Format comparison
PNG (Portable Network Graphics) uses lossless compression and supports transparency. Ideal for logos and screenshots.
Pros
- ✓ Lossless compression
- ✓ Alpha transparency
- ✓ Great for sharp edges
Cons
- ✗ Larger file sizes
- ✗ Inefficient for photos
JPEG (Joint Photographic Experts Group) is the most widely used image format, ideal for photographs and images with gradients.
Pros
- ✓ Universal compatibility
- ✓ Adjustable compression
- ✓ Great for photos
Cons
- ✗ Lossy compression degrades quality
- ✗ No transparency support
When to Convert PNG to JPEG
Convert PNGs (screenshots/graphics) to JPEG when transparency isn’t needed and you want smaller files—for sharing, email, and uploads.
Technical Format Details
PNG Technical Specifications
Technical details
PNG is a lossless raster format that preserves pixel data exactly. It supports alpha transparency, which makes it a common choice for logos and UI assets.
Good for
- Logos/icons: Assets that need transparency- Screenshots: Crisp text and line art
Notes
- Photos: Files can be large (WebP/JPEG may be a better fit)- Quality setting: Since PNG is lossless, “quality” controls may have little or no effect
Reference: W3C: PNG 3rd Edition
JPEG Technical Specifications
Technical details
JPEG is a lossy format optimized for photos. Lower quality settings reduce file size, but can introduce artifacts around edges and text.
Good for
- Photos: Natural images with gradients- Sharing: Maximum compatibility
Notes
- Re-encoding: Repeated saves accumulate artifacts (use PNG for editing intermediates)- Transparency: Not supported
Reference: JPEG Committee
How to Use
Add files
Drop or click to select your PNG files (multiple supported)
Confirm output
Default is JPEG. You can change to another supported output format if needed.
Adjust options
Set quality, resize, and metadata options only if you need them.
Convert & download
Download each file, or download everything as a ZIP for batch outputs.
FAQ
What happens to a transparent PNG when converted to JPEG?
JPEG doesn't support transparency, so transparent areas become white.Keep it as PNG or use WebP if you need transparency.
How much smaller will the file be?
Photo-like images can shrink 50–80%. For text-heavy or illustrated images, JPEG artifacts may appear — use quality 85+ for those.
Is this good for screenshots?
Screenshots with few colors look best in PNG, but JPEG at quality 90 is practical when file size matters.
Will converting reduce image quality?
It depends on the output format. PNG is lossless, so quality stays the same. Lossy formats like JPEG/WebP/AVIF/JXL can change file size and appearance depending on the quality setting. Always verify with the final output before publishing.
Can I keep Exif metadata?
When "Keep Exif/Metadata" is ON, we try to carry over things like capture time, camera info, and GPS where possible. Some tags may be dropped depending on the input, output format, and browser environment. Turn it OFF if you want to remove location data before sharing.
Can I convert multiple files at once?
Yes. You can select multiple files, convert them in one run, and download each file individually. For multiple outputs, you can also download everything as a ZIP. For very large batches, splitting into smaller runs is more stable.
Are my images uploaded to a server?
No. Conversion runs locally in your browser, and your images are not sent to an external server.
What if conversion fails or is slow?
Some formats (like HEIC/HEIF) depend on browser support. If it fails, try another browser, reduce the number of files, or resize before converting.
