Protect your privacy and image quality with free online tools. Discover more about image metadata and AI content tags. Canonical URL: https://msbsu.com/posts/how-facebook-detects-ai-generated-images-how-to-remove-image-metadata English বাংলা Have you ever edited an image using AI and uploaded it to Social Media? Have you noticed that when you generate / edit an image using AI and upload it to Facebook directly from the same device, Facebook adds an AI Content tag to that image, which you cannot remove? So, how does the mechanism behind this actually work? — Nothing complicated, it's simply because of Image Metadata. Actually, after generating an image, ChatGPT or Gemini adds its own invisible signature to it. You might not be able to see it in the image itself, but if you open the image's Raw Code in an IDE, you can see those signatures. These are called Image Metadata, which contains all sorts of information, such as which camera was used to take the photo, where it was taken, what settings were used, etc. So, if you take an image generated / edited using ChatGPT or Gemini and remove that Metadata, will Facebook still be able to add the AI Content tag? — Absolutely not. Then how can you do this easily? — You may have noticed that if you generate an image using AI and send it to someone through WhatsApp or Messenger, then download it from there and post it, the AI Content label doesn't appear. This is because Social Messaging channels degrade your image quality to save their server storage, and they also remove the Metadata to reduce the image size as much as possible. So, this can be one solution, but the problem is that the Image Quality drops in the process. So, are there any other solutions? — Yes, there are many free and open-source tools available that allow you to remove Image Metadata easily without reducing Image Quality. I also created a similar tool where you can easily remove / edit Metadata. Link: https://msbsu.com/tools/img-meta There are also several other useful tools available here that you can explore, including PDF editing tools (PDF Converter, PDF header & Footer editing tool, PDF watermark tool, PDF password encryption tool, etc.), Designed QR Code Generator, Portfolio Generator, Image/Video Tools, etc. You can also save my website as an app if you want (you will see an Install as App popup when you visit). Besides, the tools can be used easily on both laptops and mobile devices. All files remain on your device, so you don't have to spend even a second uploading/downloading PDFs of several gigabytes. কখনও কি AI দিয়ে কোনো ছবি এডিট করে Social Media তে আপলোড করেছেন? খেয়াল কি করেছেন যে কোনো ছবি AI দিয়ে বানিয়ে / এডিট করে ওই ডিভাইস থেকেই Facebook এ আপলোড করলে Facebook ওই ছবিতে AI Content ট্যাগ লাগিয়ে দেয়, যেটা আপনি রিমুভ করতে পারেন না? আসলে এর পেছনে কেমন মেকানিজম কাজ করে? — কোনো জটিল কিছু না, শুধুমাত্র Image Metadata এর জন্য দায়ী। আসলে ChatGPT অথবা Gemini কোনো ছবি তৈরির পর ওই ছবিতে নিজের অদৃশ্য সিগনেচার বসিয়ে দেয়, যেটা হয়তো ওই ছবিতে দেখা সম্ভব না, কিন্তু কোনো IDE তে ওই ছবির Raw Code ওপেন করলে সেগুলো দেখা যায়। এগুলোকেই বলে Image Metadata, যেখানে ওই ছবি কোন ক্যামেরায় তোলা, কোন লোকেশনে তোলা, কেমন সেটিংস দিয়ে তোলা ইত্যাদি সকল তথ্য থাকে। তাহলে যদি ChatGPT বা Gemini থেকে তৈরি / এডিট করা ছবিটি নিয়ে আপনি সেই Metadata রিমুভ করে দেন, তাহলে কি Facebook আর AI Content ট্যাগ লাগাতে পারবে? — অবশ্যই না। তাহলে কীভাবে সহজে এই কাজটি করা যায়? — খেয়াল করবেন যদি AI দিয়ে ইমেজ তৈরি করে সেটা কাউকে WhatsApp বা Messenger এ পাঠান, তাহলে সেখান থেকে নামিয়ে নিয়ে পোস্ট করলে কিন্তু AI Content লেখা ওঠেনা, কারণ এক্ষেত্রে Social Messaging চ্যানেলগুলো তাদের সার্ভার স্টোরেজ বাঁচাতে আপনার ইমেজ কোয়ালিটি degrade করে দেয়, সাথে Metadata গুলোও রিমুভ করে দেয়, যাতে করে ছবির সাইজ কমে আসে সর্বোচ্চ পর্যায়ে। তো এটা একটা সমাধান হতে পারে, কিন্তু এক্ষেত্রে Image Quality ড্রপ করতেসে। তাহলে এখন আরও কি সমাধান আছে? — হ্যাঁ, Image Quality ড্রপ না করে যাতে সহজে Image Metadata রিমুভ করা যায় এর জন্য অনেক ফ্রী ও ওপেন সোর্স টুল আছে। আমিও এরকম একটা টুল তৈরি করলাম, যেখানে সহজেই Metadata রিমুভ / এডিট করা যাবে। লিংক: https://msbsu.com/tools/img-meta এখানে আরও বেশ কিছু প্রয়োজনীয় টুল আছে, এক্সপ্লোর করে দেখতে পারেন, PDF এডিটিং টুল (PDF Converter, PDF header & Footer editing tool, PDF watermark tool, PDF password encryption tool ইত্যাদি), Designed QR Code Generator, Portfolio Generator, Image/Video Tools etc. চাইলে আমার ওয়েবসাইটটি অ্যাপ হিসেবে সেভ করে রাখতে পারেন (ভিজিট করলেই Install as App পপআপ দেখতে পারবেন)। তাছাড়া টুলগুলো ল্যাপটপ/মোবাইল সবখানেই সহজে ব্যবহার করা যায়, সব ফাইল আপনার ডিভাইসেই থাকে, তাই কয়েক জিবি পিডিএফ আপলোড/ডাউনলোড করতে এক সেকেন্ডও সময় লাগে না।
