Exam Photo & Signature Resizer
Application portals each publish their own photo and signature rules. Pick the combination your form asks for, or type the exact numbers from its instruction page.
Read your own form before using any preset
The presets here reflect combinations that appear frequently — they are not official values. Requirements differ between boards, between exams run by the same board, and between years, and a preset that matched last year's notification may not match this one.
The instruction page or information bulletin attached to your application is the only authority. Take the KB range, the pixel dimensions and the format from it, type them into the boxes, and treat the presets as a starting point rather than an answer.
The three rules every portal checks
File size in kilobytes, with an upper limit and often a lower one. Pixel dimensions, sometimes exact, sometimes a range. Format, usually JPG. A file can satisfy two of the three and still be refused, which is why this tool applies all three in one pass.
Portals also add rules no resizer can help with — a photograph taken within the last three months, a plain light background, ears and both eyes visible, no cap or dark glasses, and on some forms the candidate's name and the date printed in a strip beneath the face. Those are photography and layout requirements. Fix them before you resize, because resizing a non-compliant photo only produces a smaller non-compliant photo.
Photo and signature are different jobs
A photograph carries continuous tone across every part of the frame and needs more bytes to stay natural. A signature is a few dark strokes on white and compresses to almost nothing. That is the whole reason photo allowances are typically 20–50 KB while signatures get 10–20 KB.
Process them separately: run the photo with its own numbers, download it, then the signature with its own. They occupy different upload fields on the form and are validated independently.
Thumb impressions
Several recruitment portals now ask for a left thumb impression alongside the photo and signature. The practical difficulties are different: ink coverage is uneven, the ridge pattern must stay visible, and heavy compression turns ridges into blotches.
Press the thumb onto a stamp pad, roll it slightly rather than pressing straight down, and take the impression on white paper. Crop to the print itself. Because ridge detail is fine-grained, give a thumb impression the larger end of whatever size range is permitted rather than the smallest file that passes.
Dimensions, ratio and cropping
When a form gives an exact pixel size, enter both numbers and the tool fits your whole image into that box. When it gives a ratio instead — 3.5:1 for a signature, 4:5 for a photo — crop the source to roughly that shape first, so the resize does not leave dead white space along one edge.
If the form states dimensions in millimetres, convert using the dpi it specifies: pixels = millimetres ÷ 25.4 × dpi. A 35 × 45 mm photograph at 200 dpi is 276 × 354 pixels.
If the upload still fails
Portals rarely tell you which rule failed, so check them in order of likelihood:
- Format is genuinely JPG, not a renamed PNG
- File size sits inside the range, including any minimum
- Pixel dimensions match the specification
- The limit applies per file, not to both files combined
- The photograph itself meets the background, recency and framing rules
- A different browser, if the portal is old and particular about what it accepts
Keep the original uncompressed files until the application is submitted and confirmed. If something is rejected you will want to start again from the full-quality source rather than from an already-compressed copy.
Before the deadline, not on it
Upload problems cluster in the final hours, partly because portals slow down under load and partly because a rejected upload leaves no time to re-take a photograph. Prepare the photo, signature and thumb impression as soon as the notification opens, check each one at 100% zoom, and keep the compliant files somewhere you can find them — most candidates apply to several exams in a season with near-identical requirements.
Questions
Which size does my exam need?
Take it from your own form’s instruction page. Common patterns are a 20–50 KB photo and a 10–20 KB signature in JPG, but boards change these and the published bulletin governs.
Can I resize photo and signature at the same time?
Process them one after another — the photo with its numbers, then the signature with its own. They are separate upload fields and are validated separately.
Does the tool crop my photo to the right shape?
It resizes to the dimensions you enter and fits the whole image in. Crop to head and shoulders first if the form expects portrait framing.
Is it safe to use for identity documents?
The image is processed in your browser and never transmitted or stored, which is a stronger privacy position than any tool that uploads to a server. Still be careful where you download files on a shared computer.
My form wants the name and date under the photo. Can this add that?
No. This tool resizes and compresses; it does not add text. Add the strip in any image editor first, then resize the finished image here.
How do I convert 35 × 45 mm into pixels?
Divide by 25.4 for inches and multiply by the stated dpi. At 200 dpi that is 276 × 354 pixels; at 300 dpi it is 413 × 531.
