JPG vs PNG vs WEBP vs SVG: Which Image Format to Use?
Use JPG for photos, PNG for logos, screenshots and transparent images, WEBP to make photos and graphics smaller on websites, and SVG for simple logos and icons that must stay sharp at any size. If in doubt for uploads and sharing, JPG is the safest choice.
The four formats at a glance
✓| Formato | Best for | Transparencia | File size | Works everywhere? |
|---|---|---|---|---|
| JPG | Photos | No | Small | Sí |
| PNG | Logos, screenshots, text | Sí | Large for photos | Sí |
| WEBP | Website photos and graphics | Sí | Smallest | Browsers yes, some apps no |
| SVG | Simple logos and icons | Sí | Tiny for simple shapes | Browsers yes |
JPG – the everyday photo format
🖼️ JPG throws away detail the eye barely notices, which keeps photos small. Every device, app and portal accepts it. The downside: each re-save loses a little more quality, and it cannot be transparent. Save photos as JPG once and edit from the original.
PNG – sharp edges and transparency
✓PNG keeps every pixel exactly, so text, lines and logos stay crisp and backgrounds can be transparent. That precision makes photos huge – a phone photo as PNG can be several times the size of the same JPG. Convert with PNG to JPG when a PNG photo is too big.
WEBP – smaller files for faster websites
WEBP, created by Google, supports both photo-style and lossless compression plus transparency, usually at noticeably smaller sizes than JPG or PNG. It is ideal for website images and helps page speed. Convert graphics with PNG to WebP, and turn WEBP files back into something every app opens with WEBP to PNG.
SVG – logos that never go blurry
SVG describes shapes with code instead of pixels, so a logo looks perfect on a phone and on a billboard. It suits flat logos and icons – not photos. Simple graphics can be traced with PNG to SVG or JPG to SVG.

Preguntas frecuentes
Which format is best for website photos?
WEBP if your site supports it, otherwise JPG. Both keep photos small; WEBP is usually smaller at the same quality.
When should I use PNG?
For logos, icons, screenshots, charts and anything with transparency or sharp text. PNG keeps edges crisp but makes photos large.
Is WEBP supported by all browsers?
All current versions of Chrome, Safari, Firefox and Edge display WEBP. Some older apps and editors still cannot open it.
What is SVG good for?
Simple logos, icons and illustrations. SVG is made of shapes, not pixels, so it stays sharp at any size and is often tiny.
Does converting JPG to PNG improve quality?
No. Converting cannot bring back detail that JPG compression removed; it only makes the file bigger.
Which format should I upload to government or job portals?
Usually JPG – it is the most widely accepted. Follow the size and KB limits in the instructions.
