You want to share a screenshot, but it contains email addresses and names. Your photo includes a name badge you don't want to show.
Sumizushi is a free Mac app for redacting those parts before sharing. Drag to select the area you want to hide, then apply blackout, pixelation, or blur effects.
Use blackout for confidential information. Pixelation and blur can potentially be restored. You can also convert all your editing masks to uniform blackout at once.
"Find Candidates" reads text in images using your Mac, and suggests redaction candidates for email addresses, IPv4 addresses, and specified character strings. Only the candidates you confirm and approve become masks. Since detection misses are possible, visually verify the entire image before sharing.
Open a PDF and navigate through pages while placing masks over sections you don't want to show. When saving, a new PDF is created with all pages converted to images. In the exported PDF, text cannot be searched or selected. Confirm all pages before sharing to ensure nothing was missed.
Image and text processing happens on your Mac. The app never sends them externally. Save or copy images, save PDFs, and share them via Slack, email, SNS, and more.
It's free to use. No ads, subscriptions, or paid feature unlocks. In-app purchases are only optional tips to support the developer.
Compatible with macOS 14 and later.
