Exam photograph and signature upload specifications

12 exams · records read on 2026-07-29 · rendered for people at Exam photo & signature specs

GET https://www.altftool.com/api/open-data/exam-photo-specs

One record per exam. Each carries the photograph mode, every uploadable asset with its KB range, pixel or physical dimensions and DPI where the body prints one, the background and face-coverage rules, and the notification the whole record was read out of.

Attribution for this dataset

Link to the record's page_url:

<a href="https://www.altftool.com/exam-photo/ssc-cgl">Source: AltFTool</a>

Fields on each record

slug

Stable identifier. Also the last segment of page_url.

name / full_name

Short exam name, and the full title the notification uses.

conducting_body / portal

Who runs the exam, and the portal applications are filed on.

page_url

The AltFTool page this record describes. This is the link attribution has to point at.

photo_mode

"upload" (a photo file is uploaded), "live-capture" (no photo file at all — the form takes the photograph) or "upload+live" (both).

photo_note / photo_age_rule

How the photograph is captured, and any cut-off date after which it must have been taken. Absent when the document sets none.

name_or_date_on_photo

Whether the body wants the candidate's name and date printed on the image. Several forbid it outright.

background

The background, dress and face-visibility rules as printed.

aadhaar_note

SSC only: the concession for candidates who opt for Aadhaar authentication.

assets[]

id, label, format, min_kb, max_kb, pixels {width,height}, pixels_are_minimum, stated_pixels, long_edge_px, physical {width,height,unit}, dpi, notes[]. Keys are omitted rather than nulled when the document does not print that figure.

extras[]

Rules that sit outside the upload boxes — printed copies to carry, certificates uploaded as PDFs.

source

document, issued, url, confidence, confidence_label, read_on, and note where a qualification applies. Never absent.

Limitations you must read before republishing

• Every figure below was read out of the document named in that record's `source` block, on 2026-07-29. It is a dated fact about that document — "this is what the notification said when it was read" — not a live feed from the conducting body.
• Exam bodies revise these specs every cycle. Before you act on a number, and before you republish it, open `source.url` and check it against the notification for the cycle your reader is actually applying for.
• Some records describe the most recent notification a body had published rather than the cycle now open. Where that is true the record says so in `source.note`, and that note has to travel with the figures.
• Confidence is per record, in `source.confidence`. Anything other than `primary` was not read from that exam's own PDF — see `confidence_levels`.
• 4 of these exams no longer accept a photograph file at all (`photo_mode: "live-capture"`): SSC CGL, SSC CHSL, SSC GD Constable, RRB NTPC. They capture the photograph inside the application form, so there is no KB limit and no pixel size for it. Widely copied photo figures for those exams describe a step the form no longer has.
• Where an official document contradicts itself, both figures are kept in the asset `notes` rather than one being silently chosen. Do not drop those notes — the contradiction is in the source, not in this dataset.
• AltFTool is not a conducting body, a government department, or an authority on any exam's rules. It is a tools site that opened the notifications and wrote down what they say.

What source.confidence means

primary

The figures were extracted from the conducting body's own PDF for this exam.

derived

The exam's own PDF was not readable. The upload block was read from a sibling notice of the same cycle from the same body, where that block is boilerplate.

unconfirmed

Only secondary listings were reachable. The number is reported as-published elsewhere and is flagged as unconfirmed on the exam page too.

Format converter index

64 converters · rendered for people at Transform

GET https://www.altftool.com/api/open-data/transform-converters

One record per converter page, with the format pair it handles. Build a directory, a "convert X to Y" lookup, or a link map from it. Build-system internals — engine, library, status — are deliberately not served.

Attribution for this dataset

Link to the record's url:

<a href="https://www.altftool.com/transform/svg-to-jsx">Source: AltFTool</a>

Fields on each record

slug

Stable identifier. Not reliably {from}-to-{to} — use url.

title

The converter's display name.

category

The format family it is grouped under.

from / to

The format pair, as AltFTool identifies formats. Not MIME types.

url

The converter's page. This is the link attribution has to point at.

Limitations you must read before republishing

• This is an index of converter pages, not a conversion API. There is no public endpoint that converts a file; each converter runs on its own page.
• Slugs are not reliably `{from}-to-{to}`: 45 of the 64 do not follow that shape. Use the `url` field on the record instead of composing one.
• `from` and `to` are the format identifiers AltFTool groups converters by. They are not MIME types and not guaranteed file extensions.
• Converters are added and retired. Treat a response as a snapshot and re-fetch rather than hardcoding the list.

Fetching it

Nothing to configure. Both responses are pretty-printed so you can open them in a browser tab and read the provenance before you decide to trust them.

curl -s https://www.altftool.com/api/open-data/exam-photo-specs | jq '.records[0].source'

fetch("https://www.altftool.com/api/open-data/transform-converters")
  .then((response) => response.json())
  .then(({ records }) => console.log(records.length));

• Methods: GET only. Nothing here is writable.
• Cross-origin: open to any origin, so browser-side fetch works from your own pages.
• Freshness: regenerated daily. There is no push notification and no webhook — re-fetch on your own schedule.
• Stability: fields are added rather than renamed where possible, and keys are omitted rather than set to null when a source document does not print that figure. Read defensively anyway.

What this is not

• Not a conversion API. The converter index lists pages. There is no endpoint that accepts a file and returns a converted one.
• Not an authority on any exam. AltFTool is a tools site. The conducting body named in each record's source.document is the authority; open that document before you act on a figure.
• Not a live feed. Exam records are a dated reading of a named notification, stamped in source.read_on.

Corrections, and asking for more

If a figure is wrong, or a notification has been superseded, tell us and it gets fixed at the source — the pages and both endpoints are generated from the same records, so one correction lands everywhere. If you want a dataset published that is not here yet, say which one and what you would do with it. Contact us. Media and brand enquiries belong on the press page.
