GATE Certificate Upload Requirements.
When registering online for the Graduate Aptitude Test in Engineering (GATE), candidates claiming fee concession or reservation must upload supporting certificates (such as Category or PwD status) in PDF format.
The official requirements state that these PDFs must be between 10 KB and 300 KB. Legibility is crucial: names, dates, and issuing officer signatures must remain completely readable.
Do not password-protect your PDFs, as the GATE verification team will be unable to open them, leading to registration defects.
Your files stay on your device.
Your document never leaves your browser. Compression runs 100% client-side using browser APIs — no server uploads, no data collection, no account required.
Frequently Asked Questions.
For category, PwD, and scribe certificates, GATE requires PDF files to be sized between 10 KB and 300 KB. The text must remain legible.
Our browser-based engine applies a specialized downsampling algorithm that preserves fine black text while compressing the background, keeping signatures and seal numbers crisp.
No, GOAPS (GATE Online Application Processing System) will reject password-protected PDF files or flag them with a 'Defect Status'. Ensure your file is unencrypted before compressing and uploading.
Check two things: 1) Ensure the file size is strictly under 300 KB (target 250 KB with Zcompressor). 2) Ensure the PDF does not contain special characters or spaces in its filename (use names like category_certificate.pdf).
Yes. Zcompressor runs completely client-side in your web browser memory. Your documents never reach any server or third-party database.
