Compress an Image to 30KB Online (Free)
Some upload forms cap attachments at 30KB per image. Others just load faster with small assets. Either way, you can cut almost any JPG, PNG or WebP down to 30KB with our free browser-based compressor.

Open Compress Image to 30KB OnlineHow much can you save?
A 12-megapixel photo can weigh 4-6MB. At 30KB you deliver the same image for under 1% of that weight — enough for previews, card headers and email embeds where full resolution is never seen anyway.
Compress an image to 30KB in three steps
- Open the Compress Image tool.
- Upload your image.
- Slide quality down until the preview shows 30KB or less, then download.
Add a resize before compressing when the source is a large photo — halving the dimensions typically divides the byte size by four.
Private by design
The compression happens locally in your browser tab. Sensitive photos and client work never touch a server — just your machine and the download button.

Frequently Asked Questions
Which quality percentage gives ~30KB?
Over 85% for thumbnails down to ~55% for large photos. Watch the live size counter and stop when the preview still looks sharp.
Does 30KB affect printing?
Yes — a 30KB JPG is web-only. It is ideal for screens and email, useless for print. Print demands full resolution instead.
Can I compress a PNG to 30KB?
Flat PNG graphics get there easily. Photos as PNG rarely do — convert to JPG or WebP first, or accept a lower quality.
