Frequently Asked Questions

How much can I reduce an image's file size?

Typical JPG files shrink 40–70% with minimal visible quality loss. PNG files with large flat-color areas can shrink even more. The exact amount depends on the original file and the compression level you choose.

Will compressing an image make it look blurry?

At moderate compression levels, the difference is rarely visible on screen. You can preview the compressed image before downloading and adjust the quality slider if you notice artifacts.

Does this tool support PNG transparency?

Yes. PNG files retain their transparent backgrounds after compression. If you need a transparent output, keep the format as PNG rather than converting to JPG.

Is there a file size limit?

Most images up to 20 MB are supported. For very large RAW or TIFF files, consider converting to JPG first.

Are my uploaded images kept private?

Your files are uploaded to a secure server solely for processing and are automatically deleted shortly after — they are never shared or stored long-term.
