PNG files are lossless and large. Converting to JPG can reduce file size by 60–80% — without visible quality loss for photos — making them faster to load and easier to share.
When does it make sense to convert PNG to JPG?
- Photos and complex images — JPG handles gradients and colour transitions far more efficiently than PNG.
- Reducing file size for email or upload — many platforms have size limits; a 3 MB PNG often becomes a 400 KB JPG.
- Social media and web uploads — platforms like Instagram, Facebook, and WordPress re-compress PNGs anyway. Upload JPG and control the quality yourself.
- Removing unused transparency — if your PNG doesn't actually use transparency, there is no reason to keep the larger format.
When to keep PNG instead
- Logos, icons, or graphics with a transparent background.
- Screenshots with sharp text (JPG artifacts make text look blurry).
- Images you plan to edit further — always work in lossless formats and export JPG as the final step.
Convert PNG to JPG — step by step
- Click the upload area below and select your PNG file (or drag and drop it).
- In the To dropdown, select JPG.
- Adjust quality if needed (85% is a good default for photos; use 90%+ for graphics).
- Click Convert and download your JPG file.
Quality settings for PNG to JPG
The quality slider controls how much compression is applied to the JPG output:
- 90–100% — near-lossless. File is still noticeably larger than lower settings. Use for print-quality exports.
- 80–89% — the sweet spot for most web images. Smaller file, no visible artifacts.
- 70–79% — good for thumbnails and previews where file size matters more than pixel-perfect quality.
- Below 70% — visible compression artifacts. Avoid for anything except tiny thumbnails.
FAQ: Converting PNG to JPG
Does converting PNG to JPG lose quality?
A small amount of quality is lost because JPG uses lossy compression. At quality 85% or higher the difference is invisible for photos. For graphics with sharp lines and text, you may notice slight blurring around edges — in those cases, PNG is the better format to keep.
What happens to the transparent background?
JPG does not support transparency. Transparent areas in your PNG will be filled with a solid colour — white by default. Use the background colour picker in the converter to choose a different fill colour.
Will the file size always decrease?
For photos — yes, significantly. For small PNG graphics with few colours (like icons), the JPG may actually be larger because JPG is optimised for photographic content, not flat graphics.
