Compress Image to 500KB
Free tool to compress or reduce any JPG, PNG or WebP image to 500KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 500KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 500KB. Nothing is uploaded; all compression happens on your own device.
Whether you want to reduce a photo to 500KB, resize a JPG to 500KB, or shrink a PNG for an online form, imageto10kb does it in seconds. Unlike a plain quality slider, it keeps testing settings until the file is at or just under 500KB, so you never guess or re-export. Because it runs in your browser, it even works offline once the page has loaded.
