Quick answer
Pixel size controls image dimensions; KB size controls file weight.
Some forms ask for width and height in pixels, not just KB size. Set dimensions first, then compress if needed.
Pixel size and KB size are different
Pixel size means the image width and height, such as 300 × 400 px. KB size means how heavy the file is. An image can have correct pixels but still be too large in KB.
For online applications, read the instructions carefully. Some portals mention both dimensions and file size.
- Width and height control image dimensions.
- KB controls file size.
- Set pixels before final compression.
- Always check both values before upload.
When forms ask for width and height
Pixel-based resizing is common for photos, signatures, ID uploads, student forms, job applications and admission portals.
- Profile photo dimensions.
- Signature image dimensions.
- Document image width or height.
- Square photo upload requirements.
