Which conversions are supported?
The tool accepts JPG/JPEG, PNG and WebP and converts them to a different one of those three formats when your browser provides the selected decoder and encoder.
Image Converter
Convert one JPG, PNG or WebP image while preserving its pixel dimensions, with local previews, lossy quality controls and private downloads.

What this tool does
Image Converter changes one JPG, PNG or WebP image into a different supported format using your browser's built-in canvas and image encoders.
How to use it
- Upload one supported image and review its format, dimensions and file size.
- Choose JPG, PNG or WebP output, then adjust lossy quality or the JPEG background colour where relevant.
- Convert the image, compare the local preview and measured output size, then download the generated file.
Example input and output
Input: A 1600 × 900 pixel PNG image
Output: A locally generated 1600 × 900 pixel WebP image
Common use cases
- Converting PNG graphics to WebP for a website
- Creating a JPG copy of a transparent image with a chosen background
- Changing a photo to PNG for a format-specific workflow
FAQ
Will conversion change the image dimensions?
No. The converter keeps the browser-decoded width and height. Use Image Resizer when you need different pixel dimensions.
What happens to transparency in JPG output?
JPEG does not support transparency. Transparent pixels are filled with the JPEG background colour you select; the default is white. PNG and WebP output can retain transparency.
How does quality work?
The selected 40% to 100% quality value is passed to the browser for JPG and WebP output. PNG output does not use a lossy quality value, and conversion is not guaranteed to reduce file size.
Is my image uploaded?
No. File validation, decoding, conversion, previews and downloads happen locally in your browser without an image-processing API.
Are metadata and animation preserved?
No guarantee is made for metadata such as EXIF fields because canvas conversion can remove it. Animated GIF and animated WebP workflows are outside this static-image converter's supported input contract.
What are the limits?
The converter accepts one image up to 10 MiB, 8,192 pixels per side and 16 megapixels. These limits bound browser memory and processing work.
