How it works
Images in the document are resampled and recompressed locally, and the file structure is rewritten without unnecessary objects. Text stays searchable.
- 01Select the file
Drag the PDF into the tool area or click to choose it. It stays in your browser's memory only.
- 02Local processing
The PDF engine runs on your computer, in JavaScript and WebAssembly. Nothing is sent; you can watch the Network tab.
- 03Download the result
The finished file is saved straight from the browser to your disk. Close the tab and no copy remains anywhere.
Frequently asked questions
How much smaller does the file get?
It depends on the content. Scanned, image-heavy documents usually shrink a lot; text-only PDFs are already small and change little.
Does image quality drop?
You choose the level. At moderate levels the difference is not visible on screen or in ordinary printing.
Is it suitable for filing systems with size limits?
Yes, that is the most common use: reducing the file to fit a system's limit without turning the document into an image.
