Choosing the output format
JPG is the default for photographs and the safest bet when you need broad compatibility. It compresses lossily, so files stay small and repeated saves soften detail.
PNG stores pixels losslessly and supports transparency. Use it for screenshots, line art, and logos, or when a destination system specifically asks for PNG.
WebP is the modern web format: usually smaller than JPG at similar quality, with transparency support. Use it for site assets when your browsers and CMS accept it.
The six conversions that cover everyday cases
JPG to PNG, JPG to WebP, PNG to JPG, PNG to WebP, WebP to JPG, and WebP to PNG. Those six pairs handle almost every request. JPG and JPEG are the same format, so a file named .jpeg works anywhere a .jpg is accepted.
Each converter takes one image up to 25 MB and produces the new file in your browser. Animated WebP files are not supported; static WebP only.
Each pair also has its own page if you already know what you need, which skips the format picker. The shared tool exists for the common case of having a file and only knowing that something in the pipeline wants a different extension.
Steps to pick a new format
The conversion is performed locally on your device. No file is uploaded to a server, and there is no account or watermark.
Watch the size column after conversion. JPEG and WebP usually shrink photos, while PNG usually grows them. Knowing the direction of the change saves you from swapping one problem for another.
- Open the convert image tool.
- Select the JPEG, PNG, or static WebP file you want to change.
- Choose the output format.
- Generate the new file and check its size and dimensions.
- Download the converted image.
What conversion cannot do
Changing the file type does not add transparency that never existed, restore detail a lossy format already discarded, or crop, rotate, or watermark the image. Those tools are not part of the site.
If you need a PDF made from images, or pages turned back into images, those live with the PDF tools rather than the image converter.
- Converter inputs: HEIC, GIF, BMP, TIFF, SVG, and AVIF are not accepted.
- PDF files are handled by the PDF tools, such as PDF to JPG or PDF to PNG, not by the image converter.
- Batch conversion is not supported; process files one at a time.
After you convert
If the new file is still too large for a form or upload, compress it to a KB target. If the dimensions are wrong for a layout, resize with the aspect ratio locked. Conversion, compression, and resizing solve different problems; combine them in the order that fits your goal.
