JPG vs PNG

JPG uses lossy compression designed for photographs. It makes realistic images small, but it cannot store transparency, and sharp edges like text and lines can pick up faint smudges.

PNG is lossless and supports transparency. It is ideal for logos, icons, screenshots and diagrams, but photos saved as PNG are often five to ten times larger than the same photo as JPG.

PNG vs WebP

WebP can work in two ways: lossy, like JPG, or lossless, like PNG, and it supports transparency in both. For graphics with transparent backgrounds on a website, a lossy WebP is usually much smaller than a PNG while looking the same. Keep PNG when you need pixel-exact copies or maximum compatibility with older software.

When to use WebP

Use WebP for images on websites and in web apps. Every current browser supports it, and it typically produces smaller files than JPG at similar quality, which makes pages load faster. Avoid it when sending images to people or systems that may not open it: some older desktop software, printing services and upload forms still expect JPG or PNG.

Frequently asked questions

Why is my converted PNG larger than the JPG?

PNG is lossless, so it stores every pixel of the decoded photo exactly, including the noise that JPG compression would discard. Photos converted to PNG are almost always larger. Use PNG when you need lossless editing or transparency, not to save space.

Does converting JPG to PNG improve quality?

No. Converting cannot restore detail that JPG compression already removed. It only prevents further loss if you edit and re-save the image later.

What happens to transparent backgrounds when converting to JPG?

JPG cannot store transparency, so transparent areas are filled with a solid colour. It is white by default, and you can pick any other colour in the settings.

Can I convert HEIC, GIF or AVIF images?

Not yet. Vexluno currently reads JPG, PNG and WebP. On iPhone, photos shared or exported as "Most Compatible" are saved as JPG.
