If the text was blurred using a "Gaussian Blur" or "Pixelate" filter, it cannot be recovered using exposure adjustments. While advanced de-blurring tools can sometimes reverse light blurs, heavy pixelation permanently destroys the sequence of data.
A: Most support common formats like JPG and PNG, with some supporting WebP as well.

The underlying text is physically still in the image file. Your goal is to remove the colored "paint" overlay. | AI Object Remover: Use a "magic eraser" or "inpainting" tool like PicTextRemover or Magic Eraser to delete the colored box. | | Pixelated (Mosaic) Redaction | An area of an image that is blurred into a blocky, pixelated pattern, like small colored squares. | Potentially, with significant effort. True AI restoration is not possible, but the original un-pixelated text can be recovered if you have a similar letter pattern. This is complex. | Depix (Advanced Skill Required): This is a specialized Python tool, not a simple online service. It matches the pixel pattern to a supplied character map. | | Permanent Redaction (True "Flattened" Markers) | A solid, non-transparent black box or a marker that has been "flattened" into the image layer. This is what most people think of as "redacting." | No. The original text data is permanently destroyed and overwritten. AI can only "guess" what might have been there, not recover it. | AI Image Inpainting: This will generate a new , plausible-looking text, not the original one, by filling in the erased area. | unhide painted screenshot text online ai free verified
Highlighters are semi-transparent. Even if you swipe over the text three or four times and it looks completely black on your screen, the pixel data of the text underneath is still present in the file.
In short, the ability to But its effectiveness is directly tied to the quality of the redaction. If the text was blurred using a "Gaussian
Select the specific color channel that matches the marker (e.g., if the marker is blue, select the Blue channel).
