Image Converter — JPEG, PNG, WebP

The Image Converter from SarkariTool lets you change image formats instantly without installing any software. Whether you need to convert a PNG screenshot to JPEG for email, or a camera photo to WebP for your website — this tool does it in seconds, right in your browser.

Supported Conversions

  • PNG → JPEG — Reduce file size for photos and remove transparency
  • JPEG → PNG — Get lossless quality for screenshots and graphics
  • Any → WebP — Achieve the best compression-to-quality ratio for web use
  • BMP/GIF → JPEG/PNG/WebP — Convert legacy formats to modern standards

Before & After Comparison

After conversion, the tool displays a side-by-side comparison of the original and converted file sizes and formats, so you can see exactly how much space you've saved.

Quality Control

For JPEG and WebP formats, adjust the quality slider to find the perfect balance between file size and image quality. For PNG (which is lossless), the slider is automatically hidden since it has no effect.

Frequently Asked Questions

What image formats can I convert between?
You can convert any image (JPEG, PNG, WebP, BMP, GIF) to JPEG, PNG, or WebP output formats. The tool handles format detection automatically.

What is the difference between JPEG, PNG, and WebP?
JPEG is best for photographs — it uses lossy compression for small file sizes. PNG is ideal for images with transparency or sharp edges — it is lossless. WebP is a modern format that offers both lossy and lossless compression with smaller file sizes than JPEG and PNG.

How does the quality slider work?
For lossy formats (JPEG and WebP), the quality slider controls the compression level from 10% (smallest file, most compression) to 100% (best quality, largest file). For PNG, which is lossless, the slider has no effect.

Will converting PNG to JPEG remove transparency?
Yes. JPEG does not support transparency. When converting a PNG with transparent areas to JPEG, the tool automatically fills transparent areas with a white background.

How large of a file can I upload?
The maximum upload size is 50 MB. Most images, including high-resolution camera photos and scanned documents, are well within this limit.

Is my image uploaded to a server?
No. The entire conversion process happens in your web browser using the HTML5 Canvas API. Your image never leaves your device, ensuring complete privacy.

Why would I want to convert images to WebP?
WebP typically produces files 25–35% smaller than JPEG at the same visual quality, making it ideal for websites and apps. All major browsers now support WebP, and Google recommends it for website performance.
