Our photo cropper supports JPG, PNG, GIF, BMP image formats. Please note, that if you don’t have enough free memory space on your computer or phone, you won’t be able to download your cropped copies, since they can be of any size.

If you want to upload photos from a cloud service, you must enter your login details. Do not worry; we do not store your data on the server and do not allow third-parties to access it!

Did you accidentally upload an extra picture? Delete it – on the left, hover over the small version of the image, and click on the trash can icon.

Do you need to add another picture? Select "Add images".

Have you uploaded images that you don't need to work with right now? Delete them all at the same time using the “Clear images” button.

How do you crop images manually?

We don’t limit what Watermarkly users can do. Each of you has the ability to crop image however you want. Suppose you know that you need an image with an aspect ratio of 3:5. There's no need for you to keep moving the blue borders with your cursor until you get the ratio approximately right. Just write “3:5” into the menu bar. After that, move the created rectangle to the place where you want to crop photo.

The app comes with the following predefined aspect rations. You can add and save your own crop aspect ratios.

  • General proportions: 1:1, 1:3, 2:3, 2:1, 3:2, 3:4, 3:5, 4:3, 4:5, 5:3, 9:16, 9:20, 10:16, 16:10, 16:9, 20:9
  • Instagram: story, square, portrait and landscape posts
  • Facebook: post, profile cover, page cover, event cover
  • YouTube thumbnail and channel
  • LinkedIn profile and post

Another way to set your parameters is to write the resolution in pixels. For example, like this "1200x800". Suppose you know precisely what size of the picture you need, do not waste time, and type them into the menu bar. This will significantly simplify and speed up your work with images.

How to crop picture into a circle/square

To crop picture into a circle/square, proceed as follows:

  • Select a shape (click on the square or circle to the left of the extended menu).
  • Move the shape to the part of the picture where you want to crop the photo.
  • Edit the cropping area. The blue borders are not locked to change their position. You can make a rectangular shape out of a square / an oval out of a circle. All elements that are outside the blue borders will be automatically deleted.

Previously used crop settings

If you tend to crop your photos in a similar way or use customized presets, the list of previously used image crop settings will surely simplify and speed up your workflow. You can access it in the Options drop-down menu.

Moreover, the very last crop settings you used in Watermarkly’s image cropper will always show up automatically the next time you open the app and upload some photos.

Fixed aspect ratios

These options include locked aspect ratios of your cropping area.

In this case, the absolute size in pixels is irrelevant. Instead, you select the ratio of your cropping area’s width to its height. Our online image cropper offers these options: 1:1, 3:2, 4:3, 16:9, 2:3, 3:4, 9:16, 10:16. If you need a ratio that is not on the list, click into the selection box and type in, for example, 4:5.

You can make the cropping area bigger or smaller, or move it to any other location within the image. But the selected aspect ratio will be locked: if you make the cropping area wider, its height will increase automatically as well.

If you have a batch of photos, you can set one ratio option for all images or select different ratios for each photo separately.

Social media dimensions

With our photo cropper you can crop images for the most popular dimensions for social media platforms such as Instagram, Facebook, Twitter, Youtube, LinkedIn.

Unlike standard aspect ratios, these options affect not only the ratio of width to height but also the size in pixels. The resolution of your cropped copies will be changed automatically according to the option of your choice. For example, if you select "Instagram Story 1080 × 1920", your cropped picture will be 1080 pixels wide and 1920 pixels high.

You can also manually change the size of your cropping area by entering your preferred width and height in pixels into the selection box. For example, you can enter 1200 × 1900.

Straightening a horizon

With our Photo Cropper, you can not only crop your photos but also rotate your whole image to any angle. This feature can be especially useful if you need to fix a crooked horizon.

To the right from the Options drop-down menu, you will see an arrow that allows you to rotate your image. It is initially set to 0°, but you can set any angle from -7 ° to 7 °. Depending on which side you want to tilt your photo to, move the blue circle to the left or right.

Step 3. Preview your cropped images.

Click on the "Crop images" button and then select “Preview.” Check how our app changed each picture (if you worked with several at once).

If you are happy with the results, go back to the output settings. Click on the cross in the upper right corner for further work.

Step 4. Select file format.

Our photo cropper offers several formats in which you can save your images. We also give a short description in brackets next to each format so that you can easily understand what you will get in the result.

For example, if you need a large file size without quality loss, you’ll have to select PNG. If you want to get a file of a small size, choose to convert it to JPEG with additional compression.

Crop a Picture Using the Rule of Thirds

If you’re cropping a picture for the first time, there are a couple of things that you need to take into account. Naturally, no one is stopping you from cropping images however you want. That said, it’s better to learn the rules before breaking them. Cropping an image is something you need to put some thought into; if you want to achieve a specific result, that is.

With the help of cropping, you can make the composition more balanced…or, on the contrary, throw it out of balance; if that’s your goal. The one rule that you surely need to learn is the Rule of Thirds.

This rule is insanely popular for a reason. The rule of thirds is one of the fundamental compositional rules in art, photography, cinematography, animation – pretty much all types of visual art, really. This rule is powerful, yet quite simple.

You need to divide an image into nine equal parts, forming a grid with two horizontal and two vertical lines, which create four intersection points. Now that you have this grid, you need to place your subject and some other key elements along the grid lines or at the intersections.

crop image

It’s also possible to position your subject in the center, but this type of composition works best if you have some symmetry in your shot. If you place the key elements at the grid lines or intersections, you will get a balanced and visually pleasing composition.

For example, if you have a horizontally oriented landscape, you can place the horizon on the bottom horizontal line. And, if possible, position other key elements – trees or mountains, for instance – at the intersections or near them.

If you have a portrait and your subject is a person, it’s a good idea to place the person’s eyes on the top vertical line or, what can be even better, put one of the eyes at one of the intersections. That will draw all the attention right to the eyes.

The rule of thirds is so popular that you can enable its gridlines in the majority of digital cameras and camera apps on a smartphone. It can be found in a lot of image editors, too; including Watermarkly.

This is due to the fact that by following the rule of thirds, you’ll get a well-balanced composition where the viewers’ attention is guided right to the key elements.

However, it’s worth mentioning that like any other compositional rule, The Rule of Thirds is merely a guideline, not a set-in-stone law that you need to abide by. You don’t have to follow it every single time. In fact, sometimes, by breaking it, you can create a masterpiece. Following the rules is good, but what’s more important is trying things out. So, get creative and experiment!

How to Crop Images Properly

Cropping a picture can fix compositional mistakes and make your image much more visually pleasing and impactful. It’s a tool that everyone who deals with visual content needs to master. And it’s not that difficult to do. Here are some things that you need to keep in mind if you want to crop a picture properly:

crop picture
  • Remove unnecessary elements. If there are any redundant or obtrusive elements that distract from the main subject and don’t add anything special to your image, get rid of them with the help of an online image cropping tool.
  • Focus on the main subject. Any image should have a main subject. Make sure that all the attention is focused on it. If possible, you can crop in closer to your subject to make sure that nothing is distracting from it.
  • Don’t forget about the aspect ratio. If you want to remove just tiny bits of your image, make sure that its original aspect ratio is locked. But you can also change it or even experiment with different aspect ratios, if necessary.
  • Keep an eye on the composition. If your original image has a decent composition, make sure that you’re not messing it up while cropping.
  • Straighten the image. If the horizon or any other object in your frame looks weird, because it’s tilted, it’s better to straighten it by tilting the image itself.
  • Remember to experiment. Image editing can be a creative process, too. Even slight adjustments and alterations can have a dramatic effect on an image. So, try cropping a single image in different ways and see which option you like the best.

When exporting, don’t forget to select the correct file format. For instance, JPEG is great for the web, while TIFF is perfect for printing.
