How to use the photo and signature merger
Add your photo, press "Choose signature" and pick the signature image. It is placed under the photo on a white background; move it beside the photo or make it narrower if needed. Type the width and the KB limit from your form's instructions, then download the JPG.

About this tool
Some application forms take the photo and the signature as one upload: the photo on top, the signature underneath, in a single JPG under a size limit. Doing that in a phone gallery or a document editor is fiddly. Here you add the photo, choose the signature, and the two are set on a white background as one image.
The signature's width is measured against the photo's, so it can run the full width or sit narrower and centred. If your form states a pixel width for the combined image, type it and the whole picture is scaled to it. If it states a maximum file size, type that too, and the JPG quality is lowered just far enough to fit without changing the pixel size.
This page follows no particular form's rules, and it does not know what any form accepts. Every organisation sets its own sizes, layout and limits, and they change between notices. Read the instructions for your form and enter its figures. Nothing here cleans up a signature either: grey paper stays grey, so photograph the signature on plain white paper in good light and crop it close before adding it.
What you get
- Signature under the photo or beside it
- Signature width set against the photo
- Optional exact width in pixels
- Optional file size limit in KB
- White or any background colour

When to use the photo and signature merger
Forms that take one combined upload
Where an application portal has a single field for the photo and the signature together, the two are merged before uploading.
Passes and ID slips
A photo with the holder's signature beneath it, for a locally printed pass, a membership card or a record sheet.
Records kept by schools and offices
Staff and student files that hold the photograph and the specimen signature as one picture per person.
Signatory blocks for scanned documents
The signatory's photograph with the signature under it, as a single picture to attach to a scanned agreement.
What each setting changes
| Setting | What it does | Leave it when | Change it when |
|---|---|---|---|
| Where the signature goes | Under the photo, or to its right | The form shows the signature below | The form's sample shows them side by side |
| Signature width | Sets the signature against the photo's width | The signature should span the photo | The sample shows a smaller, centred signature |
| Width of the result | Scales the finished picture to a pixel width | The form gives no pixel size | The form states dimensions for the combined image |
| Largest file size allowed | Lowers the JPG quality until the file fits | The form sets no limit | The form rejects files over a stated size |
How it works
The photo is placed at its own pixel size and the signature is scaled to the share of the photo's width you chose, keeping its proportions; it is never made wider than the photo or, beside it, taller. The gap between them is a share of the photo's width. Both sit on a canvas filled with the background colour, white unless you change it. If you enter a width for the result, the finished canvas is scaled to that width as a whole, so the photo and the signature keep their relation to one another.
With a size limit entered, the JPG is encoded repeatedly at different qualities, a search of up to eight steps, and the highest quality whose file fits is kept. The limit is counted in bytes at 1000 to the kilobyte. The pixel dimensions are not reduced to meet the limit; if even the lowest quality is too large, the result note says so and a smaller width is the remedy. The photo and the signature are read in your browser and are not sent anywhere.
Common problems and how to fix them
- The signature is tiny under the photo
- The signature image has a lot of empty paper around it, so the ink is a small part of it. Crop it close to the signature first, then choose it again.
- There is a grey box around the signature
- That is the paper in the signature's own picture; it is not removed here. Photograph it again on white paper in even light, or scan it. Matching the background colour to the paper can hide a slight tint.
- The file is still over the limit
- At the current pixel size even the lowest quality is too big. Enter a smaller width for the result: halving the width cuts the file to roughly a quarter.
- The form rejects the image although the size is right
- Check the other requirements in its instructions: exact pixel dimensions, JPG and not PNG, and sometimes a minimum size as well as a maximum. This page cannot know them; they have to be entered as the form states them.
Frequently asked questions
What size should the merged image be?
Whatever your form's instructions say. There is no general answer and this page does not supply one. Look for the pixel dimensions and the maximum file size in the notice or beside the upload button, then type the width and the size limit here.
My signature has a grey or shadowed background. Can this page fix it?
No. The signature is placed as it is. Photograph it again on plain white paper in even light, without flash glare, and crop it close with the Image Cropper. A clean scan gives the best result.
How is the file size limit counted?
A kilobyte is counted as 1000 bytes, the stricter of the two definitions in use, so a file that fits here also fits a form that counts 1024 bytes to the kilobyte. Sizes shown on this page use 1024, so a file limited to 50 KB is displayed as about 48.8 KB.
Should I resize the photo and the signature first?
If the form gives separate sizes for each, yes: prepare each one with the Signature Resizer or the page for your exam, then merge them. If it gives only a size for the combined image, merging first and setting the width here is enough.
Is this an official tool for any exam or organisation?
No. It is a general tool, not connected to any examining body, government department or portal. It cannot tell you what a form will accept, and a file made here is only right for a form if you entered that form's own figures.
Can I put the signature above the photo, or add a name?
The signature goes under or beside the photo only. To print a name and a date on a photo, use Add Name and Date to Photo, then merge the result with the signature here.
Is my photo or signature uploaded anywhere?
No. Both files are opened and combined inside your browser, on your own device, and are not sent to a server.
