Frequently asked questions
How do I convert an image to a different format?
Drop your images into the tool above, select the output format (JPEG, PNG, or WebP), adjust the quality slider if needed, then click Convert Images. Your converted files download instantly — no account needed.
Are my images uploaded to a server during conversion?
No. All conversion happens entirely in your browser using JavaScript. Your images never leave your device and are never sent to any server.
What is the difference between JPG, PNG, and WebP?
JPEG is best for photographs with lossy compression and small file sizes. PNG supports transparency and uses lossless compression, ideal for graphics and screenshots. WebP offers both lossy and lossless compression with smaller file sizes than JPEG and PNG, and supports transparency.
Does the quality slider affect PNG output?
No. PNG is a lossless format, so the quality slider has no effect when converting to PNG. The slider only applies to JPEG and WebP output, where lower values produce smaller files with some quality loss.
How many images can I convert at once?
You can convert up to 30 images at once with a total size limit of 500MB. If you convert multiple files, they are packaged into a single ZIP download.
