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.
PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.
Frequently Asked Questions
Will converting JPG to PNG improve image quality?
Why are PNG files so much larger than JPG?
When should I convert JPG to PNG?
Convert when you need:
- Lossless editing: Prevents generational quality loss from repeated saves in image editors.
- Format compatibility: Some tools/workflows require PNG (print services, game engines).
- Transparency support: PNG supports alpha channel (though your JPG source won't have any).
- Archival storage: Lossless format for permanent preservation.
Don't convert if: You're just sharing photos online. JPEGs are smaller and faster to load. Only convert if you have a specific need for PNG. For web optimization with smaller files, consider our JPG to WebP converter instead.

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.
