Why Use Utiliti's Image Converter?

Images often contain sensitive content—personal photos, confidential documents, proprietary designs, or screenshots with private information. Many online image converters upload your files to their servers for processing, where they could be stored, analyzed, or exposed.

Utiliti's Image Converter runs entirely in your browser using the Canvas API. Your images never leave your device, making it safe to convert:

  • Personal Photos: Convert family photos without uploading them to unknown servers
  • Confidential Documents: Process scanned documents and screenshots privately
  • Client Work: Handle client assets without violating NDAs or privacy agreements
  • Proprietary Designs: Convert mockups and designs without exposure risk

Features

  • Batch Processing: Convert multiple images at once and download them all as a ZIP file
  • Quality Control: Adjust compression levels from 25% to 100% for the perfect balance of quality and file size
  • Drag & Drop: Simply drag images onto the converter for quick processing
  • Individual Downloads: Download converted images one at a time or all together
  • Preview: See thumbnails of your converted images before downloading

How to Use

  1. Upload images: Click to browse or drag and drop images onto the upload area (max 10MB per image)
  2. Select output format: Choose between JPEG, PNG, or WebP from the dropdown
  3. Adjust quality: For JPEG and WebP, select your preferred compression level
  4. Download: Click individual images to download them, or use "Download As Zip" for batch downloads

Supported Formats

  • JPEG: Best for photographs and complex images. Supports quality adjustment for smaller file sizes.
  • PNG: Best for graphics, screenshots, and images requiring transparency. Lossless compression.
  • WebP: Modern format with superior compression. Supports both lossy and lossless modes. Ideal for web use.

Common Use Cases

  • Web Optimization: Convert images to WebP for faster website loading times
  • Compatibility: Convert WebP images to JPEG/PNG for older applications that don't support WebP
  • Transparency: Convert to PNG when you need to preserve transparent backgrounds
  • File Size Reduction: Use JPEG or WebP with quality adjustment to reduce image sizes for email or storage
  • Batch Conversion: Convert entire folders of images to a consistent format

Quality vs File Size

The quality setting affects the trade-off between image fidelity and file size:

  • 100% (Full): Maximum quality, largest file size
  • 80-90% (High): Excellent quality, good compression. Recommended for most uses.
  • 60-75% (Medium): Good quality, significant size reduction. Great for web thumbnails.
  • 25-50% (Low): Noticeable quality loss but very small files. Use for previews only.
