Image Format Converter: frequently asked questions
How do I convert PNG to JPG?
Add the PNG, choose JPG as the output and pick a background colour, because JPG cannot store transparency. White suits most documents. Then select Convert and download.
How do I convert WebP to JPG?
Add the WebP image, choose JPG and select Convert. JPG opens in almost every app and website that refuses WebP. If you need transparency, choose PNG or use the one-step WebP to PNG converter.
How do I convert JPG to WebP?
Add the JPG, choose WebP, set the quality (80–85% is a good balance) and select Convert. WebP files are usually much smaller, which makes web pages load faster.
Which format should I use: JPG, PNG or WebP?
Use JPG for photos that must open everywhere, PNG for screenshots, logos and anything with transparency, and WebP for websites, where it gives the smallest files. To make a file smaller without changing format, use the Image Compressor.
Does converting an image reduce quality?
Converting to PNG keeps every pixel. Converting to JPG or WebP uses lossy compression, but at 85% quality the difference is hard to see. The result shows the real before and after file size.
Can I convert several images at once?
Yes. Add up to 50 images (200 MB in total). Each one is converted with the same settings and downloaded separately.
How do I convert JPG to PNG?
Choose PNG as the output here, or use the dedicated JPG to PNG converter. Note that a JPG’s background stays solid; changing the format does not make it transparent.
