I have tried many methods and tools online, and so far PhotoScape is my favorite for resizing photos and adding watermarks in bulk. It saves a lot of time and effort, and it’s completely free. I now use this method for Lucid Gen, and it has made editing photos and creating Shopee photo frames in bulk much less painful. So what are you waiting for? This guide is for computers. If you use a phone, check out the article How to add logo to photo on the phone.
Install PhotoScape
PhotoScape has been around for a long time. To keep up with the times, there is now PhotoScape X for Windows 8 and later and macOS. I leave the links here for reference only. You don’t need to download from them, just get it from the Store as shown below.
- New version: x.photoscape.org
- Old version: photoscape.org/ps/main/download.php
Install PhotoScape for Windows
On Windows, open the Microsoft Store app, search for PhotoScape X, then click Get and install it.

Install PhotoScape for macOS
On macOS (MacBook), open the App Store, search for PhotoScape X, then click Get. Sign in to your Apple account if the App Store asks you to.

How to resize photos and add watermarks in bulk
Open PhotoScape X. The interface is the same on Windows and macOS. First, navigate to the folder containing the photos you want to resize and watermark. Then switch to the Batch tab on the menu bar.

Select all the images in that folder and drag them onto the batch bar at the top, as shown below.

How to batch resize photos
To resize images in bulk, open the Resize section, then choose how you want to resize them.
- Original Size: keeps the original image size.
- Width (px): resizes the image to the width you set, and the height scales automatically.
- Height (px): resizes the image to the height you set, and the width scales automatically.
- Ratio (%): resizes the image by a percentage of the original.
- Long Edge (px) and Short Edge (px): work in a similar way, picking from standard sizes.
- The last option: resizes to a custom size you set.

How to add a watermark to photos in bulk
To add a watermark, open the Insert section, click the plus button ( + ), and select Image. Then find your logo file and add it.

Click the logo to open the customization window. Choose an anchor position so the logo automatically aligns to that corner. Then adjust the X and Y values, or drag it with your mouse to the spot you like.

You can also drag the round handles on the logo to resize it. If your logo already looks good, you’re done. If you want to add some effects, try the options in the editing panel. A drop shadow can look nice too.
Once you’re happy with the logo, skip to the step of saving the images.
How to add a logo with text to a photo
If you don’t have a logo, or you have one but don’t want to use it on your photos, you can use text like I do. (A little secret: I don’t use an image logo because it may change in the future, while text stays the same, hehe.)
Click the plus sign ( + ) in the Insert section and select Text to add a text logo to the image.

Type the text you want, then set its anchor position as well. With text, you get even more effect options. Customize the color and font in the bar circled in red in the picture.
Add a few effects, and it will look great. Take a look at the More Options section:
- Transform: curves the text.
- Outline: adds a border around the text.
- Drop Shadow: adds a soft shadow under the text.
- Outer Glow: makes the text glow.
- Gradient: blends colors across the text.

You can also add a decorative element so it looks less plain. Click the plus sign ( + ) and select Figure.

Select the element you want to add. For example, I want a frame around the text, so I choose the square border.

Adjust it a little so the text and the border are balanced.

Once you’re done with the text logo, let’s move on to saving the images.
Save the resized and watermarked images in bulk
OK, now that the logo is done, click through the other photos at the top to check that it looks good on all of them.

Click the Save button in the lower-left corner, then use the same settings as me for the best result, or choose your own if needed.
- Image Format: choose PNG for high quality.
- JPEG Quality: set it to 100 if you choose JPG or JPEG.
- Save Location: choose Custom, click the 3-dot button, and pick the folder you want to save to.
- File Naming: choose Save as the same name to keep the original file names.

Saving is very fast. In the blink of an eye, 2 or 3 photos are done.

Now open the output folder and check the results. All the images have been resized and watermarked in one go.

Conclusion
I have to say, using PhotoScape X to resize and watermark photos in bulk is really satisfying. You only need to set it up the first time. Next time you open it, your previous Batch settings are still there, so just drag the images in and click Save. It’s fast and free, while many online tools ask you to pay for an upgrade and are quite slow. If you find this method useful, leave a comment below.




Another great tool for mac os is Mass Watermark. It has a quick and easy to use UI and allows batch watermarking with QR Codes too.
Yes, thank you!
