Engineered for High-Performance Digital Products

Uncompressed images are the leading cause of sluggish page speeds. Here is why client-side optimization matters.

Zero Data Telemetry

Your sensitive graphics, client mockups, and photos are processed in memory using the HTML5 Canvas API. Files are never uploaded to any third-party cloud.

Next-Gen WebP Standard

Slash bandwidth costs and boost Google Core Web Vitals (LCP) by converting heavy legacy formats into optimized WebP images with superior compression ratios.

Real-Time Visual Tuning

Preview quality changes and byte reduction live before downloading. Dial in the exact trade-off between crisp visual clarity and minimal file size.

Supported Formats & Conversion Matrix

Everything you need for modern web development asset preparation.

  • ICO (Favicon): Generate multi-resolution (16×16 to 256×256) standard website `.ico` favicons from PNG, SVG, or JPEG.
  • HEIC / HEIF: Apple iPhone / iOS raw photo format natively decoded in-browser using WebAssembly.
  • SVG: Scalable vector graphics cleanly rasterized into high-resolution bitmap assets.
  • WebP: Modern web compression standard, supporting both lossy and lossless modes with alpha transparency.
  • PNG: Pixel-perfect lossless compression ideal for screenshots, UI icons, and sharp graphics.
  • JPEG: Universal photographic compatibility across all platforms and legacy devices.

Frequently asked questions

How does the HEIC conversion work?

Apple devices save photos in HEIC/HEIF format. Our tool utilizes in-browser WebAssembly (heic2any) to decode the raw Apple HEIC data locally into standard web image formats without needing any external server processing.

Can I convert vector SVG files into raster WebP/PNG images?

Yes! When you upload an SVG file, the browser parses the vector graphics and rasterizes them cleanly into WebP, PNG, or JPEG at the exact compression level you specify.

Are my uploaded images stored on your servers?

No. All image processing, conversion, and compression happens 100% locally within your web browser using HTML5 Canvas and WebAssembly. Your photos never leave your device.

Which format should I choose for my website?

WebP is recommended for virtually all modern websites. It offers 25-35% better compression than JPEG at comparable visual quality, speeding up page load times and Core Web Vitals.

How does the quality slider affect file size?

For lossy formats like WebP and JPEG, lower quality percentages produce significantly smaller file sizes. A quality setting of 80% usually offers the best balance between sharpness and small file size.
