How to Compress a PDF for SSC, UPSC, Bank & Other Forms
Most Indian government and exam portals ask for PDF files under a specific size limit. Here's how to achieve it with our tool in 3 simple steps:
- Upload your PDF – Click the upload area above or drag & drop your file. Maximum file size: 50MB.
- Select compression level – Adjust the slider (0-100%). Moving towards the left gives higher compression (smaller size, best for government portals), while moving right maintains higher quality. Check the live size estimate.
- Download compressed PDF – Click Compress PDF. In seconds, your new PDF will be ready. Click Download PDF to save it on your device.
Pro Tip: If your original PDF is very large (10MB+), use higher compression. If the portal needs an exact KB target, adjust the slider, check the estimate, and compress.
Compress PDF to Exact KB Size – 100KB, 200KB, 300KB & More
Different Indian portals demand different exact PDF sizes. Our compressor lets you target 100KB, 200KB, 300KB, 500KB and everything in between. Here's how to hit each target precisely for the most common form requirements:
📄 Compress PDF to 100KB Online for SSC CGL & CHSL
The tightest requirement — mostly for SSC CGL, CHSL, and MTS application forms. Upload your scanned photo+signature PDF, select High Compression, and compress. If the output is still above 100KB, re-compress at the same setting. Critical tip: Scan your photo and signature at 150 DPI (not 300 DPI) before creating the PDF. This keeps the original file small and makes 100KB easily achievable without blurring.
📋 Compress PDF to 200KB Online for UPSC & State PSC Forms
The most common requirement for UPSC Civil Services, State PSC, and university admission portals. Upload your PDF, use Medium-High Compression, and watch the live output size. If you hit 190KB–210KB, you're safe. For scanned certificates and marksheets, 200KB per page is usually the maximum. Our tool compresses while keeping all text legible — essential for document verification.
📑 Compress PDF to 300KB Online for IBPS, Bank PO & RRB Forms
Many banking exams (IBPS PO, SBI PO, RBI Grade B, RRB NTPC) ask for PDFs under 300KB. Use Medium Compression for the best balance — your photo remains clear, signature stays sharp, and file size stays safely under 300KB. If you're uploading a resume PDF, Medium Compression reduces a 2MB file to ~250KB while keeping formatting intact.
🗂️ Compress PDF to 500KB Online for Passport Seva, GST & More
For Passport Seva, GST portal invoices, and DigiLocker uploads, the 500KB limit is common. Use Low-Medium Compression for these — your documents stay sharp, and text remains crystal clear. Scanned multi-page invoices (3–5 pages) can easily fit under 500KB with Medium compression.
PDF File Size Limits for Indian Portals & Exams
Here's a quick reference table of file size requirements for common Indian government and educational portals. Use our compressor to match these requirements exactly:
| Portal / Exam | Document Type | Max PDF Size | Notes |
|---|---|---|---|
| SSC CGL / CHSL | Scanned Certificates / Signatures | 100KB – 300KB | PDF containing photo + signature or certificate sheets |
| UPSC Civil Services | Application Supporting Documents | 100KB – 500KB | Separate PDFs for marksheets, categories and IDs |
| IBPS / Bank PO | Resume & Caste/EWS Certificates | 150KB – 500KB | Keep text readable; use moderate compression |
| GST Portal | Invoices, Registration & Returns | 100KB – 5MB | Scanned invoices must remain legible for audit |
| DigiLocker | Uploaded Certificates & IDs | 10MB | No issues usually, but smaller files upload faster |
| Passport Seva | Supporting Address / Birth Proof | 200KB – 500KB | Each document uploaded separately |
| University Admissions | Scanned Marksheets & TC | 100KB – 1MB | Keep text sharp for verification officers |

Compress Aadhar PDF & PAN Card PDF – For Government Portals
Two of the most frequently uploaded documents in India are the Aadhar card PDF and PAN card PDF. Whether it's for bank KYC, mobile SIM verification, income tax filing, or passport application, these PDFs must be small enough to upload while remaining clearly readable. Our compressor is built for exactly this purpose.
🪪 Compress Aadhar Card PDF Online
When you download your Aadhar from the UIDAI website, it comes as a password-protected PDF, typically 500KB–1.5MB. After unlocking it, upload the PDF here and use Medium Compression. The output will be around 200KB–400KB — small enough for any portal upload while keeping your photo, QR code, and text 100% clear. No one should ever reject your Aadhar for being blurry.
Note: You must remove the password before uploading. Use UIDAI's official PDF password (first 4 letters of your name in CAPITALS + birth year) to unlock, then compress here.
💳 Compress PAN Card PDF Online
PAN card PDFs downloaded from the NSDL/UTIITSL portal are usually 200KB–800KB. Some income tax and bank portals need them under 305KB. Upload the PDF, select Medium Compression, and download — the compressed version stays fully readable with the PAN number, photo, and signature intact. Perfect for ITR filing, bank account opening, and mutual fund KYC.
Privacy Guarantee: Your Aadhar and PAN PDFs are the most sensitive documents you own. Our tool processes everything in your browser — these files never leave your device. No server upload means zero risk of data theft or misuse.
Compress PDF for WhatsApp, Gmail & Telegram – Share Instantly
PDF Size Reducer for Gmail Attachment (25MB Limit)
Gmail's attachment limit is 25MB per email. If your PDF is even 1KB over, Gmail will force you to upload it to Google Drive and send a link — which many government portals, universities, and employers do not accept. They want the PDF as a direct attachment. Our compressor solves this:
- Upload your 26MB–50MB PDF, apply High Compression, and get it under 25MB in seconds.
- For scanned multi‑page documents (project reports, mark sheets, legal papers), use Medium Compression to keep every page legible.
- Gmail also has a total attachment limit of 25MB per email (including all files). If you're attaching multiple PDFs, compress them individually so the total stays under 25MB.
- Pro Tip: Always compress before composing the email. A 24MB PDF sends in under 10 seconds on Jio 4G; a 30MB PDF fails entirely.
Compress PDF for WhatsApp India
WhatsApp allows documents up to 100MB (Android) and 128MB (iPhone), but large PDFs take forever to upload on Indian mobile data — especially on 3G or congested 4G. Compressing a 15MB project report to ~3MB means it sends in seconds, not minutes. After compression, use our Share on WhatsApp button to send directly.
Compress PDF for Telegram India
Telegram allows up to 2GB files — generous, but your recipient may be on mobile data. A compressed PDF downloads faster and saves their daily data limit. Use Medium Compression for a good balance — Telegram groups, study channels, and job alert groups will appreciate smaller files that load instantly.
Frequently Asked Questions
Q1. How to compress PDF to 100KB online for SSC CGL?
Upload your PDF, select High Compression (slide towards left), and click Compress. If the output is still above 100KB, ensure your original PDF does not contain heavy colored graphics; scan certificates in grayscale or 150 DPI before uploading.
Q2. Is it safe to upload my Aadhar or PAN PDF here?
Absolutely safe. Our tool works completely locally in your browser. Your PDF is never uploaded to any server. The compression happens on your phone or PC memory, keeping personal data completely private.
Q3. Can I compress a scanned PDF without losing text clarity?
Yes. Use Medium Compression for scanned documents. It reduces file size while keeping letters, seal stamps, and signatures sharp. High compression may slightly blur details on scans, so preview it first.
Q4. What is the maximum PDF size I can upload?
You can upload files up to 50MB. For files larger than 50MB, consider splitting them first using our PDF Splitter, then compress each part.
Q5. How to compress PDF for GST portal upload?
GST portal invoices and registration returns should be clear but under 5MB per file. Scan at 200 DPI, combine them, and use Medium Compression. The output will be around 500KB–2MB with excellent readability.
Q6. Does compressing a PDF reduce the number of pages?
No. Our compressor only optimizes data, fonts, and images inside the file — it does not change the page count. All pages remain exactly as they were. To remove pages, use our PDF Splitter.
Q7. Can I compress password-protected PDFs?
No, password-protected PDFs cannot be compressed directly. You must first unlock them using password removal tools, then upload the unlocked PDF for compression.
Q8. How to compress PDF on mobile without any app?
Just open this page on your mobile browser (Chrome/Safari), tap the upload box, choose the document from your gallery or file manager, select compression strength, and download. Works on Android, iOS, and Jio Phones.
Q9. Why does my PDF size increase after compression?
If a PDF has already been heavily optimized and compressed, attempting further compression can occasionally append metadata that slightly increases size. In such cases, keep the original file.
Q10. How to compress PDF for DigiLocker upload?
DigiLocker accepts PDFs up to 10MB per document. Most Aadhar, marksheet, and certificate PDFs are already under this limit, but if yours is larger, use Medium Compression. This preserves the QR code, photo, and seal clearly — essential because DigiLocker documents are used for official verification. Always preview the compressed PDF before uploading.
Q11. How to compress PDF for Passport Seva (passport application)?
Passport Seva requires each supporting document PDF to be under 500KB. For scanned Aadhar, PAN, and address proof PDFs, use Medium Compression. If a scanned 10th marksheet PDF is 2MB, use High Compression to bring it under 500KB. Ensure all text remains readable — the passport office will reject blurry documents. Important: Compress each document separately, do not merge all into one PDF.
Q12. How to compress PDF for IBPS bank form photo & signature?
IBPS requires the photo and signature to be in one combined PDF under 300KB. Scan your photo and signature on a single A4 page at 150 DPI, save as PDF, then use High Compression. The output will be around 150KB–250KB — well within limits. Both photo and signature must be clearly visible; preview before submission.
Q13. How to compress PDF for university admission form?
Indian universities (DU, Mumbai University, Anna University, etc.) typically ask for scanned marksheets and certificates as separate PDFs under 200KB–500KB each. Scan each document at 150–200 DPI, create individual PDFs, then use Medium Compression. This keeps the grades, university seal, and student photo sharp while meeting the strict file size limits of admission portals.
Q14. How to compress PDF for scholarship form (NSP, state portals)?
National Scholarship Portal (NSP) and state scholarship portals often cap PDF uploads at 200KB per document. This includes income certificate, caste certificate, and marksheets. Scan at 150 DPI, create separate PDFs for each document, and apply High Compression. Check each output — scholarship applications are rejected for illegible documents, so ensure every detail is readable even at 200KB.
