Compress Image to 500 KB

Half a megabyte is the ceiling on many modern platforms: marketplace listing photos, real-estate portals, and website builders often reject anything above 500 KB. This tool brings your photo down to 500 KB or smaller, almost always without touching the dimensions, so listing photos keep their zoomable detail.

Size target

This page targets 500 KB or smaller. Quality is automatic: encoding quality steps down first, then the dimensions shrink, until the file fits. There is no quality slider because the target decides it.

Rotation

Output is always PNG so the transparent corners survive.

How to use Compress Image to 500 KB

  1. Choose or drop a JPEG, PNG, or WebP image.
  2. Pick the output format: JPG for the smallest files, WebP to keep transparency.
  3. Process the image. Quality is reduced first, then dimensions, until the file is 500 KB or smaller.
  4. Compare the result size, then download the generated file.

Supported behavior

  • The target is 500 KB or smaller. The result panel always shows the real output size.
  • The search runs locally: encoding quality steps down first, then the dimensions shrink in steps.
  • JPG usually reaches small targets at better quality; WebP keeps transparency when the browser supports it.

Best for

  • Marketplace listing photos capped at 500 KB.
  • Property and vehicle listing uploads.
  • Website-builder media libraries with a 500 KB limit.

Limits

  • Reaching a very small target can visibly soften detail, especially in photos with lots of texture.
  • If even the smallest sensible export stays above the target, the tool says so and hands you that smallest file instead of faking success.
  • The target counts bytes the way upload forms do: 500 KB means 512,000 bytes.

Privacy notes

  • Selected files stay on your device during processing; nothing is uploaded to a server.
  • Object URLs are revoked when previews or results are replaced.

Compress Image to 500 KB FAQ

My camera photo is 4 MB. Can it really reach 500 KB?

Yes — phone photos carry a lot of redundant detail. Re-encoding at a sensible quality usually lands well under 500 KB at full dimensions; the tool only shrinks dimensions if quality alone is not enough.

Should I compress before uploading to a marketplace?

Most marketplaces recompress uploads anyway, which can soften them unpredictably. Sending a clean file just under their cap keeps you in control of the final quality.

What if my image is already under 500 KB?

The tool still re-exports it at high quality and reports the real result. If the original is already smaller and you do not need a re-export, there is nothing to fix — the result panel tells you the numbers either way.
