How to resize image to 20 KB
- Choose or drop your photo, signature or scan.
- Keep 20 KB, or enter the size and dimensions from your form's instructions.
- Download the resized JPG and upload it to the form.
Who needs an image under 20 KB?
Signatures and passport-style photos on exam, recruitment and scholarship application forms — one of the most common upload limits.
Tips for the best result at 20 KB
- Set the exact pixel dimensions from the form first, then the size limit.
- Use a plain, light background — busy backgrounds take more bytes.
- If the form also has a minimum (e.g. 10–20 KB), enter it under “Min size”.
How it hits 20 KB
We binary-search JPEG quality at your chosen dimensions and keep the best quality that is still under 20 KB. If even low quality doesn't fit and you haven't fixed the dimensions, we reduce the resolution a step at a time, so you get a sharper small image rather than a blocky large one.
Frequently asked questions
How do I resize a photo to 20 KB for an application form?
Drop your photo, keep the size at 20 KB, and if the form specifies dimensions enter them with “Crop to exact size”. Download the JPG and upload it.
Is my photo uploaded anywhere?
No. The image is resized inside your browser and never leaves your device — important for ID photos and signatures.
Does it remove location and camera data (EXIF)?
Yes. The output is a freshly encoded image, so GPS location, camera model and other EXIF metadata from your phone are not carried over.
Is this an official tool for any government or exam portal?
No. It's an independent free tool. Always follow the exact size, dimension and format rules published in your form's instructions.
