About ImgPrism

Who We Are

We are an independent development team dedicated to building free, practical, and privacy-respecting online tools. ImgPrism was created out of a simple frustration: most free image editing websites require you to upload your photos to their servers, with no transparency about what happens to your data afterward.

Our Mission

We believe everyone deserves access to high-quality image processing tools without sacrificing their privacy. That is why every tool on this site — compression, resizing, format conversion, cropping, watermarking, Base64 encoding, and rotation — runs entirely in your web browser using the HTML5 Canvas API.

Your images are never uploaded to any server. When you close the tab, your data is gone. We cannot see, access, or recover your images at any point. This is not a marketing claim — it is how the technology fundamentally works.

Why Free?

We sustain this project through non-intrusive advertising. This allows us to keep all tools completely free with no registration, no file size limits, and no watermarks on your output. We believe that basic image processing should not require a paid subscription or an account.

What Makes Us Different

  • Zero uploads: All processing happens locally in your browser. No image data ever leaves your device.
  • No account needed: Use any tool instantly. No sign-up forms, no email verification, no passwords.
  • All major formats: JPEG, PNG, WebP, BMP, and GIF support across all tools.
  • Works everywhere: Desktop, tablet, or phone — any modern browser is all you need.
  • Fast and lightweight: Powered by your browser's native Canvas API. No server round-trips, no upload/download waiting.

Our Tools

We currently offer seven browser-based image tools, each designed for a specific task:

  • Compress Image — Reduce file size by up to 80% without visible quality loss.
  • Resize Image — Change dimensions by pixels or percentage while maintaining quality.
  • Convert Format — Convert between JPEG, PNG, and WebP instantly.
  • Crop Image — Select and crop any area with precise control.
  • Add Watermark — Overlay custom text on your images with adjustable style.
  • Base64 Encode/Decode — Convert images to Base64 strings or decode them back.
  • Rotate & Flip — Rotate 90, 180, 270 degrees or flip horizontally/vertically.
