Compress Image to 30KB

Compress an image toward 30KB for strict form, document, and website upload limits.

TargetAbout 30KB
Works onDesktop and mobile browsers
Choose an image to target roughly 30 KB and reveal optimization settings.

About this tool

Adjusts image quality and dimensions locally to produce the closest usable result at or below 30KB.

Common use cases

  • Push an image toward a 30KB limit for forms or upload gates.
  • Shrink images faster than manually testing export settings.

How to use it

  1. Upload a JPG, PNG, or WebP image.
  2. Run the automatic compression toward 30KB.
  3. Review the dimensions and final file size, then download the result.

Best for

  • Upload systems that reject files over about 30KB
  • Forms, portals, and document sites where the size cap matters more than the canvas size
  • Users who want the browser to optimize automatically before they fine-tune anything manually

Input and output notes

  • Accepted inputs: .jpg, .jpeg, .png, .webp.
  • Target-size compression is best effort and may stop at the closest acceptable result.

Resize, reduce, or compress an image to 30KB

People describe the same file-size task in several ways: resize an image to 30KB, reduce a photo to 30KB, compress a picture under 30KB, or make an image 30KB. This page keeps those requests on one canonical tool because the browser uses the same target-aware optimization for each one.

How the 30KB target is reached

  • The optimizer first searches for the highest usable JPG or WebP quality that fits the target.
  • If quality adjustment is not enough, it reduces dimensions gradually while preserving the aspect ratio.
  • PNG can remain larger because it is lossless; JPG or WebP is usually more suitable for strict KB limits.

When a 30KB target makes sense

This page is best for upload limits, form gates, and document systems that reject oversized images.

  • Use this page when the upload cap is close to 30KB and you want the browser to optimize automatically.
  • Start with JPG or WebP when the target is strict and visible quality matters.
  • Switch to the manual image resizer if you need exact pixel dimensions before compressing.

Limits to know

  • Very large images still depend on available browser memory.
  • Lossy formats such as JPG and WebP can trade quality for smaller files.

Privacy

This tool runs in the browser, so pasted content and uploaded files stay on the current device during normal use.

Common next steps

Compress Image to 15KB

Jump to a different size limit when the form or portal uses a different upload cap.

Compress Image to 30KB

Jump to a different size limit when the form or portal uses a different upload cap.

Choose the right image-size workflow

Use Compress Image to 30KB when the upload cap is fixed

This page is best when the requirement is stated as a file size target rather than a pixel dimension.

Use Image Resizer for exact width and height control

The manual resizer is a better fit when you know the destination dimensions and want to tune format and quality yourself.

Use Bulk Image Resizer for many files at once

Jump to batch processing when the job is about handling a folder of product photos, screenshots, or listings.

Common questions

Are my images uploaded to a server?

No. Images are decoded, resized, and exported locally with browser APIs and canvas, so the file stays on your device during normal use.

Will this hit exactly 30KB?

Not always. The optimizer works toward the target locally and stops at the closest acceptable result when a perfect match would damage quality too aggressively.

Which formats work best for strict KB targets?

JPG and WebP usually reach tight file-size targets more easily than PNG. PNG stays useful when you need lossless output or transparency.
