Frequently Asked Questions
Why convert images to WebP?
WebP produces files 25–35% smaller than JPEG at the same visual quality, and supports lossless compression and transparency like PNG. All major browsers now support WebP natively, making it the best format for web use.
Will converting JPG to PNG make it lossless?
No. When you convert a JPG to PNG, you get a lossless copy of the already-compressed JPG — you cannot recover the original quality that was lost when the JPG was first saved. If you want lossless images, always start from the original source file.
Does PNG support a quality slider?
PNG is always lossless, so the quality slider does not apply. The PNG output will be the highest quality representation of your image. This is why PNG files are often larger than JPG or WebP.
Can I convert multiple images at once?
Yes — drop multiple files or select them all at once. Each image is converted individually and you can download them all with one click. The converter processes them in parallel in your browser.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
