Frequently Asked Questions
Which image formats can I convert between?
You can convert any browser-supported image (PNG, JPG, WebP, GIF, BMP, SVG) to PNG, JPEG, or WebP. These three output formats cover virtually all web use cases.
What is the best format for web images?
WebP offers the best compression (25-35% smaller than PNG/JPG at equivalent quality) and is supported by all modern browsers. Use PNG when you need lossless quality or transparency, JPG for photographs, and WebP for everything else.
Are my images uploaded to a server?
No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device, making this tool safe for sensitive or confidential images.
Is there a file size or count limit?
There is no hard limit — performance depends on your device. Most browsers handle images up to ~50MB and batches of ~20 files comfortably. Very large images may take a few seconds to process.
