Reduce a image to 20 KB online

This free tool shrinks a image to 20 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 image under 20 KB

  1. Click the box above or drag your image onto it.
  2. The target size is already set to 20 KB. Change it if your form asks for something different.
  3. Optionally type a width and height if your form needs exact pixel dimensions.
  4. Press Compress and check the size shown next to the result.
  5. Click Download to save the new JPG.

How big can a 20 KB photo be?

As a rough rule of thumb, a 20 KB JPEG of an ordinary portrait photo holds about 320×430 pixels before quality has to drop noticeably. Photos with a plain background can carry more pixels, while busy or grainy ones carry fewer. This is only a guide, so the tool checks the real file size every time.

Tips for a clean 20 KB image

  • Crop tightly around the face or subject first. Fewer pixels means less detail to squeeze into the file.
  • A plain, light background compresses far better than a busy one, so retake the photo against a wall if you can.
  • If the result looks blocky, type a smaller width and height (a few hundred pixels wide) instead of pushing quality lower.

20 KB में फोटो का साइज़ कैसे करें

फॉर्म में फोटो अपलोड करते समय अक्सर साइज़ की सीमा होती है। यह टूल आपकी इमेज को सीधे आपके ब्राउज़र में 20 KB के अंदर ले आता है। इमेज किसी सर्वर पर अपलोड नहीं होती।

  1. ऊपर बॉक्स में अपनी इमेज चुनें या खींचकर छोड़ें।
  2. Target size में 20 KB पहले से भरा होगा। चाहें तो बदल सकते हैं।
  3. Compress बटन दबाएँ और नतीजे का साइज़ देखें।
  4. 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 reduce an image to 20 KB?

Choose your image above. The target already says 20 KB, so just press Compress. The tool picks the highest JPEG quality that stays under 20 KB and only shrinks the picture itself if quality alone is not enough. Then download the new JPG.

Will my photo look bad at 20 KB?

At 20 KB some softness is normal, because a file this small can only hold so much detail. Crop tightly and use a plain background to keep faces clear.

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. If you fill in only one box, the other side follows the original proportions.

Why is my result smaller than 20 KB?

The tool aims for the highest quality that fits under the limit, so the result can land a little below 20 KB. If your original was already under 20 KB, it is simply re-saved as a JPG.

Is my photo uploaded anywhere?

No. Compression 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. iPhone HEIC photos depend on your browser, so convert them to JPG first if one will not open. The output is always a JPG.
