When should you convert image formats?
Image format conversion is useful when you need to share, compress or display images across different platforms. Examples include converting iPhone HEIC photos to JPG for older devices, turning transparent PNG logos into WebP to reduce size, or preparing assets for websites, apps and presentations.
With this online image format converter, you can batch upload images and convert them all to a single output format without installing any software. Over 100 input formats and 7 common output formats are supported, which covers most daily and professional workflows.
Recommended formats for different use cases
For photos, JPEG and WebP are good choices: JPEG has the best compatibility, while WebP often achieves smaller file sizes at similar visual quality. For images that require transparency (logos, icons, UI assets), PNG or WebP/AVIF are recommended. AVIF can deliver excellent quality at very small sizes, making it ideal for performance‑ focused websites.
GIF is suitable for simple animations and memes, while ICO is used for favicons and desktop icons. If you work with professional formats like PSD, TIFF or RAW, you can export them to a standard format locally and then use this tool to convert everything into web‑friendly formats for blogs, portfolios or ecommerce pages.
