Senior Designers shouldn't be manually-resizing assets ready to run or being aware of TikTok safe zones. PixFit turns 1 key visual into every ad format — brand-perfect, platform-specific, ready to ship.
Hey Product Hunt! 👋
I'm Marco, currently leading GTM at Winclap - a performance advertising company that's been running content production at scale for years.
PixFit started as our internal tool. We were spending serious senior designer hours on one repetitive task every single campaign: adapting a master creative to every media ad format. Safe zones, platform margins, CTA repositioning, background expansion - all manual, all blocking campaigns from going live.
So we automated it, then decided to make it available to everyone.
How it works:
Upload your master creative. PixFit generates every format: brand-aware, safe-zone correct, with optimal branding and CTA placement per platform. The first output is delivered directly. No approval queue. Ready to ship.
The part I'm most proud of: the human fallback.
We could've shipped pure AI and called it done. We didn't.
If an output doesn't meet your standard after 3 AI attempts, you can request a Winclap designer that delivers manually within 24–48h. You always get an output you can ship. It's not "AI with mandatory human QA" — it's AI-first, with a safety net that only activates when you decide you need it.
We're going public for the first time today. Until now, this has only existed as an internal Winclap tool.
What I'd genuinely love to know:
What's your biggest headache in creative production right now? Are we solving the right pain or is there something we're missing?
I'll be here all day answering every comment.
Congrats! The human fallback is a really interesting touch. What percentage of creatives typically need to be escalated to a designer today?
Hi Marco! Having a tool to turn 1 idea into multiple ad formats is life saving. I have one question. Do multiple formats have any negative impact in pixel quality? Congrats on the launch!
La verdad que la herramienta me facilitó un montón parte de la operatividad de mi trabajo diario. Me pareció muy amigable y fácil de usar! Me sirvió más de lo que esperaba! Súper recomendado!
Been waiting for something like this. The worst part of running paid is the creative bottleneck - one good asset and then hours reformatting it into 20 placements before you can actually launch. Curious how PixFit handles the weird ones (Stories vs. feed vs. display banners). Congrats on the launch 🚀
We built PixFit around a problem that sounds simple, but quietly consumes a huge amount of creative-production time:
You have one approved campaign asset. Now you need to rebuild it for every ratio, placement and platform — Meta, Google, TikTok — while preserving the hierarchy, branding, safe zones, logos, CTAs and legal copy.
But the part we cared about most was making it useful in real production, not just impressive in a demo.
AI handles the first pass and automatically retries or fixes most problematic outputs. When it still cannot produce something that meets the required standard, a senior creative steps in and finishes it.
95% resolved with AI. 5% refined by humans. 0% shipped unfinished.
You can try it with your own creative — the free trial includes five resizes and requires no credit card.
Give it something difficult. See where it works, where it struggles and tell us what you would change. That feedback is exactly what we want from this launch.
How does it handle brand fonts and custom typography when generating all those platform variants?
Nice idea, especially the human fallback. How much flexibility is there to tweak the AI generated creatives before exporting them? Also, i sthe human fallback included in the pricing or charged separately? Congratulations!
the human fallback after 3 attempts is the right call honestly, most of these tools pretend the AI output is always good enough and quietly ship the bad crops. curious what the actual failure rate looks like once you have real usage data, not just your own campaigns
I lead the creative operations side at Winclap Studio — the team that actually produces the assets.
Before PixFit existed, we had great designers, solid processes, and still spent an embarrassing amount of time on mechanical adaptation work. The kind where a talented person is manually resizing the same creative into 12 formats at 11pm. Not because they lacked tools — because none of the tools truly understood the workflow behind the creative, not just the creative itself.
That frustration is where PixFit started. We built it first for ourselves, tested it with our own production load, and broke it enough times to know what actually had to work.
What I'm most proud of: we didn't ship a tool that promises 100% automation and quietly fails. We designed for the real number — the 70% you can automate confidently — and built a proper human review layer for the rest. That honesty in the product design is what makes it trustworthy at scale.
If your team is producing performance creatives across formats for multiple brands, you'll feel this immediately. Happy to share how we've been running it internally if anyone wants to dig in 🙏
So the human fallback only kicks in after three AI attempts fail... how do you actually detect that an output "failed" versus just handing me something that technically fits the safe zones but looks off? Curious whether that's a confidence score or purely me hitting a button.
resizing ad creatives across formats is genuinely one of those tasks that eats hours and adds zero creative value. the platform safe zones detail is what makes this useful, anyone can crop an image but knowing where tiktok puts its UI overlays vs where meta does is the actual knowledge being automated. how does it handle text-heavy creatives where a straight resize would break the layout? does it reflow elements or just scale everything proportionally?
Really interesting product!!! Curious.....what's the biggest challenge in keeping creatives brand-consistent across so many different ad formats?
This can be pretty helpful and time-saving. When I want to change something, it can take a pretty amount of time to customise it.
Tried the tool, works clean!
What about videos? that would be great ;)
