9 Best Smiling Filter Apps and Tools to Brighten Up Your Photos

On social media today, a smile can completely change how your photo looks. It shows your friendliness and instantly catches attention. But sometimes your smile doesn't turn out right in a shot.

That's where smile filter apps step in. These tools use photo editing or AI to fix or add smiles after your photo is taken, so your photos always stay on point.

Part 1. 9 Smiling Filter Tools You Can Use Online, on Mobile, or Desktop

No matter if it's a family photo, a solo selfie, or a random group snap, a tool with a smiling filter lets you upgrade your pictures in just seconds. Below, you'll explore some of the top smile filter apps that take your photos to another level.

1. SmilingFaceMaker

SmileFaceMaker is one of those tools that surprises you with how simple yet powerful it is. It's completely free to use and gives you natural results that look real, not over-edited. What makes it different is how it handles complex edits, such as opening closed eyes and adding a genuine smile at the same time. If you want to brighten up your photo in a natural way, this tool does the job perfectly.

You can use it directly from your browser, so there's no need to download or install anything. It's especially great for anyone who just wants to upload a photo and get quick results, and you don't have to learn any tricky settings.

One of its strongest features is the variety of templates available. For example, you can pick options like "Closed Eyes to Genuine Smile" or "Closed Mouth to Brilliant Grin." Each of these offers several variations so you can choose exactly the type of smile you want. It also offers Eye-Opening Technology that turns photos with closed eyes into ones with open, smiling expressions.

The tool uses advanced AI to create high-quality, realistic smiles that smoothly add to your original photo. The interface is clear and beginner-friendly, and it values privacy too. It doesn't store your images and uses encrypted connections for safety.

SmilingFaceMaker is only for smile generation, so there are no unnecessary features to go through, and the best part is that you'll get your photos watermark-free. The downside? It is only available online and may take a bit of time for results during busy times.

2. YouCam Enhance

YouCam Enhance is great if you want more control over how the smile appears in your photo. It's not just about applying a smiling filter; it lets you guide the process using text prompts, which gives you creative freedom to shape the expression you want. The process takes a bit more time compared to simple smile apps, but the results are worth it once you get the hang of it.

Its main feature is AI Replace, which lets you modify facial expressions using words. You just brush over the mouth area, type "smile," and the app applies a natural-looking smile filter that goes well with your face. You can also try other words such as "grin," "happy," or "smirk" to test out different results. This feature works on iOS, Android, and desktop, so you can use it wherever you prefer.

The app uses advanced AI to maintain your original facial details while adding realistic smiles. It doesn't label it as a "Smile Filter," but the AI Replace function does the same job effectively. You can start with five free credits, and if you like the results, extra credits are available through a monthly plan.

YouCam Enhance can customize your smile however you want, and it doesn't leave any watermark on the image. The catch is that it can be confusing at first because there's no direct "smile filter" button, and it takes a few extra steps to finish an edit. Also, once your five free credits are used up, you'll need a subscription to continue generating photos.

3. RetouchMe "Make a Smile" Designer Filter

RetouchMe is for you if you prefer real people editing your photos instead of automated filters. It connects you with professional designers who manually adjust your image. By choosing the "Make a Smile" option inside the app, you can have an editor add a natural smile that suits your face shape and lighting. The results come from actual human work, not presets, so every edit looks personal.

What stands out is that RetouchMe isn't just limited to smile edits. It offers more than 200 other services, from skin fixes to full facial retouching. You can also give short notes explaining how you want your smile to look, and the team follows them while editing. The app is available for both iOS and Android, and you'll need credits to use the service, starting at $0.99 per edit.

One thing, though. There's no direct chat or feedback system, so you can't explain details beyond the initial request. You also need to wait about 15 minutes for each edit, and it's a paid feature with no free preview. Since it's a mobile-only app, you'll have to use it on iOS or Android.

5. Fotor AI Smile Filter

Fotor AI Smile Filter is for anyone who wants a quick way to add smiles to photos online. It's a web-based editor that uses AI to detect faces and modify expressions automatically. Along with smile generation, you also get other features like lip color adjustment and skin smoothing, which help refine portraits in one place.

The actual process can feel a bit unclear. While the page mentions a free smile filter, the option isn't directly visible in the menu. Instead, you need to use the AI Replace feature, where you upload your image, brush over the mouth area, and type a text prompt such as "smile" or "happy." The AI then processes your image and generates the new expression.

The results are realistic enough for casual use, but there's limited flexibility in how the smile turns out. Even if you use different prompts, the output often looks similar. You can try the tool twice for free, but after that, it requires a Fotor Pro plan that starts at $8.99 per month. Free previews are also of lower quality, and downloading the final version requires signing up for a 7-day trial.

The great bit about Fotor is how fast it runs and how neatly it combines smile editing with beauty tools. However, it's not ideal for you if you want total control or watermark-free results. The free version limits what you can do, and with the trial, the downloaded images carry watermarks unless you subscribe.

6. Adobe Photoshop Express Mobile App

Adobe Photoshop Express is a handy option if you're already familiar with Adobe tools and want a quick way to adjust facial expressions. It has an "Add Smile" filter that uses Adobe's Sensei AI to slightly lift the corners of the mouth for a softer, natural effect. The change isn't dramatic, but it's just enough to give your portrait a friendlier look.

Also, you get detailed controls. You can use a slider to fine-tune how strong the smile appears and even adjust lip positions if needed. Alongside that, Photoshop Express also includes its usual set of photo tools like filters, cropping, and tone adjustments, giving you an all-in-one space for quick edits. It connects smoothly with other Adobe products, too, so if you already use Lightroom or Photoshop, your files get synced.

The main plus here is how easy it is to use. The Add Smile feature is free, and the interface is super easy for quick edits. However, it only provides one type of smile, and the change is often quite subtle. You'll also need the mobile app, since this feature isn't available on desktop or web.

7. FaceApp Smiles Filter

FaceApp is one of the most recognizable tools for changing facial expressions, and its Smiles filter keeps things playful while offering different looks. It uses AI to reshape facial features, letting you pick from smile types like Classic, Wide, Tight, and Closed. You can also try other effects, like hairstyle or hair color changes, or edit the background as well.

The results are quick, but the smile styles aren't as different as they sound. In practice, the app only gives you two real variations. One with an open mouth and one with a closed one. Still, it's reliable for fast edits that you can easily post online, especially if you already enjoy experimenting with FaceApp's filters.

The main upside of FaceApp is its speed and simplicity; the Smiles filter applies instantly, and the interface stays clean. The downside is that it requires a PRO subscription that costs $8 a month, and there's no free trial to test it beforehand. Also, since it only works as a mobile app, you'll need to use it on iOS or Android.

8. Facetune

Facetune comes with precise tools for adjusting your smile, reshaping facial features, skin correction, and makeup effects. The Smile Tool, which acts as a smiling filter, lets you change the size, width, and height of your smile using a simple slider and gives you just enough room to tweak your expression while keeping it natural.

It's an excellent choice for people who enjoy experimenting with multiple edits in one place, especially since it's available on both iOS and Android.

The main advantage of Facetune is the amount of control it gives you, and it also provides you with a free trial before you decide to subscribe. The limitation, though, is that the smile adjustment is subtle. It slightly lifts your expression rather than creating a full grin. You also need the mobile app to use it, as there's no web version.

9. Evoto AI

Evoto AI is a professional photo editor and uses advanced tools powered by AI to refine facial details, which also has a smiling filter. The Smile Enhancement Filter Tool gives you two main options. Gentle Smile and Smile Generation. Both are designed to adjust the curve of the lips for a perfect smile.

You can also modify lip shape and fullness through Lip Adjustment and smooth the skin around the mouth. The editor runs on Windows and Mac; it's free to download, and you can test its features before unlocking the paid options.

Evoto AI stands out for its precision and quality. The ability to fine-tune every detail makes it perfect for retouching portraits where small adjustments matter. However, it's not for casual users as it can be a bit difficult if you're new to editing. The smile filter tools also lean toward subtle effects, so don't expect big expressions or dramatic changes. Still, for photographers looking for control and realism, Evoto delivers strong results.
