About PNG format

PNG is a lossless image format that supports transparency, making it ideal for web graphics, logos, and images requiring crisp edges. Developed as a patent-free alternative to GIF, PNG uses efficient compression while preserving every pixel of the original image. It's the go-to format for screenshots, graphics with text, and images where quality cannot be compromised.

Pros

  • +Lossless compression preserves image quality
  • +Full transparency support with alpha channel
  • +Excellent for graphics with sharp edges and text

Cons

  • -Larger file sizes than lossy formats like JPEG
  • -Not ideal for photographs
  • -No animation support (use APNG or GIF instead)

Frequently asked questions

Is it safe to convert PNG to WEBP online?
Yes, Convt processes your files entirely in your browser using WebAssembly. Your files never leave your device - no data is uploaded to any server. This makes it completely private and secure.
How long does PNG to WEBP conversion take?
Conversion is typically instant for small to medium files. Larger files may take a few seconds depending on your device's processing power. Since everything runs locally, speed depends on your hardware rather than internet connection.
Is there a file size limit for conversion?
There's no artificial file size limit. However, very large files (over 500MB for video, 100MB for images) may strain your browser's memory. For best results, ensure you have enough available RAM.
Do I need to install any software?
No installation required. Convt runs entirely in your web browser. It works on any modern browser including Chrome, Firefox, Safari, and Edge on desktop and mobile devices.
Can I convert multiple files at once?
Yes, you can add multiple files to the converter and process them all. Each file will be converted individually and you can download them separately or together.
Will converting PNG to WEBP reduce image quality?
WEBP uses lossy compression, which may slightly reduce quality in exchange for smaller file sizes. For most uses, this difference is imperceptible.
