SnapSeal – Full Page Screenshot & Editor

Capture full page screenshots. Edit, redact, compare and protect images with a password. Free and local.

SnapSeal App is a free full page screenshot extension with a built-in editor and password protection for images. Capture an entire scrolling page, the visible area, a single element or any region you select, annotate it, redact private details, then encrypt the image so nobody can open it without the password. No account needed. Your screenshots and passwords never leave your device. FULL PAGE SCREENSHOTS IN ONE CLICK • Whole page. The extension scrolls the site for you and stitches one long screenshot from header to footer. • Visible area. Instantly capture what is on your screen right now. • Select an element. Screenshot a single block, table or scrollable area inside the page. • Crop. Drag over any part of the screen and save only that region. • Save as PNG, JPEG or WebP, with adjustable JPEG quality. • Keyboard shortcuts: Ctrl+Shift+1 visible area, Ctrl+Shift+2 whole page, Ctrl+Shift+3 select element, Ctrl+Shift+4 custom region. On Mac, use Cmd instead of Ctrl. Shortcuts can be changed. SCREENSHOT EDITOR Every capture opens in an editor, so you can polish it before sending: • arrows, rectangles, brush and text labels; • the Redact tool covers emails, phone numbers, order IDs, API keys and anything else that should stay private with a solid block; • crop, zoom, undo and redo; • copy to clipboard or download with one click. PASSWORD PROTECT ANY IMAGE This is what sets SnapSeal apart from other screenshot tools. Encrypt any capture or any image from your computer: • the image is encrypted with AES-256-GCM right in your browser; • the result is a PNG that reveals nothing without the password: in the extension it looks like random noise, and on the SnapSeal website you can hide the encrypted image inside an ordinary picture; • cover mode offers 29 ready-made pictures (cat, dog, tiger, owl and more), or you can upload your own, so the file looks like a normal photo while the original stays encrypted; • send the file as an attachment by email or messenger and share the password separately; • the recipient opens it on the SnapSeal website or in the extension, enters the password and sees the original. They don't need to install the extension or sign up; • supports PNG, JPEG, WebP and GIF: up to 50 MB in noise mode and up to 8 MB in cover mode, with a password of at least 12 characters. It's a simple way to send screenshots with bank details, logins, documents, internal reports or private chats. Note: the password cannot be recovered, and compressing or resizing a protected PNG breaks it, so always send it as a file. SCREENSHOT HISTORY AND COMPARISON • Every capture is saved to a local history you can search by page title. • From the history, copy, download or edit a screenshot, or reopen the source page. • Pick two captures and compare them as an overlay, side by side or as a diff. Spot what changed on a site after a layout fix, a price update or a release. WHO IT'S FOR • QA testers and developers: bug reports with full page screenshots and annotations. • Designers and marketers: full captures of landing pages, version comparisons, client reports. • Support teams and managers: screenshots with customer data redacted. • Anyone who shares sensitive images and wants to keep them away from the wrong eyes. PRIVACY • Capture, editing and encryption all run locally. Your images are never uploaded. • No account or sign-up required. • History is stored in your browser on your device, and you can clear it at any time. • The interface is available in 51 languages. FAQ How do I take a full page screenshot with scrolling? Click the SnapSeal icon and choose "Whole page", or press Ctrl+Shift+2. The extension scrolls the page and saves it as a single image. Is SnapSeal App free? Yes. Screenshots, the editor, history, comparison and password protection are all free, with no sign-up. How do I password protect an image? Open a capture and click "Protect", or upload any image in the image protection section. Choose a password of at least 12 characters, and the extension creates an encrypted PNG. How can someone open a protected image without the extension? The recipient opens the unlock page on the SnapSeal website, pastes or selects the PNG and enters the password. No extension needed. Can the protected file look like a normal picture instead of noise? Yes. On the SnapSeal website, choose cover mode and the encrypted image is hidden inside an ordinary picture. Use one of 29 built-in covers or upload your own. Everyone sees the cover, but only the password reveals the original. How secure is the encryption? SnapSeal uses AES-256-GCM. The image and password are processed only on your device and are never sent to a server. Without the password the file cannot be opened, and the password cannot be recovered. Can I hide personal information in a screenshot? Yes. The Redact tool in the editor covers the selected area with a solid block, and that information is gone from the saved file. What formats can I save screenshots in? PNG, JPEG and WebP. Choose the format and JPEG quality in the settings. Can I compare two screenshots? Yes. Select two captures in the history and switch between Overlay, Side by side and Diff. Install SnapSeal App to capture full web pages, mark them up and send private images behind a password.
