How to Convert Images Click Select Images, or drag and drop multiple images onto the page. You can also use the copy and paste shortcut to add multiple images. Choose your desired output format and click Convert. When the conversion is complete, you can Save All images at once or view an image and make adjustments in the editor.
Common Image Format Conversion Use Cases Different devices, websites, and applications support different image formats, so converting images from one format to another is often necessary. For example, converting HEIC to JPG improves compatibility with devices and platforms that do not support HEIC. Converting PNG or JPG to WebP or AVIF can help reduce image file size for websites, while converting WebP to JPG or PNG makes images easier to use with software and platforms that do not support WebP. Image format conversion is commonly used for websites, image uploads, file sharing, and everyday image editing.
How Image Conversion Works in a Browser Modern browsers can read and display common image formats such as JPG, PNG, WebP, and AVIF using built-in web technologies such as Canvas and ImageBitmap. These browser APIs allow images to be loaded directly on your device and passed to an image processing engine for format conversion. This makes it possible to convert images directly in your browser without uploading them to a server.
Benefits of Using WASM for Image Conversion WebAssembly (WASM) is a high-performance technology that allows code to run directly in the browser. Combined with the open-source ImageMagick image processing engine, WASM makes it possible to convert many image formats locally on your device without uploading files to a server. Large, high-resolution images require more processing power and memory, so conversion speed may vary depending on your device. We have optimized the converter for large images, but processing a reasonable number of large files at once can help maintain stable performance.
Local Image Conversion vs. Server-Side Conversion Local image conversion takes place directly in your browser, so your images do not need to be uploaded to a server or downloaded again after processing. This can reduce network transfers and save server bandwidth. With server-side conversion, images must first be uploaded to a server, processed, and then downloaded. Browser-based WASM conversion is well suited for common image conversion tasks, while extremely large files or complex processing tasks may be better suited to server-side processing.
Will Image Conversion Reduce Image Quality? Whether image quality changes depends on the input and output formats. Converting between lossless formats can preserve the original image data, while converting to a lossy format such as JPG may result in some quality loss. We aim to preserve the original image dimensions and visual quality whenever possible.
Will the Transparent Background Be Preserved? It depends on whether the output format supports transparency. PNG, WebP, and AVIF can preserve transparent backgrounds, while JPG does not support transparency. When a transparent image is converted to JPG, transparent areas must be rendered as an opaque background.
Why Is AVIF Conversion Slower? AVIF uses more advanced image compression technology and can often produce smaller files at a similar level of visual quality. However, AVIF encoding requires more computational resources, so it is typically slower than JPG, PNG, or WebP conversion. When converting images locally in your browser, processing speed also depends on your device's CPU and available memory. Large, high-resolution images may take longer to convert.
