Frequently Asked Questions — PNG to JPG
Clear answers to common questions about methodology, edge cases, and privacy.
What happens to transparent areas when converting PNG to JPG?
Because JPEG does not support alpha transparency, transparent pixels are filled with a crisp white background.
Are my images uploaded to any cloud server during processing?
Never. The PNG to JPG Converter decodes and re-encodes images directly inside your browser using the HTML5 Canvas API and local Blob URLs, ensuring complete privacy and zero upload latency.
Does client-side conversion strip EXIF metadata automatically?
Yes. Rendering an image onto an HTML5 Canvas and exporting a new JPEG, PNG, or WebP file naturally strips embedded camera EXIF and GPS location metadata.
