JPG vs PNG vs WebP — Which Image Format Should You Use?
Choosing the wrong image format costs you either quality or file size — sometimes both. JPG, PNG, and WebP each make different trade-offs, and understanding those trade-offs takes about five minutes. After that, the choice for any given image is usually obvious.
JPG — the photographer's format
JPEG (JPG) uses lossy compression. It permanently discards image data to produce small files, and it's extremely good at this for photographs. At quality settings of 75–85%, the compression artefacts are invisible to most people while the file is 5–10× smaller than an uncompressed original. It supports all colours, renders gradients smoothly, and is universally supported everywhere.
JPG's limitation: it doesn't support transparency, and re-saving a JPG repeatedly causes cumulative quality loss (each save recompresses what was already compressed). It also produces visible artefacts on graphics with sharp edges, text, and large flat-colour areas — the compression algorithm struggles with these.
PNG — the designer's format
PNG uses lossless compression. No data is discarded, so the quality is identical to the original at any zoom level. It supports full transparency (alpha channel), making it the standard format for logos, icons, stickers, and any image that needs to sit on a coloured background. Text in PNGs stays sharp at any size.
PNG's limitation: for photographs, PNG files are significantly larger than JPGs — sometimes 3–5× larger for the same visual quality. For web use, large PNG photographs slow page load times considerably. Use PNG for graphics; use JPG for photos.
WebP — the web format of 2026
WebP is Google's modern image format that combines the best of both: it supports lossy compression (like JPG) and lossless compression (like PNG), and it supports transparency (like PNG). Files are typically 25–35% smaller than equivalent JPGs and 26% smaller than equivalent PNGs. All modern browsers support it.
For web use, WebP is almost always the better choice over JPG or PNG when you can control the output format. The exception: when uploading to platforms that don't support WebP natively (some social platforms still only accept JPG and PNG) or when compatibility with older software matters.
Quick decision guide
- Photograph for the web: WebP first, JPG as fallback
- Logo or icon (transparency needed): SVG if possible, PNG if not, WebP if both aren't available
- Screenshot or graphic with text: PNG or WebP lossless
- Printing: TIFF or uncompressed PNG
- Animated image: WebP or AVIF; GIF only if compatibility requires it

What is the best image format for websites?
WebP for most use cases — it's 25–35% smaller than JPG at equivalent quality and supports transparency like PNG. Use JPG as a fallback for older browsers or platforms that don't accept WebP. Use PNG for graphics where lossless quality and transparency are both required.
What is the difference between JPG and PNG?
JPG uses lossy compression (excellent for photos, no transparency). PNG uses lossless compression (perfect quality, transparency support, larger file sizes for photos). Neither is universally better — the right format depends on the content type.
Is WebP better than JPG?
For web use, yes — WebP produces 25–35% smaller files at the same visual quality and is supported by all modern browsers. For situations requiring maximum compatibility (printing, legacy software, platforms that don't accept WebP), JPG is still the standard.
Should I convert my PNG files to WebP?
Yes, for web use. WebP lossless is typically 26% smaller than PNG at identical quality, with full transparency support. Convert your PNGs to WebP for any web images you control. Keep the original PNG for editing purposes.
What image format should I use for social media?
Check each platform's current specifications. Most accept JPG and PNG; some now support WebP. For images you control (website, email), use WebP. For social media uploads, JPG is the safe default for photographs; PNG for graphics with text or transparency.
