What Image Quality Setting Should You Use for a Website?

Ask five people for the best JPEG quality setting and you may get five different answers. One says 70, another says 85, and someone will insist that anything below 95 looks terrible. The trouble with all three answers is that the number is not a universal measurement of visual quality.

Different image encoders interpret quality values differently. A setting of 80 in one tool does not necessarily produce the same image or file size as 80 in another.

A sensible starting point

For an ordinary web photograph, try a moderate JPEG or WebP setting around 75 to 85, then inspect the output. Treat this as a starting experiment, not an official standard. Photographs of faces, products, and natural scenes can behave differently even at identical dimensions.

Look at the image at the size it will actually be displayed. Tiny artifacts may not matter in a small preview, but soft product labels or broken text certainly can.

What about PNG?

PNG is usually saved losslessly by the browser encoder. In VeyraPixel, the quality slider does not apply to PNG. If a PNG is too large, reduce unnecessary dimensions or compare a WebP output if the receiving application supports it.

Remember that a format choice can matter more than a change from quality 80 to 75. A full-color photograph stored as PNG can be much larger than its JPEG equivalent.

Test one variable at a time

Open the VeyraPixel tool and note the original file size. Keep dimensions fixed while comparing different JPEG or WebP quality values. Record the output size and inspect fine detail. Once you find an acceptable quality, consider whether the image can also be displayed at smaller dimensions.

You might discover that a smaller image at a moderately high quality looks better on the page than a huge image heavily compressed to the same number of bytes. That is a useful trade-off, not a rule for every picture.

Watch for the hidden costs

Higher quality often means a larger download, which matters for mobile visitors. Lower quality can make large smooth gradients show bands or cause printed text to break up. It can also reduce confidence in a product photograph if important textures look fake.

There is no perfect percentage that works for every file. Choose a suitable format, match dimensions to the actual display, and compare real outputs. If an upload portal imposes a strict KB limit, that constraint takes priority over a favorite slider number. See reducing JPG size for a more detailed workflow.

Keep a simple comparison log

When comparing results, write down just four things: output format, pixel dimensions, quality setting, and final bytes. Suppose one export looks clean at quality 82 and another has visible blocks at 55. That is more actionable than deciding that 55 is always bad or 82 is always safe. The content and encoder matter.

Try comparing a photograph, a graphic with text, and a logo separately. The photograph may be a good JPEG or WebP candidate, while the diagram could be clearer as PNG. Quality controls are not substitutes for choosing an appropriate format, and perceived quality is not captured by file size alone.
