About Image Format Converter (PNG, JPG, WebP)
Load an image and pick a target format to convert between PNG, JPG, and WebP. For the lossy formats you can move a quality slider to trade file size against visual detail before downloading the result.
Conversion runs in your browser on a canvas, so your image stays on your device with nothing uploaded. Switching a photo to WebP or JPG is a common way to cut page weight, while PNG is the right pick when you need lossless quality or transparency.
Frequently asked questions
- Which format gives the smallest file?
- WebP usually produces the smallest files for both photos and graphics, with JPG a close second for photographic images.
- Why did transparency disappear after converting to JPG?
- JPG does not support an alpha channel, so transparent areas are flattened onto a solid background.
- Does converting PNG to PNG change anything?
- Re-encoding a PNG is lossless, so the pixels stay identical even though the file may differ slightly in size.
