How to use it

Drop your JPG/JPEG files into the upload area or choose them from your device. The converter processes the queue one file at a time, so a phone or laptop is not overloaded by a whole batch at once.

Which settings to choose

Keep the original size for editing or archiving. Use 1920 px for websites and 1280 px for quick sharing when the output file should be lighter.

Privacy

Your files are not uploaded to a server. Processing happens in your browser with local scripts from this site.

Limits

Very large images may take longer on phones or older laptops. If the browser runs out of memory, reduce the number of files in the queue or choose a smaller output size.
