MiaoCut - Free AI background remover — no watermark, no signup

by•
Drop an image, get a transparent PNG in 1 second. Powered by BiRefNet (the 2024 SOTA segmentation model), so hair, fur, and semi-transparent edges look genuinely sharp. 100% free, no signup, no watermark, no resolution downgrade. A real alternative to remove.bg.

Hey Product Hunt 👋 I built MiaoCut because I got tired of remove.bg charging $9/month for a 5-second task. The thing is, BiRefNet — a SOTA segmentation model published in 2024 — runs perfectly fine on a single $20 VPS. So I packaged it into a no-frills web app and made it completely free. What's actually different from the dozens of other free tools out there: • Most "free" remove.bg alternatives still use U2-Net (2020). MiaoCut runs BiRefNet (2024). Real visible difference on hair, fur, and lace edges — drop in any pet photo and you'll see. • No watermark. No "free preview, pay for HD" trick. The download is full resolution, period. • No signup. No email harvest. No "free tier limits". • Processing is in-memory. The image is never written to disk and is gone the moment the response is sent. The source code's right there in the network tab if you want to verify. This is a one-person side project. The only ongoing cost is the VPS + CDN, both of which are cheap. As long as it doesn't get DDoSed, it stays free. What I'd love from this community: 1. Try it on your hardest image — the one remove.bg fumbled on. If MiaoCut also fumbles, send it to me and I'll dig into why. 2. Honest feedback on the UX. The whole UI is one HTML file, so changes ship fast. Thanks for taking a look 🙏 — Wu Chao

I've been working hard on expanding MiaoCut. It started as a background remover using BiRefNet, but I noticed people (and myself) needed more everyday photo utilities.

What I've added this week:

  • Object/Watermark Eraser: Integrated SimpleLama to let users paint over unwanted elements and magically erase them.

  • Automated ID Photo Generator: This was surprisingly fun to build. It uses face-landmark detection to find the eyes and chin, auto-scales the head to meet strict passport photo ratios, replaces the background, and generates a printable layout.

  • Old Photo Enhancer: Uses OpenCV pipelines (and external AI providers) to denoise, sharpen, and upscale old family photos.

Tech stack: Python, FastAPI, Hugging Face Spaces for the backend, and vanilla JS + TailwindCSS for a super lightweight frontend hosted on Cloudflare Pages.

It's 100% free with no login required. I'd love for you guys to try it and try to break it. I added a global feedback widget—let me know what UI/UX improvements I can make!

Hey everyone!

A while ago I launched MiaoCut as a simple background remover. Today, I'm super excited to announce a massive update. I wanted to build a single place for everyday image tasks without the annoying paywalls or "sign up to download" popups.

Here is what's new:

  1. Magic Eraser (Object Removal): Brush over unwanted objects, text, or photobombers, and the AI seamlessly removes them.

  2. ID Photo Maker: Turns any selfie into a professional passport or ID photo. It auto-detects your face, aligns your eyes, changes the background to blue/white/red, and even generates a printable layout sheet so you can print it at a local pharmacy for cents instead of $15.

  3. Old Photo Restoration: Upscales and enhances old, noisy, or blurry photos.

  4. Pro Background Removal: Dedicated algorithms for e-commerce products or LinkedIn headshots (retains crazy hair details!).

The site is completely free, processes images quickly, and we don't store your photos (privacy-first).

Would love to hear your feedback! I even added a little coffee cup feedback button on the site so you can tell me what to build next.
