Why does my 99 KB file fail a 100 KB limit?

Servers often measure in kibibytes, so 100 KB on the server is a slightly different number than on your device. Leaving a 10% margin avoids the problem.

Does 90 KB look worse than 100 KB?

No, the difference is not visible. The extra margin costs you nothing you can actually see.

Is my image uploaded to a server?

No. ShantiTools compresses the image entirely inside your browser — the file never leaves your device.

90 KB is the safe version of a 100 KB limit. When a portal keeps rejecting a file that measures 99 KB on your computer, the mismatch is in how the server counts kilobytes, and dropping to 90 KB ends the argument.

How it works

Upload any JPG or PNG from your phone or computer.
We fit it to 560×740 px and tune JPEG quality until the file stays under 90 KB. Prefer your photo's own shape? Tick Keep original dimensions before choosing a file — nothing is cropped.
Download and upload it straight to the form.

Everything runs on your device — your image is never sent to a server.

Tips for a clean 90 KB file

•If an upload fails silently with no error, the file size is the first thing to rule out. Try 90 KB before you change anything else.
•Clear the file input and re-select the new file. Some portals keep the old file in memory after a failed attempt.

Common mistakes

•Uploading a screenshot — screenshots are already compressed and often produce blocky JPEGs. Use the original photo instead.
•Ignoring dimensions — a file can be the right KB but the wrong shape. This page sets 560×740 px automatically.
•Cropping too tightly — leave a small margin around the head and shoulders so the form does not cut the face.
•Wrong background — busy backgrounds eat KB and can get rejected. Plain white or light works best.

Troubleshooting

The result is still too big: Start with a smaller source file or crop closer to the face. If the form allows a smaller size, try 80 KB.
The result is too small: The source image may be very low resolution. Upload a larger original photo and retry.
My form rejected the upload: Double-check both the KB limit and the pixel dimensions in the form. Some forms also require exact aspect ratios (e.g. 3.5×4.5 cm).
