Resize your signature to 140×60 under 20 KB
Exam and government application portals typically require a scanned signature of exactly 140×60 pixels at 10–20 KB. FormFit's signature preset crops, resizes and compresses your signature photo to that exact specification in one step — entirely in your browser, so your handwritten signature is never uploaded to anyone's server.
How to prepare a signature for an online form
- Sign with a black or dark blue pen on plain white paper.
- Photograph or scan it straight-on in good light, cropping close to the signature.
- Drop the image into FormFit — the Signature preset resizes it to exactly 140×60 pixels and compresses it under 20 KB.
- Check the green PASS badge and download the ready-to-upload file.
Why signatures get rejected
The two usual causes are wrong dimensions and oversized files — a phone photo of a signature is thousands of pixels wide and several megabytes. Portals also reject signatures that don't fill the frame: FormFit center-crops to the 140×60 shape, so crop your photo close to the signature first for the best result. If your portal asks for a different spec, use the custom option on the main tool to set any KB size and dimensions.
Frequently asked questions
Is it safe to process my signature online?
With FormFit, yes — unlike typical compressor sites, your signature is never uploaded. All resizing and compression happens inside your own browser, and the tool works even with your internet disconnected.
My portal asks for a different signature size. Can I change it?
Yes. Use the Custom preset on the main tool to enter any maximum KB size plus exact width and height in pixels — for example 300×80 under 30 KB.
Why does my signature look stretched or cut off?
The preset center-crops to a 140×60 shape, which is much wider than it is tall. Crop your source photo close around the signature (a wide strip, not a square) before dropping it in, and it will fill the frame naturally.
Also preparing the photo? Most portals pair the signature with a 200×230 photo under 50 KB — or see all size targets on the main tool.
