Before you start
What are the file limits?
One PDF up to 50MiB. Basic compression supports 300 pages; strong compression supports 30 pages and 16 megapixels per rendered page. Processing stops after 45 seconds. Your device may require smaller files.
Where are my files stored?
File contents are processed in browser memory, without uploads or persistent app storage. Closing or refreshing the tab clears the work; downloaded files remain on your device.
Will the original file change?
A new PDF is created, leaving your originals unchanged. Check important documents before use. Image PDFs do not include OCR or text recognition.
