How to easily remove backgrounds from your signature

If you’ve ever used the internet—and if you’re reading this then that’s a yes—chances are you’ve been asked to sign a digital document. If the platform you’re using doesn’t have a dedicated signature tool, then you’ll likely need to upload an image of your written signature. 

When uploading your signature, it helps to have a transparent background that allows your image to blend in seamlessly with the document you’re signing. Unfortunately, digital images don’t come with transparent backgrounds by default, meaning you’ll have to remove it yourself. 

This guide will explain how to remove background from your signature using seven popular tools. We’ll also walk through how to add those signatures to common workplace software.

Why remove backgrounds from signatures? 

Having a digital copy of your signature makes it easier to quickly sign and send official documents like contracts, invoices, and other legal documents. They can also be used to personalize creative designs, social media posts, email signatures, watermarks, and other digital stamps. The list of reasons to have a digital signature is long, so the image file you use should be clean and high quality. 

Removing the background from your signature image ensures that you can use it for virtually anything. 

The practical benefits include: 

  • Professionalism. A transparent background makes your signature look clean and polished, giving a more professional appearance on documents, presentations, and branding materials.

  • Versatility. Transparent signatures can be used seamlessly across different platforms like Word, PDF, and Google Docs without any visible background clashing with the document.

  • Ease of use. You can easily overlay a background-free signature on various media, from contracts to marketing materials, without worrying about unwanted white boxes or borders.

  • Brand consistency: A consistent, clean signature across all platforms enhances brand identity, making your materials look cohesive and trustworthy.

  • Simplicity: Removing backgrounds saves time, allowing you to instantly apply your signature without needing to adjust or edit the image each time.

Like with images, having a copy of your signature without a background increases the number of places you can use it, without having to repeatedly make edits to your image file. The trick is finding the right tool to use.

How to remove the background from a signature 

There’s no shortage of tools available for removing the background from your signatures. The key is finding one that’s quick and easy to use, and that integrates seamlessly into your daily workflows. 

Here are seven tools to help you remove the background from your signatures. For these examples, we’re going to start with this original signature file.

How to remove background from a signature online for free with Photoroom

First on our list of tools is Photoroom. This AI-photo editing tool is available as a mobile app for Android and iOS or through your web browser as a desktop application. The basic version of Photoroom is free, and allows you to remove the background of uploaded images and turn it transparent. 

Here’s how to remove the background from a signature for free with Photoroom. 

First, write your signature on a white piece of paper and snap a photo of it. Save that image to your device. Then, follow the steps below. 

Note: This process also works if you have an image on your desktop or device already. 

How to remove the background from a signature on the Photoroom mobile app

Open the app and tap “+ Start from Photo”. Select your image from the camera reel.

Photoroom will upload your photo into the application and automatically remove the background from the image. You can then select what you want to replace the background with. 

In the Background options menu, select Transparent.

Once done, tap Export > save to Gallery. This saves the image to your device. Here’s what out file looks like now.

You can then import this image file into your future documents.  

How to remove the background from a signature on the Photoroom desktop app

Navigate to the Photoroom web app on your computer and login to your Photoroom account. 

Click “+ Select a photo” and find your image in your files. Click “Open”.

How to remove background from a signature in Photoshop

Next on our list is Photoshop. This powerful desktop photo editing tool allows you to make simple to advanced edits to your images, including background removals. There are a few different ways to make a background transparent in Photoroom. 

Here’s the easiest one for signature files. 

Open Photoshop on your computer and add your signature by opening your image file in the application.

In the top ribbon, click on Select and then Color Range.

In the Select dropdown, make sure the drop down is set to Sampled Colors.

Your mouse cursor will become an eyedropper. Sample the color of your signature by clicking on part of the text. This captures the exact hex code for your signature. 

Set Fuzziness to 200 (max).

Note: The Fuzziness setting controls how wide a range of colors is in the selection, and increases or decreases the amount of partially selected pixels (gray areas in the selection preview). Setting a high Fuzziness value, as we do here, increases that range. 

Click OK. Photoshop will now have selected just your signature text. 

At the bottom of the screen, click on Layer Mask. This will remove all parts of the image that are not your signature (i.e.  the background). 

Once done, click File > Export > Quick Export as PNG. Or, you can click Export As and change the format in the file dropdown to PNG and hit export. 

Choose a location for your file and click Save.

How to remove background from a signature in Word

Word also gives you some basic tools for removing the background from your signature files. Of course, Word is not an image editor, making these capabilities limited compared to Photoroom or Photoshop. But, this tool is useful if you want to contain your workflow to just one application.

Here’s how to remove the background from your signature in Word. 

Add your signature to Word. In the top ribbon, go to Insert > Pictures > This Device. This will open a File Explorer window where you can then select your signature file. Click insert.

Note: Ideally, the signature should be in black ink on a white background to make this process easier.  

Click on the Image and ensure you’re in the Picture Format tab in the top ribbon. On the left side of the screen, click the Corrections drop down > Picture Corrections Options. This will open a side menu

In the side menu, perform the following steps: 

  • Increase Sharpness to 100% to ensure the edges of your signature of crisp 

  • Increase Brightness to about 50% (until the background becomes white like the background of the Word document

  • Adjust the contrast up or down as needed to make the signature itself as clear and dark as possible

Once you’re happy with the image, right click > Crop. Drag the crop sliders so that they’re tight to your signature. This removes the extra background that you do not need.

To move the image around freely in the Word document, right click again, click Wrap Text > select the option that works best for your document. Freely move the image to your desired spot. 

Lastly, you can also right click > Save as Picture and then save a local version of that file for use in other documents. Change the file type to JPG, PNG, or whatever works best for your needs. 

How to remove background from a signature in Paint

Paint is another useful tool for removing signature backgrounds and comes stock with all Windows desktops. Here’s a simple way to remove backgrounds using this application. 

Open Paint on your desktop. Click on File > Open and choose the image you’d like to remove the background from.

Once you see the image show up, click the dropdown arrow under Selection > Transparent selection. 

Now use the free-form selection tool to select the area item you want to ‘keep’. Click the Remove Background button to the right of the Selection button. The background around your selection will be removed.

You can now save the file or copy and paste the image somewhere else and the background will be transparent.

How to remove background from a signature in PowerPoint 

Like Word, PowerPoint has some basic photo editing capabilities that make it easy to remove signature backgrounds within the application. This allows you to make edits and place your signature within the same application, without having to use a third-party tool.

PowerPoint, like Word, also gives you the ability to save the edited photo locally for use in future documents. Here’s how. 

Note: This works best for signatures that have a uniform background. Because our example doesn’t have one, we’ll demonstrate this example starting with a blue background. 

Create a new presentation in PowerPoint. Click Insert in the top ribbon > Picture > This Device. Select your image file and click Open.

Select your image and ensure you’re in the Picture Format tab in the top ribbon. 

Click Color on the right side of the screen > Set Transparent Color. Click on the background portion of your signature image. 

PowerPoint will automatically remove all parts of the image that are the color of the area that you clicked on, making the background transparent.

You can then adjust the size of the signature using the Transform tool in PowerPoint and either use it within your existing presentation or or save it locally as an image file. 

To save locally, right click on your image > Save as Picture >  select PNG as your file type to retain your transparent background, select a file location and click Save.

Canva is another online graphic design and photo editing tool, similar to PhotoRoom. It comes with a range of photo editing features that allow you to manipulate images on your phone or desktop.

GIMP (short for GNU Image Manipulation Program) is a free, open-source image editing tool that offers a similar suite of tools as Photoshop, but without the hefty price tag. GIMP is only available on desktop. 

Here’s how to remove a signature background using GIMP.  

If you don’t have GIMP installed, download it from gimp.org. Launch GIMP and open your signature file by clicking File > Open.

To make the background transparent, go to Layer > Transparency > Add Alpha Channel. This step ensures any deleted areas of the image become transparent.

Use the Fuzzy Select Tool (magic wand icon in the toolbar) to click on the background of your signature. Adjust the Threshold in the tool options if needed to capture more or less of the background.

Once the background is selected, press Delete on your keyboard to remove it.

If there are areas that weren’t selected properly, use the Eraser Tool to manually remove those parts.

Go to File > Export As. In the dialog box, select PNG from the file format dropdown to keep the transparent background, then click Export and confirm the settings.
