Convert Format
Convert images between PNG, JPG, WebP and AVIF directly in the browser.
About this tool
Convert Format transforms images between PNG, JPG, WebP, and AVIF formats without installing any software. The conversion happens in the browser itself using the Canvas API, meaning no files are transmitted over the internet.
To convert, drag or select one or more images, choose the target format (PNG, JPG, WebP, or AVIF), and confirm. The tool accepts a wide variety of input formats: JPG, PNG, WebP, AVIF, GIF, BMP, SVG, TIFF, and ICO, among others. In batch mode, all images are converted to the same chosen format and made available for download as a ZIP.
Situations where conversion is needed: turning transparent PNGs into JPGs for platforms that don't support transparency, converting images to WebP or AVIF to reduce file size on websites and improve Core Web Vitals, exporting BMP or ICO icons as PNG for editing in modern tools, and preparing visual assets in a specific format required by content management systems.
Keep in mind that JPG is a lossy format — converting a PNG to JPG and back to PNG will introduce some quality degradation. Choose WebP when you want good compression with transparency support; choose AVIF for maximum compression with equivalent visual quality.
