JPEG is conveniently small, but it costs detail. Every strong compression throw-away of information is not “put back” by sliding the quality setting higher later. AI can make a compressed photo look better; it does not restore original pixels that are already gone.
Compression versus noise
Compression artefacts are often blocky, with ringing around hard edges or muddy flat areas. Noise looks grainier and more random. Both can make a photo look “bad,” but they respond differently to editing.
| Symptom | Typical cause | First approach |
|---|---|---|
| Blocks / 8×8 pattern | Strong JPEG | Improve quality |
| Soft edges | Softness | Sharpen |
| Blocky when zoomed | Too few pixels | Increase resolution |
What you can do
- Find the original (camera export, cloud original, email attachment).
- Avoid repeatedly saving as a strong JPEG in the editing chain.
- Let AI try a clearer result via improve photo quality.
- Export the final result once and archive it.
Messaging apps and social media often compress aggressively. Ask for the original again from the photographer if needed, or check the camera roll. Privacy when uploading: AI and privacy in the Netherlands.
How to read a controlled example
An honest example shows the clean original (when available), the compressed input, and the AI result. Claim only what you see on those files — not a blanket “removes all JPEG damage.”
Saving without extra damage
When you share the result, choose a reasonable JPEG quality or PNG/WebP where that fits. Every new heavy compression pass can add artefacts again, even after AI.
Conclusion
Frequently asked questions
Does re-saving as a high-quality JPEG fix the problem?
No. Saving again at a higher quality setting does not bring discarded detail back. It can even damage the file further if you compress lossy again.
Can AI remove compression blocks?
Sometimes blocks and ringing look milder after AI enhancement, but it remains an approximation. Compare the result with the original, especially text and faces.
Which GoedkopeAI page should I use?
Start with improve photo quality. If it is mainly soft, choose sharpen a photo; if it is mainly too small, choose increase photo resolution.
