Auto keeps JPEG inputs as JPEG and uses WebP for other inputs when supported. JPEG fallback uses a white background.

THREE SIMPLE STEPS

How to Compress Photos to 20 KB in 3 Steps

Select or Paste Image

Drag, browse, or paste any JPEG, PNG, or WebP photo up to 15 MB. The binary header is instantly validated in your browser.

Choose a size, let us compress

The engine searches the optimal balance of quality and dimensions to fit within 20,000 bytes. Review the preview because compression can reduce detail.

Verified Safe Download

Inspect before-and-after image quality on the split slider. Download the file once its size and image header have been checked.

BUILT FOR A CLEAR RESULT

Small files. Clear limits.

Verified ≤ 20,000 Byte Limit

We define 20 KB as 20,000 decimal bytes. A download link is generated only after testing the real encoded blob size.

Zero Server Uploads

All pixel decoding and compression takes place in your browser's memory sandbox. Zero image data is sent to our servers.

Your image stays local

Image processing runs locally. The website uses Google Analytics for usage measurement; see our privacy policy for details.

A GOOD FIT, NOT JUST A SMALL FILE

Make every kilobyte count.

How compression works

Choose the right output format

Use JPG when your form asks for a photograph in JPEG format. JPEG replaces transparent areas with white. Use WebP when the destination accepts it and you need a smaller file or transparency.

PNG is supported as an input. Downloads are JPEG or WebP; this tool does not export PNG or PDF.

Small enough, and still readable

Compression can soften details and reduce pixel dimensions. Check faces, letters and signature strokes in the comparison before downloading. File size in KB and image dimensions in pixels are different requirements.

For a strict 20 KB maximum, this site checks against 20,000 bytes. See why that differs from 20 KiB.

Still getting an upload error?

Check the destination’s required file type. A small WebP file will not work in a JPG-only field.
Check both minimum and maximum file size. A result under 20 KB may also be below a required 10 KB minimum; this tool enforces a maximum only.
Check the required pixel dimensions, crop, background and photograph date. This compressor does not set an exact width, height or DPI.
If the result is blurry, crop away unnecessary background in an image editor first, then try again. Choose a larger target only if the destination allows it.

Knowledge Base

Frequently Asked Questions

Answers about file limits, privacy, formats and output quality.

Why does "20 KB" mean 20,000 bytes instead of 20,480 bytes?▼

Standard SI decimal units define 1 KB as 1,000 bytes, so this site treats 20 KB as 20,000 bytes. Some software uses binary units or rounds its display. The 20,000-byte ceiling meets forms that specify that maximum, but format, dimensions and minimum-size requirements can still apply.

Are my images uploaded to any remote server or stored anywhere?▼

No. The selected image is validated, decoded and compressed in your browser. The website uses analytics for page usage, but the image file and its pixels are not uploaded by the compressor. See the privacy policy for the full boundary.

Why did my image dimensions or resolution decrease?▼

The compressor first tests quality settings at the original dimensions. If the file does not fit, it reduces dimensions proportionally and checks the encoded byte count. Inspect the preview because a small result can lose fine detail or legibility.

What image formats are supported?▼

You can compress static JPEG, PNG, and WebP images up to 15 MB in file size and 24 Megapixels. Animated formats (GIF, animated WebP, APNG) are rejected because single-target static compression is designed for static document and photo uploads.

Can I set a different target size like 50 KB, 100 KB, or 200 KB?▼

Yes. While 20 KB (20,000 bytes) is the default preset, you can use any dedicated preset page — 10 KB, 30 KB, 50 KB, 100 KB, 200 KB, 500 KB — or type any custom target between 5 KB and 5,000 KB with the image size reducer in KB.
