How this tool works

What it does

Compresses an image toward 5 KB by trying browser-supported encoder settings and, if needed, reducing dimensions, then reports the achieved size. It keeps the largest result at or under 5 KB when it can, otherwise the closest and marks it over target.

Format and transparency

Keeps JPG, PNG, or WebP where possible and converts HEIC, TIFF, SVG, and GIF to JPG. JPG fills transparent areas with your chosen background color.

Privacy

The image is processed on your device to reach 5 KB. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata. Your files are never sent to imgtoolsbase or any other server.

Frequently asked questions

Will my image be exactly 5 KB?

No. The tool compresses toward 5 KB and reports the size it actually reaches. It keeps the largest result at or under 5 KB when it can, and tells you if the smallest it can reach is still over.

What if 5 KB is too small for my image?

Very small targets like 5 KB are hard for detailed photos. Lower the dimensions, or accept the closest size the panel reports as the smallest practical result.

Are my files uploaded when compressing to 5 KB?

No. Compression to 5 KB runs in your browser, so the file never leaves your device.

Does compressing to 5 KB change my image format?

When producing a 5 KB file it keeps JPG, PNG, or WebP where it can; HEIC, TIFF, SVG, and GIF are saved as JPG, and animated GIFs become a single still frame. JPG has no transparency, so transparent areas use the background color you pick.

Is EXIF and GPS data removed when compressing to 5 KB?

If the tool re-encodes the image to reach 5 KB, it strips embedded metadata such as EXIF and GPS, which the panel notes. If the original is kept because it is already under 5 KB, its metadata is unchanged.
