Compress an image toward 40 KB and see the size achieved. Everything runs locally in your browser.
Compresses an image toward 40 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 40 KB when it can, otherwise the closest and marks it over target.
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.
The image is processed on your device to reach 40 KB. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata. Your files are never sent to imgtoolsbase or any other server.
This tool compresses an image toward 40 KB, entirely in your browser. It tries browser-supported encoder settings and, when needed, reduces the dimensions, keeping the largest result at or under 40 KB when it can.
It reports the size actually achieved. If 40 KB cannot be reached at the current dimensions, the panel shows the closest size and flags it as over target, so you can resize and try again.
Compresses toward 40 KB and reports the achieved size, keeping the largest result at or under target when it can.
If the image cannot reach 40 KB, the panel shows the closest size and flags it as over target instead of pretending it succeeded.
When targeting 40 KB it outputs the same format where possible and converts HEIC, TIFF, SVG, and GIF to JPG, which it discloses.
Compression to 40 KB happens entirely in your browser; nothing is uploaded to a server.
Hit a 40 KB cap on application and registration forms.
Serve a lighter 40 KB image to improve load time.
Keep an attachment around 40 KB so it sends easily.
Store a smaller 40 KB copy without keeping the full-size original.
No. The tool compresses toward 40 KB and reports the size it actually reaches. It keeps the largest result at or under 40 KB when it can, and tells you if the smallest it can reach is still over.
If 40 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 40 KB.
No. Compression to 40 KB runs in your browser, so the file never leaves your device.
When producing a 40 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.
If the tool re-encodes the image to reach 40 KB, it strips embedded metadata such as EXIF and GPS, which the panel notes. If the original is kept because it is already under 40 KB, its metadata is unchanged.
