Navigate to pdfeditor.onl/compress-pdf in Chrome or Edge on Windows 10 or 11.
Click the upload area or drag the PDF from File Explorer into the browser window. Select Good or Strong. Click Compress. Download the reduced file.
Tip: Drag and drop from File Explorer directly into the browser tab — the fastest way to upload on Windows.
No. Chrome or Edge on Windows handles everything through pdfeditor.onl — no installation, no admin rights needed.
Yes — completely free in any modern browser on Windows.
