Increase Image Size to 100 KB
When a form says the image must be at least 100 KB and your file is 35 KB, you do not need a new photo. This page grows the same image to 100 KB, keeping its width and height, so it clears the upload check.

Auto raises the quality first and then adds invisible padding, so the picture looks the same. Upscale makes the image larger in pixels, which also changes its dimensions.
Upper limit for upscaling: 200% doubles width and height. The tool stops as soon as the minimum size is reached.
Same as input keeps a JPG a JPG and a PDF a PDF. PNG files are naturally larger than JPG for the same picture.
Metadata only, 0 keeps the original value. Some exam portals check for 200 or 300 DPI.
How to use this tool
- 1
Choose the image
Upload the JPG, PNG, WebP, HEIC or BMP the form refused. Several applicants' photos can go in one batch of up to 20 files.
- 2
Confirm 100 KB
Minimum size is already 100 and the unit is KB. If the notice gives a range such as 100–200 KB, keep 100 or type 110 for a little headroom.
- 3
Increase and upload
Press Increase size, download the file and upload it to the form. Check the size shown by the portal itself, since some count a kilobyte as 1,024 bytes.
How do I make a photo at least 100 KB?
Upload it, keep Minimum size at 100 KB and press Increase size. The image is re-saved at higher quality and, if needed, padded with invisible data until it reaches 100 KB, with the same pixel dimensions.
Increase image size to 100 KB: what changes inside the file
A file's size in KB depends on how much the encoder could squeeze it, not on how good it looks. A passport-style photo against a plain wall compresses very well, and phones save JPGs at moderate quality to spare storage. The result is a perfectly clear 30–40 KB file that a portal with a 100 KB floor turns away.
Recent NTA information bulletins for JEE Main and NEET (UG) have listed photographs between 10 KB and 200 KB, and some state recruitment and university admission portals ask for scans of 100 KB or more. Rules change from one notice to the next, so read the current one before you apply; the method below works for any number you enter.
Getting from 35 KB to 100 KB takes roughly 65 KB of new data. The tool adds it in the gentlest order: first more JPG quality, which keeps a little more of the original detail, then padding bytes stored in a part of the file that image viewers skip. Nothing visible is invented, and nothing is hidden from the portal either: the file is a standard image that simply weighs more.

Three ways to add 60–70 KB
Raise quality
Re-save the JPG at a higher quality setting.
- Keeps a little more detail
- Pixels and dimensions unchanged
- May fall short of 100 KB on small photos
Add invisible padding
Write filler into a metadata segment that viewers ignore.
- Reaches any target
- Picture is byte-for-byte unchanged
- Adds no visual quality
Upscale pixels
Enlarge width and height until the file is big enough.
- Changes the dimensions
- Limited by Max enlargement
- Softens edges slightly
Most people should not touch these settings. Pick a single method under Advanced settings only when you know why: Raise quality only if you dislike the idea of padding, Upscale pixels if the form asks for a bigger image in both KB and pixels. Keep Keep metadata on, because stripping camera data takes bytes away again.
If your form's minimum is lower, start from increase image size to 50 KB instead, or browse every method on the increase image size page.
Increase image size to 100 KB questions
How do I increase image size to 100 KB without changing the dimensions?
Leave How to add size on Auto and Keep dimensions on, which is how this page opens. Auto first re-saves the JPG at a higher quality and then adds invisible padding until the file reaches 100 KB. The pixel width and height never change.
Why is my result 101 KB and not exactly 100 KB?
The tool aims at or just above the number so the file never falls short, because a minimum is a floor. A kilobyte or two over 100 is normal. If a form also has a ceiling, such as 200 KB, you still have plenty of room.
My photo is only 15 KB. Can it really reach 100 KB?
Yes. Quality alone may only double the size, so padding makes up the rest, and padding has no practical limit. The picture will look exactly like the 15 KB version, though; if the photo is blurry or tiny, a fresh photo is the better fix.
Does a photo look sharper at 100 KB than at 30 KB?
Only slightly, and only for the part that came from raising JPG quality. Padding bytes are never displayed, and upscaling stretches existing pixels rather than adding detail. The extra kilobytes satisfy the checker, not the viewer.
The form asks for 100 KB and exactly 200 × 230 pixels. Which method should I use?
Auto with Keep dimensions on. Upscale pixels would push the image past 200 × 230 and the form would reject it for the wrong dimensions instead. Resize to the exact pixel size first, then increase the file size here.
What if the image must stay under 100 KB instead?
That is a maximum, the opposite problem. Use compress image to 100 KB, which lowers quality step by step until the file fits below the limit.
