Why resize an image to 100 KB?
Most exam portals — UPSC, SSC, IBPS, SBI and NTA NEET among them — only take images that fall inside a fixed KB window, and 100 KB is one of the caps you will run into most often. Push a file above the portal's limit and the form throws it back on the spot, which means you have to shrink it down first before the application will go through.
Doing this the old-fashioned way — opening Paint, Photoshop or GIMP — calls for installed software and a whole sequence of manual steps. This browser tool handles the same task in one click, uploads nothing, asks for no account and costs nothing.
Tips for the best result
- Start from the highest-quality original you have on hand — the tool compresses smartly to reach the target while preserving detail.
- For an exam photo, pick a sharp, well-lit shot taken against a plain white or light backdrop.
- Trim in close to the subject (leaving a little margin) before you resize, so more of the pixels survive at the target size.
- If the result comes out soft, go back to a somewhat larger original and run it through again.
Good to know: every file is exported as JPEG — the format Indian exam and ID portals are built around — so it goes up without a hitch on the first try.

Frequently asked questions
Is the Resize Image to 100 KB tool free?
It is, fully. You never sign up, the result carries no watermark, and there is no ceiling on the number of files you can run through it.
Is my image kept private?
Yes, entirely. The processing is done right in your browser through HTML5 Canvas, which means the file is never uploaded to any server and never leaves your device.
Does it work on a phone?
It does. Just open this page in Chrome or Safari on any iPhone or Android phone, load your file and save the result — there is no app to download.
Which file formats can I use?
You can feed in JPG, JPEG, PNG, WEBP and, on browsers that allow it, HEIC/HEIF. Everything comes out as JPEG, which keeps it compatible with Indian exam and ID portals.
Do I need to install anything?
Nothing at all. It works straight from the browser — Chrome, Firefox, Edge or Safari — whether you are on a computer or a phone.
Will resizing to 100 KB lower the quality?
The tool holds quality as high as possible while hitting the 100 KB mark. Since 100 KB leaves a fair bit of room, the result normally stays sharp and clean.
Why do exam portals set a KB file-size limit?
Bodies such as SSC, UPSC, IBPS, NTA and RRB cap file sizes in KB so their databases stay lean and uploads still complete on weak connections. Exceed the cap and the upload form simply turns the file away.
