PDF TOOL
Compress PDF for exam form upload
Reduce PDF file size for exam portal document upload — mark sheets, certificates, ID proof. Files up to 50MB are compressed right in your browser; larger files (up to 2GB) are compressed securely on our server and deleted immediately. No login.
When do you need to compress PDF for exam forms?
Always verify document size limits from the official notification — limits vary by recruitment cycle.
How to compress a PDF for an exam form
- Upload the PDF you need to shrink — a scanned certificate, mark sheet bundle or ID proof.
- Pick the target size or compression level. Aim just under the limit in your notification.
- Download the smaller PDF and check it still opens clearly before you upload it.
Why the portal rejects your PDF
Upload fields set a maximum file size. A PDF built from full-resolution phone photos or a 600 DPI scan is often several times that limit, so the portal refuses it without saying why.
Compressing re-encodes the images inside the PDF at a lower size while keeping the pages readable.
How small should it be
Use the figure in your own official notification — it differs by exam and by document type. Leave a small margin below it so a slow upload does not round up over the limit.
If the text turns blurry
You have compressed too far. Redo it at a higher target size, or rescan the original at 200–300 DPI in black and white, which is smaller than a colour scan to begin with.
Frequently asked questions
How do I reduce a PDF to under the exam upload limit?
Upload the PDF, choose a target size just below the limit in your notification, and download the compressed file. Confirm it still reads clearly before uploading.
Will compressing make my certificate unreadable?
Not if you stay near the required size. Very aggressive compression can blur small text — if that happens, use a higher target or rescan the original at 200–300 DPI.
Is my PDF uploaded to a server?
The PDF compressor sends the file over an encrypted connection to process it and deletes it straight after. It is not stored.
What size limit do exam forms use for PDFs?
It varies by exam and is stated in the official notification, commonly somewhere between 500 KB and 2 MB per document.

Compress PDF — common questions
How do I compress a large PDF (up to 2GB)?
Upload your PDF and the tool reduces its size automatically. Files up to 50MB are compressed in your browser; larger files up to 2GB are compressed securely on our server and deleted immediately after. Pick Maximum, Recommended or Light compression depending on how much quality you want to keep.
How much can the file size be reduced?
It depends on the PDF. Documents with high-resolution scanned images or photos compress the most. PDFs that are already optimised may shrink only a little — in that case the tool keeps the original so you never get a larger file.
Will compressing reduce the quality of my PDF?
Recommended quality keeps documents clearly readable while cutting size. Use Light for near-original quality, or Maximum when you need the smallest possible file for an upload limit.
Is it free and is my file kept private?
Completely free, no login. Files under 50MB never leave your device. Larger files are sent over an encrypted connection, compressed, and deleted right away — nothing is stored.
