Frequently asked questions
How do I convert PNG to JPG?+
Drop the PNG, choose JPG as the output, pick a background colour for any transparent areas, then download.
Can I convert several images together?+
Yes. Add multiple files and they are all converted in one pass, each with its own download button.
Why did my WebP come out as PNG?+
A few browsers cannot encode certain formats. When that happens the tool falls back to PNG so you still get a file.
Are the images uploaded?+
No. Conversion uses the browser canvas and stays on your device.
