Is WebP better than JPG?

For most web use, yes — WebP produces smaller files at the same quality and also supports transparency. JPG still wins on compatibility with very old software.

Does converting PNG to JPG lose quality?

Converting to JPG applies lossy compression, so there is some quality loss, but at high quality settings it is usually invisible. JPG also removes transparency, filling it with a background colour.

Which format is smallest?

WebP is typically the smallest at a given quality level, followed by JPG for photos. PNG is the largest for photographic content but lossless.

PNG vs JPG vs WebP: Which Image Format Should You Use?

PNG, JPG, and WebP are the three image formats you’ll meet most often on the web. They look similar in a folder, but choosing the right one can cut your file sizes dramatically without anyone noticing a difference in quality. Here’s how to pick.

The 30-second answer

Photographs → JPG (or WebP for smaller files).
Logos, icons, screenshots, anything with transparency → PNG (or WebP).
You want the smallest possible file and modern browser support → WebP.

JPG (JPEG): best for photos

JPG uses lossy compression: it throws away detail the human eye barely notices to make files small. That’s perfect for photographs, where millions of subtle colour gradients compress beautifully. The trade-off is that JPG doesn’t support transparency, and saving the same JPG repeatedly degrades it a little each time. For a photo headed to a website or email, JPG at around 80% quality is usually the sweet spot between size and looks.

PNG: best for graphics and transparency

PNG uses lossless compression — it reproduces every pixel exactly. That makes it ideal for logos, icons, line art, screenshots, and anything that needs a transparent background. The downside is size: a photo saved as PNG can be five to ten times larger than the same photo as JPG. Use PNG when sharp edges or transparency matter, not for full-colour photographs.

WebP: the modern all-rounder

WebP is Google’s newer format, and it supports both lossy and lossless modes plus transparency. In practice it produces files roughly 25–35% smaller than JPG or PNG at the same visual quality. Every modern browser supports it, so for new websites WebP is often the best default. The only time to avoid it is when a file needs to open in older software that predates WebP support.

How transparency changes the choice

If any part of your image needs to be see-through — a logo to sit on a coloured background, for example — JPG is off the table because it has no transparency channel. That leaves PNG (lossless, larger) or WebP (smaller, still supports transparency). For a transparent logo on the web, WebP usually wins; PNG is the safe, universally-compatible fallback.

Converting between formats

Switching formats is quick and you don’t need to install anything. Our Image Converter turns PNG, JPG, and WebP into one another right in your browser — your files never get uploaded. If your goal is mainly a smaller file rather than a specific format, the Image Compressor resizes and re-encodes in one step, and the Image Resizer handles exact dimensions.

A practical workflow

For a typical website image: start from the original, resize it to the largest size it will actually display at, then export as WebP at around 80% quality (or JPG if you need maximum compatibility). That combination — right dimensions plus the right format — is where the big file-size savings come from.
