What is PNG to JPG conversion?
This tool converts PNG images into the JPG format, entirely in your browser with no upload. PNG is a lossless format with transparency support, so quality never degrades when you save. It is ideal for logos, icons, screenshots with text and images with transparent backgrounds, but files tend to be larger. JPG (JPEG) is a lossy format without transparency that compresses photographs to a small size. It is the most universal format for camera and web photos, at the cost of losing a little quality each time it is saved.
How to use it
- Select or drop in your PNG image.
- The tool converts it to JPG locally, instantly.
- Click Download to save the JPG file.
When should you convert PNG to JPG?
PNG files are common for graphics and screenshots, but their lossless compression can make photos unnecessarily large.
Converting PNG to JPG is worthwhile when you want to shrink the file a lot and do not need transparency — especially for photos, where it saves significant space and is easy to upload or email. Note that JPG drops transparency and can add compression artifacts around sharp text or edges.
PNG vs JPG: key differences
| Property | PNG | JPG |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | Yes | No |
| Best for | Logos, icons, screenshots, transparent graphics | Photographs, camera images, web photos |
When does PNG-to-JPG actually pay off?
A screenshot or a photo exported as PNG can easily balloon past several megabytes, and that is exactly when an email attachment or an upload form rejects it. Converting those PNGs to JPG usually cuts the size to a third or less, which makes them far easier to send and to post. Two things are worth watching, though:
- Any transparent area is flattened to white, so a cut-out logo suddenly sits on a white block.
- Sharp text and thin lines in a screenshot pick up blocky JPG artifacts around the edges.
When the image is mostly crisp text, it is usually better to keep the PNG.
When does this conversion make the file bigger instead?
The answer is not in the format, it is in the picture — and our own four rows straddle that line. A photograph goes 1.88 MB → 288.4 KB (-85%), which is the reason JPEG exists. The same conversion on a UI screenshot goes 18.0 KB → 43.5 KB (+142%) — more than double. JPEG has to spend bits describing the one-pixel-wide hard edges in a screenshot, while PNG encodes them almost for free. A logo with transparency is a third case: 28.8 KB → 16.3 KB (-43%) — a saving, but the alpha channel is gone and will not come back. The test is easy: zoom in on an edge. Soft, grain everywhere → convert. Large flat areas, crisp text → keep the PNG.
