Free Image Converter & Compressor — How It Works

Our Image Converter & Compressor makes it effortless to change image formats and reduce file sizes right in your browser. Whether you are a web developer optimizing assets for faster page loads, a designer preparing files for clients, or just someone who wants to convert a WebP photo into a more universally supported JPG, this tool handles it all with zero effort.

Unlike server-based converters, everything happens locally using the HTML5 Canvas API. When you upload an image, it is drawn onto an off-screen canvas element and re-encoded at your chosen format and quality level — your original file is never transmitted to any server. This approach delivers instant results and absolute privacy.

How to Convert an Image — Step by Step

Upload Your Image: Drag and drop a JPG, PNG, WebP, or GIF file into the upload zone, or click to browse your device.
Choose Output Format: Select JPEG for the smallest file sizes (ideal for photographs), PNG for lossless quality with transparency support, or WebP for the best combination of quality and compression for modern websites.
Adjust Quality: Use the Quality slider (1–100%) to find the perfect balance between image clarity and file size. The live preview updates instantly so you can see the result before downloading.
Download: Click the green "Download Image" button. Your converted file is saved directly to your device — no sign-up required.

Frequently Asked Questions

What is the difference between JPEG, PNG, and WebP?

JPEG uses lossy compression, making it ideal for photographs where a slightly lower quality is acceptable in exchange for small file sizes. PNG uses lossless compression and supports transparency, making it perfect for logos and graphics. WebP is a modern format developed by Google that offers superior compression for both lossy and lossless images, resulting in smaller file sizes than JPEG or PNG with equivalent visual quality.

Will converting change my image dimensions?

No. This tool only changes the image format and compression level. Your image dimensions (width and height in pixels) are preserved exactly. If you need to resize the image, use our separate Image Resizer tool.

Is there a file size limit for images I can convert?

There is no server-side file size limit because your image is processed locally in your browser. Very large images (e.g., over 50MP RAW files) may be slow to process depending on your device's hardware capabilities.
