ZeroPNG - From a single image compressor to 12 browser-native tools

When I built ZeroPNG, it was one tool: compress an image. Drop it in, get a smaller file. That was it.

Over the past few months, I kept adding "just one more tool", and quietly ZeroPNG became something different.

Today it has 12 tools, all running entirely in the browser with zero uploads:

• Image Compressor - PNG, JPG, WebP, AVIF up to 90% smaller
• Image Converter - convert between any format
• HEIC Converter - iPhone photos → JPG/PNG, instantly
• Image Resizer - batch resize with aspect ratio lock
• Crop & Resize - freehand or fixed-ratio crop
• Remove EXIF Data - strip location, device info, and metadata
• Watermark - single-image watermarking
• Bulk Watermark - stamp your brand across a whole batch
• Image to Base64 - encode images for embedding in code
• SVG Converter - convert SVG files to raster formats
• Images to PDF - bundle images into a single PDF
• Web Image Analyzer - audit your images for web performance

The core promise hasn't changed: nothing touches a server.

Every operation runs locally in your browser.

✅ No account required
✅ No file size limits
✅ No privacy trade-offs

I'm sharing this here because dev.to is where ZeroPNG got its first real users, and it felt right to come back and say: it grew.

Would love your feedback on what tool you'd want to see next.
