Increase Image Size to 30KB
Enter 30 and get a JPG that is exactly 30KB, not a byte less.
Advanced (optional): exact pixels or minimum KB
Many forms ask for pixels as well as KB. Leave empty if yours does not. Examples are common sizes only – always use the size your form states.
✅ Done! Your images are ready
About the 30KB image
Photo fields that demand a minimum of 30KB often reject tiny phone crops or heavily compressed pictures. This page raises the file to precisely 30KB while keeping the picture untouched.
How to increase an image to exactly 30KB
- Select your image. A JPG keeps its original pixels; other formats are converted to JPG first.
- Check the size. The box is already set to 30 and Increase is selected. Change the number if needed.
- Press the green button and download a file that is exactly 30 KB.
Increase mode keeps your picture and adds invisible padding so the file size matches exactly.
Where you need a 30KB image
Passport-style photo minimums
Some photo fields state a range, such as 30KB to 60KB.
Cropped selfies
A tight crop can fall below the minimum even though it looks fine.
Re-saved screenshots
Small screenshots converted to JPG can end up very light.
Scanned seals
Simple black-and-white scans produce very small files.
What to expect at 30KB
You get the same picture in a file that measures exactly 30KB. Use a sharper, larger original if you need better visual quality.
30KB image FAQ
What if my photo is already bigger than 30KB?
The tool then compresses it down and pads the last few bytes, so the output is still exactly 30KB.
Is the size exactly 30.0 KB in Windows?
Yes. The file is 30 x 1024 bytes, which Windows, Android and iPhone all show as 30 KB.
Does the padding add anything visible?
No. Padding is stored in zero-filled comment data that is not drawn.
Is my photo uploaded when I increase it to 30 KB?
No. Everything happens inside your browser, so your picture never leaves your device. No signup, no watermark.
