What is the Photo & Signature Resizer?
Many exam boards, university applications, and government portals require a photo or signature scan to be an exact pixel size and under a maximum file size in KB — a combination that's fiddly to hit by hand. This tool crops to your exact target dimensions, then automatically finds the highest JPEG quality that still comes in under your size limit, so you get a result that meets both requirements in one step.
How to Resize a Photo or Signature — Step by Step
- Upload your photo or signature. Drag and drop one or more images into the box above.
- Pick a preset or enter custom values. Choose the Photo or Signature preset, or set your own width, height, and max size in KB.
- Resize and download. Click "Resize" — the result is cropped and compressed to fit your requirements.

Frequently Asked Questions
What if my exam form needs different dimensions than the presets?▾
Enter your own width, height, and max size in KB — the presets are just a shortcut for the most common requirements.
Will my photo be cropped or stretched?▾
The image is cropped (not stretched) to exactly fill the target dimensions, so proportions stay natural — center your subject before uploading for the best result.
What if the size limit is too small for any reasonable quality?▾
The tool always returns its best attempt at the lowest usable quality rather than failing outright, though extremely small size limits may show visible compression.
