Choose the format before you convert
PNG suits graphics, screenshots and images that need transparency. JPG is a practical choice for photographs and broad compatibility, but it cannot store transparent pixels. WebP works well for modern websites and supports both photographic images and transparency.
Step-by-step
- Open the Format Converter and choose the source image.
- Select PNG when transparent areas or crisp graphic edges matter.
- Select JPG for a photograph that needs wide compatibility; choose the color that should replace transparent areas.
- Select WebP for a modern web asset or a smaller photographic export.
- Adjust quality for JPG or WebP. Check text, gradients and fine detail in the preview.
- Apply any required rotation, convert the image and download the new file.
What conversion does not do
Changing a small JPG into PNG does not restore detail removed by earlier encoding. Likewise, renaming a file extension is not a real conversion; the pixels must be decoded and exported into the new format.
Quick choice
- Need transparency?: Choose PNG or WebP.
- Sending a photo broadly?: Choose JPG.
- Preparing a modern web asset?: Choose WebP, then verify it in your target workflow.
