Which image format is best for websites?

WebP is the modern standard — up to 35% smaller than JPG with equivalent quality, and supports transparency like PNG. Use JPG for photographs where transparency isn't needed, PNG for logos/graphics needing transparency.

Will converting from JPG to PNG improve quality?

No. JPG compression is lossy — converting to PNG doesn't restore lost data. PNG is lossless going forward, meaning no further quality loss, but the original JPG compression damage remains.

Can I convert a JPG to a transparent background PNG?

Converting JPG to PNG doesn't create transparency — it just changes the container format. JPG has no transparency channel. To remove a background, use an image editing tool that supports background removal.

What is the difference between GIF and WebP for animations?

Animated WebP supports full colour (16 million colours) and transparency, with much better compression. Animated GIF is limited to 256 colours but has universal support. Use animated WebP where supported, GIF as fallback.

Does this tool upload my images to a server?

No. All conversion happens in your browser using the HTML Canvas API. Your images remain private and are never sent to any external server.
