The quick way
Open the compress image to 30KB tool, choose your picture and download the result. It finds the best quality that stays under 30KB and only shrinks dimensions if it has to.
Why 30KB is hard
A modern phone photo is 2 to 5MB, so reaching 30KB means cutting the file to around 1 percent. That works best with simple pictures like signatures, ID photos and scans on a plain background.
Tips for a better result
Crop away empty space first, use a plain background, and start from a JPG. Busy photos lose more detail at this size.
If it is still too big
Reduce the pixel size first with the resize tool, then compress. You can also try 50KB if the form allows it.
Private by design
Your picture is processed inside your browser and is not uploaded. See the full guide to reducing image size in KB.
Why 30KB is hard (and how to make it easy)
30KB is very small. A typical phone photo is 2 to 6MB, so it has to shrink by 70 to 200 times. Two things make that possible: reducing the number of pixels (for example 200×230 instead of 3000×4000) and lowering the JPG quality. The tool does both for you in the right order and stops at the best quality that fits.
Step by step
- Crop the photo so the face or signature fills the picture. A tighter crop needs less compression.
- Open the compress to 30KB tool and choose the cropped photo.
- Keep the target at 30 KB and wait a second.
- Check the preview and the size shown under it, then download.
What to expect for different pictures
| Picture | Difficulty | Result |
|---|---|---|
| Signature on white paper | Very easy | Dark ink stays readable |
| Passport-style photo | Easy if cropped | Face stays clear at around 200 × 230 px |
| Photo of a document | Harder | Small text can blur; use 50KB if allowed |
| Busy photo with lots of detail | Hardest | Expect some softness |
Tips for the best result
- Use a photo taken in daylight; noisy dark photos compress badly.
- Do not screenshot a photo, because the screenshot is already compressed.
- If the form states exact pixels, resize first, then compress.
- Keep the original; you may need another size later.
If it is still not under 30KB
Crop tighter, or start from the original instead of an already compressed copy. If the result looks too soft and the form allows it, try 45KB or 50KB. Do not go far below the limit; aim for 28 to 30 KB.

Questions
How do I compress an image to 30KB?
Crop the picture, open the compress to 30KB tool, choose the image and download the result. The tool lowers quality and, if needed, size until the file is under 30KB.
Will my photo lose quality at 30KB?
Yes, some. The tool keeps the best quality that fits, and a tight crop of a face or signature looks fine.
Is the image uploaded anywhere?
No. Compression runs in your browser.
Why is my image bigger than 30KB after compressing?
Very large originals may need more reduction. Crop first and run the tool again from the original photo.
