How to use this tool
Choose or paste a JPG, PNG or WebP. Draw rectangles over private details, or add a mask using exact pixel coordinates. Select a mask to move it, edit its size or delete it. Use opaque black or white for secrets. Review the flattened export, then download PNG, JPG or WebP.
Quick steps
- Open a static image or paste a screenshot. No upload is needed.
- Draw opaque masks or enter precise pixel coordinates. Inspect every private detail.
- Review the actual flattened file and download PNG, JPG or WebP.
Practical tip
Cover the complete sensitive area with a little extra margin. Pixelation is a visual effect, not dependable removal of secrets. Check every corner, reflection and notification in the exported preview. Originals and edit history stay in this tab only.
Common questions
How do I black out text in a screenshot?
Open the image, keep Opaque black selected and drag a rectangle over the complete text. Add a margin around the characters, review the output and download. The exported file contains flattened pixels, not movable covering boxes.
Can someone remove the black boxes from my downloaded image?
An opaque mask replaces the covered pixels in the flattened export; the original pixels and edit history are not included. This does not protect information you missed or details inferable from context. Share the exported file rather than the original.
Is pixelation safe for passwords or account numbers?
No. Small blocks and predictable text can still reveal information. Use opaque black or white for confidential details; pixelation is available for cosmetic obscuring only.
Are my images uploaded or saved?
The editor processes images locally and does not upload them or save them in browser storage. Reloading clears the image and history. Normal website asset requests still occur. Download your finished image before leaving.
Does it remove EXIF and GPS metadata?
The output is encoded from a new canvas without copying source EXIF, GPS or other source metadata. Visible text, landmarks and reflections can still reveal information. The output filename is generic by default.
Can I use it on a phone or without drawing?
Yes. Draw with a finger, then use the numbered mask list and pixel-coordinate fields to adjust. Add coordinate mask provides a keyboard-accessible alternative to drawing. Zoom and scroll help with small details.
Can I reuse the same redaction areas?
Export a mask-layout JSON to reuse rectangles on images with exactly the same pixel dimensions. Layouts contain coordinates and styles, not the photo. Import adds masks to the current image. Always inspect alignment on each new screenshot.
Which files can I use?
Static JPG, PNG and WebP, up to 20 MB and 20 megapixels, with neither dimension above 10,000 pixels. PDF, SVG, HEIC, RAW and animated images are not supported. Export a static image first.
Does it find sensitive information automatically?
No. All masks are manual. There is no face detection or OCR, and no promise that every private detail has been found. Review the full output before sharing.
