Handling images can often lead to frustrating scenarios:

  • You want to compress an image but hesitate to upload it to online sites, worrying about privacy.
  • Your iPhone's HEIC/PNG photos are too large, and you need to convert them to WebP for sharing.
  • You want to scrub GPS location from a photo before posting on social media but lack the right tool.
  • As a creator, you need to watermark a batch of images but don't want to install bloated software like Photoshop.

If you face these issues, Image Lab is designed for you. It's a professional image processing suite that runs entirely in your browser, featuring Privacy, Speed, and Zero Installation.

Core Features

1. Privacy Scrubber

Scenario: You want to share a home photo on social media without revealing your address (GPS) or device details.

Image Lab's Privacy Scrubber strips this hidden data in one click:

  • Remove GPS Coordinates: Prevent location leaks.
  • Remove Exif Data: Erase camera device, shutter speed, and other parameters.
  • Preserve Quality: Only metadata is processed; visual quality remains untouched.

2. Converter

Scenario: A website loads too slowly, or a platform doesn't support PNG/HEIC uploads.

Support conversion between JPG, PNG, WEBP, and AVIF. We highly recommend trying the AVIF format, which preserves high quality while reducing file size incredibly (often 50% smaller than JPEG).

3. Smart Compressor

Scenario: Beyond format conversion, you need to further reduce file size to save bandwidth.

Precise control over image Quality and Scale. Preview the compressed effect and size in real-time within your browser until it's perfect.

4. Watermark Protection

Scenario: You need to declare copyright before sharing your work.

No need to open Photoshop. Add text watermarks to batches of images directly in the browser. Supports custom color, opacity, rotation, and position.

Why Choose Image Lab?

There are many online image tools, so what makes Image Lab different?

  1. 100% Local Privacy: This is the most crucial difference. Your images never leave your device. All processing happens within your browser's WebAssembly container. No server uploads, absolutely secure.
  2. Lightning Fast: Eliminate upload and download times. Processing speed depends solely on your device. For batch processing hundreds of images, the speed advantage is massive.
  3. Free & Open Source: No "3 free trials" limit, no VIP paywalls.
