How much can images be reduced in size?

Typical compression reduces file size by 60-80% at the default 80% quality setting. Results vary based on the image content — photos with complex details compress less than simple graphics.

Is it really free and private?

Yes. All compression runs in your browser using JavaScript. No images are uploaded to any server. There are no usage limits, no sign-up, and no watermarks.

Will compression reduce image quality?

At the default 80% quality setting, compression is virtually imperceptible. You can preview the before/after comparison side by side before downloading. Lower quality settings will show more artifacts but produce smaller files.

How many images can I compress at once?

You can batch compress up to 10 images at once. Each image can be up to 50 MB. For larger batches, simply run the tool multiple times — there are no daily limits.

Does it work on mobile devices?

Yes. The tool runs in any modern browser including Safari on iOS and Chrome on Android. You can compress photos directly from your camera roll without installing any app.

Can I also resize images while compressing?

Yes. Use the Max Width slider to set a maximum dimension (320px to 4096px). Images larger than this width will be proportionally resized. Combined with quality adjustment, this gives you full control over the final file size.

Q: What image formats can I compress?

You can compress JPEG, PNG, WebP, and BMP images. The compressed output preserves the original format, so a JPEG input produces a compressed JPEG output.

Compress JPEG, PNG, and WebP images directly in your browser. No upload to servers, no sign-up — your files stay private. Adjust quality, resize, and batch process up to 10 images at once.
