Frequently Asked Questions
How can I resize my images?
Our tool allows you to easily resize images while maintaining quality. You can specify dimensions or reduce file size to a target like 20KB. The quality slider helps you balance size and quality perfectly.
What image formats are supported?
We support conversion between WebP, AVIF, JPEG, PNG, GIF, BMP, and ICO formats. Popular conversions include WebP to JPG, PNG to WebP, JPG to PNG, AVIF to JPG, WebP to PNG, and PNG to ICO for favicons.
Can I create a real favicon (.ico) file?
Yes. Unlike many free converters that simply rename a PNG file with a .ico extension, PhotoConvert generates a genuine ICO file with proper icon headers, so it works correctly as a browser favicon, Windows shortcut icon, or app icon. See our PNG to ICO favicon generator guide.
Is there a file size limit?
The maximum image dimensions supported are 10000x10000 pixels. File size limits depend on your browser's memory capabilities.
Is my data secure?
Yes! All conversions happen locally in your browser. Your images are never uploaded to any server. Read our Privacy Policy for details.
What quality setting should I use?
For web images, 80-90% usually provides a good balance between quality and file size. For professional use, you might want to use 90-100%. See our guide on reducing image size without losing quality.
