PNG vs JPG
PNG and JPG are the two most common image formats. They solve different problems: one stores images losslessly and supports transparency, the other produces much smaller files. Here is how to choose.

The key difference
JPG uses lossy compression: some detail is discarded when you save, but the file stays small. PNG uses lossless compression and supports transparency, so files are usually larger.
In short: JPG is for photos and the web, PNG is for graphics, screenshots, logos and images with a transparent background.
Which one to choose
Photos and the web: JPG or WebP. JPG is universal; WebP is more efficient but not supported by every older app.
Screenshots, diagrams and logos: PNG. It keeps sharp edges, text and transparency without compression artefacts.
Print: photos are often saved as high-quality JPG or TIFF, graphics as PNG or TIFF. Web formats are redundant for print.
Repeated editing: PNG. Re-saving a JPG can degrade quality, while PNG keeps the image lossless.
Size and quality
JPG wins on size, but sharp edges and small text can show halos and noise. PNG wins on accuracy but takes more space. WebP is a compromise: often smaller than JPG at similar quality, with transparency support.
If you need the most compatible file, choose JPG. If accuracy and transparency matter, choose PNG. For a modern website, consider WebP as well.
How to convert
Our JPG to PNG and PNG to JPG converters run directly in your browser: the image is not uploaded to the server. For the web, you can also convert the file to WebP.
Questions and answers
Which is better for photos: PNG or JPG?
JPG is usually better for ordinary photos: the file is smaller and the quality difference is hard to see. PNG is useful when you need to edit the image repeatedly without losses.
Why is PNG larger than JPG?
PNG stores image data losslessly, so there is more data. JPG compresses more aggressively and saves space, but it can introduce artefacts.
Does JPG support transparency?
No. PNG and WebP support transparency. When you convert PNG to JPG, transparent areas become white.
Which format should I use on a website?
WebP or JPG is often used for photos, while PNG or WebP is used for logos and graphics with transparency. The right choice depends on the design and page-weight budget.
