How to use Change the Quality of a JPG
- 1. Upload the JPG photo. Drop or browse for the .jpg or .jpeg file you want to re-encode. Its current file size shows so you have a baseline to compare against after the change.
- 2. Set the Quality (%). Move the Quality (%) slider: higher values preserve more visual detail but keep the file larger, lower values shrink the file at the cost of visible compression artifacts.
- 3. Download the re-encoded photo. The tool re-compresses the JPG at the quality level you chose. Download the result and compare the new file size against the original before deciding if it is enough.
When to use Change the Quality of a JPG
Change the Quality of a JPG re-encodes a photo at a chosen compression level, directly trading visual clarity for file size. It gives explicit control over that tradeoff instead of relying on an automatic optimizer.
- Testing how low quality can go before artifacts show. A designer drops quality to 60% to see how much file size savings are possible on photo.jpg before compression blocks become visible in flat areas.
- Meeting a strict upload size limit. A photo needs to shrink under a strict file size cap for a form; lowering the quality percentage brings the file down without changing its pixel dimensions.
- Preserving maximum detail for archival storage. A photo destined for long-term archival gets re-encoded at a high quality percentage to minimize compression loss compared to its original save.
- Reducing bandwidth for a mobile-heavy audience. A site serving mostly mobile visitors on limited data plans re-encodes hero images at a moderate quality percentage to cut load times.
Examples
