Compress a signature to 10–20 KB
Get a photo or scan of your signature between 10 and 20 KB, the range most application forms ask for. Small signatures are brought up to the minimum, so the form takes them.

How it works
Compress in three steps
- 1
Photograph or scan your signature on white paper and drop the image in.
- 2
Tap Crop to frame the signature. Graviton keeps the JPG between 10 and 20 KB.
- 3
Download it and upload it to your form.
Tips for a clean signature
Sign with a dark pen on plain white paper, photograph it in daylight without shadows, and crop close to the signature before compressing. Less empty paper means more detail fits in 20 KB.
Different limit on your form?
Change the maximum and minimum size in the settings to match your form. A signature that comes out smaller than the minimum gets a comment no viewer shows, which brings the file up to size without changing the picture.
Frequently asked questions
Which format do forms accept?
Almost all accept JPG or JPEG, which is what Graviton produces here. Check your form in case it asks for something else.
Are my images uploaded?
No. Graviton converts and compresses inside your browser, so your images never leave your device. Nothing is sent while you compress. When you download, the browser sends only a one-way fingerprint of the image, so the download can be counted and approved. Graviton stores none of it.
Can I do my photo too?
Yes. Use the exam photo compressor for photos, which keeps them between 20 and 50 KB, or the IBPS and PAN card tools for those forms’ exact sizes.
Is it free?
Yes. Compressing and converting are free and unlimited, with no account needed. Downloading needs a free account, which includes 3 downloads a day with every format and setting. Pro removes the daily limit.
