What are secret file size limits?
File size depends on your cover image's resolution and color depth, such as larger, more detailed images hide more data. Quantumography accepts JPEG, JPG, and PNG cover images, and calculates available capacity automatically before you upload, so you always know how much you can conceal. For most standard photos, you can safely hide documents, PDFs, or small archives without visibly altering the image's appearance or quality.
How does end-to-end encryption work?
Your file is encrypted locally before it's ever embedded into the cover image, using your password as the decryption key. Neither the image nor the encrypted data is readable without that password. This end-to-end approach means only you and whoever you share the password with can ever unlock the hidden contents.
How do I decode a file that has been encrypted?
Open Quantumography, upload the image containing your hidden file, and enter the password you set during encryption. The application extracts and decrypts the concealed data automatically, restoring your original file exactly as you hid it. Without the correct password, the hidden contents remain mathematically inaccessible, even to Quantumography itself.
Are secret files stored on Quantumography's database?
No. Quantumography does not store your original files, cover images, or passwords on any server or database. All hiding and decoding happens within your session, and once you download your image, nothing remains on our systems. Your privacy depends on you keeping the image and password safe, not on us holding a copy.
What are the price packages for encrypting bigger files?
Quantumography offers a free tier for everyday file sizes, ideal for documents, PINs, and personal records. For larger files, such as high-resolution archives or bulk business data, upgraded plans unlock higher capacity limits and priority processing. Visit the pricing page within the application for current package details and to choose the plan that fits your needs.
