Convert Image

How to convert an image format

1. Drop your image or click to choose a file.
2. Select the target format, choose from JPEG, PNG, or WebP.
3. The converted image is generated in your browser instantly.
4. Download the converted file. No account needed.

Common uses

• Converting PNG screenshots to JPEG to reduce file size, then compress further for maximum savings
• Converting images to WebP for better web performance
• Changing JPEG photos to PNG to preserve transparency when editing, use image crop to trim the result to the right dimensions

Technical specification

• Algorithm or formula: Source image is decoded by the browser, drawn to an off-screen canvas, then re-encoded with canvas.toBlob at the chosen MIME type. JPEG accepts a quality parameter (0 to 1).
• Browser API or library: Canvas 2D API. No external library.
• Input limits: Files up to 50 MB and 50 megapixels.
• Output: JPEG (.jpg), PNG (.png), or WebP (.webp) blob downloaded directly.
• Known limitations: Single-image only (no batch conversion). EXIF metadata is dropped in re-encoding. Converting from a lossy source to a lossless format does not recover quality.

Frequently asked questions

What formats can I convert between?

The tool supports conversion between JPEG, PNG, and WebP, the three most common web image formats.

Will I lose quality when converting?

Converting between lossless formats is quality-neutral. Converting to JPEG introduces some compression; use the quality slider to control this.

Is my image uploaded to a server?

No. All conversion happens in your browser using the Canvas API.

Can I convert multiple images at once?

The tool processes one image at a time. Convert files one after another for batch use.
