PhotoKB.net is a free set of online tools that help students, job seekers and applicants prepare photos, signatures, images and PDF documents so they meet the exact upload rules of online application forms. This page explains who we are, what we do, and how we work.
Why PhotoKB exists
Every year, millions of people in India fill online forms for competitive exams, government jobs, college admissions, scholarships and identity services. Almost every form has strict upload rules, for example "photo between 20KB and 50KB, 200 × 230 pixels, JPG only" or "signature 10KB to 20KB". A small mistake can stop an application at the last step, often close to the deadline.
Most people do not have photo-editing software, and many general image compressors do not understand these rules. They ignore minimum sizes, stretch faces, or upload personal documents to unknown servers. PhotoKB was created to solve exactly this problem: simple tools that follow form rules, and that keep your files private.
What we offer
- Photo tools: resize photos to 20KB, 50KB, 100KB or 200KB, make passport-size photos, and add name and date to a photo.
- Signature tools: crop, clean and compress signatures to 10KB, 20KB or 50KB, with presets for common exams.
- Image tools: resize by pixels, cm or inches, crop to any ratio, make square images and convert to JPG.
- PDF tools: compress PDFs to 100KB, 200KB or 500KB, convert images to PDF, merge PDFs and prepare documents for application forms.
All tools are free to use, need no account, and add no watermark. You can see the full list on our home page.
Your files stay on your device
Privacy is the core of how PhotoKB is built. Our tools run inside your web browser. When you choose a photo, signature or PDF, it is processed on your own phone or computer. It is not uploaded to our server, and we cannot see, store or share it. This makes PhotoKB safe for personal documents such as ID proofs, certificates and marksheets. You can read more in our Privacy Policy.
How we create and review content
Each tool page includes a guide that explains file sizes, pixel dimensions and common mistakes in plain language. Our editorial approach is simple:
- Practical testing: we test every tool with real phone photos, scanned signatures and PDF documents before publishing or updating it.
- Official sources first: where we mention exam or portal rules, we base them on publicly available official notifications and link to the official website wherever possible.
- Clear limits: rules change often, so we clearly ask users to confirm the latest requirements with the official authority.
- Regular updates: we review pages when common requirements change and show a "last updated" date on each tool.
Who we are
PhotoKB is built and maintained by the PhotoKB Team, a small independent team based in India with experience in web development, digital marketing and helping applicants with online forms. We are not connected to any government department, commission, university or exam conducting body. Our Disclaimer explains this in more detail.
How PhotoKB is funded
To keep the tools free for everyone, PhotoKB may show advertisements, including ads served by Google AdSense. Advertising never affects how a tool works or what our guides recommend. We do not sell personal data, and ads are kept separate from the tool area so they do not get in the way of your work.
