Reduce file size while maintaining quality

How to Compress Images Correctly

Smaller images are easier to upload, email, and use on websites. The quality slider helps you choose between a smaller file and a clearer picture.

Pro Tips:

  • Good starting point: Try 70% to 80%, then compare the preview before downloading.

  • Format Choice: This compressor exports JPEG output, which is usually best for photos and not for transparent graphics.

  • Same image set: Reuse the same quality setting across similar images to keep a consistent look.

Common Questions

Is the compression safe?

Yes. The tool creates a smaller download and does not replace your original image.

Will I lose visual quality?

Compression can reduce quality, especially at low settings. Use the preview and avoid very low quality values unless a tiny file is more important than detail.

Can I compress PNGs?

You can upload common image formats, but this compressor exports JPEG. Use the converter when you need PNG or WebP output.

Mistakes to avoid

Final checks

  • Open the download and make sure logos, labels, and edges still look clean.

Questions

Frequently asked questions

How much can I reduce an image size?

It depends on the original format, dimensions, and quality setting. Photos usually compress more than flat graphics or already-optimized files.

Why does the compressed image look different?

Lower quality settings can remove small details to reduce file size. Use the preview and raise the quality if the image looks too soft.

Will compression damage my original file?

No. The original stays on your device, and the compressed image is downloaded as a new file.
