Convert Image Format Between JPG, PNG and WebP
Nujiz Image Convert re-encodes an image into the output format you select directly in your browser. The source is drawn to Canvas and exported in the new format while keeping the original pixel dimensions.
Image formats have different properties. PNG is useful when transparency is required, while JPEG has no alpha channel. When JPEG is selected, the tool paints a white background first so transparent pixels do not become an unwanted dark background.
How to Use This Tool
- Choose the image you want to convert.
- Select an available output format.
- Start the conversion.
- Review the result, especially transparency when converting to JPEG.
- Download the image in its new format.
Important Notes for Better Results
Format conversion does not increase image resolution, restore missing detail, crop the image or change its dimensions. Keep the source file if you may need to create other formats later.
Frequently Asked Questions
Does format conversion change image dimensions?
No. The image is re-encoded while retaining its original pixel dimensions.
What happens to transparency when converting to JPEG?
JPEG does not support transparency, so the tool places a white background behind transparent areas.
Does converting an image improve its quality?
No. Conversion changes the file format and does not create additional image detail.
Can I convert an image to PNG?
Yes, when PNG is selected from the available output formats.
Is conversion performed in the browser?
Yes. The image is redrawn and encoded locally in your browser.
