  • JPG and JPEG

  • PNG

  • WebP

  • SVG

You can convert them into:

  • PNG

  • JPG or JPEG

  • WebP

Which Image Format Should You Choose?

PNG

Choose PNG when you need transparency, sharp text, logos, screenshots, or graphics with clean edges. PNG files preserve image quality but can be larger than JPG or WebP files.

JPG

JPG is suitable for photographs, product images, blog posts, and other images where a smaller file size is more important than transparency. Transparent areas are replaced with the selected background colour when converting to JPG.

WebP

WebP offers a good balance between image quality and file size. It is an excellent option for websites because it can help pages load faster while maintaining clear visual quality.

Private Browser-Based Conversion

Unlike converters that upload images to a remote server, this tool processes your files inside your browser. Your selected images remain on your device throughout the conversion process.

This makes the converter suitable for personal photographs, client assets, design files, screenshots, and other images you may not want to upload to an external service.

Convert Images for Websites and Everyday Use

Use the converter to prepare images for websites, online stores, social media posts, presentations, documents, or email attachments. Developers and designers can also use it to quickly create browser-friendly versions of image assets without opening desktop editing software.

For example, you can convert a large PNG photograph to WebP for better website performance, turn a WebP image into PNG for easier editing, or convert a transparent design to JPG with a background colour.

Frequently Asked Questions

No. Image conversion takes place locally in your browser. Your files are not uploaded to or stored on the DevToolbox server.

Yes. You can use the tool for free without creating an account.

Yes. SVG files can be converted into PNG, JPG, or WebP images. Because these output formats are raster-based, the downloaded image will use the dimensions defined in the original SVG file.

Choose PNG or WebP if you need to preserve transparent areas. JPG does not support transparency, so transparent areas will use the selected background colour.

It depends on the selected format. JPG and WebP can use lossy compression, which may slightly reduce image quality in exchange for a smaller file. PNG uses lossless compression and is better suited to graphics, text, and transparency.

No. The converter works entirely inside a modern web browser and does not require additional software or browser extensions.
