When do you need a 500KB image?

A modern phone photo is often 4–8MB. Bringing it down to 500KB removes almost all of that weight while keeping a full-resolution look, which makes it ideal for email attachments and CMS uploads.

How to compress an image to 500KB

  1. 1. Add your images

    Drag and drop JPG, PNG, WEBP, HEIC, GIF, BMP or AVIF files — or select them from your device. Nothing is uploaded.

  2. 2. Set the target size

    Pick 500KB or type your own limit. Advanced options let you set dimensions, format and quality priority.

  3. 3. Download the result

    Every file shows its before and after size. Download them individually or grab a ZIP of the whole batch.

Why this compressor actually reaches your limit

Exact target file size

Say “200KB” instead of guessing a quality percentage. A binary search finds the highest quality that still fits your limit.

Batch compression

Add up to 30 images, optimize them in one run, and download everything as a single ZIP archive.

100% private

Images are decoded and re-encoded on your own device with the Canvas API. Nothing is uploaded to any server.

Automatic resizing

When quality reduction alone cannot reach the target, pixel dimensions are reduced step by step until it fits.

Need a different file size?

Every size below uses the same optimizer with a different preset target.

Your images never leave your device

Compression runs in a Web Worker inside your browser using the HTML5 Canvas API. There is no upload step, no temporary storage and no server-side copy — which is exactly why passport photos, ID scans and exam documents are safe to process here. Read the privacy policy.

Frequently asked questions

Will a 500KB photo still be full resolution?

In most cases yes. At 500KB the optimizer can usually reach the target with quality reduction alone, so the original pixel dimensions are preserved.
