What is PNG to JPG conversion?
PNG uses lossless DEFLATE compression that preserves every pixel exactly, which is essential for graphics with sharp edges, text overlays, and transparent backgrounds. When you convert PNG to JPG, the encoder applies a discrete cosine transform on 8x8 blocks and discards high-frequency detail that the human eye is unlikely to notice (see the JPEG specification ITU-T T.81). This lossy process enables 70-90% file size reduction on photographic content. The conversion also flattens any alpha channel onto a solid matte, since JPG has no concept of transparency; this tool composites against white by default. The most common scenario is preparing screenshots and web graphics for sharing. macOS, Windows Snipping Tool, and Figma exports all default to PNG. These files are great for editing but oversized for email and CMS uploads. A 4-8 MB desktop screenshot typically becomes under 400 KB as JPG with no visible difference at screen resolution. One technical caveat worth flagging: JPG's default 4:2:0 chroma subsampling averages colour information across 2x2 pixel blocks, which can produce visible fringing on flat-colour UI screenshots and saturated red text. At 90% quality this tool retains 4:4:4 subsampling on the luma channel, but designers working with brand-saturated reds and oranges should still preview the output. For pure flat-colour graphics, WebP is usually a better target than JPG.
Why convert PNG to JPG?
- Reduce file size by up to 80% compared to PNG for photographic images
- JPG is accepted by virtually every app, printer, and email client
- Social media platforms prefer JPG for uploaded photos
- Remove transparency channel when it is no longer needed
What is the difference between PNG and JPG?
The table below compares PNG vs JPG across key format characteristics.
| Feature | PNG | JPG |
|---|---|---|
| File extension | .png | .jpg |
| Compression type | Lossless | Lossy |
| Transparency support | Yes (alpha) | No |
| Animation support | No | No |
| File size | Larger | Smaller |
| Best use case | Graphics, transparency | Photographs |
| Browser support | Universal | Universal |
Choose PNG for graphics with transparency; choose JPG for photographs where smaller file size matters.
Frequently asked questions
Does converting PNG to JPG lose image quality?
Yes, slightly. JPG uses lossy compression, so fine details may soften compared to the original PNG. This tool uses high quality settings (90%) to minimise visible differences.
Can I convert the JPG back to PNG without quality loss?
No. Converting a JPG back to PNG creates a lossless copy of the already-compressed JPG data. The quality lost during the original PNG-to-JPG conversion cannot be recovered.
Why is my JPG file so much smaller than the PNG?
PNG is lossless and stores every pixel exactly, which results in larger files. JPG discards subtle detail the eye rarely notices, allowing it to represent the same image at a fraction of the size.
Why is my PNG screenshot 5 MB but the same image as JPG is under 500 KB?
PNG stores every pixel losslessly, which produces large files especially for photos and screenshots with gradients. JPG discards imperceptible detail, achieving 80-90% size reduction for photographic content with no visible difference at high quality settings.
What happens to the transparent background in my PNG when I convert to JPG?
JPG does not support transparency. Any transparent areas in your PNG are composited onto a white background during conversion. If the transparent region is important, convert to WebP instead, which supports both transparency and good compression.
Is PNG to JPG the best conversion for optimizing website images?
It depends on the image. For photographs, JPG is a solid choice with universal browser support. However, WebP and AVIF offer 25-50% better compression than JPG at equivalent quality. If your site targets modern browsers, consider PNG to WebP or PNG to AVIF for maximum performance.
Will text in my PNG screenshot remain readable after converting to JPG?
Yes. At 90% quality, text in screenshots remains sharp and fully readable. JPG compression artifacts are most noticeable around high-contrast edges at very low quality settings. At the quality level this tool uses, text clarity is preserved for all practical purposes.
Does PNG to JPG preserve EXIF metadata such as camera info and GPS?
Yes. The underlying sharp/libvips pipeline carries EXIF, ICC, and XMP metadata across the conversion when present. Most PNGs from screenshots and design tools do not contain EXIF, but PNGs exported from cameras or Lightroom retain capture metadata in the resulting JPG.
How is the transparent background handled — can I pick a colour other than white?
JPG cannot store transparency, so this tool composites alpha pixels onto a solid white matte before encoding. If you need a different matte colour (for example, to match a dark website background), composite the PNG against your target colour in an editor first, then convert. Otherwise switch the output to WebP, which keeps the alpha channel.
I work in Display P3. Will my wide-gamut PNG colours survive PNG-to-JPG?
JPG can carry an embedded ICC profile, and the converter preserves the source profile when present. However, many viewers ignore JPG ICC profiles and assume sRGB, which can desaturate Display P3 reds and greens. For colour-critical web work, convert your PNG to sRGB before exporting to JPG, or use AVIF, which has stronger wide-gamut support.
