Compress Image to 500 KB

500 KB is generous: most photos fit at full resolution with quality you can't tell from the original.

The tool lowers quality first, then dimensions if needed, to get as close to your target as possible while keeping the photo sharp.

How to compress Image to 500 KB

  1. Add one or more photos — the target is 500 KB.
  2. Each photo keeps its full pixel size where possible; only very detailed images are scaled down a little.
  3. Download the results individually or as a ZIP.

What does this tool do?

A 500 KB cap is common on visa and immigration portals for supporting documents, on property and car listings, and in HR systems. A 12-megapixel phone photo (3–6 MB) can usually meet it at around 2,000–3,000 px wide with no visible difference on screen.

For scanned documents, keep them in colour only if colour matters — grayscale scans of text fit 500 KB at very high resolution. Your photos are processed in your browser and never uploaded.

Why use it?

  • Preset to 500 KB.
  • Keeps high resolution.
  • Great for documents and listings.
  • Batch processing.

Frequently asked questions

Will my photo lose quality at 500 KB?

Almost never visibly. Most phone photos fit at near full resolution with JPEG quality around 80–90%, which looks identical on screens.

How do I compress a scanned document to 500 KB?

Save the scan as JPEG and add it here. For multi-page documents, compress each page, then combine them with JPG to PDF.

Can I compress several photos at once?

Yes — add as many as you need and download them together as a ZIP.

Why is my file still over 500 KB?

Very detailed photos (foliage, gravel, text-heavy screenshots saved as PNG) need more space. The compressor will scale them down slightly to fit; choosing JPG output instead of PNG also makes a big difference.

Which pixel size should I use for a listing photo?

Around 1,600–2,000 px on the long side looks sharp on any screen, including retina displays, and fits easily under 500 KB.
