What is an image format converter?
An image converter changes a picture from one file format into another. Different formats are designed for different purposes. For example, JPG is commonly used for photographs, PNG is useful for graphics and transparency, and WebP is often chosen for web images.
Changing an image format can help make a file more suitable for a website, an online form, a presentation or a creative project. The right format depends on the image, the required quality and where you plan to use it.
How to convert an image with PixNexa
- Select an image from your device or drag it into the upload area.
- Choose WebP, JPG or PNG from the output format menu.
- Adjust the quality setting if needed.
- Optionally enter maximum width and height values.
- Click Process image and wait for the converted preview.
- Check the result and select Download image.
You can try different formats and settings to find the output that best fits your needs.
Understanding JPG, PNG and WebP
JPG (JPEG)
JPG is a widely supported image format commonly used for photographs and everyday pictures. It uses lossy compression, which means some image information may be discarded to reduce file size. JPG does not support transparent backgrounds.
Choose JPG when you need a familiar format for photographs, email attachments or platforms that specifically request JPEG files.
PNG
PNG supports lossless compression and transparency. It is often suitable for logos, icons, screenshots, diagrams and graphics with transparent areas. PNG photographs can be larger than equivalent JPG or WebP files.
Choose PNG when preserving sharp edges or transparency is important.
WebP
WebP supports both lossy and lossless compression, as well as transparency. It is designed for efficient image delivery on the web and can produce smaller files than some traditional formats, depending on the image and settings.
Choose WebP for website images when the platforms and browsers you use support it.
Which image format should you choose?
- For photographs: JPG or WebP can be suitable options.
- For transparent logos: PNG or WebP may be appropriate.
- For screenshots and diagrams: PNG can preserve crisp text and edges.
- For website images: WebP is worth considering for efficient delivery.
- For broad compatibility: JPG and PNG are widely supported.
Always check the converted result. Changing formats does not automatically guarantee a smaller file or better quality.
How does the quality setting work?
The quality control affects lossy output formats such as JPG and WebP. Higher settings generally preserve more visual detail but may create larger files. Lower settings can reduce file size but may introduce visible compression artifacts.
PNG uses a different compression approach, so changing the quality slider may not affect PNG output in the same way. For important images, compare the preview before downloading.
Resize images while converting
PixNexa also lets you set maximum width and height values. This can help when an image is much larger than the space where it will appear. For example, a large photograph may not need its original dimensions when used as a small article thumbnail.
Leave both fields empty if you want to keep the original dimensions. The tool does not enlarge images beyond their original size.
Browser-based image conversion
PixNexa uses browser features such as Canvas to process selected images locally on your device. The converter is designed not to upload selected images to a PixNexa processing server. Normal website hosting and analytics requests may still take place. See our Privacy Policy for more details.
Frequently asked questions
1. Is the PixNexa Image Converter free?
Yes. You can use the online converter without creating an account or installing desktop software.
2. Which image formats can I upload?
The tool accepts common image uploads including JPG, PNG, WebP, BMP and GIF, with a maximum file size of 25 MB. Support for individual formats may depend on your browser.
3. Which formats can I download?
You can select WebP, JPG or PNG as the output format.
4. Does converting an image reduce its quality?
It depends on the output format and quality setting. Converting to a lossy format such as JPG or lossy WebP may discard some image detail. PNG output uses a different compression method.
5. Can I convert PNG to JPG?
Yes. Upload your PNG image, select JPG as the output format and process it. Remember that JPG does not support transparency, so transparent areas cannot remain transparent in the JPG output.
6. Can I convert JPG to PNG?
Yes. Select PNG as the output format. However, converting a JPG to PNG does not restore image detail that may already have been lost through JPG compression.
7. Will WebP always be smaller than JPG?
No. File size depends on the original image, dimensions, quality and encoding. Compare the output files to see which format works best for your image.
8. Are animated GIFs preserved?
No. Animated GIF uploads are processed as a still frame. The original animation is not preserved.
