No matter if you want to make a background transparent (PNG), add a white background to a photo, extract or isolate the subject, or get the cutout of a photo - you can do all this and more with remove.bg.

If you want a special color to become transparent, you use the Color Replacer Tool in Draw/Impress > Tools. It has a color picker to fetch the color from the image, but is has no preview. Therefore you might need the undo function. When you are done in Draw or Impress, you can copy the picture over to Writer.


Presumably your are referring to this feature of MS Word. There is currently (as of v4.0) no equivalent function within Writer. You will need to edit the image externally e.g., using LO Draw, GIMP, Photoshop, etc. This Ask LO thread deals with a similar issue, albeit in reference to LO Impress.


I'm working on a project where I need to make modifications in more then 500 images to give outerglow on hover effect. I will need to modify each image to give the outer glow. It will be a very time consuming task.


If you have to do this to 500+ images, what I would do is great a transparent PNG of the inverse of the bottle with feathered edges around the bottle and lay that over a DIV with the background color under it and the bottle image in between. This will make the solid background color appear to fade out into the inverse bottle PNG and all you would have to do to change the glow color is change the value of the CSS.


I have two img elements and I want the first image.png to go behind the transparent image.png. I have tried a lot of different things (z-index, transparent background color, rgba background color, positioning absolute and relative, nesting one in a div, making them both divs). Right now i've been trying to use a transparent .png image. The image .png is actually behind it, but it still shows through it. Please help.






Create a wrapper DIV for your two images. Set that wrapper DIV's to position: relative so we can use absolute positioning on one of the images it contains. By doing this we prevent the absolute positioned image from potentially aligning itself elsewhere in the page, like the upper left corner of the browser window.


To have the image appear as if it is coming out of the base layer image simply adjust the position of the image inside the wrapper DIV. For the jsFiddle simply play with the value of top in .mask img.


Put them both in a parent container. Make the parent have position: relative and put both images having position:absolute. That way they will stack.(Something like that that I didn't check The order of img's could be wrong - play around a bit.


Remove background from images of humans, animals or objects and download high-resolution images for free. You can also edit photos as you like. It also supports developers in removing image backgrounds through API.


I'm dealing with an issue I've never had before. I use transparent images made on photoshop on an Indesgin file. On the PDF file everything is great. But when I print the page, all the backgrounds get black and not transparent as it's supposed to be.


This online browser program replaces any solid color and its close color tones in a Portable Network Graphics (PNG) photo or picture with transparent pixels. To match similar color tones, enter the similarity percentage in the settings. By default, 30% similar color tones are matched but you can change it as you see fit. For example, if the color that you're removing is red, then it will also remove cherry-red, rose-red, wine-red, and similar shades of red. If you remove the color and the edges of the image still have a pixel or two of the old color, you can refine the edges and smooth them by enabling the "Smooth Edges" checkbox. This option makes the pixels on the border between transparency and opacity semi-transparent. By increasing the smoothness radius, you can remove more pixels from the edges and make PNG clearer. Also, you can interactively click on the input PNG to instantly remove any color and its tones. For example, if you click a green pixel, then all greenish pixels will be made transparent. This way, you don't have to know the name or code of the transparent color and you can make the PNG transparent by simply clicking on the color in the PNG. Additionally, we have added an option "Match Outer Pixels Only", which lets you remove only those areas that are in contact with the outer edges of the image. For example, if you have a PNG of a donut on white background, then the white color will be both inside and outside of the donut. If you select this option and try removing the white color, then only the area around the donut will disappear but the inside of the donut will remain opaque. Png-abulous!


In this example, we convert a non-transparent PNG signature into a transparent digital signature. The input PNG is the signature of Steve Wozniak (co-founder of the Apple computer company together with Steve Jobs). As the input PNG isn't transparent, we remove the background by entering the color "white" in the transparent color field. To make sure we remove gray shades around the edges of the signature, we set the percentage of similar colors to 12%. Also, we refine the pixels around the edges with a radius of 1, making them translucent. In the output, we get a clean signature that can be used to sign electronic documents without the need to print and scan them. To use the transparent signature, import it in your Word or PDF document, overlay it on the signature field, and you'll get a signed document.


In this example, we load PNG text written in Bungee Shade font that says "New York City" in the input field and create transparent text from it by removing its background. We remove only the color around the letters and leave the filled areas inside the letters white. We activate the option that matches the pixels around the outer edges of the text and to make the background transparent, we specify the hexadecimal color code "FFFFFF", which corresponds to the white color. Also, as the text is in raster format, there are darker pixels near white ones, and to remove them as well, we specify 18% fuzzy matching of white tones. To get rid of the remaining white pixels around the letters, we make them semi-transparent using the edge smoothing option. The resulting outline of the font can be used as a watermark on photos and pictures or digital documents.


In this example, we visually check if a pixel maze is passable. We upload a randomly generated PNG of a maze with blue paths and black walls and remove only those blue pixels from it that are reachable from the outside of the image. The program finds all open paths in the maze and removes the blue color from them. The closed areas of the maze remain blue and we can see that this maze is not solvable.


This just randomly happened out of no where and I have no clue why. When I open other files with transparent backgrounds I've done in the past those open just fine but when it's copied and pasted from online the background is turned black.


I tried that, using a PNG file with transparency, although the transparent areas appeared in the editor after import, nothing was created there after pressing generate. Anyone ever tried this and succeed ?


I am using Elementor with the Astra theme for my website and I am trying to add a transparent png image to an image box on a coloured background. However, everytime I add a picture it displays a White background even though it is supposed to be transparent. I have tried with multiple png images but they all show a White background. My box shadow is disabled for the image.


The first CSS block is similar to the code in Example 1. In addition, we have added what should happen when a user hovers over one of the images. In this case we want the image to NOT be transparent when the user hovers over it. The CSS for this is opacity:1;.


When using the opacity property to add transparency to the background of an element, all of its child elements inherit the same transparency. This can make the text inside a fully transparent element hard to read:


I'm designing this animal-type creature, and want to add a transparent .png image to its face with the face features (object has a subsurf).On the left is the image with the features, on the right is the part of the object where I want it to be.


I tried to import the image as a plane, but matching the shape of the plane with the face didn't work, and the lines of the face left shadows on the head, and could be seen as a different object from some angles (although it's the closest I've gotten yet). It looked like this:


Is it something I have to go into Nodes for? I'm kind of stuck here. Creating a new material and applying it is simple, but applying a material that is an image is a bit more complex it seems... Ideally, I would reproduce the same technique for the adhesive bandage on its arm (seen on the right of image 1).


An image with an alpha channel, is composed of two different elements. The RGB (Red, Green and Blue channels, or color information), and a black and white channel called "Alpha" channel. White parts determine what is opaque, and black areas what most people call "transparent".


If you want to use the color information of the image over the color of a given shader, in a way that all other properties of the shader are homogeneous, then use a color mix node, and have the mask be the factor for the color of the shader. Plug Alpha to the Fac of the mixRGB and the resulting mix to the shader's color input.


In newer versions of blender the Principled shader has an input for Alpha. If you plug in the alpha channel of the image directly to the alpha input of the shader, you will get a fully transparent object, except in the areas controlled by the alpha channel. In this case you don't need an additional transparent shader.


FWIW, this appears to be a Photoshop problem, not a browser or OS problem. On both OS X and Windows, I can copy a PNG image with transparency from Chrome (and also Safari on OS X) and paste it into Illustrator or other applications and have it maintain transparency. Photoshop alone is to blame.
