Frequently Asked Questions
Are my photos or images uploaded to a cloud server?▼
No, never. The entire image decoding, color conversion, and re-encoding process takes place 100% inside your web browser using HTML5 Canvas and local Blob APIs.
What happens to transparent backgrounds when converting PNG or WebP to JPG?▼
Because the JPEG format does not support transparency, transparent areas are automatically filled with a clean solid background color (defaulting to white).
Why should I convert my images to WebP?▼
WebP provides superior lossless and lossy compression for web images, often reducing file size by 30% to 80% compared to PNG and JPEG without noticeable quality loss.
Can I convert multiple images at the same time?▼
Yes. You can select or drop multiple images at once to convert them simultaneously and download them individually or in batch.
