How to reduce an image to 100 KB
- The Under 100 KB preset is selected. Enter a minimum in Min KB only if your form asks for one.
- If the form asks for exact pixels, enter the width and height. Otherwise leave them empty and the tool picks a sharp size that fits.
- Choose your image, tap Resize & Compress, check that every item shows ✅, then download.
A 100 KB limit is common for photos of documents (certificates, ID cards, mark sheets) and for larger profile photos on job and admission portals. With 100 KB, the tool can usually keep a lot of detail, so text in a document photo stays readable.
Always check the size rules in the official notification for your form.
Frequently asked questions
Can I compress a photo of a document to 100 KB?
Yes. A photo of a certificate or ID card can be reduced to under 100 KB as a JPG. Leave the dimensions empty so the tool keeps the text readable. PDF files aren't supported yet.
Why is my file much smaller than 100 KB?
If the image is already small or the dimensions you set are small, it may fit well below 100 KB at full quality. That's fine unless your form also has a minimum size.
Is my image uploaded?
No. Processing happens in your browser and the file never leaves your device.
