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.
