Frequently Asked Questions
How does client-side image conversion work?
Your browser uses native HTML5 Canvas, OffscreenCanvas, and hardware-accelerated codecs to decode image bitmaps and encode them into the target format entirely in memory. No network uploads occur.
Are these conversion tools completely free?
Yes, 100% free with no account registration, no file count restrictions, and no watermarks.
What is the maximum file size I can convert?
Each image can be up to 50 MB, which is ample for high-resolution mobile camera photos and DSLR captures.
Which format should I choose for the web?
For modern websites, WebP provides the best balance of small file sizes, high visual quality, and alpha transparency. For document submissions and printing, PDF is the standard choice.
