Is PNG or JPG better quality?

PNG is technically higher quality because it uses lossless compression — every pixel is stored exactly. JPG uses lossy compression, which discards some data. However, at high quality settings (85%+) the difference is invisible in most images, especially photographs.

Is PNG or JPG smaller in file size?

JPG is almost always smaller in file size, especially for photographs. A typical photo as JPG at 90% quality might be 5–10x smaller than the same image as PNG. For simple graphics with flat colours, PNG can sometimes be smaller due to its different compression algorithm.

Which format should I use for a website?

Use JPG for photographs and hero images. Use PNG for logos, icons, and graphics with transparency. For the best performance, consider converting both to WebP with PNG and JPG fallbacks for older browsers.

Does PNG support transparent backgrounds?

Yes. PNG supports full transparency (alpha channel) and partial transparency. This makes it ideal for logos, icons, and graphics that need to sit on different backgrounds. JPG does not support transparency at all.

Which format is better for printing?

For printing, PNG or high-quality JPG (95%+) are both acceptable. PNG is preferable for graphics with text or sharp edges. For photographs destined for print, use the original RAW or high-resolution TIFF if available, or JPG at maximum quality.

Can I convert between PNG and JPG without quality loss?

Converting JPG to PNG is lossless — the PNG perfectly stores the JPG data. Converting PNG to JPG involves some quality loss because JPG is lossy, but at 90%+ quality it is usually imperceptible. Use FixTools to convert between formats with quality control.

What is the difference between PNG and PNG-8?

Standard PNG (PNG-24) supports millions of colours and full transparency. PNG-8 is a limited variant that only supports 256 colours and simple (on/off) transparency — similar to GIF. For modern use, standard PNG-24 is almost always the right choice.

How It Works

Step-by-step guide to png vs jpg: which format should you use?:

1
Use PNG for graphics, logos, and screenshots
Choose PNG when your image has a transparent background, contains text, icons, or sharp-edged graphics, or when you need pixel-perfect lossless quality. PNG is also ideal for images you plan to edit further.
2
Use JPG for photographs and social media
Choose JPG for photographs, product images, and any image where slight quality reduction is acceptable in exchange for much smaller file size. JPG is the standard for social media, email, and web photography.
3
Use PNG for images with transparency
If your image needs a transparent or semi-transparent background (logos, UI elements, watermarks), PNG is required — JPG cannot store transparency.
4
Consider WebP as a modern alternative
WebP offers the best of both worlds: smaller file sizes than JPG with support for transparency like PNG. It is widely supported in modern browsers and is increasingly the recommended format for web images.
5
Convert between formats when needed
Use the FixTools Image Format Converter to switch between PNG and JPG (and other formats) instantly when your needs change.
