Short answer: Pick your photo or signature, choose PPSC (under 25 KB), FPSC (under 30 KB) or your own width, height and KB limit, and download a JPG the form will accept. It works on any phone. Everything happens inside your phone’s browser, so your picture is never uploaded to any server. PPSC and FPSC only publish a KB limit and a format, not pixel sizes, so the tool keeps your crop and reduces the file just enough to pass.
Key takeaways
- FPSC asks for a passport size picture in JPG or JPEG, less than 30 KB.
- PPSC’s online guidelines ask for a JPG picture less than 25 KB.
- NTS, HEC and the passport e-Services set limits in megabytes, so size is rarely the problem there; background and clarity are.
- None of the commissions I checked publish a signature size, so use the Custom option with the limit your form shows.
- A white background, even light and a sharp face matter more than the exact number of pixels.
- Your files stay on your device: the resizer works offline once the page has loaded.
How to use the photo and signature resizer on your phone
I built this for the students and job seekers who follow my YouTube channel, so it works on an ordinary phone with no app. Most phone photos are 2 to 5 MB, about 100 times bigger than a 25 KB limit. Here is the quickest way to get a file the portal accepts.
- Tap Choose photo. On Android you can pick from the gallery or take a new picture; on iPhone you can pick from Photos or Files. Whatever the input (JPG, PNG or an iPhone photo), the download is always a JPG.
- Pick a preset from the list (PPSC photo, FPSC photo, NTS, passport, NADRA Pak-ID or HEC), or choose Custom and type the width, height and maximum KB your form asks for.
- Drag the crop box so your head and the top of your shoulders fill the frame. For a signature, crop tightly around the signature with a little white space on every side.
- Tap Resize. The tool shows the final size in KB and the pixel dimensions, and a preview at full size so you can check that your face or signature is still sharp.
- Tap Download JPG. The file lands in your Downloads folder (Android) or Files app (iPhone), ready to upload in the form.
The tool counts 1 KB as 1,000 bytes, which is a little stricter than the 1,024 bytes some portals use. Where the official text says “less than”, it aims one KB below the limit. So a file that says 24 KB here will not be refused by a form that wants less than 25 KB.
Official photo and signature requirements in Pakistan (checked November 2026)
I read each body’s own guidelines, manuals and portal pages and only used numbers they publish themselves. Where a body does not publish a number, the table says so, and there is no preset for it.
| Form | Photo size limit | Pixels | Format | Background | Source |
|---|---|---|---|---|---|
| PPSC online application | Less than 25 KB | Not published | JPG or JPEG | Not stated | PPSC |
| FPSC general recruitment | Less than 30 KB | Not published | JPG or JPEG | Not stated (no informal pictures) | FPSC guidelines |
| NTS candidate portal | Up to 5 MB | Not published | Not stated | White or blue | NTS manual |
| Online passport (DGIP e-Services, new categories) | Not more than 3 MB | 350 x 467 | JPEG or JPG | White | DGIP |
| NADRA Pak-ID online | Up to 60 KB | Not published (45 x 35 mm) | Not stated | Plain white | NADRA |
| HEC e-Services profile | Not over 15 MB | Not published | PNG or JPG | Plain blue or white | HEC |
| SPSC | Not published | Not published | Digital photo | White | SPSC |
| KPPSC, BPSC, ETEA | Not published | Not published | Not stated | Not stated | Check the advertisement |
A few notes on this table. The FPSC figure comes from its guidelines updated in September 2025, which say the picture “must be less than 30 KB and in jpeg format only”. The PPSC figure comes from two of PPSC’s own guideline pages; PPSC’s site often refuses connections from outside Pakistan, so if you are in Pakistan, open the current advertisement and check its “Photograph and CNIC picture requirements” section too. The passport rule of 350 x 467 pixels is listed by the DGIP for the online passport categories such as newborn and reprint; the separate renewal portal shows its own instructions when you upload. NADRA’s Pak-ID guidelines also ask that your face fills 70 to 80% of the photo and that you remove glasses.
Signature size: none of PPSC, FPSC, NTS, KPPSC, SPSC, BPSC, ETEA, DGIP, NADRA or HEC publishes a signature pixel or KB limit in the guidelines I could read. Some resizer websites list “140 x 60 pixels, 10 to 20 KB” for signatures; that matches common Indian exam rules, not any PPSC or FPSC document I could find. If your form asks for a signature, use the Custom option with the numbers shown on the upload screen.
How to take a good photo at home
You do not need a studio. A rejected photo is usually a light or background problem, not a camera problem, and both are easy to fix at home.
- Background: stand about one metre in front of a plain white wall or a white bedsheet pinned flat. A gap between you and the wall removes most shadows.
- Light: face a window in daytime. Avoid the ceiling light alone, which puts shadows under the eyes, and avoid flash, which causes shine and red eye.
- Camera: ask someone to hold the phone at your eye level, about one metre away, using the back camera. Do not use beauty filters or portrait blur.
- Pose: look straight at the camera, mouth closed, both ears and both edges of the face visible. NADRA’s guidelines allow head coverings such as a hijab if the face from chin to forehead and both edges of the face are clearly visible. Remove glasses.
- Clothes: formal and darker than the background, so the outline is clear. FPSC specifically warns against informal pictures.
How to make a clean signature image
- Sign on plain white A4 paper, not lined notebook paper. Lines and grid marks show up in the scan.
- Use a black or dark blue ballpoint or gel pen and sign a little larger than usual. Thin, light strokes can disappear when the file is compressed to a few KB.
- Put the paper on a table near a window, hold the phone straight above it (not at an angle) and make sure your hand or phone does not cast a shadow.
- Sign exactly as on your CNIC. The signature on the application is compared with your documents later.
- In the tool, crop close to the signature and choose Custom. Turn on Clean background: it raises the contrast so the paper turns pure white and the ink stays dark, which also makes the file much smaller.
How to reduce image size to 20 KB, 50 KB or 100 KB without losing clarity
File size in KB depends on three things: the number of pixels, the JPG quality setting, and how much detail the picture has. A busy background full of texture takes far more KB than a plain white one. That is why a clean background helps you twice: it is what commissions want, and it compresses well.
Resize first, then compress
Squeezing a 12 megapixel photo to 20 KB only by lowering quality gives a blocky, smeared face. Reducing the dimensions first keeps it sharp. This tool does both steps in that order: it reduces the pixels only as far as needed, then searches for the highest JPG quality that still fits under your limit.
Targets that come up most
- 20 KB: fine for a signature, and possible for a face photo with a plain background. Choose Custom, enter 20 in the KB box and leave width and height empty so the tool picks them.
- 25 to 30 KB (PPSC, FPSC): use the preset. The tool keeps a margin below the limit.
- 50 KB and 60 KB (NADRA): enough for a sharp passport style face. Use the NADRA preset for Pak-ID.
- 100 KB: generous for most forms. Use it when a university or private employer asks for “under 100 KB”.
If the tool says it cannot reach your target, the width and height are too large for that KB limit. Lower them, or crop tighter so there is less background.
A plain white background and window light do more for a passing photo than any app: they look right to the commission and shrink to 25 KB easily.
Common reasons a photo or signature is rejected
- File too big: even 26 KB fails a “less than 25 KB” check. Use the preset, which aims below the limit.
- Wrong format: PNG, HEIC, WEBP or PDF uploaded where JPG is required. Renaming a file to .jpg does not convert it; this tool always saves a real JPG.
- Informal or old photo: selfies, group photo crops, sunglasses or a photo many years old.
- Coloured or patterned background where white is asked (SPSC, NADRA, passport).
- Blurred or too dark: usually from compressing a large photo too hard, or from taking it at night.
- Signature unreadable: too faint, cut off at the edges, or photographed on lined paper.
- Photo and signature swapped in the two upload boxes.
Once you submit, some portals do not let you change the photo. NTS, for example, allows you to update a submitted application only once. Check the preview on the form before you tap Submit.
Privacy: your photo never leaves your phone
Many free resizers upload your picture to their server, and your photo, signature and CNIC are exactly the files you should not hand to unknown websites. This tool uses your browser’s own canvas feature: the image is read, resized and saved on your device, and nothing is sent to ismailblogger.com or anyone else. You can even switch on airplane mode after the page loads and it still works.
The same care applies to the rest of your application. Pay fees only through the official PSID or challan, never to agents who promise a “confirmed” seat. If you are building income online while you prepare for tests, my guide to online earning in Pakistan lists methods that do not need any upfront fee, and you can find more free calculators on the ismailblogger tools page.
Frequently asked questions
How do I resize an image to 20 KB?
Open the tool, choose your photo, select Custom and type 20 in the maximum KB box. Leave width and height empty and tap Resize. The tool lowers the pixels and the JPG quality until the file is under 20 KB, then shows you the result before you download it.
What is the PPSC picture size?
PPSC’s online application guidelines ask for a recent passport size picture in JPG format, less than 25 KB. PPSC does not publish pixel dimensions there, so any passport style crop is fine as long as the face is clear. Check the current advertisement as well, because each one has its own photo section.
Is there a PPSC image size reducer that works on mobile?
Yes, this page. Choose the PPSC photo preset and the tool gives you a JPG of about 24 KB or less, which fits the “less than 25 KB” rule. It runs in Chrome or Safari without installing an app.
What is the FPSC photo size?
FPSC asks for a passport size picture in JPG or JPEG format, less than 30 KB, and warns against informal pictures. Its guidelines do not give pixel dimensions or a background colour, but a white or light plain background is the safe choice.
What size should my signature be?
Use whatever the upload screen of your form says. None of the Pakistani commissions I checked publishes a signature size in its guidelines. If the form shows something like “10 to 20 KB” or fixed pixels, enter those numbers in Custom; the tool resizes the signature to match.
What is the NTS photo size?
The NTS candidate portal manual asks for a passport size profile photo with a blue or white background and allows images up to 5 MB. Some NTS projects set their own rules in the advertisement, so read that too.
Will my photo lose quality when reduced to a few KB?
Some fine detail goes, but the face stays clear if you crop tightly and use a plain background. Zoom into the preview before downloading.
Is it safe to resize my CNIC picture or signature here?
Yes. The file is processed only in your browser and is not uploaded or stored anywhere. Close the tab and it is gone from the page.
How do I resize a signature to 10 to 20 KB?
Sign on plain white paper, take a straight photo, then choose Custom, crop close to the signature, turn on Clean background and type 20 in the maximum KB box. The tool keeps the file under 20 KB. None of the Pakistani commissions I checked publishes a signature size, so use the numbers your form’s upload screen shows.
What is the NADRA Pak-ID photo size?
NADRA’s Pak-ID guidelines ask for a photo of up to 60 KB on a plain white background, 45 mm high by 35 mm wide, with your face filling 70 to 80% of the picture. Choose the NADRA preset.
The presets on this page follow the official guidelines of PPSC, FPSC (updated September 2025), the NTS candidate portal manual, DGIP e-Services, NADRA’s Pak-ID photo guidelines and HEC e-Services, last checked 10 November 2026. Requirements can change in each advertisement, and the advertisement or the form’s upload screen always takes priority. Check the official advertisement for your post before you upload, and contact the commission if your file is still refused.
