When to use JPG
Where JPG is still the right answer in 2026, the quality range that actually matters, and the two things it fundamentally cannot do.
In short
Use JPG for photographs and for anything leaving the browser, where universal compatibility matters more than efficiency. It cannot store transparency and degrades every time it is re-saved.
JPG has been the default photograph format for thirty years, and it is still the right choice more often than its age suggests.
Use it for photographs
Lossy compression was designed for exactly this: continuous tone, smooth gradients, no hard edges. A photograph at 75% quality is very hard to distinguish from the original and a fraction of the size of the equivalent PNG.
Use it when the file leaves the browser
This is the strongest argument for JPG today. Email attachments, upload forms, print shops, older desktop software, internal business systems — nothing anywhere refuses a JPG. WebP is smaller and better, and it still gets rejected by things outside a web page.
The quality range that matters
| Quality | Use |
|---|---|
| 85–95 | Master copies, images that will be edited or printed |
| 70–80 | The everyday range — web, sharing, email |
| 55–70 | When size is tight and the image will be viewed small |
| Below 50 | Only when a hard limit leaves no choice |
What it cannot do
- Transparency. There is no alpha channel and never will be. Transparent areas are flattened onto a background colour.
- Survive repeated saving. Every re-save discards more; after a few rounds it is visible.
- Handle text and sharp edges well. Screenshots get a halo around every letter — use PNG or WebP.
Mistakes worth avoiding
- Using JPG for logos and screenshots. It is both uglier and often larger.
- Editing and re-saving the same JPG repeatedly instead of working from a lossless master.
- Choosing JPG for a web page when WebP is available and smaller.
