How do I merge my photo and signature online for free?

Upload your photo and your signature, crop either one if needed, set your required width, height, and DPI, then tap Merge & Download. The whole process takes under a minute, needs no signup, and never adds a watermark.

What size should my combined photo and signature be for SSC, UPSC, Railway, or Banking exams?

It varies by year and exam body, so always check the latest official notification first. As a general reference, photo dimensions commonly range from around 200×230px up to 450×450px, with a signature strip roughly 40–80px tall added below or overlapped on top — once you have the exact numbers, just type them into Set Width & Height.

Can I compress the merged image to an exact size like 20KB or 50KB?

Yes. Turn on Compress image to specific size, enter your target — for example 50 — and the tool automatically adjusts quality until the final JPEG lands at that exact KB size.

What does the Overlap feature do?

When enabled, your signature is placed directly on the lower portion of your photo, stamp-style, instead of sitting as a separate strip below it. Leave it off for the standard stacked layout most government and exam portals expect.

Is it safe to upload my signature and passport photo here?

Yes. Nothing is actually uploaded — your photo and signature are merged, cropped, and compressed entirely inside your own browser using HTML5 Canvas. Your files are never sent to, or stored on, any server.

Which file formats can I use, and what do I get back?

You can upload JPG, JPEG, PNG, WebP, or BMP files for both your photo and signature. The merged output is always delivered as an optimized JPEG, ready to upload to any portal.

Will resizing or compressing reduce the quality of my photo or signature?

Barely, if at all. Canvas-based resizing preserves detail far better than a quick screenshot resize, and the compression engine only reduces quality as much as necessary to hit your target KB. Starting from a clear, high-resolution scan gives the best final result.

What DPI should I use?

200 DPI is a safe default for almost every online form upload. Switch to 300 DPI only if the portal specifically asks for print-quality output, or if you plan to get a physical copy printed.

Why do exam portals reject photo-and-signature uploads?

The most common reasons are a signature touching the edge of the photo, the wrong aspect ratio, a file size outside the allowed KB range, or a dark or busy background behind the signature. Zoom in to 100% and compare against the official sample before you submit.

Does this tool work on mobile phones?

Yes. You can select your photo and signature straight from your phone's gallery, crop them with a fingertip, and download the merged file directly to your device — no app install needed.

Is there a limit on how many times I can use this tool?

No. It is completely free, works without any account or login, and never adds a watermark to your downloaded image, however many times you use it.

Overview

What is a Photo & Signature Merger?

Photo & Signature Merger: A browser-based tool that takes two separate image files — your passport-style photograph and a scanned or photographed signature — and combines them into one correctly proportioned file, formatted exactly the way exam boards, banks, and admission portals expect for a single combined upload.

Creates the standard photo-plus-signature format instantly, without Photoshop, Lightroom, or any design experience.
Merges on an HTML5 canvas for pixel-accurate results, so there is no visible quality loss between your source images and the final file.
Keeps your passport photo and signature 100% private by processing everything locally in your browser — nothing is ever uploaded to a server.

How to merge photo and signature online

1. Upload Your Photo and Signature

Tap Select Photo and Select Signature to add your passport-style photograph and your signature — JPG, JPEG, PNG, WebP, and BMP files up to 50MB combined are all supported.

2. Crop and Adjust Each Image

Use the floating Crop button to trim background from either image on its own. Turn on Overlap if you want your signature stamped directly onto the photo instead of placed below it, and adjust its width to fit.

3. Set Exact Dimensions and DPI

Switch between Cm, Inch, or Pixel and enter the exact width, height, and DPI your exam, bank, or admission portal specifies — most official notifications list this clearly, right down to the pixel.

4. Hit Your Target KB and Download

Turn on Compress image to specific size, enter your required KB (say, 20 or 50), add a border if you need one, then tap Merge & Download to save your finished file instantly.

Advanced features for perfect alignment

Smart Overlap Module

Place your signature directly over the lower portion of your photo, stamp-style, with adjustable width — the layout an increasing number of digital KYC and banking forms now ask for.

Target KB Compression

Enter any target file size — 20KB, 50KB, 100KB, whatever your portal demands — and the engine steps through quality levels automatically until it lands on that exact number.

Precision Dimension Control

Switch between centimeters, inches, or pixels and set DPI manually, so your output matches an exam notification's requirements to the pixel, not just an approximation.

Fullscreen Smooth Cropping

Drag the crop box or resize it from any corner to remove stray background from your photo or tidy up a signature scan — just as smooth with a fingertip on mobile as with a mouse.

Automatic Border Addition

Add a clean, uniform border around your finished composite in a single tap — useful for portals that ask for a bordered photo, or simply for a sharper finished look.

100% Client-Side Privacy

Every crop, resize, overlap, and compression step happens on your own device using HTML5 Canvas — your photo and signature are never sent to a server, so there is nothing to leak, store, or delete later.

Your passport photo and signature are some of the most sensitive files you own, which is exactly why this Merge Photo and Signature tool is built on a strict zero-upload architecture.

Every crop, overlap, resize, and compression step runs entirely inside your browser's own memory — your images are processed on your device and never transmitted anywhere else.

HTML5 offscreen canvas processing, done locally on your device.
Web Worker-based compression, so large images never freeze your browser.
No cloud storage, no API transmission, and no copy of your files ever kept.

Key Terms Explained

DPI (Dots Per Inch)

A measure of image density used when working in centimeters or inches — the higher the DPI, the more pixels are packed into each inch, and the sharper the result looks when printed. Most online form uploads work fine at 200 DPI; choose 300 DPI if you also need a physical printed copy.

Target KB Compression

The process of shrinking a file to a specific kilobyte size — say, exactly 50KB — while keeping as much visual clarity as possible. This matters for exam and banking portals that reject uploads outside a strict size range.

Passport-Size Photo

A front-facing photograph on a plain, light background, typically sized around 35×45mm or 2×2 inches — the base format most Indian government and international forms expect before it is merged with a signature.

Signature Overlap

A layout where the signature sits directly on top of the lower portion of the photo, stamp-style, instead of appearing as a separate strip underneath it. A few digital forms ask for this; most exam boards still prefer the signature stacked below the photo, so check the notification first.
