Job portals, university admissions, visa applications and government forms often say: "Photo must be JPG, maximum 100 KB". A photo straight from a phone camera is usually 2 to 5 MB, so the upload fails. Here is how to shrink it without making it blurry.
Why phone photos are so large
A modern phone takes photos of 12 megapixels or more, around 4000 × 3000 pixels. A form that shows your photo in a small box needs only a fraction of that. File size depends on two things you can change: the number of pixels (dimensions) and the compression (JPG quality).
The quick method: compress to a target size
- Open the image compressor and choose your photo.
- Under Compression, choose "Make each image smaller than" and type the limit from the form, for example 100 KB. Aim a little below it (say 95 KB) to be safe.
- Keep the output as JPG unless the form asks for PNG.
- Download and upload. The tool finds the best quality that still fits under the limit.
If the photo still looks blurry: reduce the dimensions first
Squeezing a 4000-pixel photo into 50 KB forces heavy compression, which causes blur and blocky patches. Shrinking the dimensions first gives a much sharper result at the same file size. For most forms, 600 to 800 pixels on the longest side is plenty for a face photo, and 1200 to 1600 pixels for a document scan. Set this with Maximum width/height in the compressor, or use the image resizer for an exact size.
Typical limits and what to aim for
| What you are uploading | Typical limit | Good dimensions |
|---|---|---|
| Passport-style photo on a form | 20 – 100 KB | About 400 × 500 px |
| Signature | 10 – 50 KB | About 300 × 80 px |
| CNIC, certificate or degree scan (image) | 100 – 500 KB | 1200 – 1600 px on the long side |
| Several pages of documents | 1 – 2 MB as one PDF | Compress each image, then combine |
For several pages, compress the images first and then combine them with JPG to PDF.
Passport and visa photo sizes
Printed ID photos are measured in millimetres. To print sharply they need about 300 pixels per inch, which gives these pixel sizes:
| Photo | Size | Pixels at 300 dpi |
|---|---|---|
| Passport / ID (Pakistan, India, UK, EU, Saudi, UAE…) | 35 × 45 mm | 413 × 531 px |
| US passport / visa | 50.8 × 50.8 mm | 600 × 600 px |
| Canada passport | 50 × 70 mm | 591 × 827 px |
| Malaysia passport | 35 × 50 mm | 413 × 591 px |
| China visa | 33 × 48 mm | 390 × 567 px |
The resizer crops your photo to the right shape from the centre. Before you print, check the current rules of the office you are applying to: background colour, face size and whether glasses are allowed change from time to time.
Tips for a sharp, accepted photo
- Take the photo in daylight facing a window, against a plain white or light wall.
- Crop to the required shape before compressing, so no pixels are wasted on background.
- Don't compress the same file again and again; start from the original each time.
- Check the file name and format the form expects (.jpg or .jpeg, not .heic from iPhones).
