Processing happens in this browser tab, so files are not uploaded to Metyris for processing. Reloading or closing the page clears working data, though your browser may retain temporary files or downloads. Very large files can exceed available browser memory.

How to use Compress Image to 100KB
- Select your image.
- The target is preset to 100 KB. Choose WebP or JPG; dimensions stay unchanged.
- Compress and check whether the measured result meets the target before downloading.
What if my image cannot fit below 100 KB?
The tool reports the actual result and whether it is strictly below 100 × 1,024 bytes. Resize the image or raise the target if quality adjustment alone is insufficient.
No sign-up is required. The calculation or transformation happens in this browser tab and the result is available immediately.
BEFORE YOU RELY ON THE RESULT
Practical guidance
A 100 KB upload limit is strict enough that image dimensions often matter more than a small quality adjustment. This tool measures the generated file against 100 × 1,024 bytes.
How the target works
Metyris searches for the highest practical JPG or WebP quality below the target while keeping the current dimensions. If even the lowest tested quality is too large, the result is labelled as over target.
PNG is lossless and does not respond to a photographic quality slider in the same way. WebP or JPG is usually a better choice for a small photographic upload.
Protect readability
Check small text, signatures, document edges and fine lines at normal viewing size. If they become soft, return to the original, resize only as much as necessary, and try again.
The input limit is 30 MB and 40 megapixels. Browser memory can become the practical limit on older phones even below those caps.
Data removed during export
The browser creates a new image. Camera metadata, location fields and embedded color-profile information are not preserved. Transparent pixels become white when the output is JPEG.

Does the original file change?+
No. The result is a new download.
What happens to metadata?+
Canvas processing removes metadata and animated inputs become a still frame.
Is my content uploaded?+
No. Processing happens in this browser tab and the tool does not send your content to a server.
