The gender swap craze on TikTok earlier this year was impossible to miss. It felt like everyone was flipping their look to the opposite gender. But as those viral videos spread to Snapchat, Instagram, and beyond, a lot of people wanted to join the fun without downloading yet another app like TikTok. So many online gender swap filters have started trending, meaning you can use them instantly in your browser and share them anywhere you want.
I decided to test a few of the most popular ones, including some free options, to see which actually deliver the best results.
Why Gender Swap Filters Keep Going Viral
The gender-swap filter keeps trending not just because it’s funny, but because the best versions now run entirely in your browser. That means no downloads, no sign-ups, and outputs you can post anywhere in seconds.
Why creators love browser-based filters
- Zero install. Open a link and try it, which is perfect for quick trends and collabs.
- Instant reuse. Export a JPG/MP4 and drop it straight into TikTok, Instagram, Snapchat, YouTube Shorts, or your editor.
- Less data shared. Many web tools work without accounts, reducing exposure of personal info and face data.
Top 5 Filters for Gender Switch You Should Try
Clipfly
Clipfly’s free AI gender swap tool lets you easily and naturally swap your gender in a video—no download required. Here is a step-by-step guide about how to use Clipfly to switch gender:
Step 1: Upload Your Image
Upload a photo you want to gender-swap. It works best with solo portraits, but group photos are supported too.
Step 2: Swap Your Gender
Clipfly’s AI analyzes facial features and details in your photo to quickly generate a fun video.
Step 3: Download Your Result
Once you’re satisfied with the AI-generated result, download it in high quality without watermarks.
Pros
Fast & Realistic: Generate your video quickly with natural, realistic results.
No Watermark: Keep your creations clean and distraction-free.
Cons
Free account is granted 15 credits and each switch costs 10—you instantly run out of credits!
Media.io
Media.io smoothly changes your gender from male to female or vice versa with an AI gender swap filter. The experience is browser-based and works in just a few clicks. Though the free version applies watermarks and caps resolution. Still, it’s a quick option if you just want to test the trend.
How to use Media.io’s online gender swap filter
Step 1: Upload Your Photo
Open Media.io’s gender swap filter and upload the image you want to transform. Most common formats are supported.
Step 2: Choose Target Gender
Select your target gender and click Generate to begin the AI transformation.
Step 3: Preview & Download
Review the result, optionally try other filters, and then download your new photo.
Pros
Instant to Use: Runs online with smooth cross-platform compatibility on Android, iPhone, Windows, and macOS.
Data Privacy Assurance: Uploaded files are automatically deleted after several hours.
Cons
Upload speed can be slow.
Registration barrier at generate/export. The flow appears no-login at first, but the Generate step typically requires creating an account.
Credit mismatch: free account gives 5 credits, but one gender-swap video costs 6, so you can’t try a full conversion of video for free (but image conversion only costs 1).
UUININ
UUININ is more than just a face swap tool but more like a short-video ecosystem built for creators. The gender swap filter is part of its creative toolkit, but what sets it apart is how seamlessly it integrates with TikTok-style content.
How to use UUININ’s AI gender swap filter
Step 1: Upload Your Photo or Short Clip
Open the gender swap page and upload a selfie or a short video. Solo portraits work best, group shots are supported as well.
Step 2: Choose Target Gender & Generate
Select Male or Female and start the swap. The AI analyzes facial features to produce a natural, creator-ready result.
Step 3: Download & Share Anywhere
Preview and download your swap as JPG/MP4.
Optional Step: Publish inside the UUININ community for exposure, live streaming, or affiliate promos (account required for community features).
Pros
Best swap accuracy, fast processing, no watermark, built-in social platform with growth and monetization opportunities.
Cons
Smaller knowledge base compared to older apps.
AiDesign
AiDesign works more like a prompt-driven AI photo editor than a fixed filter. Just upload your image and describe the change you want (e.g., “swap gender to female with natural makeup”), and the model generates the result.
How to use AiDesign’s prompt-based gender swap
Step 1: Upload Your Image
Choose a selfie or portrait (solo faces work best). Full-body photos are accepted but may crop tighter during generation.
Step 2: Enter Your Prompt & Generate
Describe the target look, e.g., “Turn me into a man.” Click Generate to process.
Step 3: Review & Download
Check the preview. If needed, refine the prompt (add lighting, hair length, style cues) and re-generate. When satisfied, download the image (wow! no registration window prompted at all!).
Pros
Simple UI: type a prompt, get results—including gender swap.
No login in my test; 4 free credits observed.
Cons
Face detection failed once on the free tier (output showed only half a head).
Full-body input returned a half-body result (possible auto-crop; unclear if this is a free-tier limitation or model behavior).
Bylo.ai
Bylo AI offers a browser-based interface to run multiple image models (e.g., Nano Banana/Gemini 2.5 Flash Image, GPT-4o Image, Flux) from one place. You can apply gender swap as an image-to-image transformation and also use text-to-image, with basic editing and refinement tools available—reducing the need to switch between separate services.
Use Bylo.ai’s online AI gender swap tool step by step
Step 1: Upload Your Photo
Open the gender-swap feature, upload a portrait (solo faces work best) or start from a text prompt. Full-body shots are supported but may crop tighter during generation.
Step 2: Add Other Ideas (Optional)
Add guidance with a short prompt (e.g., Turn me into a man.”).
Step 3: Generate, Review & Download PNG.
Click Generate. Review the preview and then download the result (JPG supported).
Pros
Free Plan has enough support for testing: 5 credits/day, 20+ advanced AI editing tools and 40+ art effects/filters for fine-tuning, High-quality PNG downloads, 7-day storage, and email support.
Cons
Slow/erratic generation at times (stuck at “0% Generating,” then finishes later).
Licensing limits: Free users may use images for personal purposes only, and only subscribers get commercial usage (marketing/branding/content).
Proportion issues: some gender-swap results looked unaligned (e.g., large head / small body).
How Do Gender Swap Filters Compare Across Apps?
By running the same files through each tool and scoring against these criteria, I built a practical, creator-centric view of how gender-swap filters perform when friction-free, post-anywhere results are wanted.
And here is what I thought was important for a nice online filter.
| App | If Download Required (Browser-only?) | If Login Needed (Usable result w/o account?) | Privacy Signals (Prompts, Data, Profiles) | Notes |
| Clipfly | No — runs in browser | Likely Yes — credits imply account (“free account = 15 credits; 10 per swap”) | Standard web flow; credit model suggests account creation | Great for instant photo→video swaps; you’ll burn credits quickly (10 per swap). |
| Media.io | No — full web tool | Yes at generate/export (appears no-login at first) | Clear UI; auto-deletes uploads after hours (per site); account gate for full export | Free account: 5 credits; gender-swap video costs 6 (can’t fully try video free). Photo swap often 1 credit. |
| UUININ | No — web flow works | No for a usable download (login only if publishing to community) | Minimal prompts; no forced profile for basic use | Also offers community/monetization (requires account) if you want growth. |
| AiDesign | No — browser prompt editor | No in your test (saw 4 free credits) | Simple UI; minimal friction; no registration prompt seen | Powerful for prompt control & batch stylization; free tier mis-detected face once; full-body → half-body crop. |
| Bylo.ai | No — browser interface | Likely Yes — 5 credits/day & storage suggest account | Transparent about free vs. commercial usage; free = personal use only | Multi-model hub (Gemini 2.5 Flash Image/Nano Banana, GPT-4o Image, Flux); some swaps looked head-large/body-small. |
Every app here can swap gender, but the creator’s experience varies. The biggest win is zero friction—being able to finish the whole workflow in the browser with no sign-up.
One more perk (if you want it): UUININ also lets you share to its community for extra discovery. But even if you skip that, the no-download, no-registration path is what makes it stand out for fast testing and instant cross-platform posting.
