Tool 2: How to sign an image with Photoshop
Adobe Photoshop is one of the most popular premium photo editing programs available. It allows you to create, edit, and alter images, and with this application, you can sign an image.
The steps involved in signing an image with Photoshop are complex; it involves two processes. First, you have to create a brush preset based on a scanned image of your handwritten signature. Then, you’ll add it to the image you want to sign.
Here are the steps required to sign an image with Photoshop::
Being by writing your signature on a plain white piece of paper. Use a fine point permanent marker; black works best. Then scan or take a high-quality image of the hand-drawn signature. You’ll be using it as a digital signature, so save it as a JPEG on your computer.
Once it’s saved to your computer as a digital image, open it in Photoshop. Crop as much of the white background as you can. Then you’ll need to use the magic wand tool to select the written signature. After doing so, hit Edit > Define Brush Preset, and give it a name.
What you’ve done is created a new brush that allows you to stamp your signature on images with one click. You’ll be able to use this for any images and documents you need to sign in the future.
The next step is to simply open the image that you want to sign in Photoshop. Then, simply use the new brush to add your signature to the image. Alter and adjust the size of the brush to fit the signature to the image appropriately.
- High image quality
- Easy to repeat once you’ve done it once
- Can’t create a digital signature with the program
- Getting access to Photoshop is expensive
- Adding a signature to an image is overly complicated
- Steep learning curve
Tool 3: How to sign an image with GIMP
GIMP is a free, open-source photo editing software that can help you add signatures to images. It’s considered the closest thing to a free version of Photoshop.
Like Photoshop, signing an image with GIMP is a little complicated; it requires you to scan a real hand-drawn signature. The step-by-step details are outlined below:
Draw your signature with a fine point black Sharpie on a piece of white paper. Either scan or snap a photo of this hand-drawn signature; ensure it’s a high-quality image. Save it as a JPEG file.
The next step is to open the image in GIMP, followed by selecting Colors > Threshold. You’ll then be able to adjust a slider. Make the signature as black as possible and the background all white. You’re essentially tweaking the contrast and brightness here.
After doing that, right-click the image, and select “Add Alpha Channel.” This will add a transparent background layer.
Then, use the Select by Color tool to delete the white background in the original layer. Get rid of any remaining white background with the Eraser tool. You’ll now be left with your black signature and a transparent background. Save your newly created digital signature.
The final step is to open the image you want to sign and simply add and overlay your digital signature. Tweak its size to fit the document.
- Higher image quality
- Easily repeatable process
- GIMP is a free program
- Time consuming
- There’s no feature to add a simple signature
- Questionable signature quality
- Takes a while to get the hang of it
Tool 4: How to sign an image with Paint
Microsoft Paint is the default image editor that comes on every Windows computer. It’s a simple program that allows you to alter images. You can change their color and size, among other things. Compared to GIMP and Photoshop, it’s a little underpowered.
Like with GIMP and Photoshop, to sign an image, you’ll first need to create a digital signature. Follow these steps to do so:
Get a piece of plain white paper, and write a nice signature with a fine point black Sharpie. Get a high-quality digital image of this by either scanning or taking an image of it. Save it as a JPEG file.
Once that’s done, open the image in Paint. Crop out the excessive white background, then use the selection tool to “select all” and copy it.
Then, open the image you want to sign in a new Paint window. Paste your digital signature into the image, and while it’s still selected, change the selection tool settings to “Transparent selection.” Finish off by resizing and placing the digital signature so it fits appropriately.
- Microsoft Paint is a free program
- Relatively easy to do again after you’ve done it once
- The signature can be low quality
- Unnecessarily long process
Tool 5: How to sign an image with Illustrator
Adobe Illustrator is a vector graphics editor that helps you create and alter vector images. These are unique images that remain smooth, not pixelated, when zoomed in. It’s an ideal photo editing program to sign an image with and a companion app to Adobe Photoshop.
Using Adobe Illustrator to sign an image is, like with Photoshop, somewhat technical. You’ll first need to create a vector image of your digital signature before you sign your image. These are the steps you have to take:
Write your signature with a fine point Sharpie on a plain white piece of paper. Then, take a photo or scan it. Ensure you get a high-quality digital image — JPEG preferably.
The next step is to open the image in Adobe Illustrator. Crop the excessive white background so only the signature and a small bit of the border remain.
Then, select Object > Live Trace > Make. Use the pen tool set to .25 stroke to trace your signature carefully. Once done, change the stroke to mimic the weight of the drawn signature. Then save the newly created digital signature as a vector image.
The final step is to open the image you want to sign and overlay your digital signature vector image. Adjust its size and placement to fit the document.
- Amazing vector image quality
- Easy to repeat once
- Technical, complex process
- Initially takes a long time to complete
- Adobe Illustrator is an expensive photo editing program
