I Built a Free, 100% Browser-Only WebP to JPG/PNG Batch Converter

Hey community!

👋AI image generators and modern sites export files in .webp format, but many traditional software frameworks, publishing tools, and platforms like Etsy heavily reject them, demanding native formats.To solve this conversion friction instantly without bloated ads, I built a standalone web utility: Preflight WebP to JPG/PNG Converter.

🛠️** Why It’s Different:**

100% Client-Side Processing: Your creative designs are never uploaded to an external server disk. The tool runs completely inside temporary local browser memory using native HTML5 Canvas APIs, keeping your file layouts 100% private.
Optimized Batch Loops: Features fast, concurrent async processing arrays allowing drag-and-drop batch optimization for multiple image files simultaneously.
No Friction: No signups required, no watermarks, no email prompts, and completely free.I built this standalone module to keep design file preparation secure and fast. I’d love to hear your feedback on the batch rendering speeds or UI layout structure.

I Built a Free, Zero-Server Print Size Calculator to Stop Blurry Image Prints

Ever notice a photo looks perfect on your screen but comes out blurry once you print it?

It's usually not the printer's fault — it's a pixel-vs-inches mismatch that nobody checks before hitting print.

I built a free tool that solves this in 10 seconds: enter your image's pixel size (or upload it), and it tells you the largest size you can print at full quality — plus how it holds up against standard photo and poster sizes.

Quick rule of thumb: divide pixel width by 300 to get max inches for a sharp, close-up print. A 3000×2000px photo tops out around 10×6.7in.

Everything runs in your browser — no uploads, no signup, no paywall.

Built this for designers and small print shops who've been burned by a blurry reprint. Would love feedback on what to add next!

I Built a 100% Free Image Compressor & Resizer That Never Saves Your Files to Disk

Hey DEV Community! 👋

As a Full-Stack Developer with 5+ years of experience building web architecture, I constantly look for ways to optimize Core Web Vitals and page speeds. Large images are usually the biggest culprit behind slow loading times.

While there are amazing image optimization tools out there, I got frustrated with two things:

Constant pop-ups to upgrade to premium after a few files.
The uncertainty of where my images are being uploaded and stored.

To solve this for my own client workflows, I built a lightweight side-utility: Preflight Image Compressor & Resizer.

🛠️ How it Works & Why It’s Different:

Strict Privacy (Held in Memory): Unlike typical online converters, your files are never written to a server disk. The image is held in temporary memory during the request cycle and streamed directly back to you as a download.
Two-in-One Processing: You can alter the pixel dimensions (resize) and change the optimization weight (compress) in a single action.
No Friction: No signups, no emails, no watermarks, and 100% free.

💡 Compression Tip:

For standard photography, aiming for 80-90% quality compression is the sweet spot. It drops the payload size significantly with almost zero human-visible degradation. If you are dealing with heavy PNG files, try converting them to WebP first before compressing.

I intend to keep this as a clean, ad-free standalone web utility. I would love to hear your feedback on the compression speeds, processing time, or any features you think I should add next!
