Quick answer
How do I resize a photo to 10KB?
Upload the photo on PhotoResizerKB's 10KB page, keep the 5–10KB preset and press Resize. The tool compresses the JPEG and slightly reduces its pixel size if needed so the file ends up under 10KB. Crop to just the face or signature first for the clearest result.
About This Tool
10KB is one of the smallest limits you will meet — typically for signature scans and thumb impressions on government and exam portals. At this size the tool also shrinks the pixel dimensions slightly when quality alone is not enough.
Commonly needed for:
- Signature uploads on exam and job forms
- Thumb impression scans
- Small profile icons and thumbnails
How to Use
- Tap the upload box and choose your photo (JPG, PNG or WEBP).
- The 10KB preset is already selected — change Min/Max KB only if your form asks for a different range.
- Press Resize to Target KB. The tool tries different quality levels until the file fits under 10KB.
- Check the new size shown in the result box and download the JPEG.
Tips for a Photo That Gets Accepted
- Start from the original photo from your camera or gallery, not a WhatsApp-forwarded copy — it keeps more detail after compression.
- If the form also gives pixel dimensions, crop the photo first with the Image Cropper, then come back here.
- Output is always JPEG, which most upload forms accept. If a form insists on PNG, use the Image Format Converter after resizing.
Frequently Asked Questions
How do I reduce a photo to 10KB?
Upload the photo above, keep the 10KB preset and press Resize. The tool adjusts JPEG quality (and size, if needed) until the file is between 5KB and 10KB, then gives you a download button.
Will my photo be uploaded to a server?
No. The compression runs inside your browser using the Canvas API, so the photo never leaves your phone or computer.
Why does my 10KB photo look blurry?
10KB holds very little data, so a full-size photo has to be compressed heavily. Crop away the background first so the important part (face or signature) uses the available bytes.
Can I make a signature exactly 10KB?
Yes. Scan or photograph the signature on plain white paper, crop it tightly and resize it here. Signatures compress very well, so 10KB is usually easy to reach with good clarity.
