Image Format Converter

Convert image formats locally in your browser with preview, quality controls, file-size summary, and download.

Image input

Choose a PNG, JPEG, WebP, GIF, or SVG file from your device.

Processed locally in your browser Limit local image files. Your input is processed in your browser and is not uploaded or sent to a server. Avoid pasting production secrets, access tokens, private keys, passwords, or sensitive customer data unless you understand the risk.

Conversion options

Output format
The converter adds the matching extension when you download.

Converted preview

Convert an image to preview the exported result.

Preview appears after conversion.

Original preview, converted preview, file-size comparison, metadata notes, and download actions stay in this browser session.
Images are processed locally with FileReader, Image, Blob, and canvas APIs.

Image format conversion guide

Convert images for websites, apps, documentation, favicons, previews, and sharing while choosing the right tradeoff between compatibility, transparency, and file size.

PNG, JPEG, WebP, and AVIF

PNG is best for crisp graphics and transparency. JPEG is broadly compatible for photos. WebP and AVIF can be smaller when browser export support is available.

Transparency handling

PNG and WebP can preserve transparent pixels. JPEG cannot, so transparent input is flattened onto the selected background color during export.

Quality settings

JPEG, WebP, and AVIF use quality settings to balance visible detail and file size. Lower values shrink files faster but can introduce artifacts.

GIF and SVG input

GIF files are rasterized as a still canvas frame, so animation may not survive conversion. SVG files are rasterized through browser image loading, and external references may not be included.

Metadata limitations

Canvas export may strip EXIF, camera, GPS, orientation, color-profile, and other metadata. Keep the original file if metadata preservation matters.

Browser-local processing

The selected file is decoded and exported in your browser. This page does not upload images, fetch remote image URLs, or call a conversion API.

Frequently asked questions

Does Image Format Converter upload my image?

No. The selected image is read and exported locally in the browser with image and canvas APIs.

Which input formats are supported?

The tool accepts browser-readable PNG, JPEG, WebP, GIF, and SVG files. Some browser or device limits can still prevent very large or unusual files from decoding.

Why is WebP or AVIF disabled?

Canvas export support varies by browser. WebP and AVIF appear only when the current browser reports that it can export that format.

Will GIF animation be preserved?

No. GIF input is converted through canvas as a still raster image, so animation is not preserved in the downloaded output.

What happens to transparent pixels in JPEG output?

JPEG does not support alpha transparency. Transparent areas are composited against the selected background color before export.

Will EXIF metadata and color profiles stay intact?

Usually not. Browser canvas export can strip EXIF, orientation tags, GPS data, embedded color-profile details, and other metadata.
