Private File & Image Tools guide
Uploading a personal document or photo merely to edit it can be an unnecessary privacy tradeoff. Supported file tools read the file and create the output in your browser.
Very large files may be limited by device memory. Keep the original and open the result to verify page order, completeness and image quality.
Before you start
- Keep a separate copy of every original file.
- Re-encoding JPEG can introduce a small quality loss.
- Check page order and completeness after merging PDFs.
