Frequently Asked Questions
- Is this image format converter free?
- Yes, completely free with no limits. You can convert as many images as you want without creating an account or paying anything.
- Are my images uploaded to a server?
- No. All conversion happens directly in your browser using the HTML5 Canvas API. Your images never leave your device, so your files are completely private.
- What image formats are supported as input?
- You can upload JPEG, PNG, WebP, GIF, and BMP images. The output format can be JPEG, PNG, or WebP.
- Why is the PNG quality slider disabled?
- PNG is a lossless format — every pixel is stored exactly. There is no quality to reduce, so the slider does not apply to PNG output. For smaller files with photos, use JPEG or WebP instead.
- Why is WebP better for websites?
- WebP provides 25–35% smaller file sizes compared to JPEG at the same visual quality. Smaller images mean faster page loads, better Core Web Vitals scores, and lower bandwidth usage — all important for SEO and user experience.
- Does converting JPEG to PNG make the image lossless?
- Converting JPEG to PNG stops any further quality loss, but it cannot recover detail already lost during the original JPEG compression. The PNG will be lossless from that point forward, but the existing JPEG artifacts remain.
