What image formats can I convert between?

We support conversion between major raster formats including JPG, PNG, WebP, GIF, and BMP. You can also generate SVG vector previews.

Are my images uploaded to any remote server?

No. All conversion operations run locally on your device inside your browser memory. Your personal or business images are never transmitted or saved to external servers.

Why should I convert images to WebP?

WebP provides superior lossless and lossy compression compared to JPEG and PNG, producing 25–35% smaller file sizes with indistinguishable visual quality. It is natively supported by all modern browsers and improves Google PageSpeed scores.

How many images can I convert at once?

You can select and batch convert up to 50 images in a single session with a combined file size limit of 100 MB.

Will converting images reduce their visual quality?

Converting to lossless PNG maintains 100% of pixel data. When converting to lossy formats like JPEG or WebP, you have full control over the quality slider to balance visual fidelity and file size.

Can I preserve image EXIF metadata during conversion?

Client-side canvas rendering strips camera and GPS metadata to minimize output file size and protect your privacy. Always keep your original source files if EXIF data is required.

Is this image conversion tool free?

Yes, it is completely free with no user accounts, watermarks, or usage limits.
