Is this JPEG converter secure?
Yes. Files are processed locally in your browser. Nothing is uploaded to a server, so your images stay on your device.
What formats can I convert JPEG to?
You can convert JPEG to PNG, WebP, PDF, or Base64 text. You can also crop JPEGs, compress a single JPEG, or batch-compress multiple JPEGs into a ZIP file.

Yes. Use Compress image for one file, Compress images (batch) for multiple files, or Crop image with the interactive crop box on the preview.
Does the converter work on mobile?
