Why convert image formats?
Every image format has trade-offs. JPG is universally supported and ideal for photographs, but it uses lossy compression — every save degrades quality slightly. PNG preserves every pixel with lossless compression, which makes it perfect for screenshots, logos, and graphics with text, but files tend to be large. WebP, developed by Google, combines the best of both: it produces files 25–35% smaller than JPG at equivalent visual quality and supports transparency like PNG.
Choosing the right format depends on where the image will be used. A product photo on an e-commerce site benefits from WebP's smaller file size, which means faster page loads and better Core Web Vitals scores. A logo destined for print or a design file should stay as PNG to avoid compression artifacts. And if you're emailing images to someone who might open them on an older device, JPG remains the safest choice for compatibility.
When to use each format
- JPG — Best for photographs, social media uploads, and email attachments. Universally supported on every device and platform.
- PNG — Best for screenshots, logos, icons, and any image with text or sharp edges. Lossless, so no quality loss, but larger files.
- WebP — Best for websites and web apps. Smaller than JPG with better quality. Supported by all modern browsers since 2020.
How browser-based conversion works
This tool uses the HTML5 Canvas API to decode your image and re-encode it in the target format. When you convert PNG to WebP, for example, the browser reads the PNG pixels into a canvas element, then exports them as a WebP file using the canvas.toBlob() method. The quality slider controls the compression ratio for lossy formats (JPG and WebP). At 100%, you get near-lossless output; at 80%, you get a good balance of quality and file size.
Because everything happens in your browser, there are no file size limits imposed by a server, no upload queues, and no risk of your images being stored on someone else's infrastructure. This is especially important for sensitive documents, client photos, or proprietary design assets.
FAQ
- Does converting change image quality?
- Converting to JPG or WebP uses lossy compression — you control the quality with the slider. Converting to PNG is lossless and preserves every pixel.
- Why convert PNG to WebP?
- WebP files are typically 25-35% smaller than PNG with equivalent quality. Great for web pages where file size matters.
- Does it strip EXIF data?
- Yes. The Canvas API does not preserve EXIF metadata. This is a privacy benefit — location data and camera info are removed.
- Can I convert WebP to JPG?
- Yes. Drop any WebP file and select JPG as the output format. Transparency in WebP will be replaced with a white background.
- How many files at once?
- Up to 20 images, max 20MB each. Three convert concurrently.
