How to compress an image to 10 KB
- Drop your JPG, PNG, WebP or HEIC image into the box above, or click to choose it.

- Wait a second while the image is optimised, then click Download.
Why 10 KB?
Many websites cap uploads at 10 KB, especially for tiny thumbnails, signature images and strict upload limits. A typical phone photo is 2–5 MB, so it gets rejected. This tool keeps the best possible quality while guaranteeing the file fits the limit.
Frequently asked questions
How do I reduce a photo to 10 KB?
Drop your image into the tool above. It automatically finds the highest quality that fits under 10 KB, and only shrinks the dimensions if quality alone is not enough. Then click Download.
Are my images uploaded to a server?
No. FileCrafty compresses images entirely inside your browser using your own device. Your files are never sent anywhere, which also makes it fast.
Will the image still look good at 10 KB?
For small targets like 10 KB the tool lowers quality first and then dimensions. Faces and documents stay readable; for the best result start from a well-lit, cropped photo.
Can I compress iPhone HEIC photos?
Yes. HEIC photos are converted and compressed in one step, so you get a JPG or WebP that any website accepts.
Should I choose JPG or WebP?
Choose JPG if a form or website asks for it — it works everywhere. WebP gives smaller files at the same quality and keeps transparency, but some older forms do not accept it.
