Edit and blur a screenshot

On this page, yes: the pixels are overwritten before the file is written, so the original characters are not in the download. Be aware that a light blur over small text can still be partially readable, and blurred numbers have been recovered before. Pixelation replaces each block with a single flat colour and is the stronger of the two here; for anything you truly cannot afford to leak, the redaction tool's solid block removes everything.

Yes. Copy a screenshot to your clipboard and paste onto this page, and it loads the same way a dropped file does. Nothing about the paste route sends the image anywhere - the clipboard content is decoded by your browser exactly like a file you chose.

Choose the numbered step tool and add one for each thing to click. The numbers are assigned in the order you add them, so adding them in the order a reader will follow gets it right the first time. Each one can then be moved with the arrow keys or the position controls, and the list underneath shows which is which.

Yes, as a side effect. The image is rebuilt from raw pixels, so anything stored in the file's metadata - which on some systems includes the machine name or the capture time - is not carried into the output. If metadata is your main concern rather than what is visible, the metadata remover addresses it directly and tells you what was there.

No. Screenshots are exactly the kind of image where that question is not academic, so it is worth being precise: the file is decoded, edited and re-encoded by your browser on your device, no request carrying it is made or possible, and a content security policy the browser enforces blocks this page from reaching another domain at all.
