Compress PDF for RRB Application Online
Railway recruitment through the RRBs: whether it is NTPC, Group D, ALP, or technician posts: begins with an online application that wants scanned documents. Alongside your photo and signature, you will typically upload education certificates and, where applicable, category and experience proofs as PDF files.
Shrinklyy compresses those PDFs right in your browser, free and without any sign-up, so every certificate fits the form and stays perfectly legible for the recruitment process.

Why it matters
Why PDF size matters
RRB applications are processed through regional portals under heavy load. Size matters more than you might think.
Heavy server traffic
Tens of lakhs of candidates apply in the same window. Smaller files transfer faster and are less likely to fail under load.
Per-file limits
RRB portals state maximum sizes for each uploaded document. Files beyond the limit are rejected by the form itself.
Certificate variety
Education, category, and experience certificates each arrive in different sizes and scan quality. Standardising them saves time.
When you need it
Common situations
Where RRB applicants run into file size trouble most often.
Educational qualification proofs
The minimum-qualification marksheet is required for every RRB post. Text-heavy marksheets compress exceptionally well.
Category certificate uploads
Candidates under reserved categories upload caste or income certificates, often with dense text and official stamps.
Experience certificates
Posts requiring experience ask for employer certificates. These are often long documents that compress cleanly.
Mobile-captured documents
Many applicants photograph their certificates with phones. Camera-captured PDFs are large and respond brilliantly to compression.
Application fee receipts
Exemptions and payment proofs sometimes need uploads too. A compact receipt is one less thing to worry about.

Practical advice
Helpful tips before you upload
A few minutes of preparation prevents the classic RRB upload failures.
Follow your regional RRB's instructions
Each railway recruitment board publishes its own notification. That is the authoritative list of documents, formats, and sizes.
Check marksheet legibility after compression
Marks and stamps must remain readable. After compressing, zoom into the file and check the important fields.
Keep photo and signature separate
Photos and signatures are usually uploaded as images with their own requirements. Do not bundle them into certificate PDFs.
Test the upload early
Within the application window, try uploading one document as soon as the portal opens. Fix any issues before the deadline rush.
Store originals for verification
The uploaded documents are cross-checked with originals at later stages. Keep both the hard copies and clean scans safe.
FAQ
Frequently asked questions
Common questions from RRB applicants about PDFs and uploads.
Typically a photo, signature, and certificates like education qualification proofs, plus category or experience certificates where applicable. The notification for your post lists the exact requirements.
Rejections usually come from an oversized file, a wrong format, or a file that is damaged. Compress with Shrinklyy, confirm the file opens, and upload again.
Yes, all of them, free of charge. Preparing every certificate in advance means the application itself becomes a short task.
The later stages verify content against your originals. Compression does not affect acceptance as long as every detail is legible.
With Shrinklyy, your files are processed entirely in your browser and never leave your device: there is no server upload at all.
Yes. Since the file never leaves your device, even a very slow connection is fine: the compression itself runs on your own hardware.
No account, no email, no payment. Open the tool, compress, download, and move on to the form.
