Frequently Asked Questions

What image formats can I convert between?

Our image converter supports JPEG, PNG, WebP, BMP, and GIF formats. You can convert from any of these formats to JPEG, PNG, or WebP output formats. Each format has specific advantages - JPEG for photos, PNG for graphics with transparency, and WebP for modern web optimization.

How does the image converter maintain quality?

We use the Pica library for high-quality image processing, which provides superior resizing and conversion algorithms. You can control the output quality from 10% to 100%, with 90% being the default for an optimal balance between file size and visual quality.

What happens to transparent backgrounds during conversion?

PNG and WebP formats support transparency, while JPEG does not. When converting from a transparent format to JPEG, you can choose a custom background color to replace transparent areas. The tool automatically detects transparency and provides color selection options when needed.

Which format should I choose for my images?

JPEG is best for photographs and images with many colors. PNG is ideal for graphics, logos, and screenshots that need transparency or lossless quality. WebP is a modern format that offers superior compression for web use, supporting both lossy and lossless compression with transparency.

Is my image data secure during conversion?

Yes, all image conversion happens client-side in your browser using JavaScript. Your images are never uploaded to our servers, ensuring complete privacy and security. The conversion is processed entirely on your device.

What is the maximum file size for conversion?

You can convert images up to 100MB in size. This generous limit accommodates high-resolution photos and professional images while ensuring fast processing performance.

Can I batch convert multiple images at once?

Currently, the tool processes one image at a time for optimal quality control and preview. However, the conversion is very fast, and you can quickly convert multiple images sequentially by clearing and uploading new files.

What keyboard shortcuts are available?

The image converter supports Ctrl+O to open and select a file, and Ctrl+S to download the converted result. These shortcuts help speed up your workflow when converting multiple images.
