ID Photo Resizer - Crop & Resize to Official Specs (Local)

1. Produce a standards-sized photo

Default export leans JPG because most registration portals reject PNG silently or rename-reject. JPEG quality defaults near 0.92; lower it when a ~200KB ceiling appears in the instructions. PNG remains available for lossless handoff into print-layout or further editing.

1. Upload a frontal portrait. Plain backgrounds segment more reliably; convert HEIC to JPG first if the browser cannot decode the phone format.
2. Select a target spec — buttons show name, pixels, and millimeter hints. Deep links from the size guide (?spec=) preselect the same PHOTO_SIZES entry so you do not guess which row matches the form.
3. Choose background (or enable Skip cutout when the background is already correct), adjust the vertical nudge if headroom is tight, set JPG/PNG and JPEG quality, then export and read the result strip.

2. Cover crop and vertical nudge — no stretch

The crop locks to the target aspect ratio and never stretches the face. Framing starts centered; use the vertical nudge when the crown is clipped or the chin sits too high. If the subject hugs the edge of the original frame, recompose or reshoot — forcing a crop from a bad capture still fails portal review even when pixels match. Skip cutout skips the segmenter load and only crops/resizes — faster when the background already matches the requirement.

• Most registration portals ask for JPG; start around 90–92% quality, then lower if the KB strip exceeds the portal limit.
• Process one photo at a time when framing quality matters more than throughput.
• Match the exact PHOTO_SIZES name from the form (for example 申根签证 vs a generic 35×45mm guess).

3. What this page does not certify

Pixel size and a solid background are necessary but not sufficient. Issuing authorities still judge head proportion, expression, attire, glasses glare, and ear visibility. This tool does not replace official acceptance. Use the compliance-check sibling for a local pre-screen of size, brightness, background uniformity, and file-size bands — still advisory, not a government verdict. Dress code and expression remain your checklist, not the exporter’s.

4. Failure samples you can reproduce

• Undersized upload upscaled only by stretch tools elsewhere → soft faces; here we cover-crop to exact pixels from a sharp enough source instead of inventing detail.
• Busy bookshelf background with hair the same color as the wall → ragged masks; reshoot against a plain wall or fix background in the dedicated background tool first.
• Export PNG for a portal that only accepts JPG → upload rejected; switch format here rather than renaming the extension.
• Headroom too tight after crop → nudge vertically; if the slider cannot recover, the source framing is too tight — crop wider in camera.

5. Privacy and local processing

Segmentation uses an on-device model path; your portrait is not sent as upload payload for conversion. First-time model load may download runtime assets that then cache. Shared computers still retain Downloads and blob previews — delete exports you do not need. Do not paste ID photos into public tickets or group chats.

6. Handoff and print next steps

When someone else will submit the file, note the spec name, pixel size, whether cutout was skipped, and JPEG quality. For home printing of multiple copies, use the A4 print-layout sibling after the background and framing look right. Keep the original camera file until the application portal accepts the derivative.

1. Confirm result strip pixels match the chosen PHOTO_SIZES row.
2. Open the download on a phone screen — desktop zoom lies about skin texture.
3. If a portal rejects file size, adjust JPEG quality here or compress without changing crop.
4. If background color is wrong, fix it here or in the background tool before print layout.
