Frequently Asked Questions
Why convert PNG to JPG?
JPG files are much smaller than PNG files, making them ideal for web use, email attachments, and sharing on social media. Converting PNG to JPG can reduce file size by 70-90%, significantly improving loading times and saving storage space. JPG is the best choice for photographs and images without transparency.
How much smaller will my JPG files be?
Typically, JPG files are 70-90% smaller than PNG files. For example, a 5MB PNG might become a 500KB JPG at 90% quality. The exact reduction depends on the image content - photos compress better than graphics with sharp edges or text. You can adjust quality settings to balance file size and visual quality.
Will I lose quality when converting PNG to JPG?
JPG uses lossy compression, so some quality loss is inevitable. However, at high quality settings (80-90%), the difference is usually imperceptible to the human eye. Our converter defaults to 85% quality, providing an excellent balance between file size and visual quality. You can adjust this setting based on your needs.
What happens to PNG transparency when converting to JPG?
JPG doesn't support transparency. Any transparent areas in your PNG will be replaced with a solid color (usually white) during conversion. If you need transparency preserved, consider converting to WebP instead, which supports transparency and offers excellent compression.
Can I resize images while converting?
Yes! ConvertFast allows you to resize images during conversion. Choose custom dimensions, resize by percentage, or select from social media presets like Instagram (1080×1080), Facebook, Twitter, YouTube, and more. You can maintain aspect ratio or specify exact dimensions. This is perfect for optimizing images for web, social media, or reducing file sizes.
Is it safe to convert images online?
With ConvertFast, absolutely! All conversion happens entirely in your browser using JavaScript. Your PNG images never leave your device and are never uploaded to any server. This ensures complete privacy and security. The conversion is performed using your browser's built-in Canvas API.
Can I batch convert multiple PNG files?
Yes! You can convert up to 100 PNG images to JPG simultaneously. Simply select multiple files or drag and drop an entire folder. All images will be processed in parallel for maximum speed, and you can download them individually or as a single ZIP file for convenience.
