Resize Image to 100 KB Online

Bring a photo, scanned page or screenshot down to 100 KB or less while keeping text and faces readable. Pick the pixel size, set the KB range and download a JPG.

What does the form ask for?

Or paste the rules from your notification

For example: “Signature: 140 x 60 pixels, file size 10 KB to 20 KB, JPG”. Paste one document at a time.

You will get a 600 × 750 pixel JPG of at most 100 KB. The form has no fixed pixel size, so we use a good default. You can change it.We aim for 0 to 100,000 bytes. This passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

Add your photograph

Your image stays on this device. It is never uploaded.

Already have a file? Check it before you upload

See if your file follows the rules above before you upload it. Most forms don’t tell you what is wrong.

How to resize an image to 100 KB

  • Add the image. Photos, scans and screenshots all work.
  • The limit is already 100 KB. Change it to 150, 200 or 500 if your form allows more.
  • Set the width and height. For a document or declaration, a wider size such as 800 × 400 or 1000 × 1400 pixels keeps writing readable.
  • Download the JPG and check the size shown below the preview.

When forms ask for 100 KB

A 100 KB limit is common for larger photos (such as 600 × 600 pixels and above), for handwritten declarations and for scanned documents like certificates or ID cards on admission and job portals. For example, IBPS asks for the handwritten declaration at 800 × 400 pixels between 50 KB and 100 KB.

Tips for scanned documents and handwriting

  • Photograph the page flat, in daylight, with the phone held straight above it.
  • Choose “Signature” or “Declaration / document” as the Document type and keep “Clean up the paper” on. Grey or yellow paper becomes white and ink becomes darker, which also makes the file smaller.
  • Crop away the table or floor around the page so the pixels go to the writing.
  • If text looks soft at 100 KB, increase the pixel size a little rather than raising quality: more pixels help readability more than extra KB.

Questions

Can I reduce a PDF to 100 KB here?

No. This tool works with images (JPG, PNG, WebP) and always saves a JPG. If your form wants a PDF, take a photo of the page, make it 100 KB here and then convert the JPG to PDF with your phone’s print or share option.

How do I resize an image to 100 KB without losing quality?

Set a pixel size close to what the form needs instead of keeping the full camera size. At form sizes, 100 KB allows very high JPG quality, so you will not see a difference.
