Compress Signature to 15 KB

Reduce a signature to 15 KB online

This free tool shrinks a signature to 15 KB or less right in your browser. It tries different JPEG quality levels and keeps the highest one that still fits under the limit. If quality alone cannot get there, it scales the picture down a little at a time until the file fits.

Application forms, job portals, scholarship sites and government services often set a maximum upload size. Check the instructions on your form for the exact size, format and dimensions it asks for.

How to get a signature under 15 KB

Click the box above or drag your signature onto it.
The target size is already set to 15 KB. Change it if your form asks for something different.
Optionally type a width and height if your form needs exact pixel dimensions.
Press Compress and check the size shown next to the result.
Click Download to save the new JPG.

Tips for a clean 15 KB signature

Sign with a dark pen on plain white paper and take the photo in even light, without shadows across the page.
Crop tight around the signature so empty paper does not waste pixels.
A signature is mostly white background, so it compresses very well. A wide, short crop is completely normal.
At 15 KB keep the picture small. A few hundred pixels wide is often enough for a signature.

15 KB में हस्ताक्षर (signature) का साइज़ कैसे करें

फॉर्म में हस्ताक्षर (signature) अपलोड करते समय अक्सर साइज़ की सीमा होती है। यह टूल आपकी इमेज को सीधे आपके ब्राउज़र में 15 KB के अंदर ले आता है। इमेज किसी सर्वर पर अपलोड नहीं होती।

ऊपर बॉक्स में अपनी इमेज चुनें या खींचकर छोड़ें।
Target size में 15 KB पहले से भरा होगा। चाहें तो बदल सकते हैं।
Compress बटन दबाएँ और नतीजे का साइज़ देखें।
Download दबाकर नई इमेज सेव कर लें।

अपलोड करने से पहले फॉर्म में लिखा साइज़ और फॉर्मैट ज़रूर जाँच लें।

Frequently asked questions

How do I compress a signature to 15 KB?

Choose your signature image above and press Compress. The tool finds the highest JPEG quality that stays under 15 KB and downloads the result as a JPG.

Will my signature stay readable at 15 KB?

In most cases yes. A dark signature on a white background compresses very well. Avoid cropping so tightly that strokes touch the edge of the picture.

Should I scan my signature or photograph it?

Either works. Scan at a moderate resolution or photograph it in even light on plain white paper, then compress it here.

Can I also set an exact width and height?

Yes. Type a width and a height in the optional boxes and the picture is cropped to fill that size without stretching.

Is my signature uploaded anywhere?

No. Everything runs in your browser, and the file never leaves your device.

Which file types can I use?

PNG, JPG, WEBP and GIF images open in every modern browser. The output is always a JPG.
