How to compress image to 20kb
To compress an image to 20kb, drop it in the box above: the target is already set, so the tool finds the best quality that fits and you just download the result. Many job portals, university admissions and exam boards ask for a signature or photo between 10 and 20 KB. This page has the target already set to 20 KB: the compressor searches for the highest quality that stays under the limit and shrinks the width only if it has to.
When you need a 20 KB image
- Signature images for job and exam applications (often 10–20 KB)
- Small profile photos for government and bank portals
- Thumbnails for websites with tight upload limits
About the Image Compressor
Large photos slow down websites, bounce off email size limits and get rejected by online application forms. This compressor re-encodes JPG, PNG and WebP images in your browser so you can pick the balance between file size and sharpness yourself, or simply type a target such as 100 KB and let it find the best quality that fits.
When to use it
- Shrinking a passport photo or CNIC scan to the 50–200 KB limit many government and university portals require
- Making product photos load faster on a shop or WordPress site
- Sending a batch of holiday pictures over WhatsApp or email without hitting attachment limits
- Preparing blog images so Google’s page-speed checks stop flagging them
Tips for the best results
- WebP usually gives the smallest file at the same visual quality; use it for websites, but keep JPG for forms that only accept .jpg
- If a target size can’t be reached, set a max width (1600 px is plenty for most screens) and try again
- PNG is lossless, so compressing it changes little — convert photos to JPG or WebP for big savings
How to use the Image Compressor
- Open the Image Compressor and drop your image (or tap to choose one).
- Adjust the options — the preview updates instantly.
- Press Download to save the result. Nothing is uploaded.
Image Compressor FAQ
What pixel size should a 20 KB photo be?
Around 300–400 pixels wide keeps a face or signature sharp at 20 KB. Larger photos are shrunk automatically, but resizing first with the Image Resizer gives you control over the exact dimensions.
Will my photo look blurry at 20 KB?
A small photo looks fine on screen at 20 KB. Blur appears when a large, detailed photo is squeezed into 20 KB, so crop to just the face or signature first.
Can I compress several images to 20 KB at once?
Yes. Drop several images and each is compressed to under 20 KB. You can download them one by one or all together as a ZIP.
Which format gives the smallest file?
WebP is usually the smallest at the same visual quality, followed by JPG. PNG is lossless, so it stays large for photos. Use JPG if a form only accepts .jpg files.
Will compressing reduce the quality of my photo?
A little, but at quality 70–85% most people cannot see the difference on a screen. Very low targets such as 20 KB will show some blur, so pair them with a smaller width.
Is the Image Compressor free?
Yes. The Image Compressor is completely free with no sign-up, no daily limit and no watermark.
Is it safe to use the Image Compressor with private files?
Yes. The Image Compressor runs entirely inside your web browser, so your files and text are never uploaded to any server.
