🎨 Image Conversion Complete Guide
JPG to PNG Conversion
Best for: Adding transparency to photos, preparing images for design work, preserving quality
Step-by-Step Process:
- Upload JPG files: Drag and drop or click to select multiple JPG files
- Preview conversion: See before/after comparisons in real-time
- Batch convert: Process multiple files simultaneously
- Download results: Get individual PNG files or a ZIP archive
💡 Pro Tips:
- File size increase: PNG files are typically 3-5x larger than JPG due to lossless compression
- Quality preservation: Every pixel is preserved exactly—no quality loss
- Transparency ready: PNG files support transparency for future editing
- Best practices: Use PNG for graphics, logos, screenshots; keep JPG for photos
PNG to JPG Conversion
Best for: Reducing file sizes, sharing photos, email attachments, web optimization
Quality Control:
🔴 Low Quality (50-60%)
- Smallest file sizes (good for thumbnails)
- Visible compression artifacts
- Best for: Email thumbnails, quick previews
🟡 Medium Quality (70-80%)
- Good balance of size and quality
- Suitable for most web use
- Best for: Social media, websites, blogs
🟢 High Quality (85-95%)
- Minimal quality loss
- Larger file sizes
- Best for: Professional photos, printing
⚠️ Important Note: Transparency Loss
JPG format doesn't support transparency. Transparent areas will be filled with a background color (usually white). Consider keeping a PNG backup if you might need transparency later.
WebP Conversion
Best for: Modern web applications, mobile apps, bandwidth optimization
WebP Advantages:
- Superior compression: 25-35% smaller than JPEG, 50% smaller than PNG
- Supports transparency: Like PNG but with better compression
- Animation support: Better than GIF with smaller file sizes
- Quality options: Both lossy and lossless compression modes
🌐 Browser Compatibility

No! All processing happens locally in your browser using advanced web technologies. Your files never leave your device, ensuring complete privacy and security.
What browsers are supported?
We support all modern browsers: Chrome 60+, Firefox 55+, Safari 12+, and Edge 79+. Internet Explorer is not supported.

There are no artificial limits, but performance depends on your device. We recommend files under 50MB each for optimal performance. Very large files may take longer to process.
Can I use PixNmerge on mobile devices?
Yes! Our tools work on smartphones and tablets. Performance may be slower than desktop computers, especially for large files or batch processing.
Technical Questions
What image formats do you support?
Input formats: JPEG, PNG, WebP, BMP, GIF (static). Output formats: JPEG, PNG, WebP. We're continuously adding support for more formats like AVIF, HEIC, and TIFF.
Do you preserve image metadata (EXIF)?
By default, we remove metadata to reduce file sizes and protect privacy. You can choose to preserve metadata in the advanced settings of each tool.
How does the compression algorithm work?
We use industry-standard compression algorithms: JPEG uses DCT compression, PNG uses DEFLATE, WebP uses VP8/VP9. Our algorithms are optimized for the best balance of size and quality.
Can I convert animated images?
Currently, animated GIFs are converted to static images. Full animation support for GIF to WebP conversion is coming soon!
Do you support color profiles?
Yes! We preserve color profiles by default for accurate color reproduction. You can choose to convert to sRGB for web optimization in the advanced settings.
Privacy & Security
How do you ensure my files are secure?
All processing happens locally in your browser. Files never leave your device, and we have no access to your content. This eliminates most security risks associated with online file processing.
Do you collect any data about my files?
No! We don't see, analyze, or collect any information about your files. We may collect anonymous usage analytics (like which tools are most popular) but never file content or metadata.
What happens to files after I close the browser?
All files and processed results are automatically cleared from browser memory when you close the tab or navigate away. Nothing persists on your device unless you explicitly download it.
Is it safe to process sensitive documents?
Yes! Since processing is entirely local, sensitive files never leave your device. However, we still recommend following your organization's security policies for handling confidential material.
