## What is Passport Signature Resizer?

Passport Signature Resizer is a free Farvixo tool that lets you resize signature to passport upload specifications. It applies the issuing authority's published rules for pixel dimensions, file size, DPI and background, so the file is accepted the first time. Identity documents are processed entirely in your browser and are never uploaded anywhere.

## How to use Passport Signature Resizer

1. **Upload your photo or document** — Add your file to Passport Signature Resizer. It is processed entirely in your browser — important for identity documents, which never reach a server here.
2. **Pick the official specification** — Choose the form or authority you are applying to. Passport Signature Resizer applies that body's exact rules for dimensions, file size, background and DPI, so you are not guessing at the requirements.
3. **Download the compliant file** — Save a file that already matches the upload specification, ready to submit without rejection for the wrong size or format.

## Use cases

- Applying online where the portal rejects photos for being the wrong size or file weight
- Preparing photo and signature files for an exam registration before the deadline
- Anyone who does not want an identity document passing through a third-party server
- Fixing a submission that was already rejected for a specification mismatch

## Tips

- Photograph against a plain light background in even daylight — no flash shadow behind the head.
- Confirm the specification against the portal you are actually applying on; requirements differ between authorities and occasionally change.
- Keep the compliant output file. Most applications ask for the same photo again at a later stage.

## Common problems

- **The portal rejected the file for size** — Portals enforce both pixel dimensions and a KB range. Select the exact portal preset rather than a generic resize, so both limits are met at once.
- **The face is cropped wrongly** — Official specs fix the proportion of the frame the head must occupy. Re-upload a photo taken further back so there is room to crop correctly.
- **The background is not accepted** — Shadows and off-white walls fail an automated background check. Re-shoot against a plain white or light-grey surface with even lighting.

## FAQ

### Why does the portal reject my signature?

Dimensions and file size are enforced together, and meeting one while missing the other fails. A grey or off-white background is the other frequent cause — portals expect white, and uneven lighting on the paper produces grey.

### How should I capture my signature?

Sign in black or dark blue ink on plain white paper, then scan or photograph it flat under even, indirect light. A shadow across the page is what produces the grey box that gets rejected.

### Can I sign digitally instead of on paper?

A signature drawn on a touchscreen is usually accepted, and gives you a clean white background automatically. Check that your specific application permits it — some require a scan of a physical signature.

### Is my signature uploaded anywhere?

No. Everything runs in your browser. A signature is a sensitive thing to hand to a third-party server, and this tool exists so you do not have to.

### Should I keep the resized signature?

Yes. The same signature is usually requested again at appointment or verification stage, and having the compliant version saved avoids repeating the process under deadline.
