JPG, PNG or WebP: Which Image Format Should You Use, and When?
Photos, logos, screenshots, website images and form uploads each suit a different image format. Here's a plain guide to JPG, PNG and WebP, with simple rules for which one to use and when to convert.
Use JPG for photos and form uploads, PNG for logos, screenshots and anything with a transparent background, and WebP for images on your own website. Choosing the right image format keeps files small, sharp and accepted. When something doesn't fit, convert a copy with the free H View Image Converter.
Most of us never think about image formats until something breaks: a portal rejects a PNG, a logo gets an ugly white box around it, or a website loads slowly because every image is a 3 MB JPG. Three formats cover almost everything you'll do, and each has a clear job.
What Is the Difference Between JPG, PNG and WebP?
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes | Yes |
| Best for | Photos, form uploads, sharing | Logos, screenshots, diagrams, text | Website and blog images |
| Accepted by forms and old apps | Almost everywhere | Often | Not always |
MDN's image format guide describes JPEG as particularly useful for photographs, PNG as preferred when transparency or precise reproduction is needed, and WebP as offering much better compression than PNG or JPEG. According to Google, lossless WebP files are 26% smaller than PNGs and lossy WebP files are 25–34% smaller than comparable JPEGs.
Which Format for Which Job?
- Government, exam and job forms: JPG, unless the notice says otherwise.
- WhatsApp and email photos: JPG.
- Logos and stickers: PNG (or WebP) to keep transparency.
- Screenshots with text: PNG, so letters stay crisp.
- Your website or blog: WebP, with JPG as a fallback for very old browsers.
- Print shops: high-quality JPG or PNG; ask what they prefer.

- PNG to JPG: transparent areas become white (or a colour you choose), and the file usually gets much smaller.
- JPG to PNG: the file gets bigger but no sharper; lost detail doesn't come back.
- WebP to JPG: fixes “unsupported file” errors in apps and portals.
- Repeated JPG saves: each lossy save loses a little detail, so keep originals and convert copies.
