How do I resize a photo to 100 KB?
To resize a photo to 100 KB, upload it to FixDoks's photo resizer, crop the face, and download a JPG under 100 KB at 413 x 531 pixels, the standard 3.5 x 4.5 cm passport proportion at 300 DPI, or choose your own pixel size and minimum KB for your form.

How to use Resize Photo to 100 KB
- Pick the document tab (photo, signature and so on) and click Select to add a photo or scan from your phone or computer.
- Drag the crop box so the face or signature fills the frame. Signatures are cleaned and trimmed automatically.
- Click Resize. The file is made at the exact pixel size and inside the KB range, and downloads straight away.
- Repeat for each tab, then upload the files to the application form.
For forms with a 100 KB limit
University admission portals, state recruitment boards, scholarship schemes, visa appointment sites and many private job portals allow photos up to 100 KB. The extra room compared with 50 KB means you can keep a larger, sharper photo, which matters when the image is printed on an admit card, ID card or certificate.
Default size
The page starts at 413 × 531 pixels, which is 3.5 × 4.5 cm at 300 DPI, the standard passport photo proportion in India. At that size a photo fits comfortably under 100 KB at high quality. If your form states a different size, pick it from the preset list or type it in.
Can I set a minimum size?
The minimum is 0 KB by default. If your form says something like "between 50 KB and 100 KB", set the minimum to 50 and the tool will keep the file inside that band.
Photo or document?
This tool is designed for face photos, with a face guide in the crop box. For scanned certificates, mark sheets or ID cards that must be under 100 KB, use compress image to 100 KB, which keeps the whole document and adjusts the pixel size automatically.
Tips
- Start from the original photo, not a WhatsApp forwarded copy, which has already lost quality.
- Crop so the head and top of the shoulders fill the frame.
- Use a plain light background. The Make background white button replaces a cluttered one when available.
- Name the file sensibly before uploading if the form shows file names, for example with your application number.
Photo checklist
- Recent colour photo with a neutral expression, eyes open and looking at the camera.
- Even lighting with no harsh shadows across the face or on the wall behind.
- Plain, light background. White is the safest choice for government forms.
- No caps or sunglasses. Normal glasses are allowed on many forms, but some ask you to remove them to avoid glare.
How the KB target is met
The tool encodes the cropped photo at the highest JPG quality that stays under the maximum. It checks the real file size after each attempt instead of guessing, so the final file is as sharp as the limit allows. Because it counts 1 KB as 1,000 bytes for the maximum, the file passes portals that use either definition of a kilobyte.
Different size on each form?
Keep your original photo safe and come back to this page for each new form. It takes a few seconds to make a new version at a different size, and you avoid the quality loss of shrinking an already compressed file again and again.
