Compression level

A balanced drop in image quality for a clearly smaller file.

What compression changes here

Image-heavy PDFs get smaller because the embedded photos are re-encoded at the level you choose, and the strong level also rebuilds large images at a smaller size. Text, links, and page order are never rasterised, so copy and selection still work.

Questions about this tool

Does compression affect text?

Text is copied rather than rasterized, so it remains selectable.

Frequently asked questions

What do the three compression levels change?

Light re-encodes embedded photos gently, Medium drops their quality further, and Strong rebuilds them at a smaller size as well as a lower quality. The level you pick decides how much detail the pictures keep.

Will the text still be selectable after compressing?

Yes. Only the images inside the PDF are rebuilt. Text, links, fonts, and page order are untouched, so copy and search keep working in the smaller file.

How much smaller can my PDF get?

It depends on what is inside. Scanned pages and photo-heavy documents shrink the most, while text-only PDFs are usually already small. The result screen shows the before and after sizes so you can decide.

Why did my PDF barely shrink?

Files with little or no embedded image data have almost nothing this tool can rebuild. Vector drawings, fonts, and text streams are already compact, so the tool reports that the file is already as small as it can make it.

Is the document uploaded?

No. The PDF is opened, re-encoded, and saved on your device. Nothing is sent to a server, and the tab does not keep a copy.
