What It Takes to Reach 20KB

Output format, visual complexity, quality and pixel dimensions all affect this restrictive target.

SOURCE2.4 MB
QUALITYQ 42
RESULT19.8 KB
DETAIL

Detailed Photographs

Noise and fine texture can require stronger quality reduction.

PIXELS

Large Sources

High pixel counts may require resize fallback to reach 20KB.

FORMAT

Output Format

JPEG, WebP and AVIF can each be tested for target-size output.

The 20KB Compression Route

  1. 1

    Open the Image

    Add a browser-readable image and enter the editor with the 20KB maximum ready.

  2. 2

    Search Quality First

    Vicoco tests JPEG output quality before changing pixel dimensions.

  3. 3

    Review Resize Fallback

    If dimensions were reduced, compare the smaller result before download.

Choose a Format for a Very Small File

Compare the actual source in JPEG, WebP or AVIF instead of assuming one format always gives the best result.

Read the 20KB Result

A very small target can require lower quality, smaller dimensions or both.

Actual Bytes

Use the generated file-size value rather than estimating from quality.

Visual Detail

Inspect edges, texture and text at the generated quality.

Pixel Dimensions

Confirm the output is still large enough for its intended use.

FAQs

How do I compress an image to 20KB?

Add the image, keep the 20KB target, let Vicoco search output settings, and download after checking quality and dimensions.

Is 20KB an exact size or a maximum?

It is a maximum. A successful result can be smaller than 20KB.

Why does a 20KB image look less detailed?

Reaching a very small limit can require lower quality, smaller pixel dimensions, or both, especially for detailed photographs.

Can Vicoco resize the image automatically?

Yes. You can enable resize fallback so the editor can reduce dimensions if quality alone cannot meet 20KB.

Can PNG use the automatic 20KB target?

The automatic target control supports JPEG, WebP and AVIF output. A PNG source can be converted to one of those formats.

Can every image reach 20KB?

No result is guaranteed for every source and setting. Vicoco reports when the target was not met.

Are images uploaded to a server?

No. Compression runs locally in the browser.
