Resize image to 100 KB

What fits in 100 KB

A 100 KB limit is typical for photos and scanned documents on portals with looser limits, profile pictures and email attachments that must stay small.

Myriadfile first draws your image at the size you ask for, then searches for the highest JPG quality whose file is still under 100 KB. If you leave width and height empty it may shrink the image too, but if you set exact pixels it keeps them and only adjusts quality. At 100 KB a photo can be 600–1000 px wide and still look sharp. For documents, use the PDF tools so multiple pages fit in one file.

How to resize an image to 100 KB

1. Choose the image. A photo from your phone, a scan, or a HEIC file from an iPhone.
2. Enter the form’s rules. Max size is set to 100 KB. Add a minimum size and exact width and height if the form specifies them.
3. Pick crop or fit. “Crop to exact size” fills the frame and trims edges; “Fit inside” adds white borders instead of cutting.
4. Download and upload. The result shows the exact size in KB and bytes. Download it and upload to the form.

Settings explained

Min size (KB)

Some forms reject files that are too small. If the image is below the minimum at full quality, blank comment data is added inside the JPEG to reach it; the picture itself does not change.

Width and height

Exact output pixels. Fill one to keep proportions, or both to crop or pad to that shape.

Black and white

Converts to grayscale. Ideal for signatures and saves space.

Format

JPG is what almost every form wants. PNG cannot be compressed by quality, so only use it if required.

Photos for specific exams

If you are applying for a particular exam, use its page, where the preset matches the official notice: SBI photo and signature, SSC signature, NEET (UG). Always check the current notice too, because requirements change between years.

Troubleshooting

“Cannot get under 100 KB”

The pixel size is too large for the limit. Reduce width and height, or clear them so the tool can shrink the image automatically.

The portal says the file is too small

Enter the portal’s minimum in Min size; the file is raised to it.

The face is cut off

Switch Fit to “Fit inside, white border”, or crop your photo first so the face is centred.
