Compress WebP to 10 KB
WebP packs more quality into tiny files than JPEG. This page saves every image as WebP under 10 KB — ideal for thumbnails, icons and placeholders. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 10 KB?
Many sites cap images at 10 KB — typically for signatures, thumbnails and the small photo fields on online application forms. That leaves room for roughly a 290×220 WebP photo.
About 290×220 px fits
At medium quality a detailed WebP photo of roughly 290×220 pixels lands under 10 KB; at high quality about 200×150.
WebP stretches the limit
WebP packs about 30% more detail into 10 KB than JPG, but check that the site you upload to accepts .webp files.
358× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 358×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 10 KB, quality is basic. Best for small ID photos and signatures.
Scans and documents
A scanned A4 page of about 350×500 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
10 KB is measured as 10,240 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.
10 KB at a glance
| Limit in bytes | 10,240 bytes |
|---|---|
| Photo at high quality | about 200×150 px |
| Photo at medium quality | about 290×220 px |
| Photo at low quality | about 400×300 px |
| Scanned A4 document | about 350×500 px |
| Reduction from a 12 MP phone photo | about 358× |
| Output format | WebP |
| Typical use | Signatures, thumbnails and the small photo fields on online application forms |
Compress an image to 10 KB in 3 steps
- Add your image — JPG, PNG, WebP or a phone photo.
- The target is already set to 10 KB. Leave “Remove EXIF metadata” ticked to save extra bytes.
- Click Compress and download a WebP under 10 KB.

Tiny WebP images for fast pages
At 10 KB, WebP typically looks noticeably cleaner than JPEG — fewer blocky artefacts, smoother gradients. That makes it the best format for small thumbnails and low-quality placeholders that load before the real image.
Pixel guide: about 250–300 pixels wide.
Transparency is kept. Unlike JPEG, WebP stores transparent areas, so small icons stay see-through.
Browser support. All current browsers show WebP. Some upload forms still accept only JPG — for those use JPEG to 10 KB.
Nearby WebP target: 20 KB.

Frequently asked questions
Is WebP better than JPEG at 10 KB?
Usually yes — at the same file size WebP shows fewer artefacts. Use JPEG only where a site requires it.
How many pixels fit in 10 KB?
For a detailed WebP photo, about 290×220 at medium quality or 400×300 at low quality. Simple graphics and scans can be much larger.
What quality will a 10 KB photo have?
Basic. Best for small ID photos and signatures. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 10 KB the same as 10,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 10 KB is 10,240 bytes. The tool uses the same count, so a file it marks as under 10 KB is accepted.
Should I use JPG or WebP for 10 KB?
JPG is accepted everywhere and is the safe choice for forms. WebP holds about 30% more detail at the same size, ideal for websites that support it.
Why is my file still over 10 KB?
Very large or detailed images may not reach 10 KB by quality alone. Resize it first (for example to 290 pixels wide) with the resizer, then compress again.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and it will still work.
