PNG vs JPG: Which Image Format Should You Use?
PNG is a lossless format built for sharpness and transparency. JPG is a lossy format built for small photo files. Here's exactly when to pick each.
PNG and JPG are the two most common image formats on the web, and picking the wrong one is the single most common reason images look blurry or weigh far more than they should. The short version: PNG is lossless and supports transparency, so it's ideal for graphics, logos, screenshots and anything with sharp edges or text. JPG is lossy and produces much smaller files for photographs, so it's ideal for photos and rich, detailed images where a tiny quality trade-off is invisible.
The reason they behave so differently comes down to how each one stores pixels. PNG keeps every pixel exactly as it was, which is why a screenshot stays crisp, but that fidelity costs bytes. JPG throws away detail the human eye barely notices to shrink the file dramatically, which is brilliant for a sunset photo and terrible for a screenshot of text, where the discarded detail shows up as fuzzy 'artifacts' around the letters.
Below is a side-by-side breakdown, a clear rule for choosing, and the honest verdict: followed by the free converters to switch either direction in your browser.
PNG vs JPG, compared
Every dimension that actually affects the decision, at a glance.
| Dimension | PNG | JPG |
|---|---|---|
| Compression | Lossless, every pixel preserved exactly, no quality loss ever. | Lossy, discards fine detail to shrink the file. Quality is adjustable. |
| Transparency | Full alpha transparency (transparent backgrounds supported). | None. No transparency. Empty areas become white or black. |
| File size | Larger, especially for photographs. | Much smaller for photos: often 5–10× smaller than PNG. |
| Best for | Logos, icons, screenshots, text, line art, flat graphics. | Photographs and detailed, colorful, real-world images. |
| Color support | Up to 16 million colors plus an 8-bit alpha channel. | Up to 16 million colors. No alpha channel. |
| Editing / re-saving | Re-save as often as you like. No degradation. | Each re-save loses more quality (generation loss). |
| Web performance | Heavier: can slow page loads if used for photos. | Lightweight: the default for photographic web images. |
Which one is right for you?
Choose PNG when
- You need a transparent background (logos, badges, product cutouts, UI assets).
- The image has sharp edges, text or flat color, screenshots, diagrams, line art.
- Quality must be pixel-perfect and survive repeated editing and re-saving.
- You're exporting graphics for a design system, app or print where crispness matters.
Choose JPG when
- The image is a photograph or a rich, detailed real-world scene.
- File size and fast page loads matter more than pixel-perfect edges.
- You're uploading many photos (galleries, e-commerce, social) and need them small.
- You don't need transparency and a tiny, invisible quality trade-off is fine.
The verdict
Use PNG for anything with transparency, text or sharp edges (logos, screenshots and graphics) and use JPG for photographs, where it delivers a near-identical image at a fraction of the size. If a photo doesn't need transparency, JPG is almost always the right call. If in doubt about a graphic, keep it PNG to stay crisp.
