How to scan A4 document with Pixfit
Four steps, entirely in your browser. Your photo never leaves your device.

Pick output mode + watermark

Export as A4 / Letter / A5 PDF
Pack both sides onto a single sheet with cut marks, and download as PDF or PNG. The file is generated locally — no upload required.
A4 document — frequently asked questions
Is scanning A4 document in Pixfit free?
Yes. Pixfit's ID Document Scanner is free with no watermark on the workspace, no signup, and no monthly cap. The optional anti-misuse watermark on the output is off by default — you decide whether to turn it on.
Will the A4 document photo be uploaded to a server?
No. Perspective correction, watermark compositing, and PDF assembly all run locally in your browser. The phone-shot photo of A4 document never leaves your device.
Can I add an anti-misuse watermark to A4 document?
Yes, it's optional and off by default. When you turn it on, the text and opacity are fully customisable (opacity clamps to 30 %–70 % so the watermark stays visible enough to be useful) — handy when you want to mark the scan as 'For XYZ Company onboarding only' before sending.
Will the scan of A4 document be accepted by official portals?
Most online submission portals accept rectified phone-camera scans of A4 document, and the output mimics a flatbed scanner closely. For high-stakes filings, check the destination portal's exact spec — file size, DPI, color or black-and-white — and pick the matching output mode before exporting.
