About PNG →

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.

About JPG →

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.

Frequently Asked Questions

What happens to transparent backgrounds in my PNG?

JPEG doesn't support transparency. All PNG alpha channels (transparency) are automatically flattened to a white background (#FFFFFF) during conversion.

Need a different outcome?

  • Preserve transparency: Use our PNG to WebP converter (30-50% smaller, full alpha)
  • Need colored background: Add background in an image editor before converting
  • Logos/graphics: Keep as PNG for transparency or convert to SVG

White background prevents black artifacts and matches how browsers display transparent PNGs on white pages.

How much file size reduction can I expect?

PNG to JPG conversion typically achieves 70-95% file size reduction with quality 90 JPEG encoding. Photos and gradients compress better than screenshots with text or sharp edges.

Will I notice quality loss?

For photos and natural images, quality 90 JPEG is visually indistinguishable from PNG in most viewing contexts. For screenshots or graphics, you may notice slight softening around sharp edges—a trade-off for dramatic file size reduction. For screenshots with transparency, try our PNG to WebP converter for lossless compression with 30-50% smaller files.

When should I keep PNG instead of converting to JPG?

Keep PNG when: You need transparency, plan to edit further, have screenshots/graphics with sharp edges, or require pixel-perfect lossless quality.

Convert to JPG when: Sharing photos online, file size is critical (70-95% smaller), images don't need transparency, or uploading to services with size limits. For web use with transparency, consider our PNG to WebP converter instead.

What if I need to convert JPG back to PNG later?

JPG to PNG conversion won't restore lost quality. Once compressed to JPG, data is permanently lost. Use our JPG to PNG converter if you need PNG format, but the image won't gain detail—it just changes the container. Keep your original PNGs if you might need them later.

Is PNG to JPG good for screenshots?

It depends on the screenshot content. For photos in screenshots, JPG works great (70-95% smaller). For UI screenshots, text, or diagrams with sharp edges, PNG preserves crispness better. If you need smaller screenshots with transparency, try our PNG to AVIF converter—50-70% smaller than PNG with better quality than JPG.

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:

TierDaily LimitMonthly Limit
Free50 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.
