Convert image format in three steps
Convert PNG, JPG, and WebP images without uploading files or installing desktop software. Choose PNG when lossless graphics or transparency matters, JPG for broad compatibility and photographic content, or WebP for efficient modern web delivery. Quality presets apply to lossy JPG and WebP outputs, while PNG uses its lossless browser encoding.
The converter preserves source pixel dimensions and shows an immediate preview with the new file size. Format conversion is distinct from resizing: no pixels are added or removed. JPG cannot represent transparency, so use PNG or WebP when transparent backgrounds are required.
Decoding, canvas rendering, and output encoding run in a dedicated browser worker. Your source image stays on the device and the interface remains responsive. Converting an already compressed image does not restore lost detail, and repeated lossy conversions can reduce quality. Whenever possible, convert once from the highest-quality source and then use the final target format for subsequent work.

Frequently asked questions
Which format should I use?
PNG suits transparency and graphics, JPG suits photographs, and WebP often balances quality and size.
Is conversion local?
Yes. The image stays in your browser and is processed in a worker.
What happens to transparency in JPG?
JPG cannot store transparency, so transparent areas may become dark or use the browser encoder background.
Does conversion resize the image?
No. Pixel dimensions remain unchanged.
