1. What does this tool do?

This web-based tool lets you resize, compress, and optimize images directly in your browser. Key features include:

• Adjust width/height dimensions (with aspect ratio locking)
• Set image quality (1-100%)
• Convert between JPG, PNG, and WebP formats
• Apply social media presets (Instagram, Facebook, etc.)
• Target specific file sizes (KB/MB)
• Real-time preview with file size comparisons

2. Are my images uploaded to a server?

No. All processing happens locally in your browser. Your images are never sent to any server, ensuring complete privacy.

3. What file formats are supported?

You can upload:

• JPG/JPEG
• PNG
• WebP
  Output formats: Same as above (selectable).

4. How do I use the target file size feature?

1. Enter desired size (e.g., 250)
2. Select unit (KB or MB)
3. Click Apply
   The tool will automatically adjust quality to meet your target.

5. Why can’t I download my image?

Common reasons:

• No image uploaded yet
• Browser restrictions (try Chrome/Firefox)
• Corrupted image file
• Ad-blockers interfering (disable temporarily)

6. Does this work on mobile devices?

Yes! The interface is fully responsive and works on smartphones/tablets. Performance may vary with very large images.

7. How accurate is the file size reduction?

The reduction percentage is calculated precisely from:

Reduction % = (1 – (New Size / Original Size)) × 100

Actual savings depend on image complexity and format.

8. Can I process multiple images at once?

Not currently. This version processes one image at a time. Refresh the page to start a new session.

9. Why does my resized image look blurry?

Try:

• Increasing quality slider (>80%)
• Using WebP format (better compression)
• Avoiding extreme downscaling (e.g., >50% size reduction)
• Disabling “Maintain aspect ratio” for custom adjustments
