There are many reasons why you might want to combine photos. Maybe you'd like to merge two photos of your pets, children, or family members. Or, if you're a business, you might want to put two pictures together of your office locations or related products.

You don't have to be an expert at photo editing to turn two pictures into one. With these easy-to-use online tools, you can combine photos vertically or horizontally, with or without a border, and all for free.

1. PineTools

PineTools merge picture feature

PineTools lets you quickly and easily merge two photos into a single picture. If you want a fast tool that enables you to add a border and is super simple to use, this is it. Combining two photos in one frame online using PineTools is pretty simple.

First, upload each image to get started and use the available zoom or move tools for each if you like. Then choose to position the photos next to each other, either vertically or horizontally. You can adjust the sizes of the images next. This lets you magnify the smaller one, reduce or crop the largest, or constrain the proportions if you prefer.

Then you can add a border to the combined image. Use the slider to select the thickness and choose the color. PineTools gives you the option to select an exact color using the Hex code or RGB values for color geeks.

When you finish, click Merge. Your combined photo will pop into the Output Image section of the page. From there, you can download the image as a PNG, JPG, or WEBP file. And PineTools is not just a service for merging two photos online, it has plenty of other tools that you can find handy in different situations.

2. IMGonline

IMGonline is another good site that lets you combine two images into one with different settings to make your finished photo perfect.

Start by uploading each photo and selecting the position from vertical or horizontal. Then move on to the helpful settings. You can set an automatic adjustment for the sizes so that the images adapt to each other. For instance, you can have the larger of the two adapt to the smaller one. You can keep your images sized the way they are as well.

IMGonline also lets you rotate the photos if needed, trim them using values for each edge, and apply a mirror reflection for something different.

Select the file format you'd like to use from JPEG or PNG-24 and mark if you'd like to copy the metadata from the first photo. Then click OK, and you'll be able to download your merged photo. Image processing typically takes about 30 seconds maximum. Once done, select Open processed image or Download processed image to save your image directly.

Besides the ability to merge images online, it also provides other image editing tools as well. For instance, it has a photo collage maker feature that allows you to join more than two photos. However, you won't get the same amount of editing tools here like on PineTools.

3. OnlineConvertFree

It doesn't get much easier to merge two photos than OnlineConvertFree. Similar to the other tools mentioned so far, this site gives you the basic option to combine two images.

You simply upload each photo, choose the position from vertical or horizontal, select the size adjustment, and pick the thickness of the border. Finally, click the Save and Download Image button to download your combined image. It's that easy! The limitation of this simplicity is you don't have access to a variety of options when combining images like different image formats (images are saved as PNG by default).

As you may have guessed by the name, OnlineConvertFree offers additional features such as file conversions along with more image tools like a resizer, rotator, and cropper for cropping images online. So be sure to check that out as well.
