How much does converting PNG to JPG reduce file size?

Typically 50–80% for photographs. A 3MB PNG photo converted to JPG at 90% quality might be 400–700KB. For screenshots and UI graphics, the reduction is usually 40–60%.

What quality setting gives the best file size reduction?

80–85% quality offers the best balance of size reduction and visual quality. Files are typically 60–75% smaller than PNG while remaining visually sharp. Use 70% for web thumbnails where maximum size reduction matters most.

Should I use JPG or compress the PNG instead?

Converting to JPG is the most effective method. Even a heavily compressed PNG is usually larger than a good-quality JPG because of the fundamental difference in compression algorithms. Start with JPG conversion, then compress further if needed.

Does a smaller file size mean lower quality?

At quality settings of 85%+, the quality reduction is imperceptible in most images. The "loss" in JPG is carefully chosen to discard information the human eye is least sensitive to. For critical professional use, always preview the output before finalising.

Can I reduce PNG file size without converting to JPG?

Yes — you can compress a PNG using the FixTools Image Compressor. PNG compression is lossless, so quality is perfectly preserved, but the file size reduction is smaller than converting to JPG.

What is the maximum file size reduction I can achieve?

With JPG conversion at 80% quality combined with further compression, reductions of 85–90% from the original PNG are achievable for photographs. Text-heavy screenshots and graphics typically achieve 50–70% reduction.

How It Works

Step-by-step guide to convert png to jpg to reduce file size:

1
Upload your large PNG file
Open the Image Format Converter and upload the PNG whose file size you want to reduce.
2
Select JPG as the output format
Choose JPG — this alone will typically reduce file size by 50–80% compared to PNG.
3
Set quality to 85–90%
Use 85–90% quality for the best balance of file size reduction and visual quality. Go lower (70–80%) for even smaller files if the image is for web thumbnails.
4
Check the file size comparison
The tool displays the original PNG size and the converted JPG size. If the result is still too large, lower the quality slider further.
5
Download your smaller JPG
Download the converted JPG. For further size reduction, use the Image Compressor after converting.
