Compress JPEG to 500KB

Set a 500 KB ceiling and add a JPEG file; the page re-encodes it in your browser and keeps stepping quality and dimensions down until the file fits inside 500 KB. Because both are search variables, detail is preserved for as long as the budget allows instead of being thrown away at a fixed setting.

Target output: 500KB or smaller The browser will adjust JPEG quality and, when needed, dimensions to reach the selected limit. Review the preview before downloading.

Perguntas frequentes sobre compressão de Image

Is 500 KB enough to keep a full-page scan legible?

For most A4 pages, yes. Text stays readable at roughly 1000 × 1400 px, which fits inside 500 KB at a moderate quality setting, so there is usually no need to compress further.

Why is the result still not exactly 500 KB?

Encoders trade quality against bytes, so the output lands at or just under the 500 KB target rather than on it to the byte. Tighten or loosen the setting and run again until the size fits.

How much of the 500 KB budget goes to dimensions and how much to quality?

The page tries the largest clean frame that still fits first, then lowers quality only when size alone cannot reach 500 KB. Check the reported output size before you publish.

Will my original file be changed?

The result is downloaded as a separate file. Keep your original until you have checked the JPEG file at or under 500 KB.

What should I check before using the result?

Open the JPEG file at or under 500 KB in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

How accurate is the Compress JPEG to 500KB tool?

The tool is engineered for high precision. It processes the image and applies compression algorithms specifically calculated to bring the file size as close to the 500KB target as possible. In most cases, the final output will be at or very near the desired size, ready for immediate use.
