Image Converter — Change Image Format Without Losing Quality

Different situations call for different image formats. A logo needs to be PNG for transparency support. A photograph going on a website should be JPEG for smaller file size. A modern web application might want WebP for better compression. An icon set might need ICO format. Converting between image formats is a routine task, but it shouldn't require opening image editing software every time. This tool converts between the major image formats directly in your browser.

Upload an image in one format, select the format you want, and download the converted file. The conversion runs locally — your image doesn't leave your device. No account, no size limits beyond what your browser can handle, no watermarks on the output.

When to Use Each Format

JPEG is the right choice for photographs and images with complex colour gradients. It compresses very efficiently — a 5MB photo from your camera can become a 300–500KB JPEG that's nearly indistinguishable at screen viewing sizes. The trade-off is that JPEG compression is lossy and each save reduces quality slightly. JPEG doesn't support transparency.

PNG is the right choice when you need transparency (logos, icons, overlays, anything that needs to be placed on a variable background) or when you need lossless quality preservation (screenshots of text, UI mockups, anything with sharp edges and flat colours). PNGs are larger than JPEGs for photographic content but are lossless.

WebP is a modern format from Google that achieves better compression than JPEG while supporting transparency like PNG. Supported by all modern browsers, it's increasingly the preferred format for web images. If you're optimising images for a website and your platform supports WebP, it's worth converting.

GIF supports animation and transparency but is limited to 256 colours, making it suitable only for simple illustrations, logos, and animations — not photographs. Converting a photo to GIF will reduce its colour fidelity significantly.

BMP is an uncompressed format used in some Windows applications. It's rarely needed for web work but occasionally required by specific software or older systems.

Common Use Cases

Removing white backgrounds from logos: If you have a logo as a JPEG (which can't have transparency), convert it to PNG. Then use the background removal tool to make the background transparent. The resulting PNG logo can be placed on any coloured surface without a white box around it.

Optimising images for websites: Upload images from your camera or stock photo site as high-quality JPEGs, convert to WebP for better web performance, and use the Image Compressor to fine-tune the file size before uploading to your site.

Preparing images for specific platforms: Some forms and portals only accept specific formats. Government portals, university applications, and other official platforms sometimes specify exactly which format they accept. Convert to match the requirement.

Converting screenshots for editing: Screenshots are often saved as PNG. If you need a smaller file for sharing or a format that plays better with a particular software, convert to JPEG.

Making animated GIFs editable: Convert individual frames from an animation into standard image files for editing, then reassemble. Or convert a static image to GIF as part of a workflow for creating simple animations.

Tips

Converting from a lossy format (JPEG) to a lossless format (PNG) doesn't recover quality that JPEG compression already removed — it just prevents further quality loss. If your original JPEG is already heavily compressed, the PNG you get will be large but won't look better than the original JPEG.

Converting from PNG or another lossless format to JPEG will reduce file size significantly but introduces lossy compression. Use a quality setting of 85–90% for most photos to keep the file small without visible quality loss. Use 95%+ if quality is critical.

Limitations

Animated GIF-to-video conversion isn't supported — this tool handles static image format conversion. Very large images (above 30–40MP) may be slow to convert in the browser. HEIC/HEIF format (the default iPhone photo format) may not be supported in all browsers — convert these using your phone's built-in export or a dedicated converter first.
