30KB limits turn up on many online application forms for photographs and signatures. It is enough for a clear passport-style photo once the picture is cropped and reduced to a sensible size in pixels.
Tip: Take the photo against a plain, light background in good light. Busy backgrounds and image noise from low light use up file size without adding anything useful.
How to compress an image to 30KB
- Select the photo or image you want to make smaller — JPG, PNG, WebP or a screenshot.
- Check the target size is 30KB, or change it if your form asks for a different limit.
- Press Compress to 30KB. The tool finds the best quality that fits, and reduces the width and height only if it has to.
- Check the new size and the preview, then download the JPG.
Frequently Asked Questions
How do I compress an image to 30KB?
Select your image, make sure the target is 30KB and press Compress to 30KB. The tool tries the highest quality that fits; if even a low quality is still too big, it reduces the width and height step by step until the file is under 30KB. Then download the JPG.
Will my photo still look good at 30KB?
A cropped photo of a face looks clear at 30KB. The tool keeps the highest quality that fits, and only reduces the dimensions if it has to.
Will the file be exactly 30KB?
It will be at or just under 30KB — as close to the limit as possible without going over, because that keeps the most quality. Sizes are counted in thousands of bytes, so the file also passes forms that count 1KB as 1,024 bytes.
Can I compress a PNG or a screenshot to 30KB?
Yes. JPG, PNG and WebP images all work, including screenshots. The result is saved as a JPG, which is far smaller for photos; any transparent areas become white.
Is my photo uploaded anywhere?
No. The image is compressed inside your browser on your own phone or computer, and never sent to a server.
