How do I compress an image to 8 KB?

Upload your photo above. We resize it to 220×300 px and compress the JPEG until it lands under 8 KB, all inside your browser.

Why choose 8 KB when my form says 10 KB?

Some portals measure 1 KB as 1,024 bytes and others as 1,000, and phones round sizes differently. An 8 KB file clears a 10 KB cap no matter how it is measured.

What pixel size is best for an 8 KB photo?

Around 220×300 px. Bigger dimensions force heavy compression and blur the face; this size keeps the photo recognisable at 8 KB.

Will my signature stay readable at 8 KB?

Yes, if it is signed in dark ink on white paper and cropped closely. Clean contrast compresses well, so the strokes stay sharp.

Is it safe to compress my photo here?

Yes. Compression runs entirely in your browser — your photo is never uploaded to any server.

My 8 KB photo looks blurry. What can I do?

Use a clearer original with good lighting and a plain background, and avoid re-saving screenshots. If the form allows more, try the 10 KB or 20 KB tool.

Is my image uploaded to a server?

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

Compress Image to 8 KB — 8 KB Photo Size Resizer Online

8 KB is the go-to size when a form caps uploads at 10 KB or less. Portals often count 1 KB as 1,024 bytes while phones show 1,000, so a file that looks like 9.9 KB can still be rejected. Landing at 8 KB leaves safe headroom — and at 220×300 px the face stays clear.

Tips for a clean 8 KB file

•Start from the original camera photo, not a screenshot or WhatsApp copy — re-compressed files turn blocky at 8 KB.
•For a signature, sign in dark ink on plain white paper and crop tightly around it before uploading.
•Use a plain, light background. Busy backgrounds eat file size that the face needs.
•If your form states exact pixel dimensions, use the matching dimension tool instead — this tool resizes to 220×300 px.

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 220×300 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 5 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).
