Image files from modern smartphones routinely exceed 3–5 MB each. Our compression tool uses perceptual quality analysis to trim file weight by 60–80% while keeping the image visually indistinguishable from the original at typical viewing sizes. Smaller images load faster, use less mobile data, and pass platform upload limits.

When image compression solves a real problem

E-commerce sellers uploading product photos to Shopee, Lazada, or Etsy know that slow-loading images cost sales. Compressing product photos to under 200 KB maintains visual quality while dramatically improving page load times. WhatsApp compresses images automatically when you send them — but this can make them look worse. Compressing to 70–80% quality before sending gives you control over the output rather than letting WhatsApp choose. Web developers embedding images in Next.js, WordPress, or Wix projects compress assets to hit Core Web Vitals targets for Largest Contentful Paint. Google PageSpeed Insights frequently flags uncompressed images as a top performance issue.

How to use Compress Image — step by step

1

Upload the image

Drop a JPG, PNG, or WebP file. Up to 10 MB is accepted per image.

2

Set quality level

Use the quality slider (10–100%). 70–80% is the sweet spot — barely perceptible loss, significant size reduction.

3

Download the compressed image

The compressed file downloads in the same format. The download card shows the output file size.

Tips for best results

Product photos for Shopee/Lazada: target 100–300 KB at quality 75–80%.

Portfolio photos for personal websites: 200–500 KB at quality 80% balances quality and speed.

If you compress too aggressively (quality below 50%), JPEG artefacts become visible as blocky patches in smooth-colour regions.

PNG files with transparent backgrounds compress better with our Convert Image tool (convert to WebP) than with JPEG compression, which removes transparency.

Frequently Asked Questions

Does compressing at quality 80% look different from the original?

At quality 80%, the visual difference is imperceptible to most viewers at normal screen sizes. Differences only appear when zoomed in at 200% or more, which is not a normal viewing condition for web or social media images.

Why is my PNG barely smaller after compression?

PNG is a lossless format — it cannot be compressed the same way JPEG can. The PNG compressor reduces metadata and optimises the lossless encoding, but reductions are smaller (typically 5–30%). For large PNGs, converting to JPEG or WebP gives much better compression.

Is there a batch compression option?

Currently, one image is processed per upload. For multiple images, upload them one at a time or convert portfolio files to PDF first and use the Compress PDF tool.

Does quality 100% produce the same file as the original?

Not exactly. Quality 100 re-encodes the image at maximum JPEG quality, which may differ slightly from the original encoding. For a truly lossless result, use PNG format.

Can I compress an image that is already compressed?

Yes, but diminishing returns apply. A JPEG already at quality 70 compressed again at quality 70 will not shrink much further, and may introduce additional artefacts. Check whether the image is already adequately sized before compressing again.
