Frequently Asked Questions
Why convert JPG to PNG?
PNG is ideal when you need lossless quality, transparency support, or better preservation of sharp edges and text. While JPG is great for photos, PNG excels at graphics, logos, screenshots, and images with text. PNG also supports alpha channel transparency, making it perfect for overlays, logos, and web graphics.
Will converting JPG to PNG improve image quality?
No, converting JPG to PNG won't recover quality lost during JPG compression. However, it prevents further quality loss if you need to edit the image. JPG uses lossy compression, and any quality already lost cannot be recovered. PNG will preserve the current state without additional degradation.
Will PNG files be larger than JPG?
Usually yes, because PNG uses lossless compression while JPG uses lossy compression. PNG files are typically 2-5x larger than equivalent JPG files, especially for photos. However, for graphics, screenshots, and images with large areas of solid color, PNG can sometimes be smaller and always provides better quality.
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 in your browser using JavaScript. Your images never leave your device and are never uploaded to our servers. This makes our converter completely private and secure. Your images remain on your computer at all times.
How many images can I convert at once?
You can convert up to 100 JPG images to PNG in a single batch. There's no daily limit or subscription required - it's completely free and unlimited. For large batches, we use efficient memory management to ensure smooth processing even on older devices.
Does converting preserve EXIF metadata?
By default, EXIF metadata (camera settings, location, etc.) is removed during conversion for privacy. However, you can choose to preserve EXIF data using our metadata options if you need to keep this information. PNG files can store EXIF data, though it's less common than in JPG files.
