Right-click, "Save image as…", and there it is: a choice between PNG and JPG. Two little formats that trip up more people than almost anything else in everyday image work. The good news is that the difference is genuinely simple, and once it clicks you'll never second-guess it again.
Here's what each one is, the single real difference that matters, and exactly when to reach for each in 2026.
The quick answer
If you're in a hurry:
- Use JPG for photos — anything with lots of colors and gradients, like a picture from your camera or phone.
- Use PNG for graphics — logos, icons, screenshots, text, or anything that needs a transparent background.
That one rule covers about 90% of situations. The rest of this guide explains why, so you can handle the other 10% with confidence.
What is a JPG?
JPG (also written JPEG) is a lossy format built for photographs. "Lossy" means it shrinks files by throwing away detail your eye is unlikely to notice — subtle color shifts, fine noise, tiny gradients. The trade is fantastic: a photo that would be huge as a raw file becomes a small, shareable JPG that still looks great.
The catch is that JPG doesn't support transparency, and every time you re-save a JPG it loses a little more quality. It's brilliant for photos and poor for sharp-edged graphics — text and hard lines pick up fuzzy "artifacts" around them.
What is a PNG?
PNG is a lossless format. It keeps every single pixel exactly as it is, which makes it perfect for images where sharpness matters — logos, icons, screenshots, and anything with crisp text. PNG also supports transparency, so a logo can have no background and sit cleanly on any color.
The downside: because it preserves all that detail, a PNG of a photograph is often several times larger than the same photo as a JPG — for no visible benefit.
The key differences at a glance
| JPG | PNG | |
|---|---|---|
| Compression | Lossy (smaller) | Lossless (larger) |
| Transparency | No | Yes |
| Best for | Photos | Graphics, logos, text |
| Re-saving | Loses quality each time | Stays identical |
| Typical file size | Small | Larger |
When to use each
Put it into practice:
- Camera or phone photo → JPG. Smaller file, no visible quality loss.
- Logo or icon → PNG. Keeps edges crisp and supports a transparent background.
- Screenshot → PNG if it has text you need sharp; JPG is fine for a screenshot of a photo.
- Website image → JPG for photos to keep pages fast; PNG for graphics that need transparency.
- Image you'll keep editing → PNG, so you don't lose quality with every save. Export the final version to JPG if it's a photo.
How to convert between them
Picked the wrong one, or need to switch? It takes seconds:
- Shrink a big graphic for the web with PNG to JPG (you'll pick a background color to replace any transparency).
- Get a lossless, editable copy with JPG to PNG.
- Squeeze any photo further with the Image Compressor.
All of these run right in your browser on Pixveil — your images are never uploaded to a server, so even sensitive graphics stay private.
Rule of thumb: if it's a photo, JPG. If it has text, sharp edges, or transparency, PNG.
Frequently asked questions
PNG is technically higher quality because it's lossless — it keeps every pixel. But for photographs you won't see the difference on screen, and the JPG file is far smaller. For photos, JPG is the practical winner; for graphics, logos, and text, PNG wins.
Converting adds one round of JPG compression, which is usually invisible for photos. The bigger change is that transparency is lost — it gets filled with a background color. Keep the original PNG if you think you might need the transparent version again.
JPG (or the newer WebP) for photos, so pages load fast, and PNG for logos or graphics that need a transparent background. Large PNG photos are one of the most common causes of slow-loading pages.
PNG is lossless, so a photo saved as PNG carries an enormous amount of data. If it's a photograph and you don't need transparency, converting it to JPG shrinks the file dramatically with no visible quality loss.
