Shrink PDF file size by recompressing embedded images and stripping unneeded data.

FAQ

Common questions

Are my PDFs uploaded anywhere?

No. Your PDF is loaded, compressed, and saved entirely in your browser. Nothing is uploaded.

How does the compression actually work?

TinyUtility recompresses embedded JPEG images at your chosen quality level, downsamples oversized images, strips unnecessary metadata, and rebuilds the file using optimized object streams.

Why didn't my PDF get much smaller?

PDFs made mostly of text and vector graphics, or that use image formats other than JPEG, have little left to compress. TinyUtility never fabricates savings — if a file is already efficient, it says so.

Can I compress a password-protected PDF?

Not yet. Password-protected PDFs are not supported — remove the password first, then add the file again.

Which compression level should I choose?

Medium is recommended for most files. Choose Light when image quality matters most, or Strong when file size matters most.
