Frequently asked questions

Which size should I choose for my form?

Always use the exact numbers printed in your application's instructions or official notification — pixels or cm, DPI, minimum and maximum KB, and format. The presets here are only common examples.

Can I convert an iPhone (HEIC) photo?

Yes — HEIC photos are converted automatically and saved as JPG.

Is my photo uploaded anywhere?

No. The image is resized inside your browser and never leaves your device — important for ID photos and signatures.
