How it works

How to resize an image to 100KB

  1. 1

    Add your photo

    Tap the upload box or drag and drop a JPG, PNG or WebP photo. You can add several at once.

  2. 2

    Keep the target at 100 KB

    The “Target size” is already set to 100 KB and the format to JPG. Change it if your form asks for a different limit.

  3. 3

    Resize

    Press the Resize button. The tool lowers the quality step by step, and only shrinks the dimensions if needed, to stay under 100 KB.

  4. 4

    Download

    Check the new size shown under each image and download it, ready to upload.

Features

Compress photos to 100KB without losing clarity

Hit the 100 KB limit on the first try, keeping as much quality as possible.

Exact 100 KB target

Set a size limit and the tool searches for the highest quality that still stays under 100 KB.

Keeps your photo sharp

Quality is reduced first; the width and height are only lowered when quality alone is not enough.

Any target size

Need 10 KB, 30 KB or 200 KB instead? Just type a different number in “Target size (KB)”.

Your photos are processed on your own device. They never leave your phone or computer.

Resize as many images as you want. No account, no limits, no logo added to your photo.

Bulk resize

Add many images at once and download each one, all with the same settings.

Works on phone and computer

Use it in Chrome, Safari, Edge or Firefox on Android, iPhone, Windows or Mac — no app to install.

FAQ

Resize image to 100KB — FAQ

How do I reduce my photo size to 100KB?

Add your photo above, keep “Target size” at 100 KB and the format as JPG, then press the Resize button and download. The tool automatically finds the best quality under 100 KB.

Which uploads need an image under 100KB?

Scanned documents, ID proofs, certificates and profile photos on many job, college and government portals have a 100 KB limit.

Can I compress a scanned document to 100KB?

Yes. Add the scan as a JPG or PNG image and press the Resize button. Text stays readable because the tool keeps the best quality that fits.

Can I resize many images to 100KB at once?

Yes. Add all your images and they are each compressed to under 100 KB.

Why is my image still above 100KB?

Make sure the format is JPG or WebP. PNG is a lossless format, so the target size cannot be applied to it.

Are my photos uploaded to a server?

No. Everything happens in your browser, so your photos never leave your device.
