Yes — every tool on this site is free, with no accounts and no hidden limits on regular use.
No. All tools process files directly in your browser using the PDF engines bundled with this site. Your files never leave your device.
PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), images (JPG/PNG) and HTML — see each tool for its accepted types.
Files up to 50MB are processed. Because everything runs locally, very large files only depend on your browser\u2019s memory.
There is nothing to delete — since files are processed in your browser, no copies are ever stored anywhere.
