Photo and Signature Size for Online Forms: Official Limits and How to Hit Them

What online forms usually ask for

Job, exam and admission portals in Pakistan and India mostly check the same few things when you upload a photo or signature:

• File format. Almost always JPG or JPEG. A PNG, HEIC or WebP file is often refused even when it looks fine.
• File size in KB. Either a maximum (for example "less than 30 KB") or a range with a minimum and a maximum (for example "10–20 KB"). Files outside the range are rejected automatically.
• Pixel dimensions or physical size. Some forms give exact pixels such as 200 × 230; others give centimetres such as 3.5 × 4.5 cm, or nothing at all.
• Background and framing. A recent colour photo, face clearly visible, against a white or light background. Signatures are usually dark ink on white paper.

More and more portals also ask you to take a live photo with your webcam or phone camera while you fill in the form. For those, you cannot upload a file you made earlier. You just need good light and a plain background.

Official photo and signature sizes (checked October 2026)

We only list bodies whose current rules we could read on their own website or official notice. Each row names the exact notice or guideline, because limits can differ between that body's exams.

We left out bodies whose current specifications we couldn't confirm on an official page, NTS among them. For those, use the size printed in the advertisement or on the upload screen.

How to hit an exact KB range

File size depends on pixel dimensions, JPG quality and how much detail is in the picture. To land inside a range:

1. Crop first. Cut away empty background with Crop Image so the bytes go into your face or signature. If the form gives pixels (for example IBPS's 200 × 230), set those in Resize Image.
2. Compress to the maximum. For a single limit, use a preset such as Compress Image to 20KB or Compress Image to 30KB. For other limits, enter your own target in Compress Image. PPSC's "less than 25 KB", for example, needs a target a little under 25.
3. Respect the minimum. For a range such as 20–50 KB, use Resize Image to 20KB to 50KB, which aims near the top of the range. You can change either limit.
4. Check the final number. The tools show the exact KB before you download. Aim a little inside the range rather than right on the edge, because portals can count kilobytes slightly differently.

If a photo is still under the minimum, raise the pixel size or start from the original camera image, not a copy that has already been compressed. If you have a PNG or iPhone photo, convert it to JPG first with PNG to JPG or HEIC to JPG.

Resizing a signature to the right pixels and KB

Sign on plain white paper with a dark pen (IBPS and UPSC both specify black ink), then photograph or scan it in good light. Open Signature Resizer. It crops tightly to the ink, turns grey paper white, and fits the signature into the pixel box you choose without stretching it.

• IBPS-style 140 × 60 px, 10–20 KB: start from Signature Resize 10 to 20 KB and change the pixel size to 140 × 60.
• SSC-style "about 6.0 × 2.0 cm", 10–20 KB: choose a custom size in cm with a DPI value, keep the range at 10–20 KB, and check that the result looks clear and not tiny. SSC rejects blurred or miniature signatures.
• Fixed 300 × 80 px: use Signature Resize 300×80.
• Only a maximum: use Resize Signature to 20KB or Resize Signature to 50KB. For a 20–50 KB range, use Signature Resize 20 to 50 KB.
• UPSC's three signatures: sign three times, one below the other, on the same sheet, and upload the whole block as one image. Don't cut out a single signature.

A clean, small signature can compress to fewer bytes than the minimum. The resizer first raises quality, and it can add padding so the file reaches the minimum without changing the picture.

Getting the photo right

For portals that accept an uploaded photo, start with a fresh, sharp picture taken facing the camera against a plain white or light wall, with even light and no shadows.

• Passport Size Photo Maker crops to 35 × 45 mm (413 × 531 px at 300 DPI) with face guides and can cap the file at 50, 100 or 200 KB. Passport Photo Under 50KB has that limit preset.
• If the form gives exact pixels, such as 200 × 230, crop to that shape with Crop Image, then resize and compress as described above.
• Keep your face large in the frame. NTA asks for the face to fill 80% of the photo with the ears visible.
• Don't swap backgrounds or retouch if the notice forbids altered photos. A photo taken against a plain wall is always the safer choice.

For live photo capture (SSC, UPSC, IBPS and NTA all use it), no file tool is involved. Sit facing a window or lamp in front of a plain light wall, remove caps and dark glasses, and fill the frame with your face and shoulders. Never point the camera at a printed photo. SSC says such applications will be rejected.

Everything in these tools runs in your browser, so your photo and signature are never uploaded to us.

Common reasons uploads get rejected

• Over the maximum or under the minimum KB. This is the most common reason, and the portal usually won't let you continue.
• Wrong format. PNG, HEIC or PDF uploaded where JPG/JPEG is required.
• Photo and signature swapped. A signature uploaded in the photo slot, or the other way round.
• Blurred, faint or miniature signature. Crop to the ink and keep it large in the frame.
• Signature in capital letters. IBPS does not accept these.
• Dark, patterned or coloured background, or shadows on the face.
• Caps, dark glasses, masks or hair over the eyes.
• Old or informal photos. A selfie, a group-photo crop or a photo that no longer looks like you.
• A photo of a photo in a live-capture step.
• Mismatch on exam day. IBPS warns that a signature on the attendance sheet that doesn't match the uploaded one can lead to disqualification. Sign the way you normally do.

Requirements change every cycle

The numbers in this guide come from the notices named in the table, and bodies revise them often. SSC, for example, now captures the photo live inside its application module instead of asking for an uploaded file.

Before you apply:

1. Open the current advertisement, notice or information bulletin for the exact post or exam.
2. Find the photo and signature section and note the format, the KB range, the pixel or cm size and the background colour.
3. Make your files to those numbers, and check the preview on the upload screen before you submit.

Keep the original, uncompressed photo and signature scan. Re-making a file from the original gives a better result than shrinking an already-compressed copy again.
