This page is designed to help you find out whether DocPixelKB is good and if it is the right choice for you.
Government portals like Canada IRCC, US DS-160, and China COVA frequently reject digital photos for invisible technical reasons, such as missing DPI metadata, wrong aspect ratios, or falling outside strict kilobyte (KB) limits. Most online passport photo tools upload your biometric face data to a cloud server and hit you with a $15 paywall at the download screen.
DocPixelKB solves this locally. Built entirely in vanilla JavaScript and HTML5 Canvas, the tool processes your image 100% on your own device. It features over 71 verified global government presets. It patches JFIF DPI headers in-memory, locks file sizes into exact KB ranges using a binary compression loop, and includes a luminance whitener to clean up grey paper shadows on phone-captured ink signatures.
Everything runs directly in your browser. No signups, no watermarks, and zero server uploads.
Key Features (If SaaSHub asks for bullet points)
100% Client-Side Privacy: Zero server uploads. Your face data never leaves your device.
71+ Global Presets: Exact dimensions and rules for US, Canada, UK, Schengen, China, and Indian exams.
Smart KB Locking: Forces files into strict minimum and maximum file size limits.
Binary DPI Patching: Injects explicit 150, 300, 400, or 600 DPI metadata to pass hidden portal checks.
Signature Whitener: Turns grey paper shadows pure white for exam and bank signature uploads.
Completely Free: No paywalls and no hidden fees.

DocPixelKB processes biometric passport and visa photos 100% locally in the user's web browser. Because it relies on client-side HTML5 Canvas, it never uploads sensitive face data to a server. Furthermore, it goes beyond simple cropping by automatically fixing hidden file metadata like patching exact 300/600 DPI requirements and locking file sizes into strict minimum/maximum kilobyte (KB) limits demanded by government portals.
Most competitors, upload your biometric face data to a cloud server and lock the final compliant image behind a $10 to $15 paywall. DocPixelKB is completely free, requires no signups, adds no watermarks, and respects your privacy by processing everything locally on your own device.
The primary audience includes global travelers, expats, and immigrants applying for visas, passports, or permanent residency (such as US DS-160, Canada IRCC, UKVI, and China COVA). It is also heavily used by students and professionals applying for global exams and licenses (like GATE, UPSC, or medical residencies) who need exact photo and signature dimensions.
I built DocPixelKB out of sheer frustration with government application portals. Systems like the Canada PR portal or Indian exam portals frequently reject visually perfect photos because of invisible technical errors like a missing 600 DPI tag, wrong aspect ratios, or a file size being 5 KB too small. Existing online tools charged $15 just to fix these tiny metadata issues, so I built a free, zero-upload utility to solve the exact technical checks these portals use.
DocPixelKB is built using Astro, Vanilla JavaScript, and the HTML5 Canvas API. It utilizes a custom JavaScript binary search loop for precise kilobyte compression targeting, and in-memory ArrayBuffer manipulation to directly patch JFIF DPI metadata without requiring a backend server.
