What is an image format converter?
An image format converter creates a copy of a picture in a different file type. This tool converts between JPG, PNG and WebP while keeping the image's pixel dimensions. It can help when a website only accepts one format, when you need transparency, or when you want a more web-efficient copy of an image.
Upload a supported image, select the format you need and convert it directly in your browser. For JPG and WebP output, you can choose a quality level. The tool makes a separate downloadable file and does not alter the original image on your device.
How to convert an image
- Add a JPG, PNG or WebP file.
- Choose JPG, PNG or WebP as the target format.
- Adjust quality when creating JPG or WebP output.
- Pick a background color for JPG if the source has transparency.
- Convert the image, review the preview and download the new file.
JPG is a widely supported choice for photographs. PNG is useful for screenshots, logos and graphics that need sharp edges or transparent areas. WebP is a modern format that can combine efficient compression with transparency, making it a practical web option when your destination supports it.
Transparency and JPG
PNG and WebP can preserve transparent pixels, but JPG cannot. When you convert a transparent image to JPG, the converter paints those areas with the background color you choose. White is a safe default for documents and product photos, while a matching brand or page color can help the image blend into a layout.
Why convert locally?
Browser-based conversion avoids uploading personal images to a remote service. That can be useful for document scans, receipts, private photos and client assets. It also removes upload waiting time: Canvas draws the source image and encodes the chosen format on your device. Converting does not improve an already low-resolution image, and repeatedly converting a lossy JPG or WebP can reduce detail. Keep your original file, then use the converted copy only where its new format is needed.
