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

A little help getting the right result

Check Your Upload Requirements

Requirements differ by form and year. This tool checks a maximum file size; it does not guarantee acceptance or set exact dimensions.

How to Prepare Your Image in 3 Steps

1

Select or Drop Image

Choose a supported static JPG, PNG or WebP file up to 15 MB and 24 megapixels. Animated images and PDF files are not supported.

2

In-Browser Compression

Your browser tries quality and dimension settings within its processing limits. Time depends on the file and your device; a matching result is not guaranteed.

3

Download Verified File

Download after checking the result against your destination’s file type, size and dimension requirements.

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.

Supported inputs are static JPG, PNG or WebP files up to 15 MB and 24 megapixels. Before compression, the working image is limited to 12 megapixels; larger sources are reduced proportionally even if a generous byte limit is selected. The search may reduce dimensions further. Some images cannot reach the selected maximum within the time, attempt and minimum-dimension limits. The tool does not pad a smaller result to an exact size or enforce a minimum file size.

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.

Frequently Asked Questions

Is 100 KB enough for a document scan?

It depends on the document and resolution. Zoom in to check the smallest text before using the file. A larger permitted target may retain more detail.

Does this tool compress multiple MB camera photos to 100 KB?

You can try static JPG, PNG or WebP files up to 15 MB and 24 megapixels. Processing time and output quality depend on your device and image. Some files cannot reach the target within the tool limits.
