About image file conversion

Image conversion lets you change a picture from one format to another (for example JPEG to WebP or PNG to JPEG). This helps reduce file size, preserve transparency, improve page speed, and meet platform requirements while keeping visual quality.

Popular image conversions

• JPG to WebP – modern compression with great quality.
• PNG to WebP – smaller files while keeping transparency.
• HEIC to JPEG – make iPhone photos widely compatible.
• WebP to PNG – export WebP with alpha channel support.
• TIFF to PNG – share lossless images on the web.
