How browser-based processing works
When you select a document or image, the page reads it with browser technologies and established JavaScript libraries. The requested operation is completed locally, and your browser creates the downloadable result. Processing speed and the largest practical file size depend on your device, available memory and browser.
For confidential work, review the output before sharing it and keep an original copy. Some conversions can change image quality, page dimensions, transparency, fonts or searchable text. The instructions and frequently asked questions on each tool page describe the relevant trade-offs.
