Is PNG to JPG conversion free?

Yes, our PNG to JPG converter is completely free with no file limits, no watermarks, and no sign-up required. Convert as many files as you need.

Why is my JPG file larger than the original PNG?

This can happen if your PNG has few colors or large transparent areas. PNG uses lossless compression optimized for graphics, while JPG is better for photographs. Try adjusting the quality slider to reduce JPG file size.

What quality setting should I use for JPG?

For most uses, 85-90% quality provides an excellent balance between file size and visual quality. Use 90-100% for professional photography, or 70-85% for web images where smaller file size is important.

Does JPG support transparency like PNG?

No, JPG doesn't support transparency. When converting from PNG, transparent areas will be replaced with a white or black background. If you need transparency, consider converting to WebP instead.

Can I convert multiple PNG files to JPG at once?

Yes! Our bulk converter supports up to 50 PNG files simultaneously. Just select all your files, adjust quality settings, and convert them all in one go.

Is my data safe when converting PNG to JPG?

Your files are completely safe. All conversions happen locally in your browser - your images never get uploaded to our servers or leave your device. We have zero access to your files.

Why Convert PNG to JPG?

JPG (JPEG) is the most widely-used image format for photographs and complex images. While PNG offers lossless compression, JPG provides significantly smaller file sizes through lossy compression, making it ideal for web publishing, email attachments, and social media where file size matters.

Best Use Cases for JPG

• Web Publishing: Faster page load times due to smaller file sizes
• Photography: Excellent for photos with millions of colors
• Email & Messaging: Reduced file sizes for quick uploads
• Social Media: Optimized for platforms like Instagram, Facebook, Twitter
• Storage: Save disk space for large image collections

Bulk Mode Features Explained

🎯 Quality Slider (50% - 100%)

Recommendation: 85% for photos, 70-80% for web graphics, 90-95% for print-quality images

What it does: Sets background color for transparent PNG areas (JPG doesn't support transparency).

Tip: Use white (#FFFFFF) for general use, or match your website background color

🤖 Auto-Optimize Mode

What it does: Automatically analyzes each image and chooses optimal quality settings. Larger files get lower quality, smaller files get higher quality.

📐 Batch Resize

What it does: Resizes ALL images to the same dimensions before converting to JPG.

Example: Set 1920×1080 to resize all images to Full HD resolution. Great for creating consistent thumbnails or web images.

What it does: Automatically renames all converted files using a pattern.

Patterns:

• {name} = Original filename without extension

• {index3} = Zero-padded: 001, 002, 003... (max supported)
• ⚠️ Do not use {index4} or higher - unsupported placeholders will cause duplicate filenames and ZIP download issues
• Example: photo_{index3} → photo_001.jpg, photo_002.jpg, photo_003.jpg
