v0.10.0How to use
- Choose one image.
- Press [Add area] to put a box in the middle of the photo. Drag the box to move it and drag the round handles on the corners and edges to resize it. With a mouse or pen you can also drag on an empty spot to draw an area.
- Pick the effect (pixelate, blur or solid cover) and strength for the selected area. Each area can use a different effect; add more areas if there is more to hide.
- With a keyboard, focus a box or handle and press the arrow keys (hold Shift for 10 pixels at a time), or type the position and size in the number fields below. If you make a mistake, press [Undo].
- Press [Apply effects], check the result and download it.
Example
To hide the licence plate in a car photo before listing it for sale, press [Add area], move the box over the plate, choose “Solid cover” and press [Apply effects]. To blur other people’s faces in a group photo, add an area for each face and use a high pixelate strength. To make the file smaller afterwards use Compress Images, and to keep only part of the photo use Crop Images.
Effects compared
| Effect | What it does | Good for |
|---|---|---|
| Pixelate | Splits the area into large cells, each painted with its average colour | Faces, people in the background, signs |
| Blur | Softens the area | Tidying the background, less sensitive parts |
| Solid cover | Paints over the area completely (no original pixels remain) | Licence plates, addresses, phone numbers, personal details in documents |
With a low strength, pixelation or blur can still reveal outlines or large text. Cover ID numbers, account numbers and addresses with solid cover, and zoom in on the result to check it again before sharing.
Supported formats, limits and privacy
- Input: JPG, PNG, WebP (HEIC only in browsers that support it). Output: JPG, PNG, WebP (only formats your browser can save are shown). One image at a time, up to 30MB per file, about 50 megapixels, and up to 50 areas.
- The result is saved at the same resolution as the original, and pixels outside the areas you mark are not changed. The effect changes the actual image pixels; it is not an overlay on the screen.
- Areas are placed on the photo with its saved rotation (EXIF orientation) applied, so the position on screen and in the result is the same.
- Strength (1–10) scales with the short side of the photo. For example, on a photo whose short side is 1,000px, pixelate strength 6 makes cells of about 38px and blur strength 5 has a radius of about 25px.
- Pixelate and blur only make the original harder to see; they do not guarantee anonymisation. Low strengths and small text can still be readable, so use solid cover when something must be hidden for certain.
- The original EXIF metadata (location, camera details and so on) is not copied to the result. ToolMoru details are written to every result file automatically: Software and CreatorTool (ToolMoru) plus the site address (toolmoru.com) in JPG and PNG, and CreatorTool (ToolMoru) plus the site address in WebP. Display information the browser adds when saving, such as the colour space, may remain.
- Everything happens in your browser; nothing is uploaded to a server.
Frequently asked questions
What is the difference between pixelate, blur and solid cover?
Pixelate splits the area into large cells and paints each cell with its average colour, and blur softens the area. Solid cover paints the area with the colour you choose, so none of the original pixels remain. For faces or licence plates that must not be recognised, raise the strength or use solid cover.
Can a pixelated photo be turned back into the original?
The saved file only contains the changed pixels; the original pixels are not stored separately. Weak pixelation or blur can still let people guess text or outlines, so use solid cover for important information. While editing, [Undo] reverts changes to the areas.
Is my photo sent to a server?
No. Reading the image, applying the effects and saving all happen inside your browser, and the original location (GPS) and camera details are not copied to the result.
