JPEG (Joint Photographic Experts Group) is the universal standard for photographic images, using lossy DCT-based compression to achieve 10:1 or higher compression ratios with minimal visible quality loss. First published in 1992, it supports 24-bit color and works across every device, browser, and application. The lossy nature means repeated editing and saving degrades quality—best used as a final delivery format.

JPEG excels at photographic content and remains the de facto standard for sharing, publishing, and web delivery. With mature encoders like MozJPEG delivering excellent quality-to-size ratios, JPEG continues to dominate despite newer alternatives.
WebP is Google's modern image format offering both lossy and lossless compression modes, plus alpha transparency and animation support—essentially combining the best features of JPEG, PNG, and GIF. Announced in 2010, WebP typically delivers 25-35% smaller files than JPEG at comparable quality using VP8 or VP8L compression. All major browsers now support WebP, making it a practical choice for web optimization.

WebP strikes an excellent balance between compression efficiency and ecosystem maturity. It's widely adopted for web delivery, supported across all modern browsers (Chrome 32+, Firefox 65+, Safari 14+, Edge 18+), and offers better compression than JPEG/PNG without the encoding overhead of AVIF.
CMS support: WordPress 5.8+ (July 2021) supports WebP natively. Most modern CMS platforms and CDNs (Cloudflare, Akamai, Fastly) can automatically serve WebP to compatible browsers via content negotiation.
Email limitation: Most email clients (Outlook, Gmail web, Apple Mail) do not support WebP. Always use JPG or PNG for email images, or provide a JPG fallback via <picture> elements in HTML emails.
Frequently Asked Questions
Why convert JPG to WebP instead of sticking with JPEG?
WebP is the modern successor to JPEG. At equivalent visual quality, WebP achieves 25-35% smaller file sizes compared to JPEG, resulting in:
- Faster page loads: Smaller files = faster downloads, especially on mobile networks
- Lower bandwidth costs: Reduced data transfer for you and your users
- Better Core Web Vitals: Improves Google's Largest Contentful Paint (LCP) metric
- Universal browser support: 93% global browser support (Chrome, Firefox, Safari, Edge)
For cutting-edge compression, our JPG to AVIF converter achieves 20-40% smaller files than WebP, though with slightly lower browser support (92% vs 93%).
How much file size reduction can I expect?
JPG to WebP conversion typically achieves 25-35% file size reduction with quality 85 encoding (equivalent to JPEG Q90-92 perceptually).
Examples:
- 1 MB JPEG photo → 650-750 KB WebP (25-35% reduction)
- 5 MB JPEG portrait → 3.25-3.75 MB WebP (25-35% reduction)
- 500 KB JPEG product shot → 325-375 KB WebP (25-35% reduction)
The exact reduction depends on image complexity: photos with smooth gradients compress slightly better than images with heavy texture/detail.
Will I notice quality loss?
Is WebP compatible with all browsers?
Yes. WebP is supported by 93% of global browsers as of 2025:
- Chrome: Since 2014 (version 32)
- Firefox: Since 2019 (version 65)
- Safari: Since 2020 (version 14 / iOS 14)
- Edge: Since 2018 (version 18)
- Opera: Since 2012 (version 12.1)
The only notable exception is Internet Explorer (discontinued June 2022). For legacy support, use the HTML <picture> element with JPEG fallback. Want even better compression for modern browsers? Try our JPG to AVIF converter for 20-40% smaller files than WebP.
Does WordPress support WebP?
Yes. WordPress has supported WebP natively since version 5.8 (July 2021). You can upload, manage, and serve WebP images just like JPEG or PNG without any plugins.
- Native support: WordPress 5.8+ handles WebP uploads, resizing, and thumbnail generation
- Older WordPress: Plugins like ShortPixel, Imagify, or EWWW can add WebP support
- CDN integration: Cloudflare, Fastly, and most modern CDNs can auto-convert to WebP based on browser support
For best results, keep original JPEGs as source files and let your CMS or CDN serve WebP to compatible browsers automatically.
Can I use WebP images in emails?
No, not reliably. Most email clients do not support WebP images:
- Outlook: No WebP support (desktop and web versions)
- Gmail (web): No WebP support in email body
- Apple Mail: No WebP support
- Yahoo Mail: No WebP support
Recommendation: Always use JPEG or PNG for email images. If you've converted to WebP for web use, keep your original JPEGs for email campaigns.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |

How are credits calculated for this conversion?
Cost: 1 credit per 25 MB
How it works:
- Files up to 25 MB: 1 credit (minimum)
- 26-50 MB: 2 credits
- 51-75 MB: 3 credits
- 76-100 MB: 4 credits
- Over 1000 MB: 40 credits (maximum cap)
Example: A 5 MB image = 1 credit. A 95 MB image = 4 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
| Business | — | 30,000 credits/month |
Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.
Note: With 1 credit per 25 MB, images under 25 MB cost 1 credit each. Pro users can convert 10,000 images per month.
