Frequently Asked Questions
Common questions about using this free online image format converter.
Why should I convert PNG or JPEG images to WebP? ▾
WebP is Google's modern web image format. It is supported by 98%+ of all browsers and provides 25%–35% smaller file sizes than JPEG at equivalent quality, significantly accelerating website load speeds.
What happens to transparent backgrounds when converting PNG to JPEG? ▾
Because JPEG does not support transparency, transparent background pixels are automatically replaced with a clean white (or custom selected) solid background color.
Can I convert animated GIFs to WebP or static images? ▾
Yes. Converting an animated GIF to JPEG/PNG extracts the primary first frame, while converting to WebP produces an ultra-compact single-frame or multi-frame image.
Does this converter upload my photos to any remote server? ▾
No! All decoding, color space transformation, and encoding take place strictly inside your browser's local JavaScript engine.
