About this tool: Compress PDF
Compress PDF documents in the browser by rasterizing pages at controlled resolution and JPEG quality. This is especially useful for scanned PDFs; selectable text and form fields become image content in the compressed output.
The workflow keeps the document task focused on the selected PDF pages or settings and produces a downloadable result when processing succeeds.
PDF Compressor is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
PDF Compressor reads and modifies the selected document in the browser with PDF libraries loaded only on PDF workflows; the build does not send the document to a NexterHub upload endpoint.
Practical example
A scanned 5 MB PDF may shrink substantially with recommended compression, while a text-heavy PDF may shrink less.
Important notes
Keep an original copy of important documents and review page order, quality and output size before using the new PDF.
Privacy & processing
In the current NexterHub build, primary PDF processing runs in the browser and is not sent to a NexterHub upload endpoint.
