Frequently Asked Questions

For screenshots, 60 to 75 usually looks indistinguishable from the original and saves a lot. For photographs with smooth skies, stay above 80. Check at full zoom rather than trusting the number blindly.

No, because the tool always works from the file you upload and hands you a new download. Your original stays untouched, so you can always go back and try a different setting.

A great deal. The same screenshot can be 2 MB at high quality and under 100 KB near the low end, and a detailed photograph often halves in size with barely any visible change.

Yes, set the slider to the level you are happy with and apply the same value across a batch so a gallery or catalogue keeps a consistent look.

About Image Quality Changer

Image quality and file size are the same dial. Turn quality up and the file grows but stays crisp; turn it down and the file shrinks, and somewhere in between is the point where the picture still looks fine on screen but weighs a fraction as much. The trouble is that almost every export dialog hides that dial behind a number, and the default is rarely what you actually want.

This tool gives you the control directly. Upload a jpg, jpeg, png or webp of up to 20 MB, drag the quality slider between 1 and 100, and watch the resulting file size update in real time next to a live preview. You can move the slider back and forth until the size and the appearance are both acceptable, then download.

Where the slider sits changes what you should expect. Text-heavy screenshots tolerate surprisingly low settings because the eye forgives JPEG artefacts on hard edges. Photographs, particularly skies and gradients, need a higher setting to avoid blotching. A useful habit is to check the result at 100 percent zoom, not just as a thumbnail, since compression artefacts hide at small sizes.

When to Use This Tool

Finding the lowest quality setting that still looks good, for a specific image rather than a global preset
Reducing a photograph just enough to clear a strict file size limit on an upload form
Balancing quality when a designer insists on large visuals and a developer insists on a small page weight
Re-saving a previously over-compressed image at a better setting before using it in a client presentation
