Frequently Asked Questions

HelPNG is a free online image conversion tool that allows you to convert between PNG, JPEG, and WebP formats. You can convert individual images or process multiple files at once (batch conversion) directly in your browser without creating an account.

Yes! HelPNG is completely free to use. There are no hidden fees, subscriptions, or premium plans. You get full access to all conversion features without any cost.

No account required! Simply visit the website, upload your images, choose your desired output format, and download the converted files. It's that simple.

WebP is a modern image format that provides superior compression compared to PNG and JPEG while maintaining high quality. It supports both transparency (like PNG) and excellent compression (better than JPEG), making it ideal for web use. WebP files are typically 25-50% smaller than equivalent PNG or JPEG files.

These limits ensure optimal performance for all users and prevent server overload. Image conversion is memory-intensive, especially for large files. These limits allow us to provide fast, reliable conversion while maintaining service availability for everyone.

Yes! You can upload and convert up to 10 files simultaneously. This batch processing feature saves time when you need to convert multiple images to the same format. The system processes files efficiently and provides a progress indicator during conversion.

Conversion time depends on file size and quantity. Small images (under 1MB) typically convert in seconds, while larger files may take longer. Batch conversions are processed efficiently with smart memory management to ensure optimal performance.

Yes! All data transmission uses HTTPS encryption. Your images are processed securely on our servers and immediately deleted after conversion. We implement industry-standard security practices to protect your data during the brief processing period.

We use Google Analytics to understand how our service is used and to improve user experience. No personal information or image content is tracked. You can opt out of analytics in your browser settings. See our Privacy Policy for complete details.

Quality differences occur due to format characteristics. JPEG uses lossy compression, so converting from PNG to JPEG may reduce quality. Converting to WebP typically maintains better quality at smaller file sizes. For best quality preservation, convert from lossy formats (JPEG) to lossless formats (PNG), though file sizes will be larger.

HelPNG works on all modern browsers including Chrome, Firefox, Safari, and Edge. For the best experience, we recommend using the latest version of your preferred browser. JavaScript must be enabled for the conversion interface to function properly.

Our batch processing system intelligently manages memory usage by processing files in smaller groups when needed. This ensures reliable conversion even with multiple large files. The system automatically adjusts batch sizes based on file characteristics and server capacity to provide optimal performance.
