Compress an image to 5KB
Many upload forms reject a photo that is even slightly over the limit. This tool compresses a JPG, JPEG or PNG image to about 5KB. It is commonly used for very small thumbnails and portals that only accept tiny signature files.
5KB is a very small file size. A large camera photo has to lose a lot of detail to fit, so crop the picture or reduce its pixel size first for a cleaner result.
How to use this tool
- Upload the photo or scanned image from your phone or computer.
- Check that the target file size is set to 5 KB. You can type another value if your form asks for a different size.
- Click Compress & Download and upload the saved file to your form.
Frequently asked questions
How do I reduce a photo to 5KB?
Upload the photo, keep the target at 5 KB and click Compress & Download. The saved file will be very close to 5KB. If your form is strict about the limit, set the target a few KB lower.
Will the photo look blurry after compressing to 5KB?
Some loss is normal at 5KB. Start with a tightly cropped image around 200 to 400 pixels wide and the result will be much sharper.
Is my photo uploaded to a server?
No. The image is compressed inside your browser and the file stays on your device.
