editable or searchable, keep the original.

Private compression

Everything happens in your browser: your file is not uploaded to any server.

Frequently asked questions

Is the text still selectable after compression?

No. Each page is turned into an image, which cuts the size but removes selectable text. Keep your original if you need it.

Why did my PDF get bigger?

An already optimized PDF can grow. In that case the tool tells you and downloads nothing: keep your original file.

Is my file uploaded online?

No, everything happens in your browser.

How do I compress a PDF to send by email?

Choose “Strong compression”, check that the file is still readable, then attach it to your email.

How do I compress a PDF without losing quality?

Choose “High quality”: the size drops less, but the visual quality stays very good.
