Frequently Asked Questions
How do I convert between image formats?
Select one or more image files, choose your target format from the dropdown (JPG, PNG, WebP, GIF, or BMP), adjust quality settings if applicable, and click Convert. Your converted images will be ready to download instantly.
What image formats are supported?
Our converter supports all major image formats: JPG/JPEG (best for photos), PNG (best for transparency and lossless quality), WebP (best for web with smaller sizes), GIF (for simple animations), and BMP (uncompressed bitmap). You can convert from any format to any other format.
When should I use the quality slider?
The quality slider appears for JPG and WebP output formats, which use lossy compression. Higher quality (85-100%) preserves more detail but creates larger files. Lower quality (60-80%) creates smaller files but may show compression artifacts. PNG, GIF, and BMP formats ignore the quality setting as they use lossless compression.
Which format should I choose for my images?
WebP is recommended for web use (smallest size, modern browsers). PNG is best for images requiring transparency or perfect quality. JPG is ideal for photographs with smaller file sizes than PNG. GIF works for simple animations. BMP is uncompressed and creates very large files, use only when required by specific software.
Can I convert multiple images at once?
Yes! You can select multiple image files and convert them all at once in a batch. The tool will process each file and provide a Download All button that creates a ZIP file containing all converted images with their proper file extensions.
What happens to transparency when converting to JPG or BMP?
JPG and BMP formats do not support transparency. When converting images with transparent areas to these formats, you can choose a background color that will replace all transparent pixels. The default is white, but you can select any color to match your needs.
Are my images uploaded to a server?
No! All image conversion happens entirely in your browser using client-side JavaScript and the Canvas API. Your images never leave your device and are not uploaded to any server, ensuring complete privacy and security.
