The Google Slides steps
Google’s help page calls this masking an image. It describes clicking the down arrow next to Crop and choosing the shape you want, then dragging the colored handles to adjust it.
- Insert the image on your slide.
- Crop it to a square with the regular crop, or insert a square image to begin with.
- Select the image.
- Click the down arrow next to the Crop button.
- Click the round shape in the list.
- Drag the colored handles to adjust the picture inside the mask, then click away.
Why the circle becomes an oval
The mask takes the shape of the picture box. If the image is wider than it is tall, the round mask stretches to match and you get an oval. Square images are the simple fix: their box is equal on all sides, so the mask stays a true circle.
If you already masked a wide image, undo it, square the picture first, and apply the mask again. Trying to fix the oval with handles afterward rarely looks right.
Make the circle before you open Slides
You can also skip the mask entirely. Use the editor at the top of this page to crop the photo into a circle, download it as a PNG, and insert it on the slide. The outside of the circle is see-through, so the slide color shows around it, whatever theme you use.
This is handy for a template you share with others, because the round photo stays round even if someone changes the theme.
Logos on title slides
A logo on a title slide usually needs to stay whole. A round mask can cut off letters near the edges. Use the Fit option in the editor on this page to shrink the whole logo inside the circle, then insert the result. A face, on the other hand, usually looks better filling the circle.
What about Google Docs?
The same Google help page explains that Docs offers a rectangular crop: click the image, click Crop, and drag the handles. The mask-to-shape steps are written for Slides. To get a round photo in a document, insert a circle PNG made on this page.
On a phone or a tablet
Google’s steps are written for a computer. In the phone app, the image tools may sit in a formatting panel rather than a toolbar. If you cannot find the mask, make the circle in your phone’s browser on this page and insert the saved image.
Before you present
Open the deck on the screen you will use. A theme that looks dark on your laptop can look pale on a TV, and a soft edge around a photo may suddenly show. Check that every circle is round and every face is centered, and fix any outlier before the meeting starts.
Choosing photos for a team or class slide
When several people appear on one slide, consistency matters more than perfection. Ask for photos taken from the chest up, facing the camera, with a plain background. Mixed photos, such as one close-up, one full-body shot, and one group picture, are hard to make match, even with careful masking.
Crop the outliers first. Zoom in on the distant ones and leave the close-ups as they are, so every face ends up a similar size inside its circle.
Keeping every circle the same size
Masked images can drift in size as people edit a deck. Pick one size for headshots, apply it to the first picture, and match the others to it. Lining the circles up along the same row and spacing them evenly makes the slide look designed rather than assembled.
If you build a template for others, place one finished round photo on the layout as a guide. People are more likely to follow an example than a written rule.
Dark themes and transparent corners
Masks in Slides hide the outside of the shape, so they work well on any theme. Round PNGs from this page do the same, because their corners are clear. Either way, check dark photos on dark themes. A thin light ring, added with the border tool, helps a dark-haired portrait stand out.
Describe each photo for screen readers
Google Slides lets you add alt text to images. Give each round headshot a short description, such as the person’s name and role, so classmates or colleagues using a screen reader know who is pictured. It takes a few seconds per photo and also helps when the deck is shared as a document later.
Turning a group photo into individual circles
Sometimes the only picture of a team is one group shot. Instead of masking the whole photo, crop each person separately in the editor on this page, zooming in until the face fills the circle, and download one file per person. Insert those circles on the slide in a row. The faces will be much easier to recognize than in one wide picture.
If the group photo is small or blurry, the individual circles will be too. In that case, ask for new photos if the slide is important.
Speaker and webinar slides
A speaker slide usually shows one round headshot beside a name and a short bio. Make that circle a little larger than the ones on a team slide, so the audience can see the speaker’s face clearly while they are introduced. A warm, smiling photo works better than a stiff formal one.
Use the same style for every speaker in an event deck, and the whole presentation will feel polished. That is the real goal of every round photo on a slide.
Frequently asked questions
Where is the circle option in Google Slides?
Select the image, click the down arrow next to Crop, and click the round shape.
Why did I get an oval?
The image was not square, so the mask stretched to match it.
Can I crop picture into circle in Google Slides on my phone?
The phone app may hide the mask. Make the circle on this page and insert the image instead.
Does this work in Google Docs?
Docs offers a rectangular crop. For a round photo, insert a circle PNG.
How do I keep the circle round when resizing?
Drag a corner handle, never a side handle.
Is my picture uploaded to this site?
No. The editor here runs in your browser.
