Questions
Is my photo uploaded?
No. The image is resized and compressed inside your browser and never leaves your device, which matters for ID photos and signatures.
Can I compress a scanned certificate to 200 KB?
Yes, comfortably: 200 KB keeps a full page of normal print readable as a JPG. If the form wants a PDF instead, use Compress PDF to 200 KB.
The form also gives a size in pixels. Can I set that?
Yes. Enter the width and height under Exact size. The image is cropped from the centre to that shape rather than stretched, so a face or signature is never squashed.
How do I know which size my form wants?
The form’s instructions state it, usually as a maximum in KB and sometimes as width and height in pixels. Limits differ from one form to the next, so check yours rather than relying on a general rule.
Is 1 KB 1,000 or 1,024 bytes here?
We aim for 1,000. Forms disagree on which they mean, and a file under the 1,000-byte figure passes both kinds of check.
