PNG vs JPG vs WebP — which should you use?
JPG is best for photos and anything an upload form expects — small files, universal support. PNG keeps perfect quality and transparency, ideal for logos, screenshots and graphics. WebP is the modern web format — smaller than both at similar quality, great for websites.
How the converter works
Your image is decoded and re-encoded directly in your browser — no upload, no queue, no watermark. Transparent areas become white when converting to JPG, since JPG doesn't support transparency.
Converting HEIC from an iPhone?
Browsers can't open HEIC directly. On your iPhone, share the photo and choose "Convert to JPEG", or change camera settings to "Most Compatible" — then use this tool for any further conversion.
