How It Works

Client-Side Processing

This tool uses the HTML5 Canvas API built into your browser. When you select images:

  1. 1.Images load into browser memory (never uploaded)
  2. 2.Canvas API draws and re-encodes in chosen format
  3. 3.Converted image downloads directly to your device

Your Privacy is Protected

This tool runs entirely in your browser using the Canvas API. Your images are never uploaded to any server, stored, or transmitted over the internet. All conversion happens locally on your device in milliseconds.

Frequently Asked Questions

What image formats are supported?
You can convert TO: JPEG, PNG, or WebP. Input formats supported: JPEG, PNG, WebP, BMP, GIF, and ICO. The tool automatically handles transparency for PNG conversions.
Will converting affect image quality?
PNG is lossless, so quality is preserved. JPEG and WebP are lossy formats where you can adjust the quality slider (1-100%). Higher quality means larger files but better image appearance. The default 92% setting provides excellent quality while reducing file size.
What's the maximum file size?
You can convert images up to 50MB in size. You can process up to 20 images at once. This ensures optimal performance in the browser.
Does this work offline?
Once the page loads, all conversion happens locally using browser APIs. However, you need an initial internet connection to load the page. After that, no network activity occurs during conversion.
Which format should I choose?
JPEG: Best for photos, offers smallest file sizes. PNG: Best for graphics, logos, or when you need transparency. WebP: Modern format with excellent compression, ideal for web use (not supported by older browsers).
