May 12, 2026 Just launched: WebP Batch Optimizer — offline WebP conversion for Windows

Hey IH 👋

After wasting hours on online image compressors (limits, watermarks, slow uploads), I built a simple offline tool for Windows that batch-converts JPG/PNG → WebP.

🔧 What it does:

• Convert entire folders in seconds

• Quality slider + 3 presets (Web / Print HQ / Social Light)

• Dry-run mode to test before saving

• Auto-strip EXIF metadata (privacy + smaller files)

• Real-time log + progress bar

🛠️ Built with:

• Python 3.11 + Pillow for image processing

• tkinter for the GUI (no external dependencies)

• PyInstaller for standalone .exe compilation

• ~300 lines of code, fully open to feedback

👉 Try it here (launch price $5, pay what you want): [link]

❓ Looking for feedback:

• Does the 3-step flow (select → pick quality → go) make sense for non-technical users?

• Would you prefer drag & drop, rename patterns, or a CLI mode?

• Any edge cases I missed? (HEIC support, macOS, large folders >1000 files?)

💡 Why I'm sharing it:

I built this for myself first. Now I'm curious: would other builders find it useful? If it saves you time, great. If not, I'd love to know what's missing.

No pressure — just building in public and learning. Thanks for any thoughts! 🙏

I kept losing hours manually converting product images to WebP for my own projects. Online tools had limits, watermarks, or privacy concerns. So I built a lightweight offline tool that does batch conversion in seconds —
