Supported Formats

JPEG / JPG

The most widely used image format for photographs and complex images. Offers adjustable compression quality for the perfect balance between file size and visual quality. Ideal for social media posts, blog images, and email attachments.

PNG

Lossless compression format that preserves full image quality and supports transparency. Best for logos, icons, screenshots, and graphics with text or sharp edges where quality is paramount.

WebP

Modern format developed by Google offering superior compression. Produces files 25-35% smaller than JPEG at equivalent quality. Supports both lossy and lossless compression with transparency. Ideal for web optimization.

ICO

Icon format used for website favicons and Windows application icons. Our converter generates properly sized ICO files from any source image, perfect for branding your website or application.

Frequently Asked Questions

Is my image data sent to a server?

No. All image conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy.

How many images can I convert at once?

You can process up to 100 images in a single batch. All images are converted simultaneously and can be downloaded individually or as a ZIP file.

What social media presets are available?

We offer presets for Instagram (Square, Portrait, Story), YouTube (Thumbnail, Channel Art), Twitter (Header, Post), LinkedIn, and Open Graph images. Each preset uses the platform's recommended dimensions.

Does the converter maintain image quality?

Yes. You can adjust the quality slider from 0 to 100. The default is 90%, which offers an excellent balance of quality and file size. PNG output is always lossless regardless of the quality setting.

Can I convert images with transparency?

Yes. PNG and WebP formats preserve transparency. When converting to JPEG, transparent areas are automatically filled with a white background since JPEG does not support transparency.
