Compress Certificate for Admission Upload
Caste certificates, income certificates, and bonafide certificates are typically scanned at high resolution — producing 2–6MB files. College admission portals (DU, JOSAA, CSAB, state portals) reject anything above 100–200KB. Compress in seconds, keep the text crisp, and never miss a deadline over a file size error.
What You Need to Know
Indian college admission portals require multiple document uploads — caste certificate, income certificate, domicile certificate, bonafide, migration certificate, and more. Each has its own KB limit, usually between 100KB and 500KB. Missing an upload or getting rejected due to file size at the final step of a lengthy form is a common and avoidable problem. Compress each document type once, label the files clearly, and keep them ready before you start filling the form.
How It Works
Step 1: Open the compressor
Click below — use the custom compressor to set the exact KB your portal requires.
Step 2: Upload your certificate scan
Any JPEG, PNG, or WebP image up to 25MB — scanner output or phone photo both work.
Step 3: Set the target size
Check the portal's upload section — limits are usually printed next to the upload field. Common: 100KB or 200KB.
Step 4: Preview and download
Confirm the text is readable in the preview, then download and upload to the portal.

Pro Tip
Before opening the admission portal, compress all documents in one sitting: caste certificate, income certificate, marksheets (10th, 12th), and photo. Label each file clearly (e.g. 'caste_cert_100kb.jpg'). Admission portals have session timeouts — having all files ready means you complete the form in one go without interruption.
Frequently Asked Questions
What size should I compress my certificates to?
JOSAA / CSAB: 100KB per document. DU admission: 100–200KB. Most state portals: 200–500KB. NTA / CUET documents: 200KB. Always verify the exact limit in the portal's upload instructions — it's usually printed below or beside the upload button.
Will the text and signature on my certificate stay clear?
Yes. Even at 100KB a standard A4 certificate scan remains fully readable. The tool optimizes quality at the target size — always preview before downloading to confirm.
My certificate is in PDF, not JPG. What should I do?
Take a screenshot of the PDF page (Windows: Snip & Sketch, Mac: Cmd+Shift+4, phone: screenshot) and upload that image. Then compress the screenshot to the required KB.
Can I use this for an income or domicile certificate?
Yes — any government document scan works. The same process applies: upload the image, set the KB target, preview, download.
Is my certificate safe? It has personal information.
Completely safe. Compression happens entirely in your browser. The image never reaches our servers. Your document, caste details, and personal information never leave your device.
