Can I join front and back sides of an ID card?

Yes! Use our 'Horizontal (Side-by-Side)' mode. Upload the front image and then the back image. The tool will perfectly align them into a single horizontal strip, making it easy to share ID proofs.

Is there a limit on file size for merging?

Our tool supports images up to 20MB per file. Since processing happens on your local device memory, larger files are processed instantly without the lag of uploading to a server.

Will the quality of my images decrease?

We use high-fidelity canvas rendering to ensure that your photo and signature remain sharp. The output is saved in a high-quality JPEG format to balance file size and clarity.

The Easiest Way to Join Photos & Documents

In many online application processes, you are limited by the number of files you can upload. For instance, a portal might only allow one attachment for "Identity Proof" or "Applicant Identification." This is where merging images becomes essential. By combining your passport photo and signature into a single file, you ensure that you comply with portal restrictions without compromising on clarity.

Our Merge Images tool is a specialized utility that removes the need for complex graphic design software. It is optimized for the specific aspect ratios used in official documentation, ensuring that your signature remains legible and your photo remains undistorted.

Common Use Cases

Govt Job Applications: Place your signature below your photo as per UPSC, SSC, and Banking exam mandates.
ID Cards: Join front and back views of Aadhaar, PAN, or Driver's Licenses for easier sharing.
School/College Admissions: Bundle required photo proofs into a single manageable file.
Professional Certification: Merge proof of completion with your profile photo for verification.

Privacy That Matters

When you deal with photos and signatures, privacy is not just a preference—it is a requirement. Most "free" online tools harvest your data to build datasets or target ads. Simple Compressor operates on a different philosophy. Because we use WebAssembly and the Canvas API to process everything on *your* CPU, we never even see your documents. Your files never touch our servers, making this the safest tool for sensitive document merging.
