Frequently Asked Questions

Are my images uploaded to Pixiva servers?
No. Pixiva runs entirely locally in your web browser using HTML5 APIs. Your files are processed directly on your computer's CPU and GPU and never sent over the internet.
How does visual comparison help?
It allows you to inspect potential compression artifacts. Drag the vertical divider handle left and right to inspect fine details side-by-side before downloading, ensuring perfect quality balance.
Which formats are supported?
We support compression for WebP, PNG, and JPEG/JPG formats. Additionally, iPhone photos (HEIC format) are decoded locally so they can be processed and downloaded as JPGs instantly.
