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

Choosing the wrong image format can make a website slow, a logo blurry or a photo unnecessarily huge. The good news is that the decision is simple once you understand what each format is good at. This guide compares the most common formats and gives you a quick rule of thumb for every situation.

The quick answer

JPG (JPEG)

JPG has been the standard photo format since the 1990s. It uses lossy compression, discarding details the human eye barely notices. At quality 75–85%, a JPG looks nearly identical to the original while being many times smaller than an uncompressed image.

Strengths: universal support, small photo files, adjustable quality. Weaknesses: no transparency, blocky artifacts at low quality, loses quality every time it is re-saved, poor for text and sharp lines.

PNG

PNG is lossless: every pixel is stored exactly. It supports full transparency with smooth, semi-transparent edges.

Strengths: perfect quality, transparency, excellent for text, logos and screenshots. Weaknesses: photos saved as PNG are typically 5–10 times larger than JPG.

Tip: if a PNG file is too large, it is often a photo that should be a JPG, or a graphic that can be compressed with color quantization.

WEBP

WEBP was developed by Google as a modern replacement for both JPG and PNG. It supports lossy and lossless compression, transparency and animation. At the same visual quality, WEBP files are usually 25–35% smaller than JPG and much smaller than PNG.

All modern browsers support WEBP, which is why it is the recommended format for websites. Faster pages improve user experience and Google's Core Web Vitals.

The only downside: some older software, image editors and upload forms still refuse WEBP. In that case, convert back to JPG or PNG.

AVIF

AVIF is the newest format, based on the AV1 video codec. It can be even smaller than WEBP, especially for photos. Browser support is now good, but editing software and social networks are still catching up. It is a great choice for performance-focused websites that offer a fallback.

SVG

SVG is different: it is a vector format made of shapes described in code, not pixels. It stays perfectly sharp at any size and is often tiny. Use it for logos, icons and simple illustrations on websites. It is not suitable for photographs.

GIF

GIF is an old format limited to 256 colors. It is still used for short animations and memes, but WEBP animations and short MP4 videos are dramatically smaller and look better.

Converting between formats

Once you know which format you need, converting is easy:

• Photo that must be uploaded to a form → PNG to JPG
• Website images → JPG to WEBP or PNG to WEBP
• Downloaded WEBP that will not open → WEBP to JPG
• Mixed batch of formats → the universal converter below

Final checklist

1. Is it a photo? → JPG for sharing, WEBP for websites.
2. Does it need transparency? → PNG or WEBP.
3. Is it a logo or icon? → SVG if possible, otherwise PNG.
4. Does it contain small text? → PNG.
5. Is it too big? → Resize first, then compress.

Following these rules will make your images look better, load faster and work everywhere they need to.
