DESIGNED FOR CLARITY
From screenshot to explanation.
A practical workspace for support teams, designers, developers, teachers and anyone sharing visual instructions.
01 / CAPTURE
Start anywhere
Upload a screenshot, drop an image, paste an image from your clipboard, or capture a tab, window or display when your browser permits.
02 / ANNOTATE
Make the point
Combine arrows, shapes, highlights, text and numbered pins. Select and rearrange annotations, with undo and redo.
03 / PROTECT & EXPORT
Share with confidence
Crop, obscure or solid-redact details, then flatten everything into an exported PNG, JPEG or WebP. Opaque redactions always cover later effects.
Frequently asked questions
Can I annotate the screen live over other apps?
No. A web page cannot draw over other desktop applications. This tool captures a still frame from a browser-approved screen-share session, stops screen sharing, and lets you annotate the screenshot in the page.
Are screenshots uploaded to PixelOkay?
No. Imported images, screenshots and annotation processing stay in your browser. Editable projects download to your device; the tool requires no account or backend.
Is blurring enough to hide passwords?
No. Blur and pixelation can sometimes be reversed or inferred. Use the opaque Redact tool and export a flattened image. Never share an editable project containing sensitive source material.
Why is screen capture unavailable?
Screen capture needs HTTPS or localhost, a supported browser and a user-approved tab, window or display. Some mobile browsers do not support this API. You can always upload or paste an existing screenshot instead.
Can I continue editing tomorrow?
Choose Save project to download a PixelOkay project (.json), then Open project to restore it. A regular project contains the original source image. If you have used solid redactions, choose Save safe project instead to permanently bake those redacted regions into the embedded raster of a separate editable copy. Blur and pixelate still do not conceal secrets.
Using Screen Annotation Studio
Open a raster image or explicitly capture one screen frame, then add annotations. Use opaque Redact for sensitive areas and choose a flattened image or the supported safe project workflow when sharing.
This is an image annotation workspace, not a live desktop overlay or video recorder. Blur and pixelation are not secure concealment. Regular project JSON retains the original image; safe project copies bake opaque redactions only, not blur-only areas. Capture and clipboard APIs depend on browser permissions and secure context.
Choose an annotated image or the appropriate project copy
Flattened image: share rendered annotations after checking all visible content.
Regular project JSON: preserve editing data, including the original image beneath privacy annotations. Treat this file as containing the source material.
Supported safe project copy: bake opaque Redact regions into the image. Blur-only and pixelated areas are not baked as opaque redactions.
Practice: mark up a fictional screenshot
Open a test image containing a clearly fictional label such as DEMO-ID.
Add an arrow and an explanation, then place an opaque Redact region over the fictional label.
Choose the export appropriate for the recipient and review it. Keep the regular editable source separately when it should not be shared.
This is an authored inspection exercise, not a redaction test or a guarantee that an output is safe to distribute.
Screen annotation questions
Does blur or pixelation securely remove information?
No. Use opaque Redact for the areas you intend to cover and inspect the whole output. Regular editable projects still retain the original image, even where annotations conceal it visually.
Can this annotate my desktop continuously or export a PDF?
No. It edits an image or one explicitly captured screen frame. It is not a live operating-system overlay, video recorder or PDF export tool. Screen capture and clipboard access depend on supported browser permissions.
