Tips for a file that gets accepted

Frequently asked questions

How do I reduce image size to 100 KB?

Select the image above and press "Resize and check KB". The tool lowers JPEG quality and, only if needed, the pixels until the file is 100 KB or less.

Will the image shape change?

No, the default preset keeps your original shape. Only the passport, signature and declaration presets use fixed pixels.

Is there a file size limit for the original?

Very large photos (above about 40 megapixels) may be slow on old phones; otherwise any normal phone photo works.

Can I convert PNG to JPG under 100 KB?

Yes. PNG and WebP are accepted and the download is always a JPG.
