Blur a Signature in Any Image

Cover a handwritten signature before you share a contract photo, receipt, or form scan.

🔒 No upload · Runs in your browser · Instant download
Signed documents photographed for email or chat often expose a signature you do not want public. HideShot lets you draw over the ink with blur, pixelate, or a solid black box, then export a PNG that keeps the rest of the page readable. Everything runs locally in your browser.

Blur Signature Online — Targeted Redaction for Signed Photos

When you blur signature online content, you are hiding a biometric-style mark that can be copied or reused. A photo of a lease, medical form, or delivery receipt may only need one line obscured while the rest stays visible for context. HideShot uses region selection instead of whole-image filters so addresses, totals, and labels remain sharp.

Blur discourages casual copying but is not as strong as a black box for high-risk documents. For notarized papers, loan packets, or anything that could enable fraud, switch to Black Box mode in the toolbar. Pixelate sits in the middle — useful when you want obscured strokes without a flat rectangle.

Because processing stays on your device, you can upload a scan, blur the signature, undo, enlarge the selection, and download without sending the file upstream. Paste from clipboard works for quick screenshots of PDF viewers or mobile gallery images.

Frequently asked questions

Can I blur only the signature and leave the rest of the document visible?

Yes. Draw a rectangle, oval, or lasso around the signature area. HideShot redacts only that region and leaves surrounding text untouched.

Is blur enough to stop signature forgery?

Blur reduces readability for normal viewing but is not forensic erasure. For legal or financial documents, use Black Box mode for stronger concealment.

Does HideShot upload my signed document?

No. Images load into a browser canvas on your machine. Nothing is sent to HideShot servers for editing.

Can I paste a screenshot of a signed PDF page?

Yes. Copy the image and press Ctrl+V (Cmd+V on Mac) while the page is open, then redact the signature and download PNG.
