Compress Signature to 10KB
Your exam portal says "signature must be under 10KB" but your file is 80KB? This compressor reduces the file size to exactly under 10KB without destroying the signature strokes. It works differently from generic photo compressors because it treats thin ink lines as the priority, not smooth gradients.

How it works
Upload your signature scan
Drop any JPG, PNG, or HEIC signature image. Phone photos work fine.
Set 10KB target
The compressor is already configured for 10KB. Adjust only if your portal specifies a different limit.
Download the compressed file
The output preserves signature legibility while meeting the exact KB ceiling.
Frequently asked questions
What is the difference between resize and compress?
Resize changes the pixel dimensions (e.g., 140x60). Compress reduces the file size (e.g., 10KB) by adjusting image quality. For most exam portals, you need both - resize to the correct dimensions AND compress under the KB limit.
My 10KB signature looks blurry. How do I fix it?
Start with a cleaner scan. The sharper the original, the better the compressed output. Use the signature cleaner to remove background noise before compressing - this gives the compressor more room to preserve stroke detail.
Is 10KB the same as 10 kilobytes?
Yes. 10KB = 10,240 bytes. Portal validators check the file size in kilobytes, not dimensions. Your signature file must be strictly below this ceiling.
