- Add your photo or signature in the box above. It stays on your device.
- Check that Largest file size is set to 15 KB.

When you need an image under 15 KB
Used for small signature and thumbprint fields on some forms. Always follow the limit and pixel size written on the form you are filling in.

Tips for a clear picture at 15 KB
- Write your signature in dark ink on white paper and photograph it in good light.
- Crop to the signature only.
- Try black and white if the colour version is too large.
- Check that the result is still readable before you upload.

Frequently asked questions
How do I make a photo 15 KB or smaller?
Add the photo to the Image Resizer, set the largest file size to 15 KB and download the result. The tool reduces quality first and the picture size only if it has to.
Will my picture look blurry at 15 KB?
A small file means some detail is lost. A plain background, good light and a tight crop keep the result sharp. If it looks soft, raise the limit slightly or crop the picture more closely.
Which format should I use?
JPG gives the smallest file for photographs and is accepted almost everywhere. Use PNG only if the form asks for it, because PNG files are usually larger.
How do I make a photo under 100 KB?
Type 100 in “Largest file size”. The tool lowers the quality in small steps until the file fits. If it still does not fit, it can also shrink the picture a little. Tick “Keep the exact size” if you want the pixels untouched.
How do I make a passport photo?
Choose “Passport 35 × 45 mm”. The photo is cropped to that shape. Use the focus buttons to keep the face in the middle. Always check your own country’s photo rules, since they differ.
Will the picture be stretched?
Not unless you choose “Stretch”. The default keeps the proportions. “Crop to fit” cuts off the edges instead, and “Add padding” fills the extra space with a colour.
Which format gives the smallest file?
WebP and JPG are smallest for photos. PNG is best for logos and screenshots, but its size can only be reduced by making the picture smaller.
Is my picture uploaded?
No. It stays in your browser. Location and camera details are also removed when the image is saved again.
What is DPI for?
It matters when you give a size in cm, mm or inches, for printing. 300 dpi is normal for photos. It is saved inside JPG files.
Is Resize image to 15 KB really free to use?
Yes. It is completely free, with no sign-up, no watermark and no daily limit.
Is my file safe?
Yes. This tool works entirely inside your browser, so your file is never uploaded to our servers. It is cleared from memory when you close or refresh the page.
Do I need to install any software?
No. EduJobs Toolkit works in any modern browser on your phone, tablet or computer. Nothing to download or install.
