How this tool works

What it does

Compresses an image toward 150 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 150 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 150 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 150 KB?

No. The tool compresses toward 150 KB and reports the size it actually reaches. It keeps the largest result at or under 150 KB when it can, and tells you if the smallest it can reach is still over.

What if my image will not reach 150 KB?

If 150 KB is hard to reach at full size, reduce the width or scale. The panel always shows the closest achievable size and flags whether it is over 150 KB.

Are my files uploaded when compressing to 150 KB?

No. Compression to 150 KB runs in your browser, so the file never leaves your device.

Does compressing to 150 KB change my image format?

When producing a 150 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 150 KB?

If the tool re-encodes the image to reach 150 KB, it strips embedded metadata such as EXIF and GPS, which the panel notes. If the original is kept because it is already under 150 KB, its metadata is unchanged.
