When this tool is useful
Change the file format without needing a desktop image editor. The right choice depends on what is actually wrong with the image. If the dimensions are correct but the file is too heavy, start with compression. If the image is physically larger than the destination needs, resizing can remove unnecessary pixels. If another system requires a different file type, conversion is the appropriate step.
How it works
The core operation runs in your browser using the selected file and the browser's image and Canvas capabilities. The generated result is offered as a local download. This design is intended to avoid a server-side image upload for the core operation.
Common questions
Which format should I convert to?
For photographs, JPG or WebP are common choices. PNG is useful when transparency or lossless graphics matter. The best choice depends on the destination and whether transparency is required.
Will conversion reduce quality?
It can. Converting to a lossy format such as JPG or WebP may discard some image information, especially at lower quality settings.
Why did the file size change after conversion?
Different formats use different compression methods. A visually similar image can therefore have a very different file size after conversion.
