JSK Photo Studio — Passport, Print & Merge av Tanay Roy

Make a passport or ID photo to an exact size, check it before you submit, and print a full sheet that measures right — all in your browser. Nothing is uploaded.

Most tools get the pixels right and the physical size wrong. JSK Photo Studio writes the real print resolution into the file, so a photo printed at 100% measures 35 x 45 mm against a ruler — not "about right".

FREE, AND IT WORKS WITHOUT AN ACCOUNT
Making a passport photo, checking it, building a print sheet and exporting a PDF all work with no sign-up, no watermark and no payment.

WHAT IT DOES
• 32 document sizes across 21 countries. Each links to the issuing authority's own published specification and shows the date we last checked it. Where we have not verified one ourselves, it says so plainly.
• A compliance check before you submit, not after you are rejected. Drag the crown and chin lines onto your head and it measures your actual head height against the document's published band, reporting numbers rather than a verdict.
• Print sheets that measure right. Tile one photo across A4, Letter, 4R, 5R, A5 or A6 with cut guides, and export a PDF whose page box is set in true millimetres. A printer calibration sheet handles the last half-millimetre.
• A scanner without a scanner. Photograph a document or ID card at an angle, drag four corners onto it, and get a square-on, straightened result. Photocopy mode flattens uneven lighting instead of turning shadows into black bars.
• Hit a kilobyte limit. A live file-size readout and a target band show whether your image fits the portal's limit while you move the quality slider.
• Merge and resize. Combine images into a grid, row or column, and resize to an exact size in pixels or millimetres at a chosen DPI.

NOTHING LEAVES YOUR DEVICE
No host permissions. No analytics, no tracking, no advertising. The extension asks for one permission — local storage — and requests no access to any website at all. The workspace shows a live network request counter, so you can check that claim rather than trust it.

WHAT NEEDS AN ACCOUNT
Nothing on the main path above. A free JSKAPPS account adds custom document sizes, per-photo selection and saved projects. A paid plan adds the photo editor, HEIC input from iPhones, and automatic file-size targeting.

Your photos are processed entirely on your own computer and are never uploaded.
