What You Get
Common Use Cases
WebP images are 25–35% smaller than JPG at equivalent quality. Converting your site images to WebP improves Core Web Vitals and page load speed.
Need a transparent background? Convert JPG to PNG to unlock transparency support, then use an editor to remove the background.
Some old systems, printers, and CMS platforms only accept JPG. Convert PNG or WebP to JPG for maximum compatibility.
Certain Windows applications, embedded systems, and design tools require BMP format — convert any modern image format to BMP instantly.
What is the difference between JPG and PNG?
JPG (JPEG) uses lossy compression — it discards some image data to achieve smaller file sizes, making it ideal for photographs. PNG uses lossless compression — all data is preserved, files are larger, but quality is perfect. PNG also supports transparency (alpha channel); JPG does not. Use JPG for photos, PNG for screenshots, logos, and graphics with sharp edges or transparent backgrounds.
Should I use WebP or JPG for my website?
WebP is the better choice for modern websites — it produces files 25–35% smaller than JPEG at equivalent quality and supports transparency like PNG. WebP is supported by all major browsers (Chrome, Firefox, Safari, Edge). Use JPG only when you need broad compatibility with legacy systems, email clients, or non-web software that doesn't support WebP.
How do I convert a PNG to JPG without losing quality?
Upload your PNG file, select JPG as the output format, set quality to 90–95%, and click Download. Note that any transparent areas in the PNG will become white in the JPG — JPG does not support transparency. If transparency needs to be preserved, convert to WebP instead.
