Image Converter
Convert images between JPEG, PNG, WebP, BMP, and ICO formats online. Adjust quality, set background color for transparency, and batch process multiple files. Free, private, no upload required.
What image formats does this converter support?
This tool supports converting between JPEG, PNG, WebP, BMP, and ICO formats. You can convert from any supported format to any other. WebP availability depends on your browser's support.
How do I convert JPG to PNG?
Upload your JPG file, select PNG as the output format, and click convert. The tool will process the image in your browser and provide a download link instantly.
Why do I need to set a background color?
When converting from a format that supports transparency (like PNG or WebP) to one that doesn't (like JPEG or BMP), transparent areas must be filled with a solid color. You can pick any background color you prefer.
What quality setting should I use for JPEG and WebP?
A quality setting of 85 offers a great balance between image quality and file size. Use 90–100 for maximum quality, or 60–75 for smaller files with acceptable quality loss.
Can I convert multiple images at once?
Yes! You can upload and convert multiple images simultaneously. After conversion, use the "Download All" button to save all converted images at once.
Are my images uploaded to a server?
No. All image processing happens entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy.
Is this tool free to use?
Yes, this image converter is completely free with no limits on the number of conversions. There are no watermarks, no registration required, and no hidden fees.
What is the difference between JPEG, PNG, and WebP?
JPEG is best for photographs with smaller file sizes. PNG supports transparency and is ideal for graphics and logos. WebP offers superior compression for both photos and transparent images, but may not be supported everywhere.
Can I convert an image to ICO for use as a favicon?
Yes! You can convert any image to ICO format, which is commonly used for website favicons. The tool will resize and convert the image appropriately.
Does this tool work on mobile devices?
Yes, the converter works on any modern browser including smartphones and tablets. The interface is fully responsive and optimized for touch screens.
What is the maximum file size I can convert?
Since processing happens in your browser, the limit depends on your device's available memory. Most images up to 20–30 MB can be converted without issues.
Can I adjust the image dimensions during conversion?
This tool focuses on format conversion. If you need to resize images, you can use a dedicated image resizer tool before or after conversion.
How to Use Image Converter
Convert images between JPEG, PNG, WebP, BMP, and ICO entirely in your browser. Set the output quality, replace transparency with a background color, and batch-process multiple files — nothing is ever uploaded.
- Add one or more images to the queue — batch mode converts them all in a single pass.
- Pick the target format: JPEG, PNG, WebP, BMP, or ICO.
- Adjust the quality level for lossy formats to balance file size against image clarity.
- Choose a background color so transparent areas become solid when converting to a format without alpha support.
- Convert the files and download each result, or save all converted images together.
When generating an ICO icon, start from a square image so it renders cleanly at the small favicon sizes.
