Frequently Asked Questions

Which image formats are supported?
This tool accepts JPG, PNG, WebP, AVIF, BMP, and GIF as input. You can convert to JPG, PNG, WebP, or BMP output format.
Can I convert multiple images at once?
Yes, you can upload up to 10 images and convert them all at once with the same settings. Each file is processed individually in your browser.
Does the quality slider affect PNG output?
No. PNG is a lossless format, so the quality slider only affects JPG and WebP output. PNG files will always preserve full quality.
Can I resize images during conversion?
Yes. Enable the resize option and specify width, height, or both. If you only specify one dimension, the other is calculated automatically to preserve the aspect ratio.
Are my images uploaded anywhere?
No. All conversion happens in your browser using the Canvas API. Your images stay on your device at all times.
