Image Converter
PNG, JPEG, and WebP conversion in your browser — with straight talk about transparency and compatibility. Never uploaded.
How to use this tool
- Choose an image in any format your browser can display (PNG, JPEG, WebP, GIF, BMP — HEIC on Safari).
- Pick the output format; set quality for the lossy ones.
- Download the converted copy. The original stays untouched on your device.
How it works
Your browser decodes the image, and the canvas re-encodes it in the target format — all locally. Format cheat sheet: PNG is lossless with transparency (best for graphics, screenshots, logos); JPEG is small and universal but lossy with no transparency (photos going anywhere); WebP does both jobs 20–30% smaller but very old software may not open it.
Transparency note: converting transparent PNG/WebP to JPEG fills the transparent areas with white, because JPEG has no alpha channel. Animated GIFs convert as their first frame only.
Frequently asked questions
Can this convert HEIC iPhone photos?
Only where the browser itself can decode HEIC — Safari on Apple devices generally can; Chrome and Firefox generally can't. If the file loads in the preview, the conversion will work.
Which format should I pick?
Photos for sharing: JPEG. Graphics, screenshots, anything needing transparency: PNG. Web images where you control the audience: WebP for the size savings.
What happens to transparency when converting to JPEG?
JPEG can't store it, so transparent regions become white. Convert to PNG or WebP instead if you need the transparency preserved.
