Frequently Asked Questions
- Which image format should I choose for my needs?
- Use JPEG for photos (smaller files), PNG for graphics with transparency, WebP for modern web use with excellent compression, GIF for simple animations, and TIFF for high-quality archival purposes.
- Can I convert multiple images at once?
- Yes! Our batch processing feature allows you to upload and convert multiple images simultaneously with the same settings, saving time and ensuring consistency across all files.
- What happens to transparency when converting to JPEG?
- JPEG doesn't support transparency, so transparent areas will be filled with your chosen background color (white by default). Use PNG or WebP to preserve transparency.
- Can I resize images during conversion?
- Yes, you can resize images by percentage, specific dimensions, or target width/height. The tool can maintain aspect ratios automatically to prevent distortion.
- How do quality settings affect file size?
- Higher quality settings preserve more image detail but create larger files. For web use, 80-85% quality usually provides the best balance between file size and visual quality.
