How to Convert PNG to JPG Online Free
Why convert PNG to JPG?
The main reason to convert PNG to JPG is file size. PNG uses lossless compression, which means every pixel is stored exactly — resulting in larger files. JPG uses lossy compression, which discards some image data to achieve much smaller files. As a result, converting PNG to JPG can reduce file size by 60–80% for photographic images.
Furthermore, smaller files improve website performance. If you have product photos, blog images, or any photographic content saved as PNG, converting PNG to JPG — or better yet, to WebP — will significantly reduce your page load times and improve SEO rankings.
A typical 2MB PNG photograph converts to approximately 300–500KB as a JPG at 85% quality — a 75–85% reduction in file size with no visible quality difference on screen.

What happens to transparency when converting PNG to JPG?
This is the most important thing to understand when converting PNG to JPG. JPG does not support transparency — it has no concept of transparent pixels. As a result, when you convert a PNG with a transparent background to JPG, the transparent areas must be filled with a solid colour.
Most PNG to JPG converters fill transparency with white by default. However, our converter lets you choose any background colour before converting. Common choices include:
- White — the standard choice for documents, product images on white backgrounds, and most web use
- Black — useful for images designed to appear on dark backgrounds
- Custom colour — match the background colour of the page where the image will be used
If your PNG contains a transparent background that needs to remain transparent — such as a logo that sits on various coloured backgrounds — do NOT convert it to JPG. Instead, keep it as PNG or convert to WebP, which supports transparency. Converting a transparent logo to JPG will permanently fill the background with a solid colour.
Which quality setting to use when converting PNG to JPG
The quality setting determines how much image data is discarded during PNG to JPG conversion. Higher quality means larger files but better image fidelity. Here are the recommended settings for different use cases:
- 90–95% — near-lossless quality for hero images, product photos, and any image where detail is critical
- 80–85% — the sweet spot for most web images. Significant file size reduction with no visible quality difference on screen
- 70–80% — good for thumbnails, preview images, and any image displayed at small sizes
- Below 70% — visible compression artefacts appear. Only use for very small thumbnails where quality is less important
When NOT to convert PNG to JPG
Converting PNG to JPG is not always the right choice. There are several situations where you should keep your image as PNG or convert to a different format instead:
- Images with transparency — if the PNG has a transparent background that must remain transparent, keep it as PNG or convert to WebP
- Screenshots with text — JPG compression creates visible artefacts around sharp text and UI elements. PNG or WebP lossless produces much better results for screenshots
- Logos and icons — logos need sharp edges that JPG compression degrades. Use SVG for vector logos or PNG/WebP for raster logos
- Images you plan to edit further — if you are going to re-edit and re-save the image, keep it as PNG. Each time you save a JPG, quality degrades slightly
PNG to JPG vs PNG to WebP — which is better?
In most cases, converting PNG to WebP is a better choice than converting PNG to JPG. Here is why:
- Smaller files — WebP produces 25–35% smaller files than JPG at equivalent quality. As a result, WebP gives you better compression than JPG.
- Transparency support — unlike JPG, WebP supports transparency. Therefore, PNG images with transparent backgrounds can be converted to WebP without losing the transparency.
- Better quality at same file size — WebP achieves better visual quality than JPG at the same file size due to its more modern compression algorithm.
- Browser support — WebP is supported by all modern browsers including Chrome, Firefox, Safari 14+, and Edge. Furthermore, over 97% of web users can view WebP images.
The only reason to choose JPG over WebP is when you need maximum compatibility — for example, when sending images via email or uploading to platforms that may not support WebP. For website use, WebP is almost always the better choice. Read our complete format comparison guide for more details.
Frequently asked questions
Does converting PNG to JPG reduce quality?
At quality settings of 80% or above, the visual difference between the original PNG and the converted JPG is essentially invisible on screen. However, JPG does permanently discard some image data — so the converted file is technically lower quality than the original PNG. For critical archival purposes, always keep the original PNG. For web use, 80–85% quality JPG is perfectly adequate.
Can I convert PNG to JPG without losing transparency?
No — JPG does not support transparency. When converting PNG to JPG, transparent areas are filled with a solid background colour. If you need to preserve transparency, convert to WebP instead, which fully supports transparent backgrounds just like PNG.
How do I convert PNG to JPG on iPhone or Android?
Open your mobile browser and go to our free image converter. Tap the upload area, select your PNG from the Photos app or gallery, choose JPG as the output format, and tap Convert. Download the JPG to your device instantly. No app installation required.
Will converting PNG to JPG make the image blurry?
At quality settings of 80% and above, converted JPG images look sharp and identical to the original when viewed on screen. However, JPG compression can create subtle artefacts around sharp edges and text at lower quality settings. For images with text or sharp geometric shapes, use 85%+ quality or consider WebP lossless instead.
