Remove background

Erase the background around each card side after perspective correction. Best for clean, isolated cards — adds extra processing time per side.

How It Works

Process your images in three simple steps

Upload Both Sides

Drop in photos of your ID card's front and back, or use your camera to capture each side directly. Supports JPG and PNG images from any device — phone, tablet, or desktop.

Auto-Crop and Clean Up

Each side is scanned for corners, cropped automatically, and flattened with perspective correction so a slightly tilted photo comes out straight. You can also remove the background for a clean white finish before finalizing.

Download as PDF or ZIP

Export a single PDF with both sides on one page — ready for KYC uploads, bank forms, or official submissions. Prefer separate files? Download the front and back as a ZIP instead. Nothing is saved on any server.

Why Choose Imresizer?

Fast, secure, and completely free image resizing

Front and Back on One PDF
Both sides of your ID card are combined into a single, clearly labeled PDF page. No need to juggle two separate files when submitting documents to banks, embassies, or HR departments.
Auto Corner Detection
The tool finds each card's edges and crops it automatically — no dragging handles around. If the detection misses by a hair, you can nudge the corners manually before applying the crop.
Perspective Correction
Photos shot at a slight angle come out flat and rectangular. The perspective fix straightens tilted captures so your ID looks like it came off a proper scanner, not a phone held at arm's length.
100% Private
Your card images never touch a server. The cropping, perspective fix, background removal, and PDF export all happen locally in your browser — so your ID stays on your device, full stop.
Background Removal Built In
Strip the desk, hand, or clutter out of the shot with on-device AI. The card sits on a clean white background in the final PDF, which is what most KYC portals and visa applications expect.
One-Tap PDF Export
Generate a print-ready PDF with the front and back side by side in seconds. It's the format most banks, employers, and government portals accept for identity verification.
Fast, No Waiting
Merging runs in your browser with no server round-trip. From upload to download typically takes under 30 seconds — even on a slow connection, since nothing is being transmitted.
Any Device, Any Browser
Use it from your phone camera roll or directly from your desktop. The layout adjusts to your screen so uploading and previewing both sides stays clear on every device.

What Our Users Say

Trusted by thousands of users worldwide since 2015

“

I had to submit my ID for a bank account online. This merged the front and back into one PDF in about 20 seconds. Exactly what I needed.

“

The auto corner detection nailed the crop on the first try. I was ready to fix it manually and didn't have to touch a thing.

“

Finally a tool that doesn't ask me to create an account just to combine two photos. Quick and clean.

“

The privacy angle was the reason I tried it. My ID images stay local — that matters when you're dealing with identity documents.

“

Used it for a visa application that required both sides of my national ID on a single page. The perspective correction fixed my crooked phone shots nicely.

“

Background removal was a surprise bonus. Clean white card on a white PDF page — looked way more official.

“

The output PDF looks like it came from a real office scanner. Very clean layout with the front and back clearly labeled.

“

Saved me a trip to the library just to use their scanner. My phone photos of the card came out surprisingly well.

Frequently Asked Questions

Everything you need to know about image resizing

What does 'merge ID card front and back' mean?

It means combining photos of both sides of your ID card into a single file — usually a PDF with the front on one half and the back on the other. This is the format most banks, employers, and government portals ask for when you submit identity documents digitally.

How do I merge the front and back of my ID card?

Upload or capture a photo of each side using the two upload boxes. The tool auto-detects the corners, crops each side, and corrects perspective automatically. Then click Download to get a combined PDF or a ZIP with separate image files — the whole process takes under a minute.

How does the auto corner detection work?

After you upload a photo, the tool analyzes the image to find the four corners of the card and crops along those edges. If the detected corners are off — because of a busy background or uneven lighting — you can drag them to the correct spots before the crop is applied.

What is perspective correction and why does it matter?

Perspective correction flattens a photo taken at an angle so the card appears as a clean rectangle. Without it, the top or bottom edge often looks longer than the other, which is a common reason official portals reject ID uploads. The fix happens automatically after cropping.

Can I remove the background from the ID card photo?

Yes. After cropping, you can apply on-device background removal to isolate the card on a clean white background. This is handy when the original photo shows your desk, hand, or a cluttered surface that you don't want appearing in the final PDF.

What ID card types does this tool support?

Any card-sized document works: national ID cards, driver's licenses, student cards, employee badges, and business cards. The tool uses standard card dimensions for cropping, so the output looks consistent regardless of which card you're scanning.

Is my ID card image uploaded to a server?

Nothing is uploaded. The corner detection, perspective fix, background removal, and PDF generation all run locally in your browser using client-side processing. Your card photos stay on your device from start to finish — no account, no cloud storage, no server ever sees your images.

What file formats can I download?

Download a single PDF with both sides on one page, which is the most widely accepted format for identity submissions. Alternatively, grab a ZIP containing the front and back as separate JPEG or PNG images if you need the files individually.

Can I use my phone camera to capture the ID card?

Tap the Camera button on either upload box to open a live viewfinder with a card-shaped alignment guide. Hold your card steady inside the outline and tap capture — the image is added automatically and runs through the same auto-crop and perspective fix as uploaded photos.

Do I need to create an account or pay?

The tool is completely free and requires no account or login. You can merge as many ID cards as you need without any restrictions or watermarks on the output.

Why does my card still look crooked after auto-crop?

Perspective correction works best when all four corners are visible and the background contrasts with the card. If one edge is cut off or blending into a similar-colored surface, drag the corner handles to the correct positions manually — the tool will re-apply the perspective fix using your adjusted corners.

Can I merge two different ID cards into one PDF?

The tool is designed for the front and back of a single card on one page. If you need to combine two different cards or more than two images into a multi-page PDF, the Scan Document tool is the better fit.

Does this work on iOS and Android?

The tool runs in any modern mobile browser. On iOS and Android you can either pick photos from your camera roll or tap the camera button to capture the card directly. No app download is required.

Is the merged PDF accepted for KYC and official submissions?

The PDF output is a standard, unencrypted PDF with both sides clearly labeled — the same format most banks, government portals, and HR systems request. If an institution has specific requirements like file size limits or color vs. black-and-white, check those before submitting.
