Private tools that never upload your files
These tools run in your browser, on your own device. Your PDFs, photos, recordings and text are never sent to a server, so nothing is stored and nobody else can see them.
65 tools
- Add Page Numbers to PDFAdd page numbers to a PDF at the top or bottom, in the centre or a corner, as 1, Page 1 or Page 1 of 10. Pick the text size and the number to start from, and leave the cover page unnumbered if you like. Landscape and rotated pages are numbered the right way up.
- Archive ConverterConvert RAR, 7Z, TAR, TAR.GZ and other archives to ZIP, TAR or TAR.GZ in your browser. Every file and folder name is kept, password-protected archives work if you have the password, and archives up to 500 MB stay on your device the whole time.
- Archive ExtractorOpen ZIP, RAR, 7Z, TAR, TAR.GZ and GZ files in your browser, see every file inside and download just the ones you need, or all of them as one ZIP. No software to install, password-protected archives work, and the archive never leaves your device.
- Base64 Decode and EncodeDecode Base64 to readable text, or encode text to Base64, as you type. Accents and emoji (UTF-8) and URL-safe Base64 work, and you can turn a file of up to 50 MB into Base64 or a data URL, or save decoded Base64 back as a file.

- CSV to TSV ConverterConvert comma-separated (CSV) data to tab-separated (TSV), or TSV back to CSV, as you paste. Quoted values, commas inside values and line breaks are handled correctly, so nothing shifts into the wrong column. Semicolon and pipe-separated files work too.
- Delete PDF PagesRemove pages from a PDF by typing their numbers, like 2, 5-7, then download a new copy without them. Blank pages, old versions of a page or a whole section go in one step, and the removed pages are really gone from the new file, not just hidden.
